Answer:
m = -7
initial value = 27
Step-by-step explanation:
The rate of change is also known as the slope of a line.
To find this do y1-y2/x1-x2 or y2-y1/x2-x1. You can't do rise/run in this case because there is no graph. I will help you with both answers for the first question only, because I think it is better for you to also practice.
The initial value is also when x = 0, therefore the initial value is 27.
The slop is:
27-(-8)/0-5
35/-5
-7
The rate of change, or slope, for the first question is -7.
First rewrite the mixed number as an improper fraction:
-1 1/14 = -15/14
Now you have :
-3/7 / -15/14
When dividing by a fraction, flip the second fraction over and change divide to multiply:
-3/7 x -14/15
Now multiply top by top and bottom by bottom:
(-3 x -14) / ( 7 x 15) = 42/105
Simplify by diving each number by 21 to get the final answer :
2/5
Answer:
a.) y= 25 + 5x
b.) 45$
Step-by-step explanation:
25$ from the start and adds 5 for extra
y= 25+5(4)
y=25+20
y=45$
