Step-by-step explanation:
All you're really doing for expressions like this are dividing the whole number into the number with the variable. for example, i took 5 and divided it into 15x which gave me 3 so the X will equal 3. Hope I helped

find an equation for the line below
Answer:
Look at the dotted points on the line in your graph. check their coordinates, for your ease i am attaching a picture, please have a look.
so the two coordinates we have is : ( 3 , 1 ) , (- 1 , - 5)
Now let's find the gradient from these two coordinates.
[tex]\frac{y_{1}-y_{2} }{x_{1} -x_{2} }\\\\=\frac{1-(-5)}{3-(-1)}\\\\=\frac{6}{4}\\= 1.5[/tex]
Now we use the equation of a straight line and here , you can use any of the coordinates. For my ease, I am using the first one:
[tex]y-y_{1} = m (x-x_{1})\\ y- 1 = \frac{3}{2} (x-3)\\\\2y-2 = 3x - 9\\2y - 3x = -7[/tex]

One key thing to note about a reflection is that side lengths and angle measures will always remain the same on the reflected figure. With that in mind, let's note the side lengths in both the original and reflected figures.
[tex]AB=\\BC=20\\CD=30\\AD=[/tex]
[tex]A'B'=22\\B'C'=\\C'D'=\\A'D'=32[/tex]
Remember, since side lengths are the same, let's fill in the missing values with the values of the side lengths given in each of the figures:
[tex]AB=22\\BC=20\\CD=30\\AD=32[/tex]
[tex]A'B'=22\\B'C'=20\\C'D'=30\\A'D'=32[/tex]
See? Notice how the values are the same! To find the perimeter ([tex]P[/tex]) of a quadrilateral, we have to add each side length:
[tex]P=22+20+30+32[/tex]
Solve:
[tex]P=104[/tex]
joel and todd are at a pool. Joel dives in and touches the bottom of the pool, 12 feet below the surface of the water. Todd is standing on a diving platform 3 feet above the surface, waiting for his turn. What is the vertical distance between joel's hand and todd's feet?
Answer:
15 feet
Step-by-step explanation:
A typical diagram has been shown.
Joel's hand touches the bottom of the pool, point A as shown, 12 feet below the surface of the water.
Todd's foot is at the diving platform, at point B as shown, 3 feet above the surface of the water.
Let S be the point on the surface of the water.
So, the vertical distance between Joel's hand and todd's feet
=AS+SB
=12+3
=15 feet.
Cody started a fire in a field. The fire was expanding outward in all directions forming a larger and larger circle. The radius of the circular fire was 10 feet and was increasing at 2 feet/minute when Cody called the fire department. How many minutes will it take from the time Cody called the fire department until the area of the circular fire is 45401 square feet? Type your answer to the nearest hundredth (2 decimal places).
Answer:
55.10minStep-by-step explanation:
This problem is on the mensuration of flat shapes.
given that the initial radius before Cody alerted the fire department is
10 ft
Then we can calculate the area of the fire as
Area= πr^2
Area=3.142*(10)^2
Area=3.142*100
Area=314.2ft^2
Also, given that the area of the circular fire has grown to 45401 square feet
let us solve for the radius first, then we can calculate the time taken since the radius was increasing by 2 ft/min
let the radius of the large fire be R
45401=πR^2
R^2=45401/3.142
R^2=14449.714
square both sides we have
R=√14449.714
R=120.2ft
The difference between the radius of the initial fire and the large fire is
R-r=120.2-10
=110.2ft
Hence the time taken can be calculated as
time= 110.2/2
time=55.10min

In two or more complete sentences, describe how to find the interval(s) where the function is decreasing and how interval notation is used to express the interval(s). In your final answer, include the interval in which the function is decreasing.
Answer:
The function is increasing when the slope is greater than zero and decreasing when the slope is less than zero. Slope is (y2-y1)/(x2-x1) or the change in y divided by the change in x.
In this case the function is decreasing when x=[-8,-5) and when x=[4,8)
So in interval notation: x=[-8,-5)U[4,8)

Complete Question
Carson is a high school student with two part-time jobs. He earns $6 per hour for babysitting, and he earns $8 per hour doing clerical work for his father's business. His goal is to earn at least $96 a week, but because of school, he does not want to work more than 15 hours each week. Let b represent the number of hours Carson works in one week at the babysitting job, and let c represent the number of hours Carson works in one week at his father's business. Which inequalities represent the constraints on what Carson can earn and the number of hours he can work in one week? Select all that apply.
A) b+c≤15
B) 6b+8c≤15
C) 6b+8c≥15
D) b+c≥96
E) 6b+8c≥96
F) 6b+8c≤96
Answer:
A) b + c ≤ 15
E) 6b + 8c ≥ 96
Step-by-step explanation:
Let b represent the number of hours he can work babysitting
Let c represent the number of hours he can work clerical work
We can derive 2 inequality equations
From the question, we are told:
He does not want to work more than 15 hours each week because of school
This means the maximum he wants to work is 15 hours, meaning he can work less than that. So we used the inequality less than or equal to Hence:
b + c ≤ 15...... Equation 1
He earns$6 per hour for baby sitting,and he earns $8 per hour doing clerical work for his father's business.His goal is to earn atleast $96 a week.
This means $96 is the least amount he wants to earn , meaning he can earn more than that. So we used the inequality greater than or equal to
Hence:
$6 × b +$8 × c ≥ $96
6b + 8c ≥ 96
Therefore, the two inequalities that represent the constraints on what Carson can earn and the number of hours he can work in one week:
A) b + c ≤ 15
E) 6b + 8c ≥ 96
