You are walking along a path y= 2x + 12 and your
best friend is walking along 4x + y = 6. At what point will
you cross paths?
Answer:
(-1,10)
Step-by-step explanation:
At the point when the paths cross, the respective x and y values of each equation will be equal.
Your path is y=2x+12, and your friends path is 4x+y=6. Sub 2x+12 in for y (from your path's equation) into your friends equation to find the value of x:
4x+2x+12=6
6x=-6
x=-1
y=2x+12
y=2(-1)+12=10
So you will cross paths at (-1,10)
Si en un examen 27 preguntas son correctas el 90%, cuántas preguntas son en total?
Respuesta:
30
Explicación paso a paso:
Número total de preguntas = 100%
Número de preguntas correctas = 27
Porcentaje de aciertos = 90%
Por eso,
Si 90% = 27
Luego ; 100% = x
Multiplicar en cruz:
0,9 veces = 27
x = 27 / 0,9
x = 30
Número de preguntas = 30

The answer to the above question
Answer:
Step-by-step explanation:
Since our interval is given as it is, we are in QIII. That interval is equivalent to 270 degrees to 360 degrees, which is QIII. If we draw this right triangle in QIII and label it accordingly, the side adjacent to the reference angle is sqrt2 and the hypotenuse is 2. We know this because the cosine ratio is defined as the side adjacent to the reference angle over the hypotenuse of the right triangle. That means that we have to find the missing side in order to determine the other 2 main trig ratios. Using Pythagorean's Theorem, we have
[tex]2^2=\sqrt{2}^2+b^2[/tex] and
[tex]4=2+b^2[/tex] so
[tex]b=\sqrt{2}[/tex]. But since it is for a value that, in QIII is negative, it is [tex]-\sqrt{2}[/tex]
Now we can find the sin and tan of that reference angle. Sin is defined as the side opposite the reference angle over the hypotenuse, so
[tex]sin\theta=\frac{-\sqrt{2} }{2}[/tex] and tan, which is defined as side opposite the reference angle over the side adjacent to the reference angle, then
[tex]tan\theta=\frac{-\sqrt{2} }{\sqrt{2} }=-1[/tex]

Sheldon spins the two spinners below one time what are the chance he will spin 3 or c ?
Answer:
[tex]P(3\ or\ c) = 0.45[/tex]
Step-by-step explanation:
Given
See attachment for spinner
Required
[tex]P(3\ or\ c)[/tex]
From the first spinner, we have:
[tex]S = \{1,2,3,4,5\}[/tex] --- Sample Space
[tex]n(S)=5[/tex]
So, P(3) is:
[tex]P(3) = \frac{n(3)}{n(S)}[/tex]
[tex]P(3) = \frac{1}{5}[/tex]
[tex]P(3) = 0.20[/tex]
From the second spinner, we have:
[tex]S = \{a,b,c,d\}[/tex]
[tex]n(S) = 4[/tex]
So, P(c) is:
[tex]P(c) = \frac{n(c)}{n(S)}[/tex]
[tex]P(c) = \frac{1}{4}[/tex]
[tex]P(c) = 0.25[/tex]
The required probability is then calculated as:
[tex]P(3\ or\ c) = P(3) + P(c)[/tex]
[tex]P(3\ or\ c) = 0.20 + 0.25[/tex]
[tex]P(3\ or\ c) = 0.45[/tex]
3 x 1/2 in fraction form
Answer:
3*1/2= 3/2
Step-by-step explanation:
[tex]\frac{3}{1}[/tex]*[tex]\frac{1}{2}[/tex] = 3/2
3*1/2= 3/2
3 is equal to 3/1
we then directly multiply
equation: (3/1)(1/2)
(3/1)(1/2)
3*1 = 3
1*2= 2
3/2 or 1 1/2.
How do you write in fraction form?
Decimals can be written in fraction form. To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenth place, so we place 6 over 10 to create the equivalent fraction, 6/10.

Step-by-step explanation:
GIVEN :-
Slope of the line (denoted by 'm') = 1y-intercept of the line (denoted by 'c') = 5TO FIND :-
Equation of line in slope-intercept formFACTS TO KNOW BEFORE SOLVING :-
Lets say there's a line whose slope is 'm' & y-intercept is 'c'. So, the equation of line in slope-intercept form is → [tex]\boxed {y = mx + c}[/tex]
SOLUTION :-
By using the basic idea of slope-intercept form , the equation of line given in the question is :-

if n is an integer,what is the sum of the next three consecutive even integers greater than 2n?
Answer:
6n + 12
Step-by-step explanation:
Given an integer n, the 3 consecutive even integers greater than 2n are 2n+2, 2n+4 and 2n+6
Taking their sum;
Sum = (2n+2)+(2n+4)+(2n+6)
Sum = 2n+2n+2n+2+4+6
Sum = 6n + 12
Hence the sum of the 3 consecutive even integers greater than 2n is 6n+12

Calculate the area of triangle ACD.
You must show all your working.
Answer:
216 cm²
Step-by-step explanation:
Area of ∆ACD = ½*CD*CA
CD = 24 cm
CA = ?
Use pythagorean theorem to find CA.
Thus:
CA² = AB² + BC²
Substitute
CA² = 10.8² + 14.4² = 324
CA = √324
CA = 18 cm
Area of ∆ACD = ½*CD*CA
Substitute
Area = ½*24*18
= 216 cm²

Answer:
O.75
Step-by-step explanation:
The value of x in the equation 1.5(4)^2x is equal to 12 is 3/4 after equation the power of same base.
What is integer exponent?In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.
We have an equation:
[tex]\rm 1.5(4)^2^x=12[/tex]
[tex]\rm (4)^2^x=8[/tex]
[tex]\rm (2^2)^{2x}= 2^3[/tex]
[tex]\rm 2^{4x}=2^3[/tex]
4x = 3 (equating powers of same base)
x = 3/4
Thus, the value of x in the equation 1.5(4)^2x is equal to 12 is 3/4 after equation the power of same base.
