Solve for x. (1 point) −3x + 2b > 8 x < the quantity negative 2 times b plus 8 all over negative 3 x > the quantity negative 2 times b plus 8 all over negative 3 x < the quantity 2 times b minus 8 all over negative 3 x > the quantity negative 2 times b minus 8 all over 3
Given:
[tex]-3x+2b>8[/tex]
To find:
The value of x.
Solution:
We have,
[tex]-3x+2b>8[/tex]
To find the value of x, we need to isolate x on one side.
Subtract 2b from both sides.
[tex]-3x>8-2b[/tex]
Divide both sides by -3. On multiplying or dividing an inequality by a negative number, we need to change the sign of inequality.
[tex]\dfrac{-3x}{-3}<\dfrac{8-2b}{-3}[/tex]
[tex]x<\dfrac{-2b+8}{-3}[/tex]
The required inequality for x is [tex]x<\dfrac{-2b+8}{-3}[/tex].
Therefore, the correct option is A.

What is the equation of the line that passes through the point (6, -1) and has a
slope of 1?
Answer:
y = x – 7
Step-by-step explanation:
Answer:
y= x -7
Step-by-step explanation:
The equation of a line can be written in the form of y=mx+c (also known as slope-intercept form), where m is the gradient and c is the y-intercept.
Given that the slope is 1, m= 1.
Substitute the value of m into the equation:
y= 1x +c
y= x +c
To find the value of c, substitute a pair of coordinates.
When x= 6, y= -1,
-1= 6 +c
c= -1 -6 (-6 on both sides)
c= -7
Thus, the equation of the line is y= x -7.

I need to find out the value of x in this triangle because I don’t understand the formula
Answer:
x = 55 degrees
Step-by-step explanation:
Firstly, as told by the question, we know that this is an isosceles triangle because AB and BC are the same length. This means that angle A and C will be equal. Next, we also know that all angles in a triangle will always add to 180 degrees. Therefore we can write an equation adding up all the angles to solve for x:
Angle A can be represented as 'x'
Angle B is represented 'x+15'
And Angle C can also be represented 'x' as it is equal to angle A
So our formula will be in this format: A+B+C=180
x+x+(x+15)=180
To solve this equation we first take out the brackets and combine like terms:
3x+15=180
Now we need to isolate 'x' so we will end up with a numerical value for it, which we do by subtracting 15 from both sides and then dividing both sides by 3:
3x+15-15=180-15
3x=165
3x/3=165/3
This gives us:
x=55

How exactly would I find a slope to a graph?
Answer:
If the graph is rising from left to right, like climbing a hill, the slope is positive (on a graph, you could count up y units divided by right x units). If it is going down from left to right (like sliding down a hill), the slope is negative (on a graph you have to count down y units and right x units).
Step-by-step explanation:
Answer:
Most people would do it by subtracting your 2 y points (any points) and dividing the by the two x points. Basically, y2-y1/x2-x1. Hoped I could help you on this one.

mary robertson sells tires at a large car service center. She earns 10% commission on the first $1000.15 percent on the next $2000 and 20% on sales for more than $3000 last week she sold $3400 worth of tires what is her total commission
Answer:
$1530 = 45% commission
Step-by-step explanation:
First, jot down the important facts:
• first $1000 = 10% comm.
• next $2000 = 15% comm.
• total more than $3000 = 20% comm.
• total comm. = $3400
Then, go in order with your jotted facts to withdraw the total commission amount. Here's what I mean:
$3400 ← total is more than $3000 = +20% comm.
- $1000 ← the first $1000 = +10% comm.
$2400
- $2000 ← the next $2000 = +15% comm.
$400
Then, add together the commission percentages:
20% + 10% + 15% = 45% comm.
Convert the percentage to a decimal:
45% × 100 = 0.45
And multiply it with the total amount to find the commission amount:
$3400 × 0.45 = $1530

Philip writes 2 pages per hour. How many hours will Philip have to spend writing this week
in order to have written a total of 16 pages?
Answer:
8 hours
Step-by-step explanation:
If he writes 2 pages a hour and needs 16 pages, then you would have to divide 16 by 2 which is 8.
To double check that, you can multiply 8 by 2 which is 16.
You answer is 5 hours.
Answer:
8 hours.
Step-by-step explanation: We must Multiply! 2x1=1 2x2=4 2x3=6 2x4=8 2x5=10 2x6=12 2x7=14 2x8=16! We could also divide as well ! 16 divided by 2= 8! We have a grand total of 8 Hours! I Hope this was helpful!

