Evaluate the expression -2b+x when b=3 and x=-4

-10 is the answer

Step-by-step explanation:

first things that you will replace each number in:

-2x3+(-4)=-10

the answer to the question is -10

Step-by-step explanation:

substitute the given into the question

-2(3)+(-4)

then open the parentheses/multiply

-6-4

then subtract them

-10

50- 250 is correct i did that one too

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
