Answer:
Slope = 2 and y-intercept = 8
Step-by-step explanation:
Use slope formula
m=y2-y1/x2-x1
m=16-12/4-2
m=4/2
Simplify
m=2
To find the y-intercept use point slope formula
y-y1=m(x-x1)
y-12=2(x-2)
y-12=2x-4
Add 12 to both sides
y=2x+8
So, 8 is the y-intercept or (0,8)

pagué 250 pesos del recibo del agua y 490 pesos de la luz pero no recuerdo cuanto pague del telefono si traia $1000 y me sobraron 74.50 pesos ¿por cuanto era el recibo del telefono?
Queremos encontrar y resolver una ecuación algebraica con los datos dados.
Veremos que se pagaron 185.50 pesos del telefono.
La información que se nos da es:
Se pagan 250 pesos de agua.Se pagan 490 pesos de agua.No se sabe cuanto se pago del telefono, representemos esto con X.Sabemos que de 1000 pesos sobraron 74.50, entonces podemos escribir:
1000 - 250 - 490 - X = 74.50
Ahora podemos resolver esto para X.
1000 - 250 - 490 - X = 74.50
260 - X = 74.50
X = 260 - 74.50 = 185.50
Así podemos concluir que se pagaron 185.50 pesos del telefono.

Quadratic Function Question
You are recently promoted as the chief traffic management officer of a major city in the country. Based on recent data, you learned that one of the leading causes of road accidents is overspeeding.
In your desire to minimize road accidents, you went out to observe how traffic management rules are implemented on the streets. Your attention was caught by a fast-moving car that seemed to be breaking the speed limit of 100 kilometers per hour(km/hr.), and so you followed it along the highway. After a short time, the driver of the car noticed you and started to slow down. Eventually, he stopped on the side of the road.
Supposed the speed of the car had been noted during this time and is modeled by the quadratic equation y = 3x² + 17x - 20, where y represents the speed of the car in km/hr. and x represents the number of minutes after you started following the car. How long did it take for the car to be under surveillance before it could finally stop on the side of the road? Did the driver of the car really break the speed limit of 100 km/hr.? Explain.
You will prepare an observation report highlighting whether it is necessary to come up with more stringent implementation of traffic rules based on the outcome of your analysis of the problem that you encountered on the road.

By what least number should 4851 be divided to get a perfect square number ? Also find the square root of the square number so obtained ?
Answer:
The least number should 4851 be divided to get a perfect square number = 11
The square root of the obtained perfect square number is 21
Step-by-step explanation:
Given number = 4851
It can be written as
4851 = 3×1617
4851 = 3×3×539
4851 = 3×3×7×77
4851 = 3×3×7×7×11
4851 = (3×3)×(7×7)×11
It is clear that We should divide the given number by 11 then we get a perfect square number.
4851/11 = 441
441 = 21×21
=> 441 = 21²
=> √441 = √(21²)
=> √441 = 21
Answer:-The least number should 4851 be divided to get a perfect square number = 11
The square root of the obtained perfect square number is 21
Used Method :-→ Prime Factorization Method
Answer:
11 is the least number and the when you take the square root of the number you get 21
Step-by-step explanation:
The easiest way to solve this problem is guess and check.
First of all, a perfect square NEEDS to be a WHOLE number
Since 4851 is odd, you cannot divide it by an even number evenly, as it would result in a number with a remainder or leftover decimal amount.
This means you cannot divide by 2, 4,8...etc
We just have to guess and check odd numbers starting at 3.
4581/ 3 = 1527 sqrt(1527) = 39.07684737 decimal so not this one
4581/ 5 = 916.2 decimal so not this one
4581/ 7 = 654.4285714 decimal so not this one
4581/ 9 = 509 sqrt(509) = 22.56102835 decimal so not this one
4581/ 11 = 441 sqrt(441) = 21
This is the first instance where 4581 is divisible by a number that yields a perfect square, so 11 is the least number and the square root of the result is 21.

Solve -4(10 + 3x) - (x + 8) = -9. Check your solution.
Answer:
x = -3
Step-by-step explanation:
Given the equation, -4(10 + 3x) - (x + 8) = - 9:
Distribute -4 into (10x + 3x), and - 1 into (x + 8):
-4(10 + 3x) - (x + 8) = - 9
-40 -12x - x - 8 = -9
Combine like terms:
-48 - 13x = -9
Add 48 to both sides:
-48 + 48 - 13x = -9 + 48
-13x = 39
Divide both sides by -13:
[tex]\frac{-13x}{-13} = \frac{39}{-13}[/tex]
x = -3
Therefore, x = -3

