Answer:
3
Step-by-step explanation:
We know that m= -3 so we plug it into our equation
[tex]-3^{2}[/tex]+5*-3+9
NOTE: in an equation when a letter is touching a number that means to multiply, that's how i got 5*-3 in the equation.
Now we solve!
[tex]-3^{2}[/tex]+5*-3+9 = 3

Answer:
x^3 -2x^2 + 2x -2 c(2) = - 4Step-by-step explanation:
Given
f(x)=2x^3 - 4x^2 + 2g(x)=x^3 - 2x^2 - 2x + 4To find
f(x)-g(x)Solution
f(x)-g(x)=2x^3 - 4x^2 + 2 - (x^3 - 2x^2 - 2x + 4) =2x^3 - 4x^2 + 2 - x^3 + 2x^2 + 2x - 4 =x^3 -2x^2 + 2x -2==================
c(x) = -2xc(2) = -2*2 = - 4-2 (k - 9)= -6
What’s the answer
Answer:
12
Step-by-step explanation:
distribute equation
-2 times k = -2k
-2 times -9 = 18
so -2k+18=-6
solve
subtract 18 from both sides
-2k= -24
divide -2 from both sides
k =12
Answer:
k=12
Step-by-step explanation:
-2(k-9)=-6
divide both sides
k-9=3
move the k to the right
k=3+9
add 3+9
k=12
Solve for v
7 - V = 3
Answer:
7 - V = 3
take away 7 from both sides
-V = -4
V = 4
Step-by-step explanation:
Hey there!
7 - v = 3
-v + 7 = 3
SUBTRACT 7 to BOTH SIDES
-v + 7 - 7 = 3 - 7
SIMPLIFY IT!
-v = 3 - 7
-v = -4
DIVIDE -1 to BOTH SIDES
-v/-1 = -4/-1
SIMPLIFY IT!
v = -4/-1
v = 4/1
v = 4
Therefore, your answer is: v = 4
Good luck on your assignment & enjoy your day!

Fifteen more than a number is written as...?
Answer:
x + 15
Step-by-step explanation:
Since I don't know what this number is, I'm going to use the variable x to substitute for the value of the unknown number.
So it would just be x + 15 because addition is the operation of adding and the key words are usually more. Since one of the numbers is unknown, we can't get an answer like "100" because x is undefined.
Say x=100, then the number would be written as 115 in it's simplest form but you could also write it as 100+15. So I'm just using substitution.
Answer:
x+15
Step-by-step explanation:
Since it says "than a number"
What number is it?
We don't know.
We will say thats a variable.
What variable?
Well it really can be anything. ONLY LETTERS
Lets do a x
Now the problem changed.
Fifteen more than x is written as...?
It says "more"
You use plus.
Now the problem changed.
Since is written as... is your answer so yeah
15+x is the problem.
There you go the answer!
People writes the variable first so:
x+15
The answer is x+15
A blueprint for a house states that 2 inches represents 8 feet. If the width of a window is 2.5 inches on the blueprint, what is the width of the actual window?
Answer:
10 feet. You can prove this by dividing 8 by 2, with this you find that 1 inch on the blueprint is equal to 4 feet. then take half of 4(2), and add it to 8 to get your answer.

Step-by-step explanation:
90
-------------------
10 + (3^2 - 4)
first we look at the parenthesis. take 3 to the second power, and it equals 9
90
------------------
10 + (9 - 4)
next, still in the parenthesis you subtract 4 from 9

Answer:

Step-by-step explanation:
To be a function, the line has to pass the vertical line test. This means that when a vertical line is passed through every x value, it will only cross the graphed line once.
To help: draw vertical lines through each graph.
In graph W: the line would pass through the top and bottom of the circle - not a function
In graph X: the line passes once through every area - a function
In graph Y: the line passes through the top curve as well as the bottom curve - not a function
In graph Z: the line passes through the curves multiple times - not a function
