Answer:

r = 1

Step-by-step explanation:

slope = change in y / change in x, so:

change in y / change in x  = 2/3

5 - r / 7 - 1 = 2/3

5 - r / 6 = 2/3

\frac{5-r}{6}=\frac{2}{3}

now solve this equation.

first, multiply both sides by 6 to get rid of the fraction:

5 - r = 4

subtract 5 from both sides

-r=-1

multiply both sides by -1

r=1

The news listed that the al?rage price Of a gallon Of gasoline
Virty [35]

Answer:

b. between $3.04 and $3.36

Step-by-step explanation:

Given,

Price of 1 gallon of gasoline = $3.20

Margin of Error = 5%

We have to find out average cost of gallon of gasoline.

For this, we have to find out 5% of the price of gasoline. Which is calculated by dividing 5 by 100 and then multiply it by 3.20.

Amount of margin of error = \frac{5}{100}\times3.20 = 0.16

Hence The margin of error is ±, So we will subtract the amount of margin of error with actual amount of 1 gallon of gasoline. Also we will add the amount of margin of error with actual amount of 1 gallon of gasoline.

Margin of error 1 = 3.20-0.16= \$3.04

Margin of error 2 = 3.20+0.16= \$3.36

Hence the Average cost of a gallon of gasoline should be between $3.04 and $3.36.

Given the speeds of each runner below, determine who runs the fastest. \text{Katie runs 10 feet per second.} Katie runs 10 feet
Mrrafil [7]

Answer:

noah

Step-by-step explanation:

katie = 10 f/s

ron = 466 f/33s

noah = 559 f/60s

katie = 10 f/s

ron = 466/33 = 14.1212...f/s

noah = 559/60 = 9.3166...f/s

noah is the fastest

Can someone answer the 2 questions in the picture i really need help
Radda [10]
Hi.

The first question is a direct variation — specifically y = 1.8x

In the second one (if my calculations are correct), it's not a direction variation.

Hope this helps :)

Calculations:

y = 1.8(3) = 5.4

y does not equal x, 2x, or -2x.
