Answer:
As an equation: 15 × x = -75
Solved: x = -5
Step-by-step explanation:
15*x = -75
[tex]\frac{15*x}{15}[/tex] = [tex]-\frac{75}{15}[/tex], Divide by 15 on both sides to solve for x
x=[tex]-\frac{75}{15}[/tex], The 15 in the numerator cancels out with the denominator
x= -5, because 75/15=5
If g(x) = 3/2x + 4, what is the value of g(2)?
A. 10
B. 7
C. 5
D. 3.5
Answer:
The answer is option BStep-by-step explanation:
[tex]g(x) = \frac{3}{2} x + 4 \\ [/tex]
To find g(2), substitute the value of x that's 2 into g(x). That is for every x in g(x) replace it with 2
We have
[tex]g(2) = \frac{3}{2} \times 2 + 4 \\ = 3 + 4[/tex]
We have the final answer as

a ratio of angel fish at a store is 5:4. the ratio of angel fish to goldfish is 4:3 . There are 60 clown fish at the pet store
how many angel fish are there?
how many goldfish are there
Answer:
an i oop
Step-by-step explanation:
Answer:
So if there are 60 clownfish and the ratio from clownfish to angelfish is 5:4, this is the equation you are looking at:
5:4 = 60:?
To find ? you have to do 60 divided by 5 which equals 12 and multiply it times 4 to see how many angelfish there will be if there are 60 clownfish.
12 x 4 = 48
So if there are 60 clownfish there will be 48 angelfish. The ratio is 60:48
For the next one, same thing if there are 48 angelfish, then you are looking at this equation:
4:3 = 48:?
Again, we solve like we did the last one.
48 divided by 4= 12
3 x 12= 36
So, if there are 48 angelfish there will be 36 goldfish. The ratio is 48:36
I hope this helps:)

Okay so, to get C you add the ones inside the triangle together.
42+58=100 Then the last angle will be 80, because when you add the three inside the triangle, you should get 180
42+58+80=180
To get D, you have to subtract 180 and 58, because 58+d will be a straight angle.
180-58=121
To get B and A, you would also have another straight angle (c, b, and a)
180-80=100
I believe that B=A, so, with the remaining 100, both A and B equal 50.
50+50+80=180
Does this help??
Answer:
a° = 58°
b = 42°
c° = 80°
d° = 122°
Step-by-step explanation:
d° can be found because a straight line has an angle of 180°.
180° - 58° = 122°
Because the angles of a triangle add up to 180°, we can find c°
58° + 42° = 100°. 180° - 100° = 80°
You can find a° subtracting 180 and d°, which is 122. 180° - 122° = 58°
You can do the same thing for b°. 180° - 42° = 138°. 180° - 138° = 42°
You can check this because b° + c° + a° should equal 180°.
58° + 42° + 80° = 180°
I hope this helps :)

Which equation represents the vertical line passing through (7,-3)?
A.
x = -3
B.
y = -3
C.
x = 7
D.
y = 7
Answer:
C. [tex]x=7[/tex]
Step-by-step explanation:
So we know that a vertical line is represented by [tex]x=[/tex] so we can already rule out two of the options. We also know that since the line runs vertically, all points will start with the same [tex]x[/tex] coordinate. This means that the correct answer is [tex]x=7[/tex]

Create the polynomial which has roots 3and 2
Answer:
f(x) = x² - 5x + 6
Step-by-step explanation:
Given a root of a polynomial x = a then the factor is (x - a)
Here the roots are x = 3 and x = 2 , thus the corresponding factors are
(x - 3) and (x - 2)
The polynomial is then the product of the factors, that is
f(x) = (x - 3)(x - 2) ← expand using FOIL
= x² - 5x + 6

In the graph of an inequality, the area above a solid line through the points (−5, 2) and (3, 2) is shaded.
Which inequality does this graph represent?
A. y ≥ 2
B. y ≤ 2
C. y 2
Answer:
A. y ≥ 2
Step-by-step explanation:
First the line is solid, a complete line not dotted so the inequality sign to use is : ≥ or ≤
The points have their y-coordinate vale as 2, (−5, 2) and (3, 2), this means the line crosses the y-axis at y=2 but because the shaded part is above this line, then the correct inequality will be :
y ≥ 2
See attached graph below.

