Answer:
y = -2x + 6 and y = 1/3x - 7
Step-by-step explanation:
For A, using rise over run, you can count 2 units up and 1 unit left of any given point to get to the next point. Because left is the negative direction on a graph, the 1 unit is negative. To calculate slope, divide the rise (2) over the run (-1) and substitute the slope as m into y = mx + b. In the formula, b is the y-intercept (where the line crosses the x axis). The y-intercept of A is 6, so replace b in the formula with 6:
y = -2x + 6
The slope of B is 1/3 and the y intercept is -7, so substitute those values into the formula again to get the answer for B:
y = 1/3x - 7
Answer:
E. 750 rounds to 800
Step-by-step explanation: first thing is to look at the tens value, numbers 1-4 get rounded down and numbers 5-9 get rounded up.
Answer:
15 units
Step-by-step explanation:
If one side of a triangle is 5 units you multiply that by 3 (3 sides in a triangle)
= 15 units

Answer:
42 hours
Step-by-step explanation:
Natalie needs to save a total of $479.58
She already saved $149.98
The amount left to save is
= 479.58-149.98
= 329.7
If she earns 7.85 dollars working per hour then the number of hours she can work to get $329.7 can be calculated as follows
= 329.7 / 7.85
= 42
Hence Natalie will work for 42 hours to meet her goals
Answer:
