Answer:

Correct option: c) infinitely many solutions

Step-by-step explanation:

We have an equation with two variables, so as we have a system with less equations (just one) than variables (two), we have an infinite number of solutions.

To find some solutions, we can choose values for x and then just calculate the value of y:

x = 0:

-11y = 10 -> y = -10/11

x = 1:

3 - 11y = 10 -> y = -7/11

x = 2:

6 - 11y = 10 -> y = -4/11

And so on.

So the correct option is c): infinitely many solutions

Answer:

11 invitations each

0.25x = 2.75

x = 2.75/0.25

x= 11 invitations

F(x) = -5x +8(7-x) find x such that f(x) =160
s344n2d4d5 [400]

Answer:

Step-by-step explanation:

f(x) = -5x + 8(7 - x)......when f(x) = 160

160 = -5x + 8(7 - x)

160 = -5x + 56 - 8x

160 - 56 = -5x - 8x

104 = - 13x

-104/13 = x

-8 = x <====