At the beginning of the school year, Jamie had $500 in her savings account. She wants to have at least $200 left in the account at the end of the school year. Each week, she withdraws $30 for spending money. To determine how many weeks she can spend $30, Jamie wrote and solved this inequality. 500 − 30x ≥ 200 −500 −500 −30x ≥ −300 x ≥ 10 Review Jamie's work. What was her error?
Answer:
Step-by-step explanation:
Given the inequality solved by H=Jamie expressed as:
500 − 30x ≥ 200
We need to calculate the range of x of the inequality to determine the number of weeks she can spend $30 as shown:
500 − 30x ≥ 200
Subtract 500 from both sides
500 − 30x - 500≥ 200 - 500
− 30x ≥ -300
Divide both sides by -30
− 30x/-30 ≥ -300/-30
x ≤ 10 (note that the inequality sign changes after dividing both sides by a negative sign)
Jamie's error was that she didn't change the sense of inequality after dividing both sides by -30 hence rendering her solution incorrect
Hence the number of weeks is less than or equal to 10.
Answer:
Answer is B
Step-by-step explanation:
Jamie should have reversed the inequality when using the division property of inequality. is the right answer hope it helps

The phrase that best represents six times the quantity of four plus a number is 6(4) + n.
What is a numerical expression ?A numerical expression is a form where we express a statement by number and their operations.
According to the given phrase six times the quantity four which is 6(4) plus a number.
6(4) + n.
What we have done here is we formed a numerical expression from a given statement.
Suppose we have given sum of 4 and thrice of a number is 10.
So, 4 + 3n = 10
3n = 10 - 4
3n = 6
n = 2.
So the number is 2.

I take two blocks at random. What is the probability that these two blocks have exactly two of these four properties the same?
Answer: 0.54
Step-by-step explanatio;
We would have three in common out of 4 characteristics (4 out of 4 is not possible). There are 4 possible ways to share 3 out of 4 characteristics.
Denoting the characteristics as {M,C,Si,Sh} so P(B2={1,1,1,0}|B1={1,1,1,0}) is the probability that box 2 shares its first three characteristics with box 1 given that box one has characteristics
We now have
P(B2 has 3 elements in common with B1)=P(B2={1,1,1,0}|B1={1,1,1,0})xP(B1={1,1,1,0})+P(B2={1,1,0,1}|B1={1,1,0,1})xP(B1={1,1,0,1})+P(B2={1,0,1,1}|B1={1,0,1,1})xP(B1={1,0,1,1})+P(B2={0,1,1,1}|B1={0,1,1,1})xP(B1={0,1,1,1})
P(B2 has 3 elements in common with B1)=(4x5x24+3x4x30+2x3x40+1x2x60)1120x119= 0.084
which is close enough to the value from the simulation code (modified to count the number of 3-ties)
Now, I use the same reasoning to compute:
P(B2 has 2 or more elements in common with B1)=(19x20x6+11x12x10+9x10x12+14x15x8+7x8x15+5x6x20)1120x119= 0.54
Equation: (2-1)((3-1)+(4-1)+(5-1)) + (2)((3)+(4)) + (12) = 35 with a total of 119 possibilities.

Answer:
2^4
2 * 2 * 2 * 2
Step-by-step explanation:
In the question above :
Write an exponential expression:
Base = number between 0 and 10
Exponent = number different from the base between 0 and 10
Let base = 2
Let exponent = 4
Hence, exponential expression will be
Base^exponent
2^4 (standard form)
