Mathematics

Westkost [7]3 years ago

Answer:

Perpendicular because the slope of the first one is 1. While the slope of the second one is - 1. On the other hand the slope of the third one is 1. So the 1 first one and the third one are parallel.

Step-by-step explanation:

Y=mx+b, m is slope

Y=x+5, 1 is slope

X+y=7

Y=7-x, - 1 is slope

3. Y=mx+b

-2=0+b, at point (0,-2)

b=-2

Y=mx-2

0=2m-2, at point (2,0)

2m=2

m=1, AKA the slope

For each equation, enter two more equations using the same numbers that express the same relationship in a different way. 3+2=5
Zepler [3.9K]

Answer:

3 = 5 - 2

2 = 5 - 3

Step-by-step explanation:

Given

3 + 2 = 5

Required

Express in different ways

The first way is:

3 + 2 = 5

Subtract 2 from both sides

3 + 2 -2= 5 - 2

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

Another way is:

3 + 2 = 5

Subtract 3 from both sides

3 - 3 +2 = 5 - 3

2 = 5 - 3 --- (2)

HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Gekata [30.6K]

Answer:

The ordered pairs of A and C are not functions

Step-by-step explanation:

To determine if the ordered pairs are a function you look at the x values to see if they repeat. You don't want one input(x values) to lead to two outputs(y values). This would mean that you are never sure which output you will get.

In the answer A the x value "2" repeats, in the answer C the x value "1" repeats thus not making them functions.

Picture is shown above<br>suppose that y varies directly with x, and y=12 when x=15​
a_sh-v [17]

Step-by-step explanation:

Since y is directly proportional to x,

we have y = kx, where k is a real constant.

When x = 15, y = 12.

=> (12) = k(15), k = 0.8.

Therefore we have y = 0.8x.

When x = 2, y = 0.8(2) = 1.6.

The answer is y = 1.6 when x = 2.
