what is the equation of a line that passes through the points (0,5) and (4,8)? write the answer in slope-intercept form.
Sergio039 [100]

Answer:

<h2>y = 3/4x + 5</h2>

Step-by-step explanation:

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept → (0, b)

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (4, 8) and (0, 5) → b = 5.

Calculate the slope:

m=\dfrac{5-8}{0-4}=\dfrac{-3}{-4}=\dfrac{3}{4}

Therefore we have the equation of the line:

y=\dfrac{3}{4}x+5

If m 2 n, which inequalities must be true? Check all that apply.
anzhelika [568]

Answer:

(a)\ m+ 2.1 > n + 2.1

(b).\ m - (-4) > n - (-4)

(c)\ 9 +m> 6 + n

Step-by-step explanation:

Given

m > n

Required

Select true inequalities

(a)\ m+ 2.1 > n + 2.1

Subtract 2.1 from both sides

m > n

This is true

(b).\ m - (-4) > n - (-4)

Open brackets

m + 4 > n + 4

Subtract 4 from both sides

m > n

(c)\ 9 +m> 6 + n

m> -9+6 + n

m> n-3

This is also true

Which expression is equivalent to 4x+3x+4-2x
kvv77 [185]

Answer:

5x+ 4

Step-by-step explanation:

First, put all of the x variables together. So 3x+4x=7x

7x + 4 -2x  Since the 2x is negative you can subtract it from 7x and get 5x.

you can not add the four to the 5x because it does not have a matching variable.

So, you have: 5x+ 4

Help please I needed!!!!
faust18 [17]

Answer:

Step-by-step explanation:

4. f(x) = √(x + 4)

f(5) = √(5+4) = √(9) = 3

5. g(x) = x^12 - x^5

  g(-1)=          (-1)^12 - (-1)^5

             1 - (-1) = 1 + 1 = 2
