What is the equation of the line that passes through the point (-4, 2) and
has a slope of -2?
Answer:
y-2 = -2(x+4)
or
y = -2x-6
Step-by-step explanation:
We can use the point slope form of a line
y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y - 2 = -2(x- -4)
y-2 = -2(x+4)
If we want the equation in slope intercept form
Distribute
y-2 = -2x-8
Add 2 to each side
y-2+2 = -2x-8+2
y = -2x-6

What is permutation?Permutation is a mathematical calculation of the number of ways a particular set can be arranged, where order of the arrangement matters.
Permutation Formula[tex]^{n} P_{r} = \frac{P!}{(n-r)!}[/tex]
Where,
[tex]^{n}P_{r}[/tex] is permutation
n is the number of objects
r is the number of objects selected.
According to the given question.
Total number of blouses = 9
Total number of skirts = 8
So,
the number of ways of choosing one blouse from 8
=[tex]^{8} P_{1}[/tex]
= [tex]\frac{8!}{(8-1)!} \\[/tex]
= [tex]\frac{8!}{7!}[/tex]
= [tex]\frac{8\times 7!}{7!}[/tex]
= [tex]8[/tex]
And the number of ways of choosing one skirt from 9
[tex]^{9} P_{1} \\= \frac{9!}{(9-1)!} \\= \frac{9\times 8!}{8!} \\=9[/tex]
Therefore,
The total number of ways of choosing two piece outfit from 9 blouses and 8 skirts
= [tex]^{8} P_{1} \times ^{9} P_{1}[/tex]
= [tex]8 \times 9[/tex]
[tex]= 72[/tex]
Hence, the total number of ways a girl can choose a two-piece outfit from 9 blouses and 8 skirts is 72.

Evaluate f(x)=2x+8 when x=−2, x=0, and x=5.
f ^− 1 ( x ) = x/2 − 4
That is the inverse
The value of the function, for x=-2 is 4.
The given function is f(x)=2x+8.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
When x=-2, we get
f(-2)=2(-2)+8
=4
When x=0, we get
f(0)=2(0)+8
= 8
When x=5, we get
f(5)=2(5)+8
= 18

Solve the equation a = m - n for the variable n.
Answer:
n = m - a
Step-by-step explanation:
a = m - n
add n to both sides of the equation
a + n = m - n + n
a + n = m
subtract a from both sides of the equation
a - a + n = m - a
n = m - a
Answer:
n = a - m
Step-by-step explanation:
a = m - n
a - m = n

A ball is thrown vertically upward from the top of a 100-foot tower, with an initial velocity of 20 ft/sec. Its position function is s(t) = -16t^2 + 20t + 100. What is its velocity in ft/sec when t = 1 second?
The velocity of the ball in ft/sec, when t = 1 second is equal to -12 ft/sec.
Given the following data:
Displacement = 100 feetTime = 1 secondsPosition function = [tex]s(t) = -16t^2 + 20t + 100[/tex]To calculate the velocity of the ball in ft/sec, when t = 1 second:
Mathematically, the velocity of an object or physical body is equal to the differentiation of it's position function.
Velocity = s'(t)
Velocity = [tex]s(t) = -16t^2 + 20t + 100[/tex]
[tex]Velocity = -32t + 20[/tex]
Substituting the value of time (t), we have:
[tex]Velocity = -32(1) +20\\\\Velocity =-32+20[/tex]
Velocity = -12 ft/sec

You have at most $20 to spend at an arcade. Arcade games cost $0.75 each, and snacks cost $2.25 each. Write an inequality that represents the numbers of games (x )you can play and snacks( y) you can buy.
The inequality is ??
Answer:
y ≤ -1/3x+80/9
Step-by-step explanation:
(1). 0.75(x)+2.25(y) ≤ 20
0.75 - Number of arcade games (X).
2.25 - Number of snacks (Y).
20 - The total.
(2). 0.75x+2.25y≤20
(After multiplying the x's and y's together, with the numbers).
(3). 0.75x (-0.75x) + 2.25y ≤ 20 (-0.75x)
(Subtract -0.75x to each side, which allows the equation to get closer to the answer).
(4). 2.25y -0.75x + 20
———— = ————
2.25 2.25
(Divide by 2.25 to each side).
(5). y ≤ -1/3x + 80/9

3 more gray were sold than white
3 colors sold 10 or more
Answer:
a) White
b) 3
c) 3
Step-by-step explanation:
a) White as it is the shortest bar (has the lowest height and only has 4 t-shirts sold)
b) According to the bar graph, 7 grey t-shirts were sold and 4 white t-shirts were sold. Subtracting 4 from 7 = 7-4 = 3
Hence, 3
c) At least 10 T-shirts sold, suggests that it was greater than or equal to 10. According to the graph, black has 12, tan has 11, and brown has 10. Hence,
3 colors had at least 10 t-shirts sold.
