Answer:
Slope = -1/4
Y-intercept = 50
Step-by-step explanation:
Change in y/ change in x = slope
75/-100 = -1/4
For y, the numbers decrease 25 each time so the change in y is -25.
For x, the numbers increase 100 each time so the change in x would be 100.
The fraction you have left is -25/100
Now, you simplify -25/100 and you get -1/4.
The y-intercept is 50 because x is 0 at the same time in the chart.

Answer:
x = 3.5
Step-by-step explanation:
[tex] \triangle DEF \sim \triangle XYZ\\\\
\therefore \frac{DE}{XY} =\frac{DF}{XZ} \\\\
\therefore \frac{5}{7.5} =\frac{7}{3x} \\\\
\therefore 3x = \frac{7.5\times 7}{5} \\\\
\therefore x = \frac{7.5\times 7}{3\times 5} \\\\
\therefore x = \frac{52.5\times 7}{15} \\\\
\therefore x = 3.5[/tex]
Step-by-step explanation:

How long does it take to travel 100km at a speed of 80 km/h?
Answers
You can kind of tell that, because the units of speed is km/h ( or m/s, or miles/hour — depending on the situation).
Now if you apply your algebra skills, you might discover that
time = distance/speed
Plug in the data:
time = 100 km / (80 km/h)
After application of algebra skills again you can see that the units will simplify to simply h.
time = 1.25 h

Answers
Answer:
a. Multiplication property of equality
b. Distributive property
c. addition property of equality
Step-by-step explanation:
The first one is wrong because you are multiplying the 2 on both sides to make it equal. There was nothing that they substituted for.
The second one will be the distributive property not the subtraction property of equality. They distributed the 2 into the [tex]\frac{1}{2}x[/tex] and the [tex]-5[/tex]. So that clears up that this step was the distributive property.
This one will be the addition property of equality because when you have a negative number you do the inverse so they added the 10 on both sides. Therefore it's the addition property of equality.

Jenny planned to solve 2/3 of homework
On Saturday she solved 28 problems, which is 7/8 of the planned number

Jenny's homework was:
32 : 2/3 = 32 * 3/2 = 48 problems
Back in ye olden days, cell phone companies charged for texting. A cell phone company charges 10 cents per text message if a customer sends up to 100 messages per month, 8 cents for 101-200 messages, and 6 cents for 201-300 messages. If today is the last day of the month, and you've sent 200 texts, is it worth it to send 1 more text message?
Answers
Answer: It is worth it.
Step-by-step explanation:
If a customer sends 101 - 200 texts in a month, they get charged 8 cents per text.
If they send 201 - 300, they get charged 6 cents per month.
If you have sent 200 texts, your charge for the month will therefore be:
= 200 * 8
= $16.00
If you send the 201th text, you will be charged 6 cents per text. Total charge would be:
= 201 * 6
= $12.06
If you send 1 more text, it will be worth it because you will save:
= 16 - 12.06
= $3.94
Carlos wants to rent a car for the particular car you on gentle rental charges 185 per week plus $0.25 per mile driven rental charges a flat fee of 275 per week what is the number of miles driven so that rented from dental rental cause carlos less than renting from rental giant
Answers
Answer:
The indifference point is 360 miles.
Step-by-step explanation:
Giving the following information:
Rental 1:
Total cost= 185 + 0.25*x
x= miles driven
Rental 2:
Total cost= $275
Now, we need to equal both formulas and isolate x:
185 + 0.25x = 275
0.25x = 90
x= 90/0.25
x= 360
The indifference point is 360 miles.

Step-by-step explanation:
Given: Deborah bought a computer for [tex]25\%[/tex] off the list price.
The list price is [tex]\$2,428[/tex].
To find: The amount Deborah spent on the computer.
Solution: We have,
List price of the computer [tex]=\$2,428[/tex].
Deborah bought the computer for [tex]25\%[/tex] off the list price.
The amount Deborah spent on the computer [tex]=25\% \times 2,428[/tex]
[tex]=\frac{25}{100}\times2428=\frac{2428}{4} =\$ 607[/tex].
So, Deborah spent [tex]\$607[/tex] on the computer.
Hence, option A is correct.
