Is (0, 0) a solution to the equation y = 9x?

Answers

(0, 0) is a solution to the equation y = 9x

Given the equation y = 9x, we are to determine whether (0, 0) is a solution to the equation

To do that, we will substitute x = 0 into the expression and determine if the value of y is 0.

If x = 0

y = 9x

y = 9(0)

y = 0

Since the resulting value of y is zero, hence (0, 0) is a solution to the equation y = 9x

H. p = 13c + 75
100
J. c = 13p + 75

Answers

Answer:

The answer is j

Step-by-step explanation:

The equations shows the relationship between c and p is p= 13c + 75.

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

We have table which shows amount that a catering company charges based on the number of people at an event.

So, the equation that can framed from the table as

(y- 400)= (725- 400) / (50-25)  . (x-25)

y- 400 = (325/ 25) (x-25)

y-400 = 13(x-25)

y-400 = 13x - 325

y = 13x - 325 + 400

y= 13x + 75

or p = 13c+ 75

Answers

Answer:

632 square feet

Step-by-step explanation:

Surface area of the prism = 2(lw+wh+lh)

L is the length = 12feet

w is the width = 8feet

h is the height = 11feet

Substitute

S = 2(12*8 + 12*11 + 8*11)

S = 2(96+132+88)

S = 2(316)

S = 632 square feet

Hence the surface are of the prism is  632 square feet

Answers

Answer:

the second one

Step-by-step explanation:

Hello There!

The area of a triangle can be found using this formula

[tex]A = \frac{1}{2} (a+b)h[/tex]

where a and b = bases and h = height

The trapezoid shown has the following dimensions

top base = 9cm

bottom base = 14 cm

height = 12 cm

slant height = 13 cm

using this information, we plug in the values into the formula

So [tex]A = \frac{1}{2} (9+14)12[/tex]

the equation we created matches the 2nd equation therefore the second one is your answer

the second one is right
