Evaluate the function when x = -5.
f(x) = 2x + 7

Step-by-step explanation:

Replace x with -5

2(-5)+7

-10+7

-3

-3

Step-by-step explanation:

Evaluate 2 x + 7 where x = -5:

2 x + 7 = 7 - 5×2

Hint: | Multiply 2 and -5 together.

2 (-5) = -10:

-10 + 7

Hint: | Subtract 10 from 7.

7 - 10 = -3:

-3

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

27 +27 or 27times 2=54

the diffrence is 0
