Solve the following equation: 96= -6( -4-3y)<br> a. y=2<br> b.y=4<br> c.y= -2<br> d. y=6
tankabanditka [31]
               96 = -6 * (-4 - 3y) <== It's easiest to solve when the y is on the right
                    ↓
-6 * (-4 - 3y) = 96                <== Multiply the -6 by everything inside the
                                           parentheses
                    <span>↓</span>
     24 + 18y = 96                <== Subtract the 24 from both sides
                    ↓
             18y = 72                <== Divide both sides by 18
                    ↓
                 y = 4 

The correct answer is choice B. y = 4.
Hope that helped =)

natka813 [3]

Answer:

Poster’s perimeter = 150 in

Step-by-step explanation:

Given:

Width of poster = 2.5 ft = 2.5 × 12 = 30 in

Find:

Poster’s perimeter.

Computation:

Height of poster = [30×6]/4

Height of poster = 45 in

Poster’s perimeter = 2 [Width of poster + Height of poster]

Poster’s perimeter = 2 [30+45]

Poster’s perimeter = 2 [75]

Poster’s perimeter = 150 in

Triangles T1 and T2 are congruent.
Inessa [10]

The single transformation that can be used to map T₁ onto T₂ is Rotate T₁ 180° about the origin.

<h3>What transformation would map T₁ onto T₂?</h3>

When a shape is rotated 180° about the origin, it means that the points go from (x, y) to (-x, -y).

The points on T₁ if rotated 180° about the origin would go from:
(-2, -2) to (2, 2)

(5, -6) to (-5, 6)

(5,0) to (-5, 0)

These are the points of T₂ so the way to map T₁ on T₂ is to use a 180° about the origin.
