Answer:

a. ZWY

b. 9cm

c. Aly's solution is correct

Step-by-step explanation:

a. YW bisects the whole angle, thus angle XWY and angle ZWY are same

NOTE: REMEMBER TO WRITE THE LETTER ACCORDINGLY

b. the two triangles are congruent by AAS (angle-angle-side) thus the two legs of the the triangles are also congruent. when one is 9cm, the other is also 9cm.

c. Since the triangles are congruent, their sides also congruent.

 7x-20=2x-5

 7x-2x=-5+20

     5x=15

       x=3

This is same as Aly's solution

1.dilate by 3/5 : (20,10)
inysia [295]

Answer:

a) )12,6)

b) (12,2)

c) (4,-7)

d) (9,-7)

Step-by-step explanation:

a) Dilation

When we dilate, we multiply the given scale factor by each of the coordinates

We have this as follows;

(20 * 3/5, 10 * 3/5) = (12, 6)

2. Here, we will add 5 to the x-axis value and subtract 6 from the y-axis value

We have this as;

(7+ 5, 8-6) = (12,2)

3. By reflecting across the x-axis

we have (x,y) changing to (x,-y)

so we have ;

(4,7) becomes (4,-7)

4. Rotation by 270 degrees (7,9)

If clockwise;

(x,y) becomes (y,-x)

so we have

(7,9) becoming (9,-7)

Tyrell has a bankruptcy on his credit report and therefore pays higher interest rates on his current loans. he calculates that t
vova2212 [387]

Based on the simple interest amount he could be making, and the rate of investment, Tyrell's additional interest per month is $1,000.

<h3>How much is Tyrell paying in additional interest?</h3>

Assuming the additional interest that Tyrell is paying is x, the following formula can be used:

300 = (x × 2.5%) x 12 months

Solving gives:

300 = 0.025x × 12

0.025x = 300/12

x = 25 / 0.025

x = $1,000
