Answer:
Step-by-step explanation:
Let the quadratic function be
y=a(x+4)²-1
∵(-7,8) lies on it.
8=a(-7+4)²-1
8+1=a(-3)²
9a=9
a=9/9=1
so quadratic function is
f(x)=1(x+4)²-1
or
f(x)=x²+8x+16-1
so quadratic function is
f(x)=x²+8x+15

For m = 0.6213,

For m = -3.6213,

Therefore, the equation has no extraneous solution.
youre answer is b
point slope formula is y-y1=m(x-x1)
m=slope
x1= coordinate x
y1= coordinate y
Answer:
B) 4 cm
Step-by-step explanation:
Pentagon ABCDE is 1.75 times larger than Pentagon LMNOP. In Pentagon ABCDE, side AB is 7 cm. The side across of it (DE) is also 7. Side DE is Side OP on Pentagon LMNOP. To solve for it, divide 7/1.75 to get 4.

A function assigns the values. The table can be represented by a function.
<h3>What is a Function?</h3>
A function assigns the value of each element of one set to the other specific element of another set.
No, the number of videos kept on Ruby's friends' phones cannot be expressed as a function of the number of songs. A function produces a distinct result for each input. When the input is 125, we get two distinct results. As a result, the table does not represent a function.
Hence, the table can be represented by a function.
