Question 4:
2x + 3y = 17 -- equation 1
5x + 6y = 32 -- equation 2
(equation 1) * 2
4x + 6y = 34 -- equation 3
(equation 2) - (equation 3)
x = -2 -- equation 4
plug (equation 4)'s value of x into (equation 1)
2(-2) + 3y = 17
3y - 4 = 17
3y = 21
y = 7
Thus the answer is x = -2 and y = 7
Question 5:
The vertex form of a quadrilateral looks like this:
[tex]y = a(x-h)^2 + k[/tex]
a : coefficient of [tex]x^2\\[/tex](h,k): coordinate of the vertex.The x-coordinate of the vertex is equal to '-b/2a'. Where b is the
coefficient of x, so:
[tex]h = -\frac{b}{2a} =-\frac{-8}{2*1} =4[/tex]
There is also another formula to find the y-value of the vertex
coordinate, but the easier way to find it is to plug it into the original
equation:
[tex]k=(4)^2-8(4) + 12= 16 -32 + 12 = -16 + 12 = -4[/tex]
Since we know now that h = 4 and k = -4 and that a = 1, lets plug it into
the original equation.
[tex]y = 1*(x-4)^2 - 4 =(x^2-4)-4[/tex]
Thus the answer is [tex]y = (x-4)^2 -4[/tex]
Hope that helps!

What is dilation?
Dilation is the increase or decrease in the size of an figure or object.
A dilation with a scale factor of 2 is applied to the three line segments shown to form P'Q', A'B', and M'N'.
Hence:
P'Q' = scale factor * PQ = 2 * 2 = 4 cm
A'B' = 2 * 1.5 = 3 cm
M'N' = 2 * MN = 2 * 3 = 6 cm
The value of the dilated line segments P'Q', A'B' and M'N' are 4 cm. 3 cm and 6 cm

Answers
Answer:
Step-by-step explanation:
1) Divide the diameter in half to make the radius, which equals 2.85 as r.
2) Plug in the radius(r) and height(h) with the correct numbers.
3) Simply solve
V = π(2.85)² × 13.1 ÷ 3
V= 25.52 × 13.1 ÷ 3
V= 334.312 ÷ 3
V= 111.4373+

Answer:
99.95 + 19.99x ≤ 125.79 + 15.99y
Step-by-step explanation:
Given:
Luke bought a video game system that costs $99.95 and games that cost $19.99 each.
Bella bought a game system that costs $125.79 and games that cost $15.99 each.
Luke spent no more than what Bella spent.
To Find:
Which inequality represents this situation?
Solve:
Let Luke bought = x.
Let Bella bought = y.
How much Luke paid = $99.95 + $19.99 × x = $99.95 + $19.99x
How much Bella paid = $125.79 + $15.99 × y = $125.79 + $15.99y
Luke paid is equal or lesser than how much Bella paid, then
99.95 + 19.99x ≤ 125.79 + 15.99y
