Answer:

I can help with number 7 if you want

1. Equation

y=15x + 10

This is the answer because 10 intercepts on the y axis and it says $15 dollars each.

2. -2 so you do y-y and x-x. In this case its 4-2 and 2-3 which equals 2 and -1 . Which divided equals -2.

Sorry I can't figure out the rest but I did do these ones.

Solving Square Roots Worksheet (x - k)^2 : Part 1

iVinArrow [24]

Answer:

1. x = +/- 2 $\sqrt{2}$ - 7

2. x = $3$ +/- $2i\sqrt{3}$

3. n = $2$ +/- $i\sqrt{2}$

Step-by-step explanation:

1. Divide both sides by 2: (x + 7)^2 = 8

Square root both sides: x + 7 = +/- 2 $\sqrt{2}$

Subtract 7 from both sides: x = +/- 2 $\sqrt{2}$ - 7

2. Square root both sides: x - 3 = $\sqrt{-12}$

Since there is a negative inside the radical, we need to have an imaginary number: $i=\sqrt{-1}$ . So, $\sqrt{-12} =i\sqrt{12} =2i\sqrt{3}$

Add 3 to both sides: x = $3$ +/- $2i\sqrt{3}$

3. Divide by -5 from both sides: (n - 2)^2 = -2

Square root both sides: n - 2 = $\sqrt{-2}$

Again, we have to use i: $n-2=\sqrt{-2} =i\sqrt{2}$

Add 2 to both sides: n = $2$ +/- $i\sqrt{2}$

Hope this helps!

Write a equation for 10 less than j is 35

kakasveta [241]

Answer:

$j - 10 = 35$

Step-by-step explanation:

Given: 10 less than $j$ is 35.

To find: The equation of the given situation.

Solution: We need to write an equation for 10 less than $j$ is 35.

Here, we will break down the sentence to form the equation.

10 less than $j$ means $j - 10$ .

Then, it says 10 less than $j$ is 35 which means it is equal to 35.

So, the sentence 10 less than $j$ is 35 can be written as 10 less than $j$ is equal to 35.

Now, 10 less than $j$ is equal to 35 can be shown as $j - 10 = 35$ .

Therefore, the required equation is $j - 10 = 35$ .

A farmer grows two types of grain in his fields. He has a seed budget of $17,000.00 and has spent $9,200.00 to plant wheat seed

Zarrin [17]

Okay so first you have to subtract 17000 from 9200 to see how much money you have left to spend. Then once you get that number, which is 7800, you have to see what's that maximum number of acres that you can get. So you divide 7800 from 41.00 and you can get your answer. Your answer will be 190 acres. 190 acres is the highest you can go without going over budget.
