Answer:
slope = 4
Step-by-step explanation:
recall that for a linear equation in the form:
y = mx + b,
m = slope of line and b is the y-intercept.
In our case, we are given
y = 4x
If we compare this with the general equation above,
we can see that m = 6 and b = 0
hence slope = m = 4
Pleaseee i'm struggling so hard on this Geometry thing, show work please
Answer:
(12x+1)+(5x-3)=117
combine like terms 12x+5x=17x
1+-3= -2
17x-2=117
add 2 to both sides to isolate the variable
17x=119
divide both sides by 17 to further isolate the variable
x=119/17
x=7
answer is x=7
Step-by-step explanation:
add both angles to be the sum of the angle DEF and determine what x must be by the steps above
Answer:
x=7°
Step-by-step explanation:
Form an equation:
12x+1+5x-3=117°
Collect like terms:
Like terms are terms with the same variables and powers.
12x+5x=17x
1-3=-2
put I back into an equation:
17x-2=117°
As we want x, you would have to do inverse operations to 'undo the equation'.
117+2=119°
17x=119°
119÷17=7° (We divide by 17 because when a number is next to a letter, in algebra, it means you times so we have to do the opposite and divide)
So, x=7
Hope this helps :)

Selling frozen yogurt at a fair, you make $565 and use 250 cones. A single-scoop cone cost $2 and a double-scoop cone cost $2.50. How many of each type of cone did you sell?
The seller sold 120 single-scoop cones and 130 double-scoop cones to make $565.
250 cones were used while selling yogurt and made $565.
There are two types of cones:
Single-scoop cone that cost $2.
Double-scoop cone that cost $2.50.
We need to know how many cones of each type were used while selling yogurt that made $565.
This is a system of linear equations problem.We will have to make two linear equations using the given statements and apply the substitution method to get our answer.
Consider,
x = single-scoop cone.
y = double-scoop cone.
Now, we can make two linear equations:
x + y = 250............(A)
2x + 2.50y = 565...............(B)
Apply substitution method.
From (A) we get,
x = 250 - y...............(C)
And putting x = 250 - y in (B) we get,
2 ( 250 - y ) + 2.50y = 565
500 - 2y + 2.50y = 565
0.50y = 565 - 500
0.50y = 65
y = 65 / 0.50
y = 6500 / 50
y = 130
Putting y = 50 in (C) we get,
x = 250 - 130
x = 120
We have,
x = 120 and y = 130
We see that we need 120 single-scoop cones and 130 double-scoop cones to make $565.

Kari bought 3 boxes of cookies to share with a book club. Each box contains 12 cookies. The expression StartFraction 36 over p EndFraction represents the number of cookies that each person, p, can have if the cookies are divided equally. Which evaluations of the expression are correct? Select three options. If p = 5, then each person would get 6 cookies, with 4 cookies left over. If p = 7, then each person would get 5 cookies, with 1 cookie left over. If p = 8, then each person would get 4 cookies, with 3 cookies left over. If p = 10, then each person would get 3 cookies, with 6 cookies left over. If p = 11, then each person would get 3 cookies, with 3 cookies left over.
Answer:
i). If p = 7, then each person would get 5 cookies, with 1 cookie left over.

iii). If p = 11, then each person would get 3 cookies, with 3 cookies left over.
Step-by-step explanation:
First option is wrong because 5 dividing 36 is 7, not 6. It would remain 1, not 4.
Second option is correct because 36 divided by 7 would give you 5 remaining 1.
Third option is correct because 8 dividing 36 is 4, but will remain 4, not 3.
Fourth option is correct because 36 divided by 10 is 3, then will remain 6.
Fifth option is correct because 36 divided by 11 is 3, remaining 3.

It's not a typo that 0 is written twice.
==============================================================
Explanation:
This is considered a step function because it resembles steps or a staircase. The vertical pieces aren't drawn to allow it to remain a function (or else it fails the vertical line test). Also there should be open holes at each left endpoint.
Recall that any horizontal line has a slope of 0 due to the fact that the rise is 0
slope = rise/run
The rise takes care of the vertical change in position. But if the line doesn't go up or down, then rise = 0 leads to slope = 0.
In short, the slope of each horizontal portion is 0. It doesn't matter which sub-section you focus on.
This is why you'll type 0 into the first two boxes.
------------------
As for the remaining two boxes, you'll be looking where the graph is the highest and the lowest to determine the max and min y values respectively.
We see that y peaks at y = 4 at the very top. So you'll type 4 into the third box.
Furthermore, we see that the lowest part of the graph is when y = -3. Therefore, this is the minimum aka smallest y value and you'll type -3 into the fourth box.
An angle measures 75.2° more than the measure of its complementary angle. What is the measure of each angle?
Answer:
x = complement
x + 5.2 = first angle (5.2 more than complement)
measure of two complementary angles add up to 90.
x + x+ 5.2 = 90
2x = 84.8
x = 42.4
other angle = x + 5.2 = 42.4 + 5.2 = 47.6

