Answer:

1. b. 4/7

2. c. 3

Step-by-step explanation:

To find the slope

m = (y2-y1)/(x2-x1)

m= (7-3)/(5 - -2)

= (7-3)/(5+2)

= 4/7

m = (y2-y1)/(x2-x1)

m= (5-2)/(2 - 1)

= 3/1

The graph below shows the solution set of which inequality ?

Anestetic [448]

Answer:

E. $|x| < 100$ .

Step-by-step explanation:

The solution of an absolute value function of the form $|x| < a$ represents the set of values of $x$ so that $-a < x < a$ . The solution must be at least $|x| < 7$ . Hence, the right choice is $|x| < 100$ .

The perimeter of a rectangle is 34 units. Its width is 6.5 point, 5 units.

12345 [234]

<h3><u>Question:</u></h3>

The perimeter of a rectangle is 34 units. Its width W is 6.5 units.

Write an equation to represent the perimeter in terms of the length L, and find the value of L

<h3><u>Answer:</u></h3>

The length of rectangle is 10.5 units

<h3><u>Solution:</u></h3>

Given that,

Perimeter of rectangle = 34 units

Width of rectangle = 6.5 units

Let "L" be the length of rectangle

<em><u>The perimeter of rectangle is given by formula:</u></em>

Perimeter = 2(length + width)

<em><u>Substituting the values we get,</u></em>

$34 = 2(L + 6.5)$

Thus the equation is found

<em><u>Solve for "L"</u></em>

$L + 6.5 = \frac{34}{2}\\\\L + 6.5 = 17\\\\L = 17 - 6.5\\\\L =10.5$

Thus length of rectangle is 10.5 units

What is the measure of an angle if the measures of its two adjacent supplementary angles add up to 100°?

Sindrei [870]

<h3>Answer: 130</h3>

Explanation:

Let x be the unknown angle we want to find.

Let y be adjacent and supplementary to x. This means x+y = 180

Let z also be adjacent and supplementary to x. So x+z = 180 also

Subtracting the two equations leads to y-z = 0 and y = z. So effectively we've proven the vertical angle theorem.

Since the supplementary angles to x add to 100, we know that y+z = 100. Plug in y = z and solve for z

y+z = 100

z+z = 100

2z = 100

z = 100/2

z = 50

Therefore,

x+z = 180

x+50 = 180

x = 180-50

x = 130
