Answer:

(-1, 0), (0, 8), (1, 16), (2, 24), (3, 32)

Step-by-step explanation:

To find answers to problems like these, take the x-value, which in this case is -1, and replace it with the variable,

y = 8*-1 + 8. Then do the rest, y = -8 + 8, y = 0. You already have the x, -1, and now you got y, 0. Then pit in ordered pairs, x first, then y, (-1, 0)

The perimeter of a triangle is 7272 cm. the longest side is 66 cm less than the sum of the other two sides. twice the shortest s

VashaNatasha [74]

Suppose the three sides are a, b, and c, with c being the longest, a being the shortest
first equation: c=(a+b)-66
second equation: 2a=c-55=> c=2a+55
plug c=2a+55 into the first equation: 2a+55= a+b-66 => b=a+121
a+b+c=a+(a+121)+(2a+55)=7272 =>4a+176=7272 =>a=1774
a=1774, b=1895, c=3603

You use a garden hose to fill a wading pool. If the water level rises 11 centimeters every 6 minutes and you record the data poi

Answer:

$y=22\ cm$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x -----> the number of minutes

y ----> the water level in centimeters

In this problem we have a proportional relationship between the variables x and y

Find the value of k

For x=6 min, y=11 cm

$k=11/6$ -----> the slope is equal to the constant of proportionality k

The linear equation is

$y=(11/6)x$

For (12,y)

we have

x=12 min

substitute in the equation and solve for y

$y=(11/6)12$

$y=22\ cm$

Find the difference and write it in simplest form 7 3/8 - 2 7/9

Papessa [141]

Well first you have to turn the mixed number into a improper fraction.
7 2/8=59 over 8
2 7/9=25 over 9
Then u would multiply the 59 by 9 and 8 by 9 and u should get 531 over 72 and for the second fraction u should multiply the 25 by 8 and the 9 by 8 and you should get 200 over 72 as a improper fraction.
Then you have to subtract 531 over 72 by 200 over 72 and u should get 231 over 72 which is 4 and 43 over 72 when simplified.
The answer: 4 43/72
Hope this helps!!!!
