2. X^2=81 3. x^2=64 4. X^2=100 5. X ^2=121

1 answer:

4 0

X² = 81
x = $\pm$ √81
x = $\pm$ 9

x² = 64
x = $\pm$ √64
x = $\pm$ 8

x² = 100
x = $\pm$ √100
x = $\pm$ 10

x² = 121
x = $\pm$ √121
x = $\pm$ 11

When Elijah left his house in the morning, his cell phone battery was partially

lions [1.4K]

Answer:

The slope is -4.5

The slope means that Elijah's phone battery will decrease by 4.5 percent each hour.

Step-by-step explanation:

In the equation y = mx + b, m is the slope.

The coefficient in the equation B = 27 – 4.5t is -4.5. This means that -4.5 is the slope of the equation.

In the context of this problem, the slope will represent the percent that Elijah's phone battery will decrease per hour.

So, the slope means that Elijah's phone battery will decrease by 4.5 percent each hour.

Write the equation of the line in point-slope form of the given point and slope. This is an essay style question. If you hit the

svp [43]

Answer:

Step-by-step explanation:

The point-slope form of the equation will be expressed as;

y - y0 = m(x-x0) where;

m is the slope

(x0, y0) is the point on the line

Given

Slope m = 3/7

Point (x0, y0) = (7, -2)

Substitute into the equation;

y - y0 = m(x-x0)

y - (-2) = 3/7 (x - 7)

<em>Hence the equation in point-slope form is y + 2 = 3/7(x-7)</em>

If AABC = ADFE determine the values of x and y.

natita [175]

$8y - 5 = 99 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 8y = 99 + 5 \\ \: \: \: \: \: \: \: \: \: \: 8y = 104 \\ \: \: \: \: \: \: \: \: \: \: \: \: y= \frac{104}{8} \\ \: \: \: \ \: \: \: y = 13$

$\: \: \: \: \: \: 2y + x = 38.4 \\ 2(13) + x = 38.4 \\ \: \: \: \: \: \: 26 + x = 38.4 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: x = 38.4 - 26 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: x = 12.4$

Daniel [21]

Answer:

$100

Step-by-step explanation:

the equation to solve this is:

$y=12.5x+25$

$y=12.5x+25\\ =(12.5*6)+25\\ =75+25\\ =100$

(Assuming, of course, that this is a homework assignment and not you actually buying it cuz' in real life the numbers would be different from month to month)