A new vehicle is worth $2500. If it depreciates records in value 12% per year, after 6 years what will it be worth
Answer:
Step-by-step explanation:
2500 - 12%
12% of 2500 = 300
2500 - 300 = 2200
12% of 2200 = 264
2200-264=1936

hopefully this helps you! I'm not too sure but sure enough :)
steps:
1. The answer is none of the above because if you multiply for example 51 x 10 8 it'd be 51 x 80 which is not the answer because 51 x 80 is 4080 which is not 510 000 000.
2. The answer is none of the above because if you divide 0.0763/1.85+4.7x8 it would equal 37.6 which unfortunately isn't an answer above.
3. Finally the answer for this one is B because if you have 8/9 - 5/7 it would equal 11/63 I subtracted 8 and 9 and made sure the bottom numbers were the same, and I simplified.
hopefully THIS helps you?

School fees for a popular high school have been increasing by 9.5% per year. When Antoinette started the school, the annual fees were $6230. By the time Antoinette leaves the school 8 years later, how much have her parents paid in school fees in total? Give your answer to the nearest $100.
Answer:
Antoinette's parents paid $ 70000 by the time she left the school.
Step-by-step explanation:
Antoinette's parents paid at the beginning ([tex]t = 0[/tex]) $ 6230, and each year paid annual fees including increases seven times. ([tex]0 <t \leq 7[/tex]) We find that annual fee paid at a given year is represented by the following formula:
[tex]C(t) = C_{o}\cdot \left(1+\frac{r}{100} \right)^{t}[/tex]
Where:
[tex]C_{o}[/tex] - Initial annual fees, measured in US dollars.
[tex]C(t)[/tex] - Current annual fees, measured in US dollars.
[tex]r[/tex] - Yearly increase rate, dimensionless.
If we know that [tex]C_{o} = \$\,6230[/tex] and [tex]r =9.5[/tex], first 8 annual fees paid by Antoinette's parents are:
[tex]C(0) = \$\,6230[/tex]
[tex]C(1) =\$\,6821.85[/tex]
[tex]C(2) = \$\,7469.93[/tex]
[tex]C(3) = \$\,8179.57[/tex]
[tex]C(4) = \$\,8956.63[/tex]
[tex]C(5) = \$\,9807.51[/tex]
[tex]C(6) = \$\,10739.22[/tex]
[tex]C(7) = \$\,11759.45[/tex]
Now, we sum each yearly fees to determine the total paid by Antoinette's parents when she leaves the school at the end of the 8th year.
[tex]C_{T} = C(0) +C(1)+C(2) + C(3)+C(4)+C(5)+C(6)+C(7)[/tex]
[tex]C_{T} = \$\,6230+\$\,6821.85+\$\,7469.93+\$\,8179.57+\$\,8956.63+\$\,9807.51+\$\,10739.22+\$\,11759.45[/tex]
[tex]C_{T} = \$\,69964.16[/tex]
Antoinette's parents paid $ 70000 by the time she left the school.
3. During last season, Fairfield Farms sold strawberries as follows: 800 boxes at $1.25/box in the early part of the season; 1600 boxes at $0.90/box and 2000 boxes at $0.75/box at the height of the season, and 600 boxes at $1.10/box during the late season. a) What was the average price charged? (b) What was the average price per box?
a)
Average price charged :
[tex]P=\dfrac{1.25+0.90+0.75+1.10}{4}\\\\P=\$1[/tex]
b)
Total income, T =$ 800×1.25 + 1600×0.90 + 2000×0.75 + 600×1.10
T = $4600 .
Total number of box, n = 800 + 1600 + 2000 + 600 = 5000.
Average price per box, [tex]A=\dfrac{4600}{5000}=\$0.92/box[/tex] .
Hence, this is the required solution.
