1 joule per second is one watt.
What is the slope of the line that passes through the points (-2, -1)
and (2, -3)? Write your answer in simplest form.
Plug this into the formula y2 - y1 / x2 - x1
-2 = x1, x2 = 2, y1 = -1, y2 = -3
-3 - (-1) / 2 - (-2)
-2 / 4
-1/2
The slope is -1/2.

A golf ball is hit with an initial velocity of 80 feet per second. H= -16t^2 + 80t.
1) When will the ball reach 48ft?
2) When will the ball reach 110ft?
9514 1404 393
Answer:
t = 0.697 secondsnever (the maximum height is 100 ft)Step-by-step explanation:
A graphing calculator provides a nice solution to this question.
__
1) Put 48 ft in for H and solve for t:
48 = -16t^2 +80t
-3 = t^2 -5t
3.25 = t^2 -5t +6.25 = (t -2.5)^2
t = 2.5 ±√3.25
The ball will first reach 48 feet at t = 2.5 -√3.25 ≈ 0.697224 seconds.
__
2) The equation tells us the maximum height occurs at t=2.5 seconds. That height is ...
H = -16(2.5^2) +80(2.5) = 100
The maximum height is 100 feet. The ball will never reach 110 feet.
Andrea ordered a pizza for dinner. She ate 1/4 of the pizza. Her brother ate 35% of the pizza. Her mom ate .10 of the pizza. How much pizza is left?
Answer: 0.3, 30%, or 3/10
Step-by-step explanation:
Andrea ate 1/4 of the pizza.
1/4 = 0.25
Her brother ate 35% of the pizza.
35% = 0.35
Her mom at 0.10 of the pizza.
1 - 0.25 - 0.35 - 0.10 = 0.3 of the pizza
0.3 = 30% = 3/10

The sports store made $564 from selling pool rafts this week (Monday-Friday). Of that amount, it made $132.56 on Monday and $107.38 on Tuesday. IT made an equal amount of money on Wednesday, Thursday, and Friday. How much money did the store make from selling pool rafts on Friday?
Answer:
Amount made from selling pool rafts on Friday is equal to $108.02
Step-by-step explanation:
Total amount made from selling pool rafts = $564
Amount made from selling pool rafts on Monday = $132.56
Amount made from selling pool rafts on Tuesday = $107.38
Let amount made on each of the days - Wednesday, Thursday, and Friday be equal to $x.
Therefore,
[tex]132.56+107.38+x+x+x=564\\239.94+3x=564\\3x=564-239.94\\3x=324.06\\x=\frac{324.06}{3}\\ x=$108.02[/tex]
So,
amount made from selling pool rafts on Friday is equal to $108.02

2x-9x+17=-4
I have a answer but I’m not sure if I’m correct so I just want to double check.
Answer: x = 3
Step-by-step explanation: Simplify both sides
2x - 9x + 17 = -4
2x + - 9x + 17 = -4
Combine like terms
(2x + -9x) (17) = -4
-7x + 17 = -4
Subtract 17 from both sides
-7x + 17 - 17 = -4 - 17
-7x = -21
Divide both sides by -7
-7x/-7 = -21/-7
x = 3
Answer:
x=3
Step-by-step explanation:
subtract 2x and 9x ( 2x-9x= -7x)subtract 17 and -4 ( -4 -17= -21)divide -21 and -7 ( -21 / -7= -3)x=3John's birthday is this saturday, in buying materials for the party Vicki notices that plates come in packs of 12, cups come in packs of 10, and utensils come in packs of 8 sets. If Vicki wants to have no left overs, how many packs of utensils should she buy?
Answer:
Step-by-step explanation:
So, Vicki wants no left overs whatsoever, which means we have to get all three items to the same number. We first look at 10. We know that 10 will always have a 0 in the one's place, meaning that 8 and 12 have to be multiplied by 5, 10, 15, 20, etc., but they do not need to be multiplied by the same number.
Let's take 8 first. 8 can possibly go up to 40, 80, 120, 160, 200, etc.
Then 12. 12 can possibly go up to 60, 120, 180, 220, 280, etc.
We can see that both numbers have 120 in common, so we shall use that.
We know that we can get 10 to 120 by multiplying 10 by 12, meaning Vicki buys 12 packs of cups.
We know that we can get 12 to 120 by multiplying 12 by 10, meaning Vicki buys 10 packs of plates.
And finally, we know that we can get 8 to 120 by multiplying 8 by 15, meaning Vicki buys 15 packs of utensils.
So, since the question is asking for utensils only, we should say that Vicki buys 15 packs of utensils.

