Answer:

<h2>2 and 7 are alternate exterior angles</h2>

Step-by-step explanation:

Alternate exterior angles are angles that are on different sides of the transversal and on the outside of the parallel lines. There is a theorem that says that alternate exterior angles are congruent if two parallel lines are cut by a transversal.

If a triangle with vertices A(-1, 4), B(-1, -2), C(2, -2) is dilated with a scale factor of 2 and a center of dilation at the or

givi [52]

Answer:

A' (-2,8) B' (-2,-4) C' (4,-4)

Step-by-step explanation:

Dilations Rule :

(x,y) → (kx,ky)

Scale factor = K

When your scale factor is more than one our triangle gets bigger. When your scale factor is less than one our triangle gets smaller.

( you plug in 2 in every point and those are your answers).

Remember negative times negative is positive and positive times negative is negative.

X/-9 =3<br>I dont understand this.

STatiana [176]

Final Answer: $x = -27$

Steps/Equations:

Question: $\frac{x}{-9} = 3$

Step 1: Move the negative sign to the left side.

$-\frac{x}{9} = 3$

Step 2: Multiply both sides by $3$ .

$-x = 3 * 9$

Step 3: Simplify $3 * 9$ to $27$ .

$-x = 27$

Step 4: Multiply both sides by $-1$ .

$x = -27$

Please help me make a word problem for water bottles. (See picture below)

Alona [7]

1. "Kevin has a 15% off coupon for buying water bottles at Walmart.

One water bottle is usually $2.00. How much did Kevin pay with his coupon?"

2. $1.70.

3. The answer is $1.70, because $2.00 * 0.15 = 30 cents, which is how much the coupon is worth. The sale price is the original amount minus the coupon's monetary value (which is $2.00 - $0.30 = $1.70).

4. I'll leave that part to you lol
