what is the equation of the line in slop-intercept form HELPP PLZZZZZZZZZZ
Answer:
y = 3/5x + 3
Step-by-step explanation:
(y2-y1)/(x2-x1) = slope
pick 2 points (0,3) and (-5,0)
(0-3)/(-5-0) = -3/-5 = 3/5
y = 3/5x + b
3 = 3/5(0) + b, b = 3
equation y = 3/5x + 3

PLs, help me - an international company has 18,700 employees in one country. If this represents 32.8% of the company's employees, how many employees does it have in total? Round your answer to the nearest whole number.
Answer:
33.6% of X = 26800
X = 26800 / 33.6%
= 26800 / 0.336
= 79762
Note the answer is rounded
Step-by-step explanation:
33.6% of X = 26800
X = 26800 / 33.6%
= 26800 / 0.336
= 79762
Note the answer is rounded

write the slope intercept form of the line that passes through the two points given (-1,-8) (2,10)
Answer:
y = 6x - 2
Step-by-step explanation:
Let the equation of the line be y = mx + c
m = (10 - (-8))/(2 - (-1)) = 6
sub (2, 10):
10 = 6(2) + c
c = -2
therefore, the equation of the line is y = 6x - 2

The length of a rectangle is twice the width if the perimeter of the rectangle 60 units find the area of the rectangle
Answer:
200
Step-by-step explanation:
Length = 2w
2w + 2l = 60
substitute l out with 2w
2w + 2(2w) = 60
2w + 4w = 60
w = 10
l = 20
Area = w • l
= 10 • 20
= 200

Archaeologists are studying a shipwreck on the
ocean floor. The wreck site is roughly shaped like a
parallelogram. The archaeologists make a map of the
site in the coordinate plane. Each unit on the map
represents 1 m. According to the map, what is the
area of the wreck site?
The area of the wreck site is 85 square m if Archaeologists are studying a shipwreck on the ocean floor.
What is parallelogram?
In two-dimensional geometry, it is a plane shape having four sides, in which two pairs of sides are parallel to each other and equal in length. The sum of all angles in a parallelogram is 360°.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have:
Archaeologists are studying a shipwreck on the ocean floor. The wreck site is roughly shaped like a parallelogram.
From the table:
The vertex of the P is (9, 2)
The vertex of the Q is (-8, 2)
The vertex of the R is (-7, 7)
The vertex of the S is unknown
From the distance formula we can find the distance between points P and Q:
The distance formula can be defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.
The distance formula can be given as:
[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]\rm PQ = \sqrt{(-8-(-9))^2+(2-2)^2}[/tex]
PQ = 17 units
[tex]\rm QR = \sqrt{(-7-(-8))^2+(7-2)^2}[/tex]
QR = 5.09 ≈ 5 units
The area of the wreck site = 17x5
The area of the wreck site = 85 square m
Thus, the area of the wreck site is 85 square m if Archaeologists are studying a shipwreck on the ocean floor.

Which is the better buy?
141-fuid-ource container of window clearer for
$7.05
6-pint container of window dieener for $3.84
Answer:
6-pint container of window clearer for $3.84 is a better buy
Step-by-step explanation:
141-fuid-ounce container of window clearer for $7.05
7.05 : 141 = 0.05
check your work: 0.05 x 141 = 7.05
so for the first offer you will be paying $0.05 per ounce of window clearer.
6-pint container of window clearer for $3.84
1 pint = 16 ounces
6 pints = 96 ounces
3.84 : 96 = 0.04
check your work: 0.04 x 96 = 3.84
for the second offer you will be paying $0.04 per ounce of window clearer. 6-pint container of window clearer for $3.84 is a better buy because you will be paying less for each ounce of window clearer.
Answer:
the 6-pint container would be cheaper...hope this helps :)
Step-by-step explanation:
X^3-4x^2+3x+2=0 find all the real values of x
Step-by-step explanation:
The factor of the polynomial is (x-2)
We know that dividing a third degree polynomial by a first degree factor will yield a quadratic of the form ax²+bx+c and possibly a remainder r,except that in this case r=0 since x-2 is a factor
We therefore equate
x³-4x²+3x+2=(x-2)(ax²+bx+c)+r
x³-4x²+3x+2=ax³+bx²+cx-2ax²-2bx-2c+r
We group terms on the RHS
x³-4x²+3x+2=ax³+x²(b-2a)+x(c-2b)-2c+r
By equating the terms on both sides,
ax³=x³,a=1
Next,
b-2a=-4
b-2(1)=-4
b-2=-4
b=-4+2
b=-2
Next,
c-2b=3
c-2(-2)=3
c+4=3
c=-1
Now we piece together our quotient quadratic using a=1,b=-2,c=-1 to obtain x²-2x-1
We now find the zeros of x²-2x-1
which are 1+√2 and 1-√2
The values of x are therefore 2,1+√2, and 1-√2
Note that I used this method in lieu of the famous polynomial division approach to teach someone also ;)
Answer:
2, 1 +/- sqrt2
or 2, 2.414, -0.414 (correct to the nearest thousandth).
Step-by-step explanation:
Let x = 2: then
f(2) = 8 - 16 + 6 + 2 = 0
So x = 2 is one of the zeros.
So one factor of the function is x-2.
If we divide the function by (x - 2) we get:
x-2)X^3-4x^2+3x+2(x^2-2x-1
x^3- 2x^2
-2x^2+3x
-2x^2+4x
-x+2
-x+2
.......
So x^2-2x-1= 0
x = [-(-2 +/- sqrt(4 - 4*-1)] / 2
x = (2 +/- sqrt8) / 2
= 1 +/-sqrt8/2
= 1 +/- sqrt2

Answer:
2nd option; [tex]c=9-a+b[/tex]
Step-by-step explanation:
The first thing you need to do, is rewrite the equation without the square root.So for instance [tex]\sqrt{16}=4[/tex] and [tex]16=(4)^2[/tex] therefore [tex]a-b+c=(3)^2[/tex] Then [tex]a-b+c=9[/tex] Now we take away ' [tex]a[/tex] ' on both sides and add ' [tex]b[/tex] ' on both sidesSo [tex]a-(a)-b+(b)+c=9-(a)+(b)[/tex] Which gives us [tex]0+0+c=9-a+b[/tex] which is simply [tex]c=9-a+b[/tex]Hope this helps

∠1 and ∠2 are a linear pair. If the m∠2 = 33°, find the m∠1.
Answer:
157 degrees
Step-by-step explanation:
A linear pair is 180 degrees.
180-33 = 157
Answer:
m∠1 = 147°
Step-by-step explanation:
Since both angles are a linear pair, they both add up to 180°. This means that if m∠2 = 33°, then m∠1 would be 180°-33° which is 147°.
180°-33°=147°
What is sieve of eratosthenes? (Only give paragraph, no steps)
Step-by-step explanation:
In Mathematics, the sieve of Eratosthenes is an ancient algorithm for finding all prime numbers up to any given limit. It does so by iteratively marking as composite (i.e., not prime) the multiples of each prime, starting with the first prime number, 2. The multiples of a given prime are generated as a sequence of numbers starting from that prime, with constant difference between them that is equal to that prime.This is the sieve's key distinction from using trial division to sequentially test each candidate number for divisibility by each prime.
