Answer:

Combine like terms.

Step-by-step explanation:

In order to solve the problem, we need to combine like terms.

5 - 2x < 8x - 3

-2x - 8x < -3 - 5

-10x < -8

10x > 8

5x > 4

x > 4/5

Hope this helps!

If possible write the following equation in slope-intercept form. y – = 9

elena55 [62]

Answer with Step-by-step explanation:

We are given that

$\frac{y-x}{9}=9$

$y-x=9\times 9=81$

$y=x+81$

Compare with slope-intercept form

$y=mx+b$

Where m=Slope of line

b=y-intercept

a.We get slope=m=1

b.b=81

c) To find the x- intercept

Substitute y=0

$x+81=0$

$x=-81$

x-intercept at x=-81

Tennis balls are sealed in a pressurized container to maintain the rebound percentage

Darina [25.2K]

Answer:

Rounding the results to the next hundredth, we have:

Bounce 1: 2 * 0.55 = 1.10 meters

Bounce 2: 1.10 * 0.55 = 0.61 meters

Bounce 3: 0.61 * 0.55 = 0.34 meters

Bounce 4: 0.34 * 0.55 = 0.19 meters

Bounce 5: 0.19 * 0.55 = 0.10 meters

Bounce 6: 0.10 * 0.55 = 0.06 meters

Bounce 7: 0.06 * 0.55 = 0.03 meters

Step-by-step explanation:

Rebound percentage = 55% = 0.55

Bounce 1: 2 * 0.55 = 1.10 meters

Bounce 2: 1.10 * 0.55 = 0.605 meters

Bounce 3: 0.605 * 0.55 = 0.33275 meters

Bounce 4: 0.33275 * 0.55 = 0.1830125 meters

Bounce 5: 0.1830125 * 0.55 = 0.10065688 meters

Bounce 6: 0.10065688 * 0.55 = 0.05536128 meters

Bounce 7: 0.05536128 * 0.55 = 0.0304487 meters

Rounding the results to the next hundredth, we have:

Bounce 1: 2 * 0.55 = 1.10 meters

Bounce 2: 1.10 * 0.55 = 0.61 meters

Bounce 3: 0.61 * 0.55 = 0.34 meters

Bounce 4: 0.34 * 0.55 = 0.19 meters

Bounce 5: 0.19 * 0.55 = 0.10 meters

Bounce 6: 0.10 * 0.55 = 0.06 meters

Bounce 7: 0.06 * 0.55 = 0.03 meters

Pythagorean Theorem: a² + b² = c²

Step-by-step explanation:

Step 1: Define

Leg a = x

Leg b = 64

Hypotenuse c = 80

Step 2: Solve for x

Substitute: x² + 64² = 80²
Isolate x term: x² = 80² - 64²
Exponents: x² = 6400 - 4096
Subtract: x² = 2304
Isolate x: x = √2304
Evaluate: x = 48

Find the value of b.

Scrat [10]

Answer:

Step-by-step explanation:

The secant- tangent angle b is half the difference of the measures of the intercepted arcs , then

b = $\frac{1}{2}$ ( 180 - 35) = $\frac{1}{2}$ × 145° = 72.5° → B
