If y varies directly with x:

y = k * x

When x = 2, y = - 10.

- 10 = k * 2

k = - 10 : 2

k = - 5

Therefore: y = - 5 x

And when x = 12 ;

y = - 5 * 12

Answer:

y = - 60

y=kx y=-5x

-10/2=k 2/2 y=-5(12)

-5=k y=-60

Bingel [31]

Answer:

y=14x+56

Step-by-step explanation:

Question says to find the equation in slope intercept form that means we have to use y=mx+b form.

Where b is the initial value or you can say y-value when x=0

Given that at shift x=0, number of people y=56

so that means b=56

now find the difference between consecuitve value of y

70-56=14

84-70=14

98-84=14

We are getting constant difference of 14 so that mean slope m=14

now plug values of m and b into y=mx+b

Then final answer will be y=14x+56

horrorfan [7]

Answer:

13x + 10x + 21 = 90 \\ 23x + 21 = 90 \\ 23x = 69 \\ x = 3

The measure of angle DEH

13(3) = 39 \: degrees

commercial angle FEH

10(3) + 21 =  \\ 30 + 21 = 51 \: degrees
