Answer:

15^2+x^2=22^2

225+x^2=484

x^2=259

x=16.09 feet

Step-by-step explanation: 15^2+x^2=22^2

225+x^2=484

x^2=259

x=16.09 feet

When the points below are connected, they will form triangle ABC. Show and state whether this triangle has a right angle or not.
cluponka [151]

Answer:

See explanartions below

Step-by-step explanation:

Given the coordinates A(-6,3) B(0,5) C(2,-1)

We first need to get the slope of AB, BC and AC

For AB;

A(-6,3) B(0,5)

Mab = 5-3/0-(-6)

Mab = 2/6

Mab = 1/3

For BC;

B(0,5) C(2,-1)

Mbc = -1-5/2-0

Mbc = -6/2

Mc = -3

For AC:

A(-6,3) C(2,-1)

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

MAc = -4/8

Mac = -1/2

Taking the product of Mab and Mbc

Mab * Mbc = 1/3 + -3

Mab * Mbc = -1

<em>Since the product of Mab and Mbc is -1, hence AB abd BC are perpendicular showing that one of the angle of triangle ABC is 90 degrees</em>

What are some strategies you could use to find a relationship between x and y?
tia_tia [17]

Answer:

The statistical relationship between two variables is referred to as their correlation. A correlation could be positive, meaning both variables move in the same direction, or negative, meaning that when one variable's value increases, the other variables' values decrease.

Oh my goodness please help its confusing.
Irina18 [472]

Probably the easiest way to do these is to convert them to slope intercept form by solving for y.  When we have y=mx+b, we read off the slope m.

-5x + 2y = 10

Add 5x to both sides,

2y = 5x + 10

Divide both sides by 2,

y = (5/2) x + (10/2)

Obviously 10/2=5 but we don't care about that for this problem.  We read off the slope as

Answer: 5/2, last choice


12 = 4x - 6y

Adding 6y and subtracting 12,

6y = 4x - 12

Dividing by 6,

y = (4/6) x - (12/6)

y = (2/3) x - 2

Answer: 2/3
