For triangle XYW, the slope of WX is , the slope of XY is 0.56, and the slope of YW is . Which statement verifies that triangle

Paha777 [63]

If lines through XY and YW form a 90° angle, so that Y is a right angle,

then the product of the slopes of the lines through XY and YW must be -1

let the slopes through X,Y and Y,W be $m_X_Y$ and $m_Y_W$ respectively

so

$m_X_Y*m_Y_W=-1$

$m_Y_W= \frac{-1}{m_X_Y}$

$m_Y_W= \frac{-1}{0.56}$

$m_Y_W= -1.786$

Right answer: $m_Y_W= -1.786$

Solve the compound inequality:<br>2x-8≥4 or 8x+7<15

MaRussiya [10]

An inequality<span> is a sentence with <, >, ≤, or ≥ as its verb. An example is 3x - 5 < 6 - 2x. To </span>solve<span> an inequality is to find all values of the variable that make the inequality true. Each of these numbers is a solution of the inequality, and the set of all such solutions is its </span>solution set<span>. Inequalities that have the same solution set are called equivalent inequalities.</span>

Questions 1-4 I'm very confused on this

Nadusha1986 [10]

Answer:

All four are linear
Slopes: 2, 1/2, - 2/3, 3/4

Step-by-step explanation:

<u>Rate of change is same for each step:</u>

10 per each 5

<u>Slope is:</u>

(25 - 15)/(5 - 0) = 10/5 = 2

<h3>Top right</h3>

<u>Rate of change is same for each step:</u>

1 per each 2

<u>Slope is:</u>

(6 - 5)/(3 - 1) = 1/2

<h3>Bottom left</h3>

<u>Rate of change is same for each step:</u>

-2 per each 3

<u>Slope is:</u>

(30 - 32)/(5 - 2) = -2/3

<h3>Bottom right</h3>

<u>Rate of change is same for each step:</u>

3 per each 4

<u>Slope is:</u>

(20 - 17)/(5 - 1) = 3/4

If m <5=42 what is m <4<br><br> 42<br> 48<br> 128<br> 138

Reika [66]

Answer:

48° or 138°

Step-by-step explanation:

$Complementary \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: Supplementary$

$90° = 42° + m∠4 \: \: \: \: \: 180°= 42° + m∠4$

$48°= m∠4 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 138° = m∠4$

I am joyous to assist you anytime.
