Sorry if I’m being annoying but. Evaluate 4+ (m – n)" when m=7 and n=5.
+) The value of the expression is

20

Step-by-step explanation:

Substitute these numbers in the expression.

You get-

4+ (7-5)^4

Now use PEMDAS.

Solve the parentheses first.

4+2^4.

Solve 2^4.

4+16

Add.

20.

Hope this helps! :)

when studying polynomials, you often hear the terms zeros, roots, factors and x x the multiplicity of a zero is important because it tells us how the graph of the let's look at the graph of a function that has the same zeros

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
