point-slope equation of the line: y+1 = -(x-3)
rearrange to solve for y:
y+1 = -x+3
y = -x + 2 slope-intercept form
Answer:
y = -x + 2
Step-by-step explanation:
We are given that a line has a slope of -1 and passes through the point (3, -1)
We want to write the equation of this line in slope-intercept form
Slope-intercept form is written as y=mx+b, where m is the slope and b is the value of y at the y intercept
As we are already given the slope, we can immediately plug its value into y=mx+b.
Replace m with -1 in y=mx+b.
y = -x + b (there's no need to write -1 in front of x. If -1 is the coefficient in front of a variable, just writing a minus sign in front of the variable is enough).
Now we need to find b.
As the equation passes through the point (3, -1), we can use it to help solve for b.
Substitute 3 as x and -1 as y.
-1 = -3 + b
Add 3 to both sides
2 = b
Substitute 2 as b in the equation so far.
y = -x + 2

Find the area of the shaded section.
3 cm
9 cm
7 cm
16cm
Answer:
The area of the shaded portion is 123 cm^2
Step-by-step explanation:
Here, we want to find the area of the shaded portion
To find this, we subtract the area of the smaller inner rectangle from that of the outside bigger one
Mathematically, the area of a rectangle at any point in time is length * width
For the bigger one, we have;16 * 9 = 144 cm^2
For the smaller inner one, we have ;3 * 7 = 21 cm^2
The area of the shaded portion which is the difference is;
144-21 = 123 cm^2

5. A softball has a diameter of 8.3 in. How many softballs will fit inside of a storage unit 4 that is 15 feet wide, 10 feet long, and 5 feet high?
Answer:
4329 softballs
Step-by-step explanation:
To find the number of softballs that will fit into the container, we first find the volume of the softball. Since it is a sphere, its volume V = 4πr³/3 where r = radius = d/2 where d = diameter of softball.
So, V = 4π(d/2)³/3 = πd³/6
Since d = 8.3 in,
V = πd³/6 = π(8.3 in)³/6 = π × 571.787 in³/6 = 299.39 in³
The volume of the box, V' = 15 × 10 × 5 ft³ = 750 ft³ = 750 × (12 in)³ = 750 × 1,728 in³ = 1,296,000
So, for n softball to fit, its volume must equal the volume of the storage unit.
The volume of n softballs is nV.
For the softballs to fit, V' = nV
n = V'/V
= 1,296,000 in³/299.39 in³
= 4328.8 softballs
≅ 4329 softballs since we cannot have a decimal number of softballs.

Which algebraic expression represents “the quotient of 7 and a number”?
Answer: D
Step-by-step explanation: its best you can get to the a quotient (from Latin: quotiens "how many times", pronounced) is a quantity produced by the division of two numbers. The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division (in the case of Euclidean division), or as a fraction or a ratio (in the case of proper division). For example, when dividing 20 (the dividend) by 3 (the divisor), the quotient is 6 in the Euclidean division sense, and 62/3 in the proper division sense.

after 7 years, an initial investment of $600 earned $84. Find the interest rate
Answer:
2%
Step-by-step explanation:
Solving our equation
r = 84 / ( 600 × 7 ) = 0.02
r = 0.02
converting r decimal to a percentage
R = 0.02 * 100 = 2%/year
The interest rate required to
accumulate simple interest of $ 84.00
from a principal of $ 600.00
over 7 years is 2% per year.
The ratio of potatoes to carrots in a vegetable cart is 1:1. If there are 473 carrots, how many potatoes are there?
Answer:
473 potatoes
Step-by-step explanation:
473/1 = 473
(Plus anything times/divided by 1 equals itself)
so 1:1 x 473:473 = 473:473
Therefore there are 473 potatoes
Answer:
473 potatoes
Step-by-step explanation:
The ratio is 1:1, meaning that for every carrot, there is a potato.

Horizontal Asymptote: y = 0
Question 3 x-intercept: (3,0) & (-3,0) Vertical Asymptote: X=-1 & x= -4
Horizontal Asymptote: y = 1
Question 4. X-intercept: (-2, 0)
Vertical Asymptote: X = 4 & x=-5 Horizontal Asymptote: y=0

Q3: [tex]\frac{(x-3)(x+3)}{(x+1)(x+4)}[/tex]
Q4: [tex]\frac{x(x+2)}{(x-4)^{2}(x+5) }[/tex]
Step-by-step explanation:
If there is a vertical asymptote at x=k, then the denominator must contain a term (x-k) or (x-k) raised to a positive integer power.
If there is an x intercept at k, then the numerator must contain a term (x-k) or (x-k) raised to a positive integer power.
If there is a horizontal asymptote of 0, then the highest power of x in the denominator must exceed the highest power of x in the numerator.
If thee is a horizontal asymptote of k, then the highest power of x in the numerator and denominator must be the same and the ratio of their coefficients (numerator to denominator) must be k.

How many distinct permutations can be made from the letters of the word
“INDEPENDENCE”?
if anyone could answer, thank you (^-^)
Answer:
360
Step-by-step explanation:
Word INDEPENDENCE has I−1, N−3, D−2, E−4, P−1, C−1
There are six different letters in INDEPENDENCE
Now according to the question, we need to form 4 different letter words, So the selection of 4 words out of 6 is
[tex]^{6}C _{4}[/tex]
and making its arrangements
So total number of ways is
[tex]^{6}C _{4}[/tex] ×4!=360
The number of distinct permutations can be made from the letters of the word “INDEPENDENCE” is; 1663200
We are given the word INDEPENDENCE and it has;
I − oneN - threeD − twoE - fourP - oneC - oneThus, we see that there are six different letters and 12 letters in total in INDEPENDENCE
Now from the question, the distinct permutations that can be formed is;
12!/(3! × 2! × 4!) = 1663200

Desmond plays 30 minutes of soccer each day. How many seconds of soccer does Desmond play in 6 days?
Answer:Desmond will play for 10800 seconds in 6 days
Step-by-step explanation:
In a Day Desmond plays soccer = 30 minutes
In 6 days, he will play = 6 x 30 = 180 minutes
Changing 180 minutes to seconds
we know that 60 second s= 1 minutes
Therefore ?? seconds = 180 minutes
180 x 60 =10800 seconds

D.
(3.5,297.5)
E.
(4,350)
Answer:

(A) 1*85-85
(B) 0.85*85 = 72.75
(C) 0.2*85 = 14
(D) 3.5*85 = 297.5

6. You have $1.95 in quarters and dimes. You have 12 total coins. How many of each denomination
do you have? IS
Step-by-step explanation:
d+q =12
.25q + .10d = 1.95
d = 12-q
substitute
.25q + .10(12 -q) =1.95
.25q + 1.2 - .1q = 1.95
.15q = .75
q = 5. quarters
d + 5 = 12
d = 7 dimes
Answer:
5 quarters and 7 dimes
Step-by-step explanation:
5 quarters = $1.25
7 dimes = $0.70
7 + 5 = 12

Answer:
x = 2
y = 6
Step-by-step explanation:
We have a system of equations and are asked to solve for x and y.
y = -2x + 10
y = 3x
Since both equations start with y, we can subtitute.
3x = -2x + 10
Solve for x :
Add 2x to both sides :
5x = 10
Divide 5 from both sides :
x = 2
Now substitute x in the second equation because it's more easier :
y = 3(2)
3(2)
6
y = 6
