Can y’all help me on question 10 please?

Example 1: One-Step Inequalities

A bag of candy is split between us and our little brother. The bag says it has at most 28 pieces of candy in it. There are 15 candies in our bag, and x candies in our brother's bag, and we have to make sure he doesn't have more than us (of course). We can write an inequality expressing the number of candies in the bags.

We know that our bag has 15 candies.

We know that his bag has x candies.

We know that up to 28 candies were split between both bags, no more.

Since we know that x + 15 can't be more than 28, it must be less than or equal to 28. x + 15 ≤ 28

Now that we have an inequality expressing our candy, we solve for x. To do that, we subtract 15 from both sides.

x + 15 ≤ 28

x + 15 – 15 ≤ 28 – 15

x ≤ 13

Sweet, literally. Our brother has 13 or fewer pieces of candy, so no way does he have more candy than us. Until, in a moment of weakness (er, kindness) we share a few of our pieces with him. Now it's even sweeter.

Example 2: Two-Step Inequalities

A candy store owner saw us share our candy with our brother and was so impressed he gave us a $30.00 gift card. Tax free even! We decide to buy a giant candy bar for $13.00 and then some lollipops with the remaining money. If each lollipop is $0.90, we can write and solve an inequality expressing how many lollipops we can buy.

We know that the amount we spend needs to be less than or equal to $30.00.

We know we want to buy x lollipops.

We know that each lollipop is $0.90, so the total cost of the lollipops is $0.90x.

We know the candy bar costs $13.00.

So the total cost of the candy is $13 + $0.90x, and this needs to be less than or equal to $30.00. 13 + 0.90x ≤ 30

Now we solve for x, which is the number of lollipops we can buy. We want to get x by itself, so start by subtracting 13 from both sides.

13 + 0.90x ≤ 30

13 + 0.90x – 13 ≤ 30 – 13

0.9x ≤ 17

Divide both sides by 0.9 to finish up. We recommend nabbing a calculator for this part.

We need to buy less than 18.89 lollipops, so we can buy 18 whole lollipops and have some change to spare.

Answer:150 watts

Step-by-step explanation: Alright so first we need to know our equation and what we're given. So for the equation its P=w/t where work also equals change in energy. So if time is 1,600 seconds and work or energy is 240,000 J then Power equals 240,000J/1,600 sec = 150 Watts

Answer:

slope = 3

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, - 7) and (x₂, y₂ ) = (2, 5) ← 2 points on the line

m = [tex]\frac{5+7}{2+2}[/tex] = [tex]\frac{12}{4}[/tex] = 3

Answer: y = -1/3x + 17/3

Step-by-step explanation:

Hey there! I will be showing and giving the formula/steps to solve this problem. If there are any questions then feel free to ask in the comments.

Formula: y = mx + b

Step 1 - Find M

m = (6 - 4) / (-1 - 5) = -2/6 = -1/3

The m is the slope.

Step 2 - Use (5, 4) to find point B

y = -1/3x + b

4 = 1/3 * 5 + b

b = 17/3

Answer: y = -1/3x + 17/3

You will plugin 4 for y and b is the intercept.

~I hope I helped you :)~

Answer:

(0, 10 )

Step-by-step explanation:

Given

5x + 3y = 30

To find the y- intercept let x = 0 in the equation and solve for y.

5(0) + 3y = 30 , that is

3y = 30 ( divide both sides by 3 )

y = 10 ← y- intercept ⇒ (0, 10 )

Step-by-step explanation:

Using zero product rule, we have -(x - 8)(x + 2) = 0.

Answer:

y = [tex]-\frac{1}{3}x-\frac{2}{3}[/tex]

Step-by-step explanation:

Let the equation of the line is,

y = mx + b

m = Slope of the line

b = y-intercept

Since, slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Since, the given line passes through two points (-5, 1) and (4, -2)

Slope of the line 'm' = [tex]\frac{1+2}{-5-4}[/tex] = [tex]-\frac{1}{3}[/tex]

Equation of the line will be,

y = [tex]-\frac{1}{3}x+b[/tex]

Since, this line passes through (4, -2),

-2 = [tex]-\frac{4}{3}+b[/tex]

b = [tex]\frac{4}{3}-2[/tex]

b = [tex]-\frac{2}{3}[/tex]

Therefore, equation of the line will be,

y = [tex]-\frac{1}{3}x-\frac{2}{3}[/tex]

Answer:

B. 520

Step-by-step explanation:

Partial quotient is simply the method used to find the value of a quotient by dividing bits by bits until you get to the answer. For instance if you want to divide 124/4

Whatever closest multiple of 4 to 124 you remember, write it down. For instance I remember 80 first.

80 is the 20th multiple of 4 (80÷4 = 20).

Then subtract the number from the original number you want to divide

124 – 80 = 44

Again, write down the closest multiple of 44 you remember. To me is 40, and it is the 10th multiple.

Subtract 40 from 44 you have 4 left.

It's now easy to divide 4 by 4 which is 1.

To now get the quotient in total, you'll add up

20 + 10 + 1 = 31.

Therefore, to use partial quotient in this problem, the best choice to begin with will be 520 because it is the 20th multiple of 26. Although 780 is the 30th multiple of 26, 520 will be easier to remember. For this reason, it is the best choice.
