X=5+y
x+y=-15

subsitute 5+y for x

5+y+y=-15
5+2y=-15
minus 5 from both sides
2y=-20
divide both sides by 2
y=-10

sub back
x=5+y
x=5-10
x=-5

the numbers are -10 and -5

The net of a triangular prism is shown. Use the ruler provided to measure the dimensions of the net to the nearest half centimet
Black_prince [1.1K]

If the area of the triangle and the rectangle is 4 square cm and 2 square cm. Then the total surface area of the triangular prism will be 14 square cm.

<h3>What is a triangular prism?</h3>

A closed solid with two parallel triangular bases joined by a rectangle surface is known as a triangular prism.

The total surface area of the triangular prism will be

Total surface area = 2(area of the triangle) + 3(area of the rectangle)

The area of the rectangle will be

Rectangle area = 2 x 1

Rectangle area = 2 square cm

The area of the triangle will be

Triangle area = 0.5 x 4 x 2

Triangle area = 4 square cm

Then the total surface area will be

Total surface area = 2 x 4 + 3 x 2

Total surface area = 8 + 6

Total surface area = 14 square cm

More about the triangular prism link is given below.

A graph of a quadratic function is shown below. graph of y equals negative 2 times x squared plus 40 x plus 600 Which of the fol
Leno4ka [110]

Answer:

Option c. (0,800)

Step-by-step explanation:

The options for your question are attached in th epicture below

The function represented in the graph is

y = -2*x^2 + 40*x + 600

We just need to verify if each ordered pair belongs to the function

a. (-10,0)

y = -2*(-10)^2 + 40*(-10) + 600

y = 0

It is an intercept

b. (0,600)

y = -2*(0)^2 + 40*(0) + 600

y = 600

It is an intercept

c. (0, 800)

y = -2*(0)^2 + 40*(0) + 600

y = 600  ≠ 800

It is not an intercept
