HELP IM LITERALLY SOBBING

Mathematics
2 answers:
Elena L [17]3 years ago
7 0

Answer:

y=1/4x+2.75

Step-by-step explanation:

two coordinates are: (5,4) and (-3,2)

the linear function is y=mx+b

m=slope

b=y-intercept

first, find the slope

the formula to find the slope is y2-y1/x2-x1

2-4/-3-5=

-2/-8=

1/4

Now you know 1/4 is the slope.  Plug that into the function

y=1/4x+b

Now find the y-intercept

to do that, take one of your coordinates and plug the x and y values into the function.

I will use (-3,2)

2=1/4(-3)+b

2=-3/4+b

11/4=b

(or 2.75 decimal form)

Plug the y-intercept into the function and you're done

y=1/4x+2.75

What is 3=7(4 - 2u)-6u
alisha [4.7K]

Answer:

u = 5/4

Step-by-step explanation:

to evaluate for the value of u we would simply open the bracket and then evaluate for the value of u by collecting the like terms together.

solution

3=7(4 - 2u)-6u

3 = 28- 14u - 6u

collect the like terms

3 + 14u + 6u = 28

20u = 28 - 3

20u = 25

divide both sides by the coefficient of u which is 20

20u/20 = 25/20

u = 5/4

Two numbers have an average of 18, and a difference of 10. Form two equations and solve them to find these
Troyanec [42]
Answer: x = 23 and y = 13

Explanation:

let x and y be the two number.

Where:

(x + y)/2 = 18 => x + y = 18 x 2 = 36

and:

x - y = 10

Thus we get:

x + y = 36 (1)
x - y = 10 (2)

Add (1) and (2):
x + y + x - y = 36 + 10
2x = 46
x = 23

If x = 23

then x - y = 10
23 - y = 10
-y = -13
y = 13

Find the slope of the line 4x-8y=15
Arisa [49]

Answer:

-1 \frac{7}{8}

-8y=15-4x

-8y/-8=15-4x/-8

y=-1 7/8+1/2x

slope is -1 7/8
