Answer: D) g(x) is the graph of f(x) compressed vertically</h3>
The input is x while the output is y = f(x). If we multiply both sides of y = f(x) by 2/3, then we'll get (2/3)y = (2/3)f(x) = (2/3)x^2
We see that the new outputs are 2/3 the size of the original. So the graph is shorter and has been vertically squished or compressed. If we multiplied both sides by some number larger than 1, then the graph will be vertically stretched.
No reflection has been done because that only happens if we multiplied both sides by a negative value. The negative flips things around (from positive to negative or vice versa).
Hello,
A: 4 , 4 , 4 not right triangle
B: 4 , 6.93 , 8 or 4²+6.93²=64,0249 ≈64=8²
C: 11.2 , 16.2 , 19.2 or 11.2²+16.2²=387,88 =(19,69...)²
The best choice is B
Answer:
-14y + 30
Step-by-step explanation:
Tell me if I am wrong but I think this is it.
Solve x+3y=-1 for x:
Add -3 to both sides
x+3y+-3y=-1+-3y
x=-3y-1
Substitute -3y-1 for x in 2x+2y=6
2x+2y=6
2(-3y-1)+2y=6
Simplify both sides of the equation
-4y-2=6
Add 2 both sides
-4y-2+2=6+2
-4y=8
Divide both sides by -4
-4y/-4=8/-4
y=-2
Substitute -2 for y in x=-3y-1
x=-3y-1
x= (-3)(-2)-1
Simplify both sides of the equation
x=5
Answer : D
x=5 and y=-2
I hope that's help and have a great night !
