PLEASEEE HELP ME!!! I NEED THE ANWER ASAP!!!
Artist 52 [7]

Answer:

y = 3x + 30

Step-by-step explanation:

This is what the table should look like.

Number of Bars Sold (x)           Total Earnings (dollars) (y)

0                                                 30

1                                                  33

2                                                 36

3                                                 39

When x = 0, y = 30. The point (0, 30) is the y-intercept.

As x goes up by 1, from 0 to 1, from 1 to 2, from 2 to 3, y goes up by 3, from 30 to 33, from 33 to 36, from 36 to 39.

A change of 1 in x results in a change of 3 in y.

That is a slope of 3 since

slope = (change in y)/(change in x)

The equation of a line in slope-intercept form is

y = mx + b

We have m = 3 and b = 30, so the equation is

y = 3x + 30

Answer: 3x + 30

Of the three different types of horses on a ranch, 1/4 are Arabians, 2/5 are Thoroughbreds, and the rest are Morgan's. What frac
mars1129 [50]

Answer:

The fraction of horses that are Morgan's=17/20

Step-by-step explanation:

Step 1: Determine fraction for each breed

Arabians=1/4

Thoroughbreds=2/5

Morgan's=unknown

Step 2: Express each breed as a fraction of the total

Number of Arabians=fraction of Arabians×total number of horses

Let total number of horses be x

Arabians=(1/4)×x=1/4 x

Thoroughbreds=(2/5)×x=2/5 x

Morgans's=m

Step 3: Calculate fraction of Morgans

Total number of horses=Arabians+Thoroughbreds+Morgans

x=(1/4)x+(2/5)x+m

solve for m;

m=x-(1/4)x-(2/5)x

m=x-3/20x

m=17/20 x

The fraction of horses that are Morgan's=17/20
