Answer:
y + 1 = -1/4 (x - 1) Answer choice C is correct.
Step-by-step explanation:
Point Slope Formula: y - y1 = m (x-x1)
Your points:
(1,-1) and (5,-2)
You need to find the slope first:
Use the formula: y2 - y1 / x2 - x1
Your y2 is -2
y1 is -1
x2 is 5
x1 is 1
-2 - (-1)/5-1
-2 + 1 /4
-1/4 is your slope and the "m" in the formula.
Now we know our y1 is -1 and x1 is 1 you just need to plug them in
y + 1 = -1/4 (x - 1)
Notice that I didn't write y - (-1) this is because the negatives cancel into positives.
Answer choice C is correct.
Answer:
c. [tex]y+1=-\frac{1}{4} (x-1)[/tex]
Step-by-step explanation:
Hi there!
We are given the points (1, -1) and (5, -2)
We want to find the equation of that line using those points, in point-slope form
Point-slope form is written as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is a point
First, let's find the slope of the line
The formula for the slope (m) calculated from 2 points is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points
We already have everything we need to find the slope, but let's label the values of the points to avoid any confusion when calculating.
[tex]x_1=1\\y_1=-1\\x_2=5\\y_2=-2[/tex]
Now substitute:
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m=[tex]\frac{-2--1}{5-1}[/tex]
Subtract
m=[tex]\frac{-2+1}{5-1}[/tex]
m=[tex]\frac{-1}{4}[/tex]
The slope of the line is -1/4
Now substitute this into the formula to find point-slope form (remember that this is [tex]y-y_1=m(x-x_1)[/tex], and that m is the slope value)
Therefore:
[tex]y-y_1=-\frac{1}{4} (x-x_1)[/tex]
Now, let's substitute the values of [tex]x_1[/tex] and [tex]y_1[/tex], which we found earlier (which are 1 and -1 respectively) into the equation
[tex]y--1=-\frac{1}{4} (x-1)[/tex]
Simplify
[tex]y+1=-\frac{1}{4} (x-1)[/tex]
This equation matches option c, which is the answer.
Hope this helps!

Step-by-step explanation:
Find the volume. Please help! Thanks!
hehe
Volume of a Square Pyramid: 1/3 x length x width x height
Length = 2
Width = 2
Height = 3
Volume = 1/3 x 2 x 2 x 3
Volume = 1/3 x 4 x 3
Volume = 1/3 x 12
Volume = 4
Volume = 4 cm^3

What would you do if fear was not a factor and you could not fail?`
i know it's not a maths question but let's try
Answer:
Well, i would just say you just had to do your best in everything that you do. No pressure , no stress don't overwork yourself and simply take action. Then you will have a chance to get what you want because you tried your best to get to it. Although sometimes we don't get what we want, atleast we'll be closer.

Students from four classes are in talent show. A. There are 28 students in Ms. Fiona's class. The ratio of her student who are in the talent show to those who are not in the talent show is 2:5. How many of Ms. Fiona's students are in the talent show? B. Mr. Juan has 24 students in his class. Some of his students are also in the talent show. Explain why it is not possible for exactly 24% of the students in Mr. Juan's class to be in the talent show. C. The rest of the students in the talent show are from Mrs. Lee's class and Mr. Greg's class. • Mrs. Lee has 23 students in her class, and 7 of them are in the talent show. There are 4 more students from Mr. Greg's class than from Mr. Juan's class in the talent show. The number of students in the talent show from Mrs. Lee's class is greater than the number from Mr. Juan's class and fewer than the number from Mr. Greg's class. In all, 30% of the students in these three classes are in the talent show, Show or explain why there must be exactly 23 students in Mr. Greg's class. As part of the explanation, determine how many students from Mr. Greg's class are in the talent show

10+500000000 wats the answer
Answer:
500,000,010
Step-by-step explanation:
The 10 would be added to the last 2 digits (00) of the number. Therefore, the last 2 digits (00) plus 10 would be 10. The remainder of the number would remain the same, making the answer: 500,000,010

250 gram as a percentage of 1 kg
Hey there!
Answer: 25%
[tex] \rightarrow \: (\sf{ \frac{250}{1000} ) \times 100}[/tex]
[tex] \rightarrow \: ( \sf{0.25) \times 100}[/tex]
[tex] \rightarrow \: \sf{ = 25\%}[/tex]
Answer:
25%
Step-by-step explanation:
the quantities must have the same units
1 Kg = 1000 grams
express the quantities as a fraction and multiply by 100%
[tex]\frac{250}{1000}[/tex] × 100% = 0.25 × 100% = 25%

how many cubic inches of hot air would be needed to completely inflate a 12 in diameter beach ball
Answer:
904.78 cubic inches
Step-by-step explanation:
Since a beach ball is a sphere, use the formula for volume, V = 4/3 * pi * r^3 to find the volume of the beach ball, using 6 for radius since diameter is two times the radius and the diameter is 12 inches. 4/3 * pi * 6^3 = 904.78, so that many cubic inches of air would be needed to inflate the beach ball.
Hopefully this helps- let me know if you have any questions!

A radioactive substance decays exponentially. A scientist begins with 190 milligrams of a radioactive substance. After 19 hours, 95 mg of the substance remains. How many milligrams will remain after 36 hours?
Answer:
51 milligrams
Step-by-step explanation:
Exponential growth or decay can be modeled by the equation ...
y = a·b^(x/c)
where 'a' is the initial value, 'b' is the "growth factor", and 'c' is the time period over which that growth factor applies. The time period units for 'c' and x need to be the same.
In this problem, we're told the initial value is a = 190 mg, and the value decays to 95 mg in 19 hours. This tells us the "growth factor" is ...
b = 95/190 = 1/2
c = 19 hours
Then, for x in hours the remaining amount can be modeled by ...
y = 190·(1/2)^(x/19)
__
After 36 hours, we have x=36, so the remaining amount is ...
y = 190·(1/2)^(36/19) ≈ 51.095 . . . . milligrams
About 51 mg will remain after 36 hours.
