Answer:90cents

Cost of a  10 minute call before 10pm:

37 cents + 9cents*7minutes = 37 cents+63 cents =100 cents

10% of 100cents:

100*10/100= 10 cents

Cost of  the call after 10 pm (i.e with a 10% discount)

100-10= 90 cents

Answer:

  $0.90

Step-by-step explanation:

A 10-minute call exceeds the 3-minute initial period by 7 minutes. The initial period charge is 37¢. The additional minute charge is 7·9¢ = 63¢. Then the regular charge for that call is ...

  37¢ +63¢ = 100¢ = $1.00

The 10% discount reduces the charge by ...

  10% × $1.00 = $0.10

so the final cost of the 10-minute call is ...

  $1.00 -0.10 = $0.90 . . . . . cost of the call

F(-4)=8 and f(-1)=4 write the linear equation
kobusy [5.1K]

f(-4)=8\to(-4,\ 8)\\\\f(-1)=4\to(-1,\ 4)

The point-slope formula of a line:

y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

Substitute:

m=\dfrac{4-8}{-1-(-4)}=\dfrac{-4}{3}=-\dfrac{4}{3}\\\\y-8=-\dfrac{4}{3}(x-(-4))\\\\y-8=-\dfrac{4}{3}x-\dfrac{16}{3}\ \ \ \ |+8\\\\y=-\dfrac{4}{3}x-\dfrac{16}{3}+\dfrac{24}{3}\\\\y=-\dfrac{4}{3}x+\dfrac{8}{3}\ \ \ |\cdot3\\\\3y=-4x+8\ \ \ |+4x\\\\4x+3y=8

The slope-intercept form: y=-\dfrac{4}{3}x+\dfrac{8}{3}

The standard form: 4x+3y=8
