Write an equation for a line that passes through (3, -4) & has a slope of -3.
Answers
Answer:
The answer is
[tex] \huge y = - 3x + 5[/tex]
Step-by-step explanation:
To find an equation of a line when given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
From the question we have
[tex]y + 4 = - 3(x - 3) \\ y + 4 = - 3x + 9 \\ y = - 3x + 9 - 4[/tex]
We have the final answer as
[tex]y = - 3x + 5[/tex]

Find the value of x.
Answers
Answer:
x = 19
Step-by-step explanation:
The sum of both angles will be equal to a supplementary angle. A supplementary angle is when two angles add up to be 180°. Write an equation and solve for x.
3x + 5 + 7x - 15 = 180
~Combine like terms
10x - 10 = 180
~Add 10 to both sides
10x = 190
~Divide 10 to both sides
x = 19

r + 8 - 5r = 2(4 - 2r) solve for r please
Answers
-4r + 8 = 8 - 4r
0 = 0 so it's like {}
Answer:
r = 0
Step-by-step explanation:
This is actually the first time I've actually had a equation with the variable equaling 0.
so first things first you have the equation:
r + 8 - 5r = 2(4 - 2r)
so you are going to add or multiply all the variable numbers together and the none variable numbers together like so:
r + (-5r) and (2*4) and (2* (-2r)) to get the equation looking like so:
8+ (-4r)= 8 -4r
you then add -4r to both sides to get this equation:
8+ ( -4r)= 8 -4r
+ 4r +4r
8 = 8 + r
you then subtract 8 from both sides to get r:
8 = 8 + r
-8 -8
0 = r
to check substitute the 0 into r in the equation:
r + 8 - 5r = 2(4 - 2r)
0 + 8 - (5*0) = 2(4- (2*0))
8 = 8
Tada!!!

Cami goes scuba diving. She descends 18 feet in 3 minutes. Which expressions represent the average rate at which Cami’s position changes in feet per minute?
Answers
Answer:
6 ft/min
Step-by-step explanation:
Theres a neat trick to note; whenever you say per think of it as a fancy word for divide, because the label is always gonna be a/b (a per b)
Therefore,
the rate of feet per minute will be the feet divided by the minutes;
18 feet in 3 minutes = 18/3 ft/min
Therefore the rate is 6 feet per minute.
IF you need an explanation on what average rate implies:
Note; the word average is not prudent to answer as its extraneous, however if there was more data like "Cami descends 18 ft in 3 min and Nami descends 9 ft in 3 minutes; whats the average rate at which they descend" then you'd have to add the two rates up and divide by two.

Step-by-step explanation:
a(b ± c) = ab ± ac (distributive property)
[tex]a^{m} * a^{n} = a^{m+n}[/tex]
2r²(6r³ + 14r² - 30r + 14) = 12 [tex]r^{5}[/tex] + 28 [tex]r^{4}[/tex] - 60 r³ + 28 r²

y=3/2x+5/2
Step-by-step explanation:
I used the Y2-Y1/X2-X1
In this equation you can see that there are 2 points (-5,-5) and (1,4)
If you substitute, you will get
4+5/1+5
9/6 and if you simplify this, you will get 3/2
Now that we have the slope, we just have to use y=mx+b
(I'm using the point (1,4)) 4=3/2(1)+b
4=3/2+b
5/2=b
