Answer:
y-32=3(x-5)
Step-by-step explanation:
The swimming pool is being drained at a constant rate of 3 inches per hour, therefore:
The rate of change, Slope, m=3 inches per hourIf the depth of the water after 5 hours is 32 inches.
The depth is the dependent variable(as its values varies with time) while the time is the independent variable, we can write this as a pair (x,y)=(5, 32).
The point slope form of the equation of a line is of the form: [tex]y-y_1=m(x-x_1)\\(x_1,y_1)=(5,32), m=3\\$Substituting these values, we obtain:\\y-32=3(x-5)\\This is the equation of the function in point slope form.[/tex]
You are driving to visit a friend in another state who lives 440 miles away. You are driving 55 miles per hour and have already driven 275 miles. Write and solve an equation to find how much longer in hours you must drive to reach your destination. A. 55h + 275 = 440 ; h=3 B.55h - 275 = 440 ; h= 13 C.440h -275 = 55 ; h =0.75 D. 55h +275h = 440 ; h=1.3
Answer:
A. 55h + 275 = 440; h=3
Step-by-step explanation:
Since all answer choices have a different H= , finding how many hours you have left to drive will give you the right answer.
You've already driven 275 miles in your 440 mile trio so you can subtract the 275 to find out how much you will still need to drive.
440 - 275 = 165
You already know that you are driving at 55 mph so divide 165 by 55 and the answer is three.
Option A was the only answer choice which listed h=3 so that is the correct answer.

The price of a stock decreased by 60 cents one week, decreased 10 cents the next week, and decreased another 20 cents the following week. What is the average change in the price of the stock over the three weeks? A. –270 cents per week B. –90 cents per week C. –87 cents per week D. –30 cents per week
Answer:
D
Step-by-step explanation:
In 3 weeks the stock decreased 60 + 10 + 20 = 90 cents so it decreased about 90 / 3 = 30 cents per week so it is D.
Answer:
The answer is D
Step-by-step explanation:

Consider the equation y=-x^2-7x+12
Answer:
y = (x + 4)(x + 3)
Step-by-step explanation:
y = x ^2 + 7x + 12
The two numbers must add up to 7 and has a product of 12, and since the equation is all positive, then the two numbers are positive too.
So y = (x + 4)(x + 3) is the answer.
Check:
y = (x + 4)(x + 3)
y = x(x + 3) + 4(x + 3) distributive property
y = x^2 + 3x + 4x + 12
y = x^2 + 7x + 12
Even the measure ofAngle six is 62 what is the measure of angle five
∠5 = 118
Step-by-step explanation:
If you look closely at this image, you can see that ∠6 and ∠5 together will be equal to line c.
A straight line is equal to 180 so if we do...
[tex]180-62[/tex]
= 118.
∠5 will be equal to 118.
If we go even further, because vertical angles are congruent...
∠7 = 62
∠8 = 118
Answer:
[tex] m \angle \: 6 = 118 \degree[/tex]
Step-by-step explanation:
[tex]m \angle \: 5 + m \angle \: 6 = 180 \degree.. (straight \: line \: \angle s) \\ \because \: m \angle \: 5 = 62 \degree \\ \therefore \: 62 \degree+ m \angle \: 6 = 180 \degree \\ \therefore \: m \angle \: 6 = 180 \degree - 62 \degree \\ \huge \red{ \boxed{\therefore \: m \angle \: 6 = 118 \degree}}[/tex]
Ok so I’m in high school and I forgot everything I learned in 6-7th grade so what is 14/2 + 12/6 I got 54/6 but I don’t know what to do to get it into simplest form btw I’m very dumb so please explain it like you would to a 4yr old
Answer:9
Step-by-step explanation:
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator. Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1. (14/2 x 3/3)+(12/6 x 1/1). Complete the multiplication and the equation becomes 42/6+12/6. The two fractions now have like denominators so you can add the numerators. 42+12/6=54/6. Divide 54 by 6 and get 9. hope this helps :)
Convert 11.7 cm3 into ml
Answer:
11.7
Step-by-step explanation:

amanda has a board that is 7 feet long. how many 1/4 foot sections can she cut from this board
Answer:
28
Step-by-step explanation: You need to divide 7 by 1/4. Whenever you divide fractions you keep the first number as it is, change the sign to multiplication and write the reciprocal of the second fraction which is you have to flip the fraction. It is going to be 7 times 4/1. Which is 28/1 which is 28.
1 3/4 x 4 1/6 whats answer
Answer:
7 7/24
Step-by-step explanation:
first put the wholes inside the fraction:
[tex]1 \frac34 = \frac44 + \frac34 = \frac74[/tex]
[tex]4 \frac16 = \frac{24}{6} + \frac16 = \frac{25}{6}[/tex]
Then multiply numerator times numerator, denominator times denominator and take out wholes again:
[tex]\frac74 \times \frac{25}{6} = \frac{7 \times 25}{4 \times 6} = \frac{175}{24} = 7 \frac{7}{24}[/tex]

Determine whether the system of linear equations has one solution infinitely many solutions or no solution explain your reasoning. y=3x+5 and y=3x-5
Answer: The equations have no solution because no solution graphs have the same slopes but difference y- intercepts.And by looking at the equations they both have same slope as 3 but different y-intercepts 5 and -5.
Step-by-step explanation:
y= 3x + 5
y = 3x- 5
3x + 5 = 3x -5
-3x -3x

The student council at Clarksville High School is making T-shirts to sell for a fundraiser, at a price of $10 apiece. The costs, meanwhile, are $8 per shirt, plus a setup fee of $98. Selling a certain number of shirts will allow the student council to cover their costs. What will the costs be? How many shirts must be sold?
Answer:
Costs are $490
49 shirts are sold
Step-by-step explanation:
98 + 8x = 10x
98 = 2x
49 = x

If f(x)= 3x^2-2x+4.and g(x)= 5x^2 +6x -8find(f-g)(x)
Answer:
-2x^2-8x+12
Step-by-step explanation:
f(x)= 3x^2-2x+4
g(x)= 5x^2 +6x -8
(f-g)(x) = 3x^2-2x+4-(5x^2 +6x -8)
Distribute the minus sign
(f-g)(x) = 3x^2-2x+4-5x^2 -6x +8
Combine like terms
-2x^2-8x+12
Suppose that for some function g,
g(x+4)= 7x + 2. Find g(-3).
