Answer:
x =5
Step-by-step explanation:
2(5x – 2) – 2x– 2 = 34
Distribute
10x-4-2x-2 = 34
Combine like terms
8x -6 = 34
Add 6 to each side
8x-6+6 = 34+6
8x = 40
Divide by 8
8x/8 = 40/8
x =5
Answer: x=-3/4
Step-by-step explanation:
Since we know f(x)=6, we can set it equal to the equation.
6=9+4x [subtract 9 on both sides]
-3=4x [divide both sides by 4]
x=-3/4
Answer: He must save for 11 or more weeks.
Step-by-step explanation:
Using the inequality, we will solve for x to determine the number.
130 + 20x > 350 Subtract 130 from both sides
-130 -130
20x > 220
x> 11
Since x is greater than 11, it means that if he saves for 11 weeks, then he will save the exact amount of $350, but since he wants to save more, he must save for 11 or more weeks.
Answer: m = 0
Step-by-step explanation: To find the slope of the line, we can use the graphing method. To do this, we start by plotting our two points.
Let's label (6, 1) as point A and (-6, 1) as point B.
Now, graph our line through the 2 points.
Now remember that the slope, or m, is equal to
the rise over run from point A to point B.
To get from point A to point B, we rise o units and run -12 units.
So our slope or rise / run is 0/-12 which simplifies to 0.
This should make sense because we have a horizontal or flat line and
remember that the slope of any horizontal or flat line is 0.