1/2 tsp of salt makes 16 cookies. how many salt would you need for 55 cookies?
Answer:
Step-by-step explanation: 1/2x=16
16x4=64, Although this is not exactly 55 cookies, you can either make more or less. So you need 4 salt, to make 55.
Answer:
[tex]\frac{55}{32}[/tex] tsp
Step-by-step explanation:
To find out how much salt you would need to make 55 cookies, you need to find how much salt makes 1 cookie:
If [tex]\frac{1}{2}[/tex] tsp of salt makes 16 cookies, then ([tex]\frac{1}{2}[/tex] ÷ 16) tsp of salt will make 1 cookie.
But how much is [tex]\frac{1}{2}[/tex] ÷ 16?
To divide fractions with different denominators easily, use the SFM method:
S - Skip
F - Flip
M - Multiply
[tex]\frac{1}{2}[/tex] ÷ [tex]\frac{16}{1}[/tex] First, Skip your focus to the 2nd number. This is what will be changed.
[tex]\frac{1}{2}[/tex] ÷ [tex]\frac{1}{16}[/tex] Next, Flip the numerator and denominator.
[tex]\frac{1}{2}[/tex] × [tex]\frac{1}{16}[/tex] Finally, multiply the two numbers together.
[tex]\frac{1}{32}[/tex]
[tex]\frac{1}{32}[/tex] tsp of salt will make 1 cookie.
Now to find the amount needed for 55 cookies:
To find the amount of salt needed to make 55 cookies, multiply [tex]\frac{1}{32}[/tex] × 55.
[tex]\frac{1}{32}[/tex] × [tex]\frac{55}{1}[/tex] = [tex]\frac{55}{32}[/tex]
Because the fraction cannot be simplified further, the amount of salt that is needed to make 55 cookies is [tex]\frac{55}{32}[/tex] tsp.
What is the solution to m(n(x))? m(x)=10x−9 n(x)=7x2+4
The composite function m(n(x)) is 70x²+ 19
Given the functions
m(x)=10x−9
n(x)=7x²+4
We need to get the composite function m(n(x))
m(n(x)) = m(7x²+4)
To get m(7x²+4), we need to replace x as 7x²+4 in function m(x) as shown:
m(7x²+4) = 10(7x²+4) - 9
m(7x²+4) = 70x²+ 28 - 9
m(7x²+4) = 70x²+ 19
Hence the composite function m(n(x)) is 70x²+ 19

Answer:
Disciminant of f = 0
x-intecept = [tex](\frac{3}{2}, 0)[/tex]
Step-by-step explanation:
Given the quadratic function, -4x² + 12x - 9
where a = -4, b = 12, and c = -9
The discriminant, b²- 4ac, is the expression inside the radical (numerator) of the quadratic formula:
[tex]x = \frac{-b +/- \sqrt{b^{2}-4ac} }{2a}[/tex]
The first part of your given problem asks for the discriminant. Substitute the values for a, b, and c:
b²- 4ac = 12² - 4(-4)(-9) = 144 - 144 = 0 → This implies that the quadratic function has one real root.
Therefore, the disciminant of f is 0.
Next, the given problem asks for the x-intercepts. The x-intercept is the point on the graph where it crosses the x-axis. As I mentioned earlier, the function has one real root. Therefore, it means that there is only 1 x-intercept. To find out what the x-intercept is, use the quadratic formula:
[tex]x = \frac{-b +/- \sqrt{b^{2}-4ac} }{2a}[/tex]
[tex]x = \frac{-12 +/- \sqrt{12^{2}-4(-4)(-9)} }{2(-4)}[/tex]
[tex]x = \frac{-12 +/- \sqrt{144 - 144} }{-8}[/tex]
[tex]x = \frac{-12}{-8} = \frac{3}{2}[/tex]
Therefore, the x-intercept is [tex](\frac{3}{2}, 0)[/tex].

Step-by-step explanation:
The two angels are congruent, meaning they're the same. So its just what multiplied by 2 gets 74. So 74 divided by 2 is 37.
I hope I could help. Enjoy your day! Maybe brainiest if this was right?
No pressure! :)
Answer:
37
Step-by-step explanation:
This is a vertical angle, meaning 74 and 2x would be equivalent to each other. So we have to make 2x equal to 74. We set up an equation, 2x = 74. Divide 2 for both sides; 74 divided by 2 = 37; 2x divided by 2 (2 cancels out, leaving x alone). Therefore, x = 37.
To check, substitute x with 37. 37 times 2 is 74, and since the left is 74 the right also have to be 74.

9/10 - (1/8-3/10)= please help me through steps
Answer:
43/40 or 1 3/40
Step-by-step explanation:
9/10 - (1/8 - 3/10)
Remember, we have to solve what's in the parentheses first!
To find 1/8 - 3/10, we must find the least common multiple of the denominators, which is 8 and 10.
Let's list the multiples of 8 and 10
Multiples of 8: 8, 16, 24, 32, 40, 48, 56...
Multiples of 10: 10, 20, 30, 40, 50, 60...
We found a match! 40 is a multiple of both 8 and 10, so we can use that.
To make the denominator 40 for 1/8, we have to multiply both the numerator and denominator by the same number, and the denominator must equal 40 after.
So,
8 times what equals 40?
To make it easier, we can do 40 / 8, which is 5.
That means we multiply the denominator and numerator by 5, so we get 5/40 - 3/10.
If you do the same thing for 3/10, you get 12/40.
Our equation is much easier!
We can easily do 5/40 - 12/40, which is -7/40.
Now, we do 9/10 - (-7/40)
Remember, two minuses right next to each other make a plus!
Our equation is now 9/10 + 7/40.
If you do the least common multiple for 9/10, you get 36/40.
Finally, we do 36/40 + 7/40, which is 43/40.
If it's asking for a mixed number, it would be 1 3/40.
Therefore, 9/10 - (1/8 - 3/10) equals 43/40 or 1 3/40!
