The first thing we are going to do for this case is to rewrite the function correctly.
We have then:
For power properties we have:
Canceling similar terms we have:
Doing the calculations we have:
Answer:
The result of the expression is:
A 972
Answer:
Step-by-step explanation:
4 (x + 3) = 2x + 8 <----"four times the sum of a number and three is equal to eight more than twice the number."
Second, we want to solve the equation:
4 (x + 3) = 2x + 8
4x + 12 = 2x + 8
2x + 12 = 8 <-------subtract 2x from both sides of the equation.
2x = -4 <-------subtract -12 from both sides
x = -2 <-------divide both sides by 2 which leaves a negative answer
Third, we want to check the answer by substituting the value of -2 for x in the original equation.
4 (x + 3) = 2x + 8
4 (-2 +3) = 2(-2) + 8
-8 + 12 = -4 + 8
4 = 4
4 (x + 3) = 2x + 8 <----"four times the sum of a number and three is equal to eight more than twice the number."

4 = 4
2.56 times 0.03 is 0.0768 then round to hundredth is 0.08 i think
Plot y = -3x-3 (x = 0, y - -3, and x =1, y = - 6 ), as a *dashed* line (> means greater, not greater or equal than), then shade everything on top of that line.
Plot y = 4x+4 (x=0, y = 4, x = 1, y = 8) again as a dashed line, and shade everything above it.
Where both shades are on op of each other, both inequalities hold. This is the answer. Good luck plotting!
