Answer:

(x, y) = (-10/7, 92/7)

Step-by-step explanation:

12x + y = -4

y = 2x +16.

Substituting the value of y ( second equation ) into the first equation, we get:

12x + (2x + 16) = -4

14x + 16 = -4

14x = -20

x = -20/14 = -10/7.

Now, to find y, all we have to do is to substitute the value of x into the second eqation. We get:

y = 2 * (-10/7) + 16

y = -20/7 + 16

y = 92/7

IgorLugansk [536]

Answer:

y=0.2x+29

Step-by-step explanation:

Given that:

y is the total monthly of the A Fee and Fee plan.

x is the number of monthly minutes used.

  • If a customer uses 290 minutes, the monthly cost will be $87, we have the pair (290, 87)
  • If the customer uses 980 minutes, the monthly cost will be $225, this is the coordinate pair (980, 225).

We want to obtain an equation in the form: y=mx+b

First, let us determine the slope, m

Given points (290, 87) and (980, 225):

<u>Slope</u>

m=\dfrac{225-87}{980-290} =\dfrac{138}{690}=0.2

Next, we determine the y-intercept, b.

Substituting the pair (290, 87) and m=0.2 in y=mx+b, we obtain

87=0.2(290)+b

b=87-0.2(290)=29

Therefore, our equation in the form y=mx+b is:

y=0.2x+29
