ABC is translated left 3 units to form the image ∆A′B′C′.

What are the coordinates of the vertices of ∆A′B′C′ ?

Enter your answer by filling in the boxes.

Answers

Answer:

The coordinates of triangle A'B'C' are A'(-5,-1) B'(-1,-1) C'(-1,2)

Step-by-step explanation:

Translations

Given a point A(x,y), translating A by h units to the left will map it to A'(x-h,y).

The triangle ABC has coordinates: A(-2,-1) B(2,-1) C(2,2). Then translating the triangle left by h=3 units, the points are:

A'(-2-3,-1) B'(2-3,-1) C'(2-3,2)

A'(-5,-1) B'(-1,-1) C'(-1,2)

The coordinates of triangle A'B'C' are A'(-5,-1) B'(-1,-1) C'(-1,2)

Length of box = 15 in

Width of box = 30 in

Height of box = 24 in

Find:

Surface area

Computation:

Surface area = 2h[l+b]

Surface area = 2(24)[30 + 15]

Surface area = 48 x 45

Surface area = 2,160 in²

Can you find the y=mx+b?

Answers

Answer:

y=-2x+7

Step-by-step explanation:

Slope is y(2)-y(1)/x(2)-x(1)

I chose (1,5)(0,7) as my two points and got -2 as my slope

Then, I got (0,7) as my y-intercept because it was in the table.

So, the equation is y=-2x+7

A bag contains 2 red,5 blue,6 yellow, and 3 green crayons. What is the probability of selecting a red crayon, then without replacing it selecting an odd number that is (red, then green)
A.0
B.0.25
C.01
D.0.025

Answers

Answer: D.0.025

Step-by-step explanation:

Given: A bag contains 2 red,5 blue,6 yellow, and 3 green crayons.

Total crayons: 2+5+6+3=16

Probability of getting red crayon= [tex]\dfrac{\text{Number of red crayons}}{\text{Total}}[/tex]

[tex]=\dfrac{2}{16}=\dfrac18[/tex]

Without replacement, the probability of getting green crayon = [tex]\dfrac{\text{Number of green crayons}}{\text{Total}-1}[/tex]

[tex]=\dfrac{3}{15}=\dfrac15[/tex]

Required probability P(red then green)= [tex]\dfrac18\times\dfrac15=\dfrac1{40}=0.025[/tex]

Hence, correct option is D.0.025
