Answer:
x = 4
Step-by-step explanation:
2(4x + 3) = 10x - 2
2 × 4x + 2 × 3 = 10x - 2
8x + 6 = 10x - 2
8x - 10x = - 6 - 2
- 2x = - 8
2x = 8
x = 8/2
x = 4
-TheUnknownScientist
Answer:
x= 4
Step-by-step explanation:
we open brackets first
2(4x + 3) = 10x - 2
8x+6=10x-2
transpose
6+2= 10x-8x
8= 2x
x= 8/2
x= 4

Which one one of the gradient of the line shown above ?
look at the graph help me !!!
9514 1404 393
Answer:
A 3/2
Step-by-step explanation:
The graph crosses the y-axis at (0, -3) and the x-axis at (2, 0). Using the slope formula, we can find the slope of the line to be ...
m = (y2 -y1)/(x2 -x1)
m = (0 -(-3))/(2 -0)
m = 3/2 . . . . matches choice A

What is the sum of the interior angles of a polygon that has 10 sides?
Answer:
Hope this helps :D
So, the sum of the interior angles of a decagon is 1440 degrees. All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles, we know that the sum of all the angles is 1440 degrees (from above)... And there are ten angles
Answer:
I think the answer is 1440
Step-by-step explanation:
A polygon with 10 sides a decagon ,and the sum of the interior angles is 1440 degrees.
Quadratic applications??
Answer:
Step-by-step explanation:
2 l + 2w = 34 ⇔ l + w = 17 ⇒ l = 17 - w ..... (1)
l w = 66 ..... (2)
(1) ----> (2)
(17 - w) w = 66
w² - 17w + 66 = 0 ⇔ (w - 6)(w - 11) = 0
w = 6 cm
l = 11 cm

How do you do these questions?
Part (a)
The equilibrium price occurs at the intersection of the supply and demand curves. See the diagram below to see how this looks. Ignore the red line and green lines for now. Those will apply for part (b).
If the price was below equilibrium, then we would have a shortage and it would lead to a pressure to push prices upward. If the price was below equilibrium, then there would be a surplus or oversupply, leading to a downward pressure in prices. So inevitably the price lands on the equilibrium if given enough time and there are no external forces acting on the market.
==============================================================
Part (b)
Let's say we have two people labeled person A and person B. If person A gets a higher education, while person B does not, then person A is likely to earn more money. Person B will see this and want to may want to earn more money as well, so that makes their demand for higher education go up. While of course this rule doesn't work for everyone, in general we'll have enough people to effectively push the demand curve to the right while the supply curve remains where it is. Check out the diagram below to see what I mean.
==============================================================
Part (c)
Refer to the diagram in part (b). We have a new demand curve which intersects the supply curve to produce a new equilibrium point with price P1 and quantity Q1. So effectively the tuition has gone up due to higher demand.
==============================================================
Part (d)
If a government provides a subsidy, then this would lower the cost of education to provide people with more opportunities to improve their earning potential. The subsidy would provide a portion of the tuition which gives the illusion of the tuition price being lowered. In a way it's like getting a grant from the government to then pay that money toward your tuition.

If H(x) = [tex]\sqrt{r(x)}[/tex],
and r(3) = 9,
and r'(3) = -1,
What is H'(3)?
I used the chain rule but for some reason I'm still getting the wrong answer.
You should find the answer from the answers you wrote
Step-by-step explanation:
u should find the x from the answers you wrote like the r'(3) = -1
then from this answer u should think about the h'(3)' answer

What is the solution to the system of equations? O (-6,-) O (-2, 6) O (6,2) O (-2,-6)
Answer:
Option (1)
Step-by-step explanation:
System of equations is represented by two straight lines on a graph.
And solution of the system of equations is the point of intersection of these lines.
From the graph attached, two straight lines represent the system of equations.
And the point of intersection of these lines is the solution.
Therefore, solution of the system of equations will be (-6, -2).
Option (1) will be the correct option.

Answer:
B 16%
Step-by-step explanation:
You add all of the numbers up you get 25 and then you multiply it by four then multiply red shirts by 4
Answer:
B. 16%
Step-by-step explanation:
First, figure out the total number of people in Emily's class. To get the total amount of people in the class, add all of the numbers together.
5+6+4+3+5+2=25
We need the percentage of people who wore a red shirt. So, we need to find the whole first (100%). To get the whole to 100%, we need to find out what to multiply by 25 to get 100. This is easy because we automatically know 25x4=100.
Because we multiplied 4 by 25, now we have to multiply 4 by the number of students who wore a red shirt. 4 people wore a red shirt, so...
4x4=16
When you put 16 over 100, it looks like this: 16/100. Percentages are out of 100, so 16% of the class wore red shirts.
Hope this helps!! Have a great day :3
