<span>y+4=2/3(x+7)

</span><span>Multiplying both sides by the denominator which is 3:
</span>3(y+4) = 3(2/3) * (x+7)
3y+12=2x+14

Subtract 3y:
12 = 2x - 3y + 14

Subtract 14
-2 = 2x - 3y

This is 15 points for whoever answers.

zalisa [80]

Answer:

Y = 40

Step-by-step explanation:

First, find the slope-intercept of the table

Slope-intercept form: y = mx + b

$m=\frac{y_2-y_1}{x_2-x_1}$

(3, 1) and (6,2)

$m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{2-1}{6-3}\\\\m=\frac{1}{3}$

$y=mx+b$

$y=\frac{1}{3}x+b$

Find b using (6,2):

$y=\frac{1}{3}x+b\\\\2=\frac{1}{3}(6)+b\\\\2=\frac{6}{3}+b\\\\2=2+b\\\\-2\ -2\\\\0=b$

$y=\frac{1}{3}x+b== > y=\frac{1}{3}x+0== > y=\frac{1}{3}x$

$y=\frac{1}{3}x$

What will be the value of Y when X = 120?

Substitute 120 for x into $y=\frac{1}{3}x$

$y=\frac{1}{3}x\\\\y=\frac{1}{3}(120)\\\\y=\frac{120}{3}\\\\y=40$

(120, 40)

Therefore, when X = 120, Y = 40

Hope this helps!

Riley and Erik have earned a total of 135 tokens to buy items in the school store. The ratio of the number of tokens that Riley

inysia [295]

There are 72 tokens with Riley and 63 tokens with Erik

<em><u>Solution:</u></em>

Riley and Erik have earned a total of 135 tokens to buy items in the school store

Total number of tokens = 135

The ratio of the number of tokens that Riley had to the number of tokens that Erik has is 8 to 7

Number of tokens with Riley : Number of tokens with Erik = 8 : 7

Let the number of tokens with Riley be 8x

Let the number of tokens with Erik be 7x

Since, Total number of tokens = 135

number of tokens with Riley + number of tokens with Erik = 135

8x + 7x = 135

15x = 135

x = 9

Therefore,

Number of tokens with Riley = 8x = 8(9) = 72

Number of tokens with Erik = 7x = 7(9) = 63

Thus there are 72 tokens with Riley and 63 tokens with Erik
