I would love to but there's no question

Step-by-step explanation:

Answer: We have the following function:

f (x) = x ^ 2

We have the following transformation:

Expansions and horizontal compressions

The graph of y = f (bx):

If 0 <b <1, the graph of y = f (x) expands horizontally by the factor of 1 / b.

Applying the transformation:

y = (0.2x) ^ 2

The factor is:

1 / b = 1 / 0.2 = 5

Answer:

b. expanded horizontally by a factor of 5

Answer:

72

I hope this helps!

The equivalent expression is 6.

Option B is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

[tex]216^{1/3}[/tex]

6 x 6 x 6 = 216

This can be written as,

6³ = 216

Now,

[tex](6^3)^{1/3}[/tex]

= [tex]6^{3\times1/3}[/tex]

= 6

Thus,

The equivalent expression is 6.

Answer:

y = 3x - 6

Step-by-step explanation:

18 = 9x - 3y

3y + 18 = 9x

3y = 9x - 18

y = 3x - 6             < -- This is the answer

Hope this helps!

Answer:

Step-by-step explanation:

It's hard to tell what you really intend. I'll do it both ways.

Way One

9 + x/6 = 11          Subtract 9 from both sides.

x/6 = 11 - 9

x/6 = 2                 Multiply both sides by 6

x = 2 * 6

x = 12

1 + 3x = 1 + 3*12 = 1 + 36 = 37

Way Two

(9 + x)/6 = 11         Multiply both sides by 6

9 + x = 11 * 6         Simplify the right side

9 + x = 66            Subtract 9

x = 57

1 + 3*57 = 1 + 171 = 172

the last part was unformatted and i cant tell what it is, but point b after translated is (-2,3)

Answer:

51°

Step-by-step explanation:

Remember, all 3 angles must add up to 180°

We can tell that this triangle is a right triangle, or a triangle that has a 90° angle. We also have another angle given, which is 39°. Currently we have two angles given.

Since all 3 angles have to add up to 180°,

90 + 39 + x = 180°

129 + x = 180°

180 - 129 = x

x = 51°

The missing angle is 51°

To see if your calculation is correct, you could add all 3 angles, and it should give you 180 as a sum.

90 + 39 + 51 = 180

Correct!

A) 37+42=79(1.07)=84.53

B) you would take off the discount and that equals 59.25 then you would apply taxes 63.40

C)9.48 and 7.11

Step-by-step explanation:

Answer:

a) $84.53

37+42=79

79(0.07)=5.53

79+5.53=84.53

b) $56.50

You have to multiply the cost of both shoes by 0.25 to get the amount of money that Isaac gets discounted. Then you subtract that amount from the cost of the shoes to get the new price. Then you multiply the new price by 0.07 to get how much he will be taxed. Finally, you add the tax to the total.

c) Before the coupon is applied: $10.08

After the coupon is applied: $9.48

84(0.12)=10.08
