Answer:
{x,y} = {-2,2}
Step-by-step explanation:
Solve equation [2] for the variable y
7y = 7x + 28
y = x + 4
Plug this in for variable y in equation [1]
-8x + 4•(x +4) = 24
-4x = 8
Solve equation [1] for the variable x
4x = - 8
x = - 2
By now we know this much :
x = -2
y = x+4
Use the x value to solve for y
y = (-2)+4 = 2
Solution :
{x,y} = {-2,2}
and this intersects at only one point so your answer is A
.25(16x + 12) + 2x = 33
The first step is to distribute the .25 to what's inside the parentheses!
((16x*.25) +(12*.25)) + 2x = 33
Simplify...
4x + 3 +2x = 33
Add like terms...
6x + 3 = 33
Subtract three from both sides
6x + 3 - 3 = 33 - 3
Simplify
6x = 30
Divide each side by six
6x/6 = 30/6
Simplify
x = 5
That's your answer; x = 5! Hope this helped :)
C is your answer because you count 1 square a block
Answer:
F(x) = - 2/5x - 11
Step-by-step explanation:
F(x) = - 2/5x + c
-9 = - 2/5(-5) + c
-9 = 2 + c
- 11= c
F(x) = - 2/5x - 11
