vesna_86 [32]3 years ago
6 0

Answer: k < 3

Step-by-step explanation: Just like any of your two-step equations, in this inequality, start by isolating the k term which in this case is 5k by subtracting 3 from both sides. That leaves you with 5k < 15.

To get <em>k</em> by itself, divide both sides by 5 and <em>k < 3</em>.

Simplify the following expression (30/45g+20)-(8/9g+7)
den301095 [7]

The answer is: 13-\frac{2}{9}g

The explanation is shown below:

1- You have the following expression given in the exercise:

(\frac{30}{45}g+20)-(\frac{8}{9}g+7)

2- When you multiply signs, you obtain:

\frac{30}{45}g+20-\frac{8}{9}g-7

3. Now, you must add like terms, as following:

-\frac{2}{9}g+13

4. Therefore, you have that the expression simplified is:

13-\frac{2}{9}g

What is an equation of the line that passes through the points (-4,-5) and<br> (-8, -2)?
Katena32 [7]

Step-by-step explanation:

first we need to find the slope of the line.

the slope is the ratio of "y coordinate change / x coordinate change" when going from one point to the other.

we see here

x changes by -4 (from -4 to -8).

y changes by +3 (from -5 to -2).

so, the slope is +3/-4 = -3/4

there are two main forms for the equation of a line :

the slope-intercept form

y = ax + b

and the point-slope form

y - y1 = a(x - x1)

where "a" is the slope, and (x1, y1) is a point on the line.

we can pick any point, and I would pick (-4, -5).

so we get as point-slope form

y + 5 = -3/4 × (x + 4)

or for the slope intercept form we simplify the point-slope form

y + 5 = -3/4 x + -3/4 × 4 = -3/4 x - 3

y = -3/4 x - 8
