Answer:

X^2-4

Step-by-step explanation:

Let x be our number.

So we square the number because it says 4 less than the square number.

So we have x^2.

Now, we have to take 4 less than that.

So x^2-4 is our answer.

(This can also be factored because it is in the form a^2-b^2)

(This can be rewritten as (x+2)(x-2))

3 - 4z - 4 = 3z - 2 - z

-4z - 1 = 2z - 2

2z + 4z = -1 + 2

6z = 1

z = 1/6

Hope this helps!

Answer:

d = 2.75 or 11/4

Step-by-step explanation:

15 = 5 + 4(2d - 3)

15 = 5 + 8d - 12

15 = 8d - 7

<u>+7        + 7</u>

22 = 8d

22/8 = d

2.75 = d

Check:

15 = 5 + 4(2(2.75) - 3)

What is the equation in slope-intercept form of a line (y = mx + b) that has aslope of 3 y-intercept of 6?
arsen [322]

The equation of the line is y = 3x + 6

<h3>What are linear equations?</h3>

Linear equations are equations that have constant average rates of change.

Note that the constant average rates of change can also be regarded as the slope or the gradient

<h3>How to determine the equation of the line?</h3>

The given parameters are

Slope, m = 3

y-intercept, c = 6

A linear equation is represented as

y = slope * x + y-intercept

i.e.

y = mx + c

So, we have

y = 3x + 6

Hence. the linear equation is y = 3x + 6
