Answer:
y=x+3
Step-by-step explanation:
y=x would go through (3,3)
adding 3 to the y-int would make it go through (3,6)

A) The vertices of the ABCD square are:
(2,2), (1(4), (3,5), and (4,3).
The reflection over the x-axys keeps the same x-coordinate and changes the y-coordinate ot its negative.So, the vertices of the square A'B'C'D' are:(2,-2), (1,-4), (3,-5), and (4,-3).You can
see the figure attached showing the four vertices.
<span>B. Is AB congruent to A'B'? Explain
Answer: Yes, they are congruent. You can affirm that because
reflections are transformations that do not change either sizes or angles, but keep them, so the two squares are congruent.
C. Is the area of ABCD ≈ area of A'B'C'D'? Explain.
Answer:Yes, the two areas are equal since you have shown that the two figures are congruent.

Answer:
1. a. 2,000
2. b. 10 years
3. a. 6.72937
4. d. 9%
Step-by-step explanation:
1. If 58% are boys, the percentage of girls is:
= 100 - 58
= 42%
That means 840 is 42% of the students in class. The students in class are therefore:
= 840 / 42%
= 2,000 students
2. If Birr 300 is invested at 6% per year, the amount in interest it earns per year is:
= 300 * 6%
= Birr 18
To get to Birr 180, it would take:
= 180/18
= 10 years
3. When a number is in percentage that means that it is a fraction with the denominator being 100. The number is decimal will therefore be it divided by 100:
= 672.937/100
= 6.72937
4. The investment accrued Birr 12 out of Birr 400 in 4 months. This means that it increased by:
= 12/400
= 3%
A year can be divided into three by 4 months. This means that the yearly rate is therefore:
= 3% * 3
= 9%
Answer:
<h2>x = 12</h2>
Step-by-step explanation:
You have to solve this equation:
(8x - 3) + 37 + (5x - 10) = 180
then
13x +37 - 13 = 180
then
13x + 24 = 180
then
13x = 156
then
x = 156/13 = 12
