2x -4(x+2) = -2x - 8

Mathematics
1 answer:
azamat3 years ago
6 0

Answer:

All real numbers

Step-by-step explanation:

First, distribute the -4 on the left side

2x-4(x+2)=-2x-8

2x-4*x+-4*2=-2x-8

2x-4x-8= -2x-8

Combine like terms on the left side

-2x -8 = -2x -8

Since the two sides are equal, all real numbers are solutions

Hope this helps! :)

Explain how to rewrite the function shown in order to determine the transformation of the parent function. Then, describe the tr
fredd [130]

The <em><u>correct answer</u></em> is:

Compared to the parent graph, this graph is compressed horizontally, reflected across the y-axis, and shifted right 4 units.

Explanation:

The parent function in this situation is y=\sqrt[3]{x}.

Algebraically, the changes we can see from the parent function to this function is that the variable is multiplied by 8, negated, and had 4 subtracted from it.

When we negate the variable, this reflects the graph across the y-axis.

When we multiply the variable by a number greater than 1, this horizontally compresses the graph.

When we subtract a number from the variable before taking the cubed root, this shifts the graph horizontally; specifically, it shifts it to the right.

Thus the graph will be reflected across the y-axis, horizontally compressed by 1/8, and shifted 4 units to the right.

Write the equation of the line that passes through the point(-6,12) and is parallel to the line y=8
Ugo [173]

Answer:

y = 12

Step-by-step explanation:

y = 8 is the equation of a horizontal line, parallel to the x- axis.

Thus a parallel line will also be horizontal.

The equation of a horizontal line is

y = c

where c is the y- coordinates of the points it passes through.

The line passes through (- 6, 12) with y- coordinate of 12, thus

y = 12 ← equation of parallel line

DerKrebs [107]

Answer:

  80 ft²

Step-by-step explanation:

The carpet area will be the area of the pentagon less the 25 square feet taken up by the tree. The area of the pentagon is found by putting the given numbers into the given formula.

  pentagon area = 5((7 ft)(6 ft))/2 = 105 ft²

  carpet area = 105 ft² -25 ft² = 80 ft²

Peter will need 80 square feet of carpet.

If P(x) = ax 3 + bx - 3 and P(-1)-0, then the value of P(1) is:
sergey [27]

Answer:

(a) -6

Step-by-step explanation:

P(x) = ax^3 +bx - 3

  • P(-1) = -a-b-3 = 0
  • therefore a+b=-3
  • P(1) = a+b-3
  • P(1) = -3 - 3 = -6
  • (a)
