Use the formula to convert 104 fahrenheit into celsius 9/5c + 32=f?me

Hello from MrBillDoesMath!

104 F = 40 C

Discussion:

9/5C + 32 = F              => in our case, F = 104

9/5C + 32 = 104          => subtract 32 from both sides

9/5C         = 104 - 32   =>

9/5C  = 72                   => multiply both sides by 5/9 (the reciprocal of 9/5)

(5/9)*(9/5) C = 72 * (5/9) =>

C = 72*5/9 = 360/9 = 40

Thank you,

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
