Y=2x+9 y=4x-9 Solve the system of equations.
Deffense [45]

Answer:

Your solution is (9, 27) or x = 9, y = 27

Step-by-step explanation:

y = 2x + 9

y = 4x - 9

We can see that both of these equations equal y, so we can set them equal to each other.

2x + 9 = 4x - 9

Add 9 to both sides.

2x + 18 = 4x

Subtract 2x from both sides.

18 = 2x

Divide both sides by 2.

9 = x

Now we want to find y. To do this, plug x = 9 back into one of the original equations.

y = 2(9) + 9

Multiply.

y = 18 + 9

Add.

y = 27

Your solution is (9, 27)

Check your answer by plugging x = 9 and y = 27 back into the original equations.

y = 2x + 9

27 = 2(9) + 9

27 = 18 + 9

27 = 27

y = 4x - 9

27 = 4(9) - 9

27 = 36 - 9

27 = 27

Your answer is correct.

Hope this helps!

Which of these is a algebraic expression for five times the sum of two And Y?
andre [41]

Hey there!

The correct choice is D. 5(2 + y)

As you can see, the expression matches the description

5 times = 5( The parentheses directly next to the 5 means to multiply what is inside the parentheses by that number, in this case, 5

The sum of 2 and y = (2 + y)

Therefore, that makes D the CORRECT option

Hope this helps you!

God bless ❤️

What is the equation of the line with a y-intercept of 4 and a point (8,8)? ​
Nookie1986 [14]

Answer:

The equation of the line with a y-intercept of 4 and a point (8,8) is y=\frac{1}{2} *x+4

Step-by-step explanation:

A linear equation can be expressed in the form

y = m * x + b

where x and y are coordinates of a point, m is the slope and b is the y-intercept. Since this equation describes a line in terms of its slope and its y-intercept, this equation is said to be in its slope-intercept form.

Graphically this equation represents a line.

In this case, you know:

  • The point (x,y)=(8,8)
  • Y-intercept= 4

Replacing:

8=m*8 +4

Solving:

8-4=m*8

4=m*8

4÷8= m

m=\frac{1}{2}

Then, <u><em>the equation of the line with a y-intercept of 4 and a point (8,8) is </em></u>y=\frac{1}{2} *x+4<u><em></em></u>
