Step-by-step explanation:
(y - y1)/(y2 - y1) = (x - x1)/(x2 - x1)
(y + 7)/(-4 + 7) = (x + 8)/(-4 + 8)
(y + 7)/3 = (x + 8)/4
4(y + 7) = 3(x + 8)
4y + 28 = 3x + 24
4y = 3x + 24 - 28
4y = 3x - 4
y = 3x/4 - 1
33y + 16; y = 3
PLSSS HELP MEE
Answer:
115
Step-by-step explanation:
y = 3
33y + 16
So since we know what y equals, we replace y in the equation to find our answer
33(3) + 16
33 times 3
99 + 16
115

Ned calculated 17 divided by 4= 4.25. Use estimation to see if his answer is reasonable. How can you check his exact answer?
Answer:
you can use estimation by saying that 4 * 4 = 16 and 4 * 5 = 20
therefore your number has to be less that 5 but slightly greater than 4.
you can check his exact answer by doing division or checking it on a calculator.

Frankie and Gus swam for 10 minutes. When the time was up, Frankie had completed 10 7/10 laps and Gus 10 4/5 had completed laps. Frankie wrote the inequality 10 7/10 > 10 4/5 to show who swam the longest distance. Was he correct? Explain your answer by describing where the numbers would be positioned on a number line.

Answer:
No. He was incorrect.
Step-by-step explanation:
10 4/5 = 10 8/10.
=> 10 7/10 < 10 8/10
The above inequality is correct.
Hoped this helped.
The inequality written by Frankie is incorrect. so 10 7/10 < 10 8/10 inequality is correct.
What is a solution set to an inequality or an equation?If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solutions to that equation or inequality.
We have been given that Frankie and Gus swam for 10 minutes. When the time was up; Frankie completed 10 7/10 laps and Gus 10 4/5 had completed laps.
Since Frankie wrote the inequality to show who swam the longest distance as;
10 7/10 > 10 4/5
We can see that the fraction are;
10 4/5 = 10 8/10.
Thus, the inequality written by Frankie is incorrect.
So, 10 7/10 < 10 8/10
This inequality is correct.

solve the system y=6x=5 y=3x-23
Answer:
False θ·θ.................
Answer:
x = -28/3
y = -51
Step-by-step explanation:
Let's solve for X first
6x + 5 = 3x - 23
-3x -5 (like terms)
3x = -28
/3 /3 (divide by 3)
x = -28/3

Step-by-step explanation:
let x be the unknown angle
1. 32+98+x=180(sum of angles in a ∆ equal to 180°)
130+x=180
x=180-130
x=50°
2. 25+90+x=180
115+x=180
x=180-115

The increasing annual cost (including tuition, room, board, books, and fees) to attend college has been widely discussed (Time.com). The following random samples show the annual cost of attending private and public colleges. Data are in thousands of dollars.
Private Colleges
53.8 42.2 44.0 34.3 44.0
31.6 45.8 38.8 50.5 42.0
Public Colleges
20.3 22.0 28.2 15.6 24.1 28.5
22.8 25.8 18.5 25.6 14.4 21.8
(a) Compute the sample mean (in thousand dollars) and sample standard deviation (in thousand dollars) for private colleges. (Round the standard deviation to two decimal places.)
(b) Compute the sample mean (in thousand dollars) and sample standard deviation (in thousand dollars) for public colleges. (Round the standard deviation to two decimal places.)
(c) What is the point estimate (in thousand dollars) of the difference between the two population means? (Use Private − Public.)
We estimate that the mean annual cost to attend private colleges is $ more than the mean annual cost to attend public college
(d) Develop a 95% confidence interval (in thousand dollars) of the difference between the mean annual cost of attending private and public colleges. (Use Private − Public. Round your answers to one decimal place.)
A marathon is 26.2 miles long. Jarrod is running a marathon and has completed 17.75 miles. How
many more miles to the finish line?
Answer:
Jarron has 8.45 more miles to get to the finish line.
Step-by-step explanation:
All we have to do is subtract the total number of miles by the number of miles Jarron has completed.
So: 26.20 - 17.75 = 8.45
26.2 - 17.75 = 8.45
All you need is subtraction because you are finding what is left.
You can find 8.45 by using a calculator or solving in your head, it would just take longer.

A population of cattle is increasing at a rate of per year, where is measured in years. By how much does the population increase between the 3rd and the 5th years
Using the rate function given and the subtraction operation, the increase in the population is 8
The rate of increase per year :
500 + 4tIncrement in the third year :
t = 3 :500 + 4(3)
500 + 12 = 512
Increment in 5th year :
t = 5500 + 4(5)
500 + 20 = 520
Change in size between 5th and 3rd year :
520 - 512 = 8Hence, population increased by 8 cattle.

Answer:
sin(C) = 24/26 (c)cos(C) = 10/26 (a)tan(C) = 24/10 (d)Step-by-step explanation:
The mnemonic SOH CAH TOA can help you remember the definitions of the trig relations:
Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent
__
In the given triangle, the side adjacent to angle C is marked 10; the side opposite is marked 24; and the hypotenuse is marked 26.
1. sin(C) = 24/26
2. cos(C) = 10/26
3. tan(C) = 24/10
