l=2·15+2·247.2
15=62.96m
Which equation represents the line through (4, -6) and (0, 2)?
Ill give brainlest to first RIGHT ANSWER.
Answer:
[tex]y=-2x+2[/tex]
Step-by-step explanation:
Hi there!
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x=0).
1) Determine the slope (m)
[tex]m=\displaystyle\frac{y_2-y_1}{x_2-x_1}[/tex] where two points that fall on the line are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the given points (4, -6) and (0, 2):
[tex]m=\displaystyle\frac{-6-2}{4-0}\\\\m=\displaystyle\frac{-8}{4}\\\\m=-2[/tex]
Therefore, the slope of the line is -2. Plug this into [tex]y=mx+b[/tex]:
[tex]y=-2x+b[/tex]
2) Determine the y-intercept (b)
The y-intercept occurs when x=0. We are given that (0,2) falls on the line, so therefore, 2 is the y-intercept. Plug this into [tex]y=-2x+b[/tex]:
[tex]y=-2x+2[/tex]
I hope this helps!
Answer:
y = - 2x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (4, - 6) and (x₂, y₂ ) = (0, 2 )
m = = = = - 2
The line crosses the x- axis at (0, 2 ) ⇒ c = 2
y = - 2x + 2 ← equation of line

Joe is a scientist who works with the Department of Agriculture. In order to ensure a good harvest, Joe keeps track of various local beetle populations. He catches 590 beetles, marks them, and releases them. Then later, he catches 2,000 beetles, 59 of which are marked. To the nearest whole number, what is the best estimate for the beetle population?
( 11 points if solved)
Will give brainliest, if the answer is correct OR well explaining explanation ( Either Both)
Answer:
There are 20,000 Beatles in the total population
Step-by-step explanation:
59 Beatles out of the 2,000 are marked (2.95% or 59/2000)
-----------------------------------------
1 / 0.0295 = 33.8983051
That means that the total population is 33.89 times larger than the 590 marked beatles.
33.8983051 x 590 = 20,0000 Beatles total
Answer:
Approximately 20,000 beetles
Step-by-step explanation:
The answer is approximately 20,000 beetles because Joe found 590 beetles and marked them. When he found the other 2,000 beetles, 59 of them were marked. 59 is 10% of 590. Since Joe found 2,000 beetles that must be 10% of some number. To find that number, you must multiply 2,000 by 10. So 2,000 x 10 is 20,000, so there is approximately 20,000 beetles
4 3/5 + 5 1/2
Help me please and thank you
Answer:
Step-by-step explanation:
4 3/5 + 5 1/2= (10 1/10)
Step 1: Find the common multiple between the numbers, and simplify-
4 3/5=4 6/10 5 1/2= 5 5/10
Step 2: Convert to improper fractions-
4 6/10 as an improper fraction is 46/10 and 5 5/10 as an improper fraction is 55/10 (Formula for mixed numbers to improper fractions is denominator multiplied by whole number plus numerator)
Step 3: Add numerator of improper fractions, then add back denominator-
46+55=10 1 numerator:101 denominator:10 101/10
Step 4: Convert into mixed number-
101/10= 10 1/10
ANSWER: 10 1/10
Answer:
10.1
Step-by-step explanation:
Conversion a mixed number 4 3/
5
to a improper fraction: 4 3/5 = 4 3/
5
= 4 · 5 + 3/
5
= 20 + 3/
5
= 23/
5
To find a new numerator:
a) Multiply the whole number 4 by the denominator 5. Whole number 4 equally 4 * 5/
5
= 20/
5
b) Add the answer from previous step 20 to the numerator 3. New numerator is 20 + 3 = 23
c) Write a previous answer (new numerator 23) over the denominator 5.
Four and three fifths is twenty-three fifths
Conversion a mixed number 5 1/
2
to a improper fraction: 5 1/2 = 5 1/
2
= 5 · 2 + 1/
2
= 10 + 1/
2
= 11/
2
To find a new numerator:
a) Multiply the whole number 5 by the denominator 2. Whole number 5 equally 5 * 2/
2
= 10/
2
b) Add the answer from previous step 10 to the numerator 1. New numerator is 10 + 1 = 11
c) Write a previous answer (new numerator 11) over the denominator 2.
Five and one half is eleven halfs
Add: 23/
5
+ 11/
2
= 23 · 2/
5 · 2
+ 11 · 5/
2 · 5
= 46/
10
+ 55/
10
= 46 + 55/

If I’m in daep and got 30 days started oct 22 how long will it be till I get out minus all the weekends?
Answer:
30
Step-by-step explanation:
Alonzo will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $50 and costs an additional 0.10 per mile driven. The second plan has no initial fee but costs 0.60 per mile driven. How many miles would Alonzo need to drive for the two plans to cost the same?
Answer:
for plan B if he rides for 100 miles he will pay 60$
for plan A if he rides for 100 miles he will pay 60$
Step-by-step explanation:
the reason is that B. 100x0.60=60
and A (100x0.10)+50=60
Answer:
100 miles
Step-by-step explanation:
If Alonzo drives 0 miles, then the first plan would cost him 50 dollars and the second plan would cost him nothing.
If Alonzo drives 10 miles, then the first plan would cost him 51 dollars and the second plan would cost him 6 dollars.
From these statements, we can observe that the second plan is increasing at a rate 6 times the first one and will overtake it at one point.
Our solution is the point of intersection between these two functions - where they cost the same.
To find this, equate
0.1x + 50 = 0.6x
where x is the number of miles Alonzo drives,
multiply the equation with 10 to get,
x + 500 = 6x
subtract x,
5x = 500
and divide 5,
x = 100.
So at 100 miles, both plan 1 and 2 will cost 60$. This is our answer. Good Luck!

You are creating your own real-world problem or word problem using Pythagorean Theorem. You create the problem and solve it. Use what you find to help you create your own problem. It does not have to be a really hard problem.
Answer:
A man's garden keeps getting attacked by rabbits, so he decides to put a fence around it. the garden is in the shape of a right triangle. The people who build the fence measure side a and b, side a has a length of 6 yards. Side b has a length of 8 yards. What is the total length (in yards) of fence the builders will need?
The pythag equation is:
a^2+b^2 =c^2
So, we plug in 6 for a and 8 for b and we get:
(6*6)+(8*8)=c*c
36+64=c*c
100=c*c
Now, we all know that 10*10 is 100 so:
c=10
Now we add 10 to 8 and 6 and we get:
24
The builders will need 24 yards of fence.

-5= -10+y how do i reorder this and why do i reorder it in that way? i think i know how to reorder it i'm just confused on why it has to be ordered that way. plz help, thanks!
Answer:
y = 5
Step-by-step explanation:
Ok so you need to move y to its own spot so either on the right or left of the equation. BUT i recommend leaving it and instead moving -10 to the other side. REMEMBER when you move a number to the other side of the equation you change its value so instead of -10 it will become +10. so you will get 10-5=y so 5=y, if you want the y to be on the other side flip them around -y=-5(since you switched them you need to make them minus, or plus if the number was originally negative) SINCE you have minuses on both sides you can cancel them out and you will be left with y=5.
Why you need to reorder:
you need to reorder to find Y there is no way you can find Y without reordering. When you are reordering remember that Y has to be by itself in one side of the equation.

What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
On Friday, the number of friends Sharon called 4 friends
On Saturday, the number of each of those 4 friends called 4 different friends.
Therefore, the number of friends on Saturday = 4 × 4
= 16
The number of friends called on, Sunday = 16 × 4
= 64
Hence, the number of friends called on Sunday is; 64.
