Answer:

$A' = (-1,6)$

$B'= (-3,1)$

$C' = (-7,2)$

Step-by-step explanation:

Given

$A = (1,6)$

$B = (3,1)$

$C = (7,2)$

Required

Reflect over the y-axis

When a point is reflected over the y-axis, the rule is:

$(x,y)=>(-x,y)$

So, points ABC becomes:

$A = (1,6)$

$B = (3,1)$

$C = (7,2)$

$A' = (-1,6)$

$B'= (-3,1)$

$C' = (-7,2)$

A school had 1,200 students last year and only 1,080 students this year. What was the percentage decrease in the number of stude

jeyben [28]

Answer: 10%

First off, you need to divide 1200 with 1080.

1200 - 1080 = 120.

Next, divide 120 with the original number.

120 / 1200 = 0.1

Then, multiply 0.1 with 100.

100 x 0.1 = 10

Finally, add a % at the end.

10 -> 10%

So in summary, your answer is 10%

Check out attachment:) I don't understand how do you find out the length ?? pls help with explanation thx

Answer:

x=3.89

Step-by-step explanation:

I'll go in depth for you.

Before we figure out what we do, let understand what we know about this triangle.

We know that both triangles have a angle that measure 27°.
We also know EH=5
FG=9
ZG=7
We need to know how to find EZ

Notice how line EG and HF intersect at Angle Z. We know that if two lines intersect at an angle, it form angles called vertical angles. This means that the two angles that are vertical to each other are congruent.

This means that angle Z in both triangles both measure the same.

Now since both triangles have 2 congruent corresponding angles, we can say that the Triangles are Similar due to the Angle-Angle Postulate.

"If two corresponding angles of two triangles are congruent, then the two triangles are similar."

What is mean when Triangles are similar? 

It means that the similar triangles corresponding angles are equal and their sides are in proportion.

The corresponding sides are 

EH and GF

EZ and ZG

HZ and HF.

Our proportion formula for similar triangles is 

Any two sides of the first triangle divided by each other must equal the two corresponding sides of the second triangles divided by each other respectively.

We know FG and ZG so let set up our first fraction

 $\frac{fg}{zg}$ 

The corresponding sides of both are 

EH and EZ respectively so our proportion looks like
 $\frac{fg}{zg} = \frac{eh}{ez}$ 
Plug in the values for each. Let x represent the value of EZ
 $\frac{9}{7} = \frac{5}{x}$ 
Cross Multiply
 $9x = 35$ 
 $x = 3 \frac{8}{9} = 3.89$ 
So x=3.89
