Find the measure of the angle indicated. Find m UTW

Ghella [55]

You would find the measure of angle U which is 33. Then you would add 8x+12x and get 20x then you would add 33 and 7 and get 40 so you have 20x+40=180 (because all of a triangles measures = 180) then you would minus 40 from both sides you now have 20x=140 then divide by 20 and x=7 then you would go back and do 12(7) . Then your angle = 84

3. Try It #3 Write the point-slope form of an equation of a line with a slope of -2 that passes through the point (-2,2). Then r

vova2212 [387]

Answer:

Point-slope form of equation given as $y-2=-2(x+2)$ .

Slope-intercept form of equation is given as $y=-2 x-2$ .

Step-by-step explanation:

In the question, it is given that the slope of a line is -2 and it passes from (-2,2).

It is asked to write the point-slope form of the equation and rewrite it as slope-intercept form.

To do so, first find the values which are given in the question and put it in the formula of point-slope form. Simplify the equation to rewrite as slope-intercept form.

Step 1 of 2

Passing point of the line is (-2,2).

Hence, $x_{1}=-2$ and

$y_{1}=2 \text {. }$

Also, the slope of the line is -2.

Hence, m=-2

Substitute the above values in point-slope form of equation given by $y-y_{1}=m\left(x-x_{1}\right)$

$\begin{aligned}&y-y_{1}=m\left(x-x_{1}\right) \\&y-2=-2(x-(-2) \\&y-2=-2(x+2)\end{aligned}$

Hence, point-slope form of equation given as y-2=-2(x+2).

Step 2 of 2

Solve y-2=-2(x+2) to write it as slope-intercept form given by y=mx+c.

$\begin{aligned}&y-2=-2(x+2) \\&y-2=-2 x-4 \\&y=-2 x-4+2 \\&y=-2 x-2\end{aligned}$

Hence, slope-intercept form of equation is given as y=-2x-2.

1)The price of a pair of boot was reduced from $80 to $60. By what percentage

Elan Coil [88]

Answer:

1) 25%

2) $17.54

Step-by-step explanation:

1) The boots were reduced from $80 to $60, therefore the total amount they were reduced by in terms of money is $20. To find out what percentage $20 is of $80, you divide.

20/80 = 0.25

0.25 = 25 % (to change a decimal to a percentage, you multiply by 100)

2) 20% = 0.20 (to change a percentage to a decimal, you divide by 100)

To find 20% of $87.70, multiply 0.20 by 87.70.

87.70 x 0.20 = 17.54

Someone help me please

Sidana [21]

Answer:

4 (C)

Step-by-step explanation:

Slope (m) = Rise/Run (Change in y/Change in x)

This formula is the same as:

$m=\frac{y_2-y_1}{x_2-x_1}$

Let's go through each variable.

m is the slope, what we are trying to find.

y2 is the second value of y, 122 ft.

y1 is the first value of y, which is 68 ft.

Finally, we know that x2-x1 is the same as the change in x. The problem tells us that the roof goes over a horizontal distance of 4.5 yards. In this case, we don't need to know x2 and x1. We already know the change in x, so we add that to our formula. Here's what we have so far:

$m= \frac{122-68}{13.5}$

*note that 4.5 yards = 13.5 feet

The slope of the roof is 4.

What is the factored form of the following expression? <br><br> x^2 - x - 42

Crank

Answer:

(x - 7)(x + 6)

Step-by-step explanation:

Consider the factors of the constant term ( - 42) which sum to give the coefficient of the x- term ( - 1)

The factors are - 7 and + 6, since

- 7 × 6 = - 42 and - 7 + 6 = - 1

x² - x - 42 = (x - 7)(x + 6)
