6x - 2 = 5x - 7 - 3x

Answers

6x-2=5x-7-3x
-3x
6x-2=2x-7
+2 +2
6x= 2x-5
-2x -2x
4x = -5
/4 /4
X=-5/4
6x - 2 = 5x - 7 - 3x
6x - 2 = 2x - 7
6x - 2x = -7 + 2
4x = -5
x = - (5)/(4) or x = -1 (1)/(4)

Suzanne needs material for her school project. She buys 4.75 yards of material at $5.37 a yard. What is the total cost of the material? Round to the nearest cent.

Answers

Answer:

$25.51

Step-by-step explanation:

To find the total cost, we need to multiply the amount per yard by the amount of yards of material used.

We have 4.75 yards of material and it costs 5.37 for every yard. All we have to do now is multiply them together.

5.37*4.75=25.51 rounded up.

Hope this helps!

A graph is constructed such that time (in seconds) is the x-variable and distance (in kilometers) is the y-variable. If you plot the distance that light travels at a speed of 300,000 kilometers, what is the slope of the graph?

Answers

The slope would be
y=(1/60)x
y=mx+b
m=1/60 b=0    :D
The answer is 300,000

If the graph of the function g defined by g(x)=-2x^2+9. Is translated vertically downward by 8 units, it becomes the graph of a function f. Find the expression for f(x)

Answers

g ( x ) = - 2 x² + 9
If this function is translated vertically downward by 8 units it becomes:
f ( x ) = g ( x ) - 8
f ( x ) = - 2 x² + 9 - 8
Answer:
f ( x ) = - 2 x² + 1
  

Based on the graph above, what is the solution to this system.

Answers

I would say infinitely many solutions because parallel lines never touch, and it isn't a case of having no slope because if it had no slope then it would be no solution. So it's D.
There is no solution because they're parallel
