Answer:

Step-by-step explanation:

You are trying to find the value of K, so to do that you need to get k by itself (example : K= 3-5 instead of K+5= 3)

So in 1a i would simplify 7k-3k= 4k

then 4k=11

now to get rid of the 4 and get the k alone- you DIVIDE 4k by 4 and divide 11 by 4 cause you need to do it on both sides of the equation, it should look like this.

4k= 11

-   =  -

4      4

(4k over 4 and 11 over four)

so the answer is k = 2.75  cause 11/4 = 2.75

#1. 105.5 because of the nine 4 goes to 5

#2. 67,990,000 because of the 4 it doesn't go up

#3. -4.1 because of the 4 the 0 goes to 1

if the number place before the one you are rounding is 5,6,7,8,or 9you go up by one and the rest becomes zeros

if the number place before the one you are rounding is 0,1,2,3,or 4 you stay the same and the rest becomes zeros

If the line formed by equation 1 is parallel to the line formed by equation 2, fill in the missing value below.
madreJ [45]

Answer:

y =-\frac{3}{2}x + 6

Step-by-step explanation:

Given

y = []x + 6 --- equation 1

y = \frac{2}{3}x + 10 --- equation 2

Required

Fill in the blank

A linear equation is represented as:

y = mx + b

Where m represents the slope

If (1) and (2) are perpendicular, then:

m_1 = -\frac{1}{m_2}

In y = \frac{2}{3}x + 10 --- equation 2

m_2 = \frac{2}{3}

So, we have:

m_1 = -\frac{1}{m_2}

m_1 = -\frac{1}{2/3}

m_1 = -\frac{3}{2}

Hence, the complete equation is:

y =-\frac{3}{2}x + 6
