Please help with math problem !! (explanation needed) -3 + (8 – 2x)4 = 29

x = -4

Step-by-step explanation:

To solve this type of question, put the term with the exponent on one side and the numerical term on the other side

∵ -3 + = 29

→ Add 3 to both sides

∵ -3 + 3 + = 29 + 3

∴ = 32

→ Remember is = a, then x = , that means to move the exponent

   from one side to the other side reciprocal it

∴ 8 - 2x =

→ Use your calculator to find the value of  

∵   = 16

∴ 8 - 2x = 16

→ Subtract 8 from both sides

∴ 8 - 8 - 2x = 16 - 8

∴ -2x = 8

→ Divide both sides by -2

∴ x = -4

To check the solution substitute x by -4 in the left side and find its answer if it equals the right side, then the solution is right

∵ Left side ⇒ -3 + (8 - 2 × -4) = -3 + (8 + 8) =-3 + (16)  = -3 + 32 = 29

∵ Right side = 29

∴ The solution is right

correct answer:

b.(19,-2)

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)
