Two of the points on this line are (-10, 8) and (5, -1). What is the slope of this line?
A
m = 15
B
m = 9/5
C
m = -3/5
D
m = 2
Answer:
C) m = -3/5Step-by-step explanation:
Formula for finding slope
m = y₂ - y₁ / x₂ - x₁Substituting the given points
m = -1 - 8 / 5 - (-10)m = -9/15m = -3/5I need helps plssssss. If you could explain that would be great!

Answer:
5√15
Step-by-step explanation:
(√3 + √48)(√20 - √5)
step 1 simplify √48
(√3 + 4√3)(√20 - √5)
step 2 add √3 and 4√3
(5√3)(√20 - √5)
step 3 simplify √20
(5√3)(2√5 - √5)
step 4 subtract √5 from 2√5
(5√3)(√5)
step 5 multiply 5√3 and √5
= 5√15
explanation of each step
step 1 and 3
To simplify radicals you list the factors of the number under the sqaure root
For 48 we have 2 × 2 × 2 × 2 × 3
We then pair the factors off as powers of 2 if possible
We get 2² × 2² × 3 which can further be simplified as 4² × 3
We then list the number with the power on the outside of the radical and leave the numbers with no power on the inside to get 4√3.
This process is used to simplify √20 as well.
step 2 and 4
For these two steps we are adding and subtracting radicals with the same radicand ( number inside of the square root. ) This is very simply as we keep the radicand the same and just perform the operation to the coeffecients ( number on the outside of the square root )
Eg. a√b + c√b = (a+c)√b or a√b - c√b = (a-c)√b
Hence, 4√3 + √3 = (4+1)√3 = 5√3
Step 5.
Finally we multiply the two radicals. This is very simply as we can use the rule to do so.
a√b × c√d = (a×c)√b×d
Hence, 5√3 × √5 = (5×1)√(3×5) = 5√15
Basketball tickets were $5 for the floor seats and $2 for the grandstand seats
If 210 people attended and paid $660, how many people bought floor seats?
Answer:
Good seats sold=80
Poor seats sold=130
Step-by-step explanation:
g + p = 210 seats. Then p = 210 - g.
($5)g + ($2)p = $660. Substite 210 - g for p,
($5)g + ($2)(210 - g) = $660
Simplify, 5g + 420 - 2g = 660 => 3g = 240 => g = 80
80 and 130

Step-by-step explanation:
A circular hot spring has a diameter of 96 meters. Over time, the diameter of the spring decreases by 8 meters. By how many square meters does the area of the hot spring decrease? Use 3.14 for pi.
about (BLANK) m2
The area decreases by 1155.52 square meters
Step-by-step explanation:What we must do is calculate the area before and after making the diameter cut.
The area of a circle is equal to:
a = pi * r ^ 2
now the diameter is equal to:
d = 2 * r
therefore r,
r = d / 2
before the cut would be
r = 96/2
r = 48
replacing in the area formula
a1 = 3.14 * 48 ^ 2
a1 = 7234.56 square meters.
after cutting the diameter decreases by 8, that is, 96 - 8 = 88, calculating the radius would be:
r = 88/2
r = 44
now calculating the new area would be:
a2 = 3.14 * 44 ^ 2
a2 = 6079.04 square meters.
now we calculate the difference
a1 - a2 = 7234.56 - 6079.04
= 1155.52 square meters
means that the area decreases by 1155.52 square meters

Answer:
Step-by-step explanation:
Given the slope-intercept form:[tex]y=\frac{1}{3}x-2[/tex]
Slope-intercept form: [tex]y=mx+b[/tex]
We substitute our x-values (-9, -3, 0, 6, and 9) for x in [tex]y=\frac{1}{3}x-2[/tex] to find the y-values.
For -9:
[tex]y=\frac{1}{3}x-2 < ==substitute\ -9\ for\ x\\\\y=\frac{1}{3}(-9)-2\\\\y=\frac{-9}{3}-2 < ==divide\ (don't\ forget\ the\ signs)\\\\y=-3-2 < ==add\ or\ subtract\\\\y=-5 < =value\ of\ y\\\\(-9,-5)[/tex]
For -3:

For 0:
[tex]y=\frac{1}{3}x-2 < ==substitute\ 0\ for\ x\\\\y=\frac{1}{3}(0)-2 < ==any\ number\ multiplied\ by\ 0\ equals\ zero\\\\y=\frac{0}{3}-2 < ==divide\ (don't\ forget\ the\ signs)-zero\ divided\ by\ any\ \#\ equals\ 0\\\\y=0-2 < ==add\ or\ subtract\\\\y=-2 < =value\ of\ y\\\\(0,-2)[/tex]
For 6:

For 9:

Step-by-step explanation:
Because you need to match the limit, you first have to convert in. to ft. That will get you at 2.3 (it is an non-stopping number, so I rounded to the tenths). 11 x 2.3 is 25.3. You can’t go lower, so you have to have that extra soccer ball. Hope this helps.

what is the area of this parallelogram 74.20 meters squared 154.50 meters squared 227.63 meters squared or 331.50 meters squared
Answer:
227.63 meters^2
Step-by-step explanation:
The formula to find an area of a parallelogram is a = bh (base multiplied by height). According to the figure, the base is 22.1 meters and the height is 10.3 meters.
a = bh
a = 22.1(10.3)
a = 227.63 meters^2
