Y = mx + b....(5,6)
slope(m) = 5
now we sub
6 = 5(5) + b
6 = 25 + b
6 - 25 = b
- 19 = b
so ur equation is : y = 5x - 19...now we sub in 21 for x
y = 5(21) - 19
y = 105 - 19
y = 86
so when x = 21, y = 86
Answer:
Step-by-step explanation:
so you wanna first add the hours
12
then add the number of trees painted in that number of hours
26
do 198 divided by 26
7.62( rounded to the nearest hundredth)
then take that product and multiply it by 12
91( rounded to the nearest one)
tha'ts your answer: 91 days
6
I would round:
1.78 to 2
4.25 to 4
So: 4+2=6
Answer:
Proportional relationships are relationships between two variables where their ratios are equivalent.
Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".
I really recommend watching Khan Academy's video over proportional relationships, the speaker explains it very well!!