Carlos pagó una cuenta de $300 con billetes de $5 y de $10. En total empleó 45 billetes para hacer el pago, ¿cuántos billetes de cada valor utilizó
Answer:
30 billetes de 5 dólares y 15 billetes de 10 dólares
Step-by-step explanation:
I don't speak spanish but take it in school, so I understand the question but cannot respond back in spanish.
Letting x = $5 bills and y = $10 bills,
x + y = 45
5x + 10y = 300
Solving the system by substitution,
y = -x + 45
5x + 10(-x+45) = 300
5x - 10x + 450 = 300
-5x = -150
x = 30
Substituting the x-value back into the equation,
x + y = 45
30 + y = 45
y = 15

PLEASE HELP! 20 POINTS 1) A ball is thrown starting at a time of 0 and a height of 2 meters. The height of the ball follows the function H(t)=−4.9t2+25t+2. What is the height of the ball at each second from 0 to 5? (I'll put a picture of the graph.) 2) Which expression could represent the height of a soccer ball as it is in the air after being kicked? (This is part 2 to question 1) A. −16t+9 B. −16t2+4t3 C. 9t2+25t D. −16t2+25t+1
Answer:
a or b
Step-by-step explanation:
it just looks like b or a
H(t) = -4.9t^2 + 25t + 2
Height is a function of time
plug in 0, 1,2,3,4, and 5 to find the height at 0, 1,2,3,4, and 5 seconds.
at t = 0
H(0) = -4.9(0)^2+25(0) + 2 = 2 meters
Repeat for T=1,2,3,4 and 5
Notice the ball peaks around t = 3 seconds and starts to descend.
H(1) = (-4.9)(1^2) + 25(1) + 2 = 22.1 meters
H(2) = (-4.9)(2^2)+25(2)+2=32.4 meters
H(3) = 32.9 meters
H(4) = 23.6 meters
H(5) = 4.5 meters

Gabby is touring New York City with her family. They want to visit the Empire State Building, Central Park, and Times Square before their dinner reservations at 8:25 P.M. They want to spend 1 hour and 10 minutes at the Empire State Building, 2 hours and 50 minutes in Central Park, and 1 hour in Times Square. What is the latest time Gabby's family can start their tour in order to make it to dinner on time?
Answer:
3:25 pm
Step-by-step explanation:
How much time do they need for tours
Empire State Building : 1 hour 10 minutes
Central Park 2 hour 50 minutes
Times Square 1 hour
-------------------------------
4 hours 60 minutes
but 60 minutes = 1 hour so subtract 60 minutes and add 1 hour
4 hours 60 minutes
+1 -60
--------------------------------
5 hours
They need 5 hours for the tours
We have to be at dinner at 8:25 so we need to start 5 hours earlier
8:25
- 5
------------------
3:25
We can start no later than 3:25 pm
Answer:
3.25
Step-by-step explanation:
First convert into minutes
1 hour = 60 minutes
Empire state building:
60 + 10 = 70
Central park:
60 + 60 + 50 = 170
Times square:
60
Now add all minutes together.
70 + 170 + 60 = 300 minutes.
Convert into hours:
300 / 60 = 5 hours.
8 - 5 = 3
So, Gabby's family can start their tour at 3:25 at most to get to dinner on time.

Ahmad has some files.
He gave 3/5 of the files and had 14 files left.
How many files did he have at first?
Answer:
The answer is 35Step-by-step explanation:
Let the number of files he had be x
He gave 3/5 of the files
That's
3/5x
After that he still had 14 files left which means when we subtract 14 from the original files we should get 3/5 of the original files
So we subtract 14 from the original number of files
That's
x - 14
We equate the two statements
that's
[tex] \frac{3}{5} x = x - 14[/tex]
Multiply through by 5
[tex]5 \times \frac{3}{5} x = 5x - 70[/tex]
We have
3x = 5x - 70
3x - 5x = 70
-2x = - 70
Divide both sides by -2
We have the final answer as
x = 35Therefore he had 35 files at first
