Answer:
the y-intercept is 7
Step-by-step explanation:
y=mx+b
m=slope
b= y-intercept
The volume of a crate is b x l x h. Reverse it to get 3 times 6 times h = 72. 3 times 6 is 18, so you know 18h=72. Divide both sides by 18 to get h = 4 ft.
D, 8.5
a squared + b squared = c squared for the sides and hypotenuse of the triangle.
6^2 + 6^2 = c^2
36 + 36 = c^2
72 = c^2
c = square root of 72, 8.49
The functions will be defined as y = x² if 0 ≤ x < 3, y = -x + 10 if 3 < x ≤ 6, and y = x + 2 if 6 ≤ x ≤ 10.
<h3>What is a function?</h3>
A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
The graph is given below.
The function can be defined as
The parabolic equation will be
f(x) = x²
The equation of the absolute function will be
f(x) = |x - 6| + 4
Then we have

Answer:
(-4,-19)
Step-by-step explanation:
y = x² + 8x - 3
y = x² + 2(x)(4) + 4² - 4² - 3
y = (x + 4)² - 16 - 3
y = (x + 4)² - 19
Vertex: (-4,-19)
