5 0

Answer:

They completed 13, 3 credit classes

Step-by-step explanation:

1. Make 2 formulas. In this case: x+y=18

and 3x+4y=59

2. Then multiply x+y=18 by 3 and subtract the two equations.

Find y which is 5 and input into the equations. Then find your answer.

In the diagram g|| h, m&lt;1=(4x+36) and m&lt;2=(3x-3) <br><br> What is the measure of &lt;3
Roman55 [17]

Answer:

60°

Step-by-step explanation:

Since g||h the sum of angle 1 and angle 2 must be equal to 180

4x + 36 + 3x - 3 = 180

7x + 33 = 180

7x = 147

x = 21

The sum of angle 1 and angle 3 is equal to 180 because they are complementary angles

m<1 = 4x + 36 ➡ 4 × 21 + 36 = 120° so angle 3 = 60°

Which transformation will map Figure L onto Figure L’?
Paha777 [63]

Answer:

Transformation rule: T(6,0)

Step-by-step explanation:

In given figure L, Vertices of triangle ABC

A(-3,7)     B(-4,2)  C(-2,4)

In given figure L', Vertices of triangle A'B'C'

A'(3,7)     B(2,2)    C'(4,4)

Please see the attachment for the vertices of A, B and C.

We have to find the map rule how to translate A to A'

T(x,y)\rightarrow T'(x+a,y+b)

A(-3,7)\rightarrow A'(3,7)

B(-4,2)\rightarrow B'(2,2)

C(-2,4)\rightarrow C'(4,4)

We can see x changes to 6 unit right and no change in y

So, Translation rule

T(x,y)\rightarrow T'(x+6,y+0)

Figure L change to figure L' by rule T(6,0)

Thus, Transformation rule is T(6,0)