How do I solve 5(1 − x) + 2(x + 3) ?
Answer:
11-3x
Step-by-step explanation:
1) Multiply 5(1-x). To do this, you multiply 5 by both x and 1. You should get 5-5x.
1) Next, multiply 2(x+3). You should get 2x+6.
3) Finally, add like terms. Add 2x and -5x together and add 6 and 5 together. You should get -3x and 11.
The answer is 11-3x.

A sequence can be generated by using an=an−1+9, where a1=−5 and n is a whole number greater than 1. What are the first four terms in the sequence?
A.−5, 4, 13, 22
B.9, 4, −1, −6
C.−5, −45, −405, −3645
D. 9, −45, 225, −1125
Answer:
B.9, 4, −1, −6
Step-by-step explanation:
A sequence can be generated by using an=an−1+9, where a1=−5 and n is a whole number greater than 1. What are the first four terms in the sequence?
A.−5, 4, 13, 22
B.9, 4, −1, −6
C.−5, −45, −405, −3645
D. 9, −45, 225, −1125
From the above question,
A sequence can be generated by using an=a(n−1)+9, where a1=−5
The formula = an = a1 + (n - 1)d
a1 = First term
d = common difference = 9
We are to find the first 5 terms
First term = a1 =
an=an−1+9, where a1=−5
The formula =
a1 = -5 (1 - 1) + 9
= -5(0) 9
= -9
Second term = a2 =
an=an−1+9, where a1=−5
The formula = an = a1 (n - 1) + d
a2 = -5(2 - 1) + 9
= -5(1)+ 9
= -5 + 9
= 4
Third term = a3 =
an=an−1+9, where a1=−5
The formula = an = a1(n - 1) + d
a3 = -5(3 - 1)9
= -5(2) + 9
= -10+ 9
= -1
Fourth term = a2 =
an=an−1+9, where a1=−5
The formula = an = a1(n - 1) + d
a4 = -5(4 - 1)9
= -5(3) +9
= -15 +9
= -6

Solve for x: 5 − (x + 5) > −2(x + 4)
x > −8
x −18
x < −18
PLS PLS PLS HURRY I GIVE BRAINLIEST
Answer:
The answer is
[tex] \huge x > - 8[/tex]
Step-by-step explanation:
[tex]5 − (x + 5) > −2(x + 4)[/tex]
First of all expand the terms in the bracket
That's
[tex]5 - x - 5 > - 2x - 8 \\ - x > - 2x - 8[/tex]
Add 2x to both sides
[tex] - x + 2x > 2x - 2x - 8 \\ x > - 8[/tex]
We have the final answer as
[tex]x > - 8 [/tex]
Hope this helps you
Answer:
x > -8
Step-by-step explanation:
5 − (x + 5) > −2(x + 4)
Simplify both sides first:
5 - x - 5 > -2x - 8
-x > -2x -8
Now isolate the variable:
-x > -2x -8
+2x +2x
x > -8
cylindrical container has a height of 24 inches. Currently, the container is filled with water to a height of 18 inches. A leaky faucet drips into the container, causing the height of the water in the container to increase by 2 inches per hour. The equation below can be used to find t, the number of hours it would take to fill the container.
18 + ?t = 24
What number should be the coefficient of t?
Answer:6
Step-by-step explanation:
Answer:
6 would be the coefficient
Step-by-step explanation:
So what we are trying to do is solve for t.
18 + t = 24
-18 -18
t = 6
It would take 6 hours to fill the container.
Hope that helps and have a great day!

how do you solve inequalities and how do you graph them?
Answer:
Graph a Linear Inequality
Step-by-step explanation:
Rearrange the equation so "y" is on the left and everything else on the right.
Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).
