I’m going to try my best so I apologize if this is incorrect

function: f(3) = 15x- 40
solution: 5
15 • 3 = 45
45 - 40 = 5

function: f(21) = 2/3x + 20
solution: 34
2/3 • 21 = 14
14 + 20 = 33

function: f(-2) = (3x)^2 + 17
solution: 53
[3(-2)]^2 = 36
36 + 17 = 53

again I apologize if this is incorrect

The product of 4 and the sum of a number x and 8
Nesterboy [21]

Answer:

8(x+3)

Explanation:

"The product of 8 and" means 8 is going to be multiplied times another quantity. "...the sum of a number x and 3" means that 8 is going to be multiplied times (x+3).

This is represented by 8×(x+3), which simplifies to 8(x+3).

Solve the System of equations x = -2 ; y= -3 .(show your work step by step).
steposvetlana [31]

Answer:

Determine the point of intersection by using substitution and solving for the variables.

Explanation:

Solving a system of equations imply we find the point of interception.

To do this, we must use substitution to find one variable, and use that value to determine the exact value of the other.

Here, we'll isolate

x

.

−

2

x

−

2

y

=

−

4

−

2

x

=

2

y

−

4

x

=

−

y

+

2

Now that we have our variable expression, we can sub this into the other equation and solve for

y

.

2

x

+

3

y

=

9

(

−

y

+

)

y

=

−

2

y

+

4

+

3

y

=

9

4

+

y

=

9

y

=

5

Now that we know our

y

value, we can sub it into any equation to solve for

x

.

x

=

−

y

+

2

x

=

−

(

5

)

+

2

x

=

−

5

+

2

x

=

~

3

Thus, our point of intersection is

(

~

3

,

5

)

.

If we graph the two equations, we can see the point of intersection is in fact

(

~

3

,

5

)

.

graph{(-2x-2y+4)(2x+3y-9)=0 [-8.875, 11.125, -0.36, 9.64]}

Hope this helps :)
