Y = 3.5(-10) + 5
y = -35 + 5
y = 30

y = 3.5(10) + 5
y = 35 + 5
y = 40

[30, 40]

Answer:

y-3 = (1/4)x; 4y = -4x +14; y=4

Step-by-step explanation:

>First find the equation of function A

general equation of a line is y=mx+b

m = (y2-y1)/(x2-x1)= (0-(7/2))/(-7-0) = (-7/2) *(1/-7) = 1/2

consider the point (-7,0)

0 = -7(1/2) +b

7/2 = b

Function A has the equation y= (1/2)x +7/2

>rewrite the equations to fit the standard form

y-3 = (1/4)x ; add 3 to both sides

y= (1/4) x +3

4y = -4x +14 ,divide by 4 both sides

y= -x + 7/2

y=4

> intercept less than A

y-intercept for function A , y= (1/2)x +7/2, is 7/2 =3.5

y-intercept for function y= (1/4) x +3 is 3

3 < 7/2, so the answer is y-3 = (1/4)x

> intercept equal to A

y-intercept for function A , y= (1/2)x +7/2, is 7/2

y-intercept for function y= -x + 7/2 is 7/2

7/2=7/2 , so the answer is 4y = -4x +14

> intercept greater than A

y-intercept for function A , y= (1/2)x +7/2, is 7/2 =3.5

y-intercept for function y=4 is 4

4 > 7/2

If B equals 7 what is the value of the expression 2 + (10 - B )?

avanturin [10]

We just need to plug in 7 for B!

Let's do it !

2 + (10 - 7)

We always start with the parenthesis first ! It's just a rule in math :)

10 - 7 = ?

10 - 7 = 3

Now we have ...

2 + 3

2 + 3 = 5

Your final answer is 5!

I hope I helped :) Just comment if you have any questions and remember to vote me "brainliest" if you like my answer !!!

Solve a=2b-c for b Can someone help me

Sauron [17]

Answer:

$b=\frac{a}{2} +\frac{c}{2}$

Explanation:

While solving literal equations could be quite overwelhming, simply solve it by using normal equation solving methods.

For example, if you were to solve 2x + 3 = 9

You would add 3 on both sides and divide both sides by 2 to determine x.

Do the same thing for literal equations, and if in doubts, plug in numbers to check your work.

Step-by-step explanation:

For this problem, add c on both sides, we do this because we are aiming to eliminate the c from both sides.

a+c =2b

In order to find the value of b, divide both sides by 2, we do this because we want to get rid of the coefficient.

This should leave you with the answer of b=a/2 + c/2
