Answer:

Reflection over the x-axis

Step-by-step explanation:

To get from Triangle A to Triangle B, Triangle A must be reflected over the x-axis. On Triangle A, the left-most point is at (1, -2). The corresponding point on Triangle B is at (1, 2). The rule for reflecting over the x-axis is (x, y) -> (x, -y). So, (1, -2) -> (1, 2).

I hope this helps :))

If a graph of y=-4x +2 were changed to a graph of y=-4x+5, how would the y- intercept change?

Dmitry [639]

Answer:

So if y=-4x+2 was changed to y=-4x+5, then the y-intercept would increase by 3.

The y-intercept was (0,2) then it becomes (0,5) in the new line.

Step-by-step explanation:

The slope-intercept form a line is y=mx+b where m is the slope and the y-intercept is b.

Both of these equations given are in this form.

y=-4x+2 when compared to y=mx+b you see that m=-4 and b=2.

Since b=2 then the y-intercept is 2.

y=-4x+5 when compared to y=mx+b you see that m=-4 and b=5.

Since b=5 then the y-intercept is 5.

So if y=-4x+2 was changed to y=-4x+5, then the y-intercept would increase by 3.

One sphere has a radius of 3 inches and another sphere has a radius of 6 inches. The volume of the larger sphere is about how ma

NikAS [45]

Answer:

Step-by-step explanation:

First off, we need to recognize that the formula for the volume of a sphere is $\frac{4}{3} \pi r^3$ .

Then, we can plug in our r values one at a time.

The volume for the sphere with a 6-inch radius is about 904.779.

The volume for the sphere with a 3-inch radius is about 113.097.

To find how much greater the larger sphere is, we simply create a ratio between the two numbers: $\frac{904.779}{113.097}$

Do the division to find that the volume of the larger sphere is about 8 times the volume of the smaller sphere.

What is the value of x?

Molodets [167]

Answer:

x = 4√5

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Trigonometry

Pythagorean Theorem: a² + b² = c²

Step-by-step explanation:

Step 1: Define

We are given a right triangle. We can use Pythagorean Theorem.

a = 19

b = x

c = 21

Step 2: Find x

Substitute: 19² + x² = 21²
Isolate x term: x² = 21² - 19²
Evaluate: x² = 441 - 361
Subtract: x² = 80
Isolate x: x = √80
Simplify: x = 4√5

And we have our final answer!
