Answer:
c
Step-by-step explanation:
C. This is the correct answer because the wage rises by $2, which is 2/20=10% increase. Next year the increase percent is 2.20/22=10%. That's a constant percent increase
0.5(2x+2)=-4
Multiply by 2 on both sides
2x+2=-8
Subtract 2 on both sides
2x=-10
Divide by 2 on both sides
x=-5
Answer:

Step-by-step explanation:
yes
To solve this problem, you need to set up a proportion. If she jogs 6 miles per hour, then this can be written as . If there are 5280 feet in a single mile, then first we multiply the two proportions like this:
The two 'mile' values cancel each other out, so then just multiply . This equals to 31680 feet per hour. Now let's convert to seconds.
, or 360 seconds every hour. Since hours are much longer than seconds, multiply 31680 by the reciprocal of 360, so that it makes sense.
She runs 88 feet per second.
Answer:
y = 4x - 7
Step-by-step explanation:
y = mx + b where m = slope and b = y-intercept
In this case m = 4 and y-intercept b = -7
Equation
y = 4x - 7
