Which expression is equivalent to 13c + 9f - 7f + 3c + 15 - 2

Expression 1: 16e + 2f + 13
Expression 2: 28e + 2f + 1
Expression 3: 22e + 8f + 1
Expression 4: 6e + 12f + 13

Sorry but none where c there e but no c .

But it would be 16c +2f +13 .

Step-by-step explanation:you need to combine like terms

which are 13c +3c =16c and 9f- 7f=2f and 15-2 =13 .

Hope it helps .

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
