x - 27 = 62 → ( add 27 to both sides )

x - 27 + 27 = 62 + 27

x = 89

drag first box then box with x = 89

The slope of the line is..? A. -2 B. -1 C. 1 D. 2

Nezavi [6.7K]

Answer:

B, -1

Step-by-step explanation:

on a graph with 2 points (or more) listed, you can count the points from each coordinate to determine slope (which is rise/run also known as y/x)

going from left to right, we start at (1,4) and count down from (1,4) to (3,2), we go down 2 units

going from left toright again, we start from (1,2) (our point we counted down to from (1,4) and count to the left 2 units

we are now at (3,2)

it took us 2 points down (negative) and 2 to the right (positive) to get from (1,4) to (3,2)

using rise/run we have the following:

-2/2 < we can simplify this further by dividing -2 by 2 and getting 1

the answer is B, -1

ANOTHER WAY

another way we can calculate the slope is by the following formula

y2 - y1/ x2- x1

(1,4) is our x1 and y1, while (3,2) is our x2, y2. we plug this into the formula and we get:

y2 - y1 = 2 - 4 = -2

x2 - x1 = 3 - 1 = 2

-2 / 2 = -1

we still have the same answer, and this formula is useful when you dont have a graph to count down from

Triangle X Y Z is shown. Angle X Z Y is a right angle. The length of Z X is b, the length of Z Y is a, and the length of hypoten

valina [46]

Answer:

a is adjacent, b is opposite, c is the hypotenuse

Step-by-step explanation:

see the attached figure to better understand the problem

In the right triangle XYZ we have

The side a and side b are the legs and the side c is the hypotenuse (the greater side)

The side a is the adjacent side to angle Y and is the opposite side to angle X

The side b is the opposite side to angle Y and is the adjacent side to angle X

The side c is the hypotenuse

The sum of the angles X and Y is equal to 90 degrees because are complementary angles

therefore

a is adjacent, b is opposite, c is the hypotenuse

What’s the least common denominator for 1/6 and 7/8?

Alexandra [31]

Answer:

Step-by-step explanation:

Here's how we construct the LCD:

Factor the denominators 6 and 8: 6 = 2*3 and 8 = 2*2*2

The LCD involves 2*2*2 as well as 3:

LCD: 2*2*2*3 = 24. Note that 24 is divisible by both 6 and 8. There is no smaller LCD that is divisible by 6 and 8 both.
