Answer:
Step-by-step explanation:
y = mx + b
m is the slope (what you want)
b is the y-intercept, which is the value of y when x = 0
Oh, right, we already have b, isn't that great!
Given point (0, -4), so b = -4
Point (-2, -1), where x = -2 and y = -1
-1 = -2m -4 (solve for m)
3 = -2m
m = -3/2
Check:
y = -3x/2 -4
y = -3(-2)/2 -4 -> should get y = -1
y = 3 -4 = -1
Yay, we have the answer!

In the diagram, △ABC∼△CDE. Write an equation for line k
Answer:
Step-by-step explanation:
Line AB is parallel to line CD (k) so they have the same slope.
slope=m=(y2-y1)/(x2-x1)
m=(6-0)/(4-0)
m=6/4=1.5
y=mx+b, we know m=1.5 so
y=1.5x+b, and we know it passes through point (4,0) so we can solve for b
0=1.5(4)+b
0=6+b
b=-6 so line k is
y=1.5x-6
A bag has sixteen marbles in it. There are four of each color. There
are four red, four blue, four green and four yellow.
What is the probability that you will pull a red marble out of the bag?
Answer: 25 percent
Step-by-step explanation:
The probability of pulling out a red colored marble is [tex]\frac{1}{4}[/tex] or 25%.
What is probability?'Probability is a branch of math which deals with finding out the likelihood of the occurrence of an event.'
According to the given problem,
Total number of marbles = 16
Number of red marbles = 4
Probability = [tex]\frac{No of possible outcomes}{Total number of outcomes}[/tex]
The number of possible outcome is the number of red marbles = 4
Total number of outcomes is the total number of marbles = 16
⇒ Probability = [tex]\frac{4}{16}[/tex]
= [tex]\frac{1}{4}[/tex]
or, [tex]\frac{1}{4}[/tex] × 100
= 25%
Hence, the probability of pulling out a red marble is 25%.

Jim's parents keep a chart on the wall where they mark how much Jim grows each year. When Jim was 15, he grew 1/4 of an inch and when he was 16, he grew 1/2 of an inch. In total, how much did Jim grow in during those two years?
Answer: 3/4 inch
Step-by-step explanation:
When Jim was 15, he grew 1/4 of an inch and when he was 16, he grew 1/2 of an inch.
His growth during those two years will be:
= 1/4 + 1/2
= 1/4 + 2/4
= 3/4 inch
His growth increased by 3/4 inches.

A tank that is 40% full contains 650 gallons of water. On a side sheet of paper, use a double number line to find the maximum capacity of the water tank.
What did you get?
gallons
Answer: max capacity is 1625 gallons.
Diagram is shown below.
=========================================================
Explanation:
We'll draw two horizontal number lines to help make a comparison or connection between percentages and tank capacity.
For the top number line, make 5 sections with the labels: 0%, 20%, 40%, 60%, 100%. The reason I'm picking 5 is because 40% = 40/100 = 2/5. So having 40% capacity means we're 2/5 full. That denominator 5 tells us how to subdivide each number line.
The bottom number line will also have 5 sections. We only know one label for this bottom portion right now. That label is 650. Place this directly under the "40%". This visually is one way to represent that 650 gallons is 40% filled. See the diagram below.
Cut the 650 in half to get 325. This corresponds to 40% cut in half to get 20%. Therefore, 325 will go under the 20%. Being 20% full means we have 325 gallons of water.
To figure out the 60% portion, we will multiply 325 by 3. This is because 3*20% = 60%, so 3*325 = 975. We'll write "975 gallons" under the "60%"
Then we have 1300 gallons under the 80% since 4*325 = 1300. Note how 4*20% = 80%, so that's where the '4' multiplier comes from.
Finally, we multiply 325 by 5 to get 1625 and that represents the full tank's capacity. Technically we could have just jumped to this directly without having to find the 60% or 80% capacity values, but it's good practice I think.
Again the diagram is shown below. The answer we're after is at the very bottom right corner. It's under the 100% to indicate the tank is completely full, or has reached max capacity.
-----------------------
Here's a way to find the answer without a double number line. This method involves setting up a proportion.
(40% full)/(650 gallons) = (100% full)/(x gallons)
40/650 = 100/x
40x = 650*100
40x = 65000
x = 65000/40
x = 1625
We confirm that the tank's max capacity is 1625 gallons.

Two other rabbits arrive on deserted Pepper Island; these rabbits triple every 4 weeks. At the end of the 12 weeks, one python arrives on each island. As each python grows, the number of rabbits it can eat each week doubles. The first week, each eats 1 rabbit, the second week, 2, and so forth. How long will it take the python to wipe out the rabbits on each island?

It will take it 7 weeks

Answer:
x = 11
Step-by-step explanation:
33 divided by 3 is 11, and 11 times 3 is 33.
answer:
11
step-by-step explanation:
the easiest way to explain this is just to divide
33/3
which gets you the answer of 11
but here is another way to explain this
3x = 33
since the 3 and the x are times/multiplying each other and we need to get x by its self, all we do is move the 3 to the other side ( where 33 is ) but instead of multiplying them, we have the change the sign to dividing
3x = 33
/3 ----|>
( dont forgot to rewrite the equation!! )
x = 33/3
now all we need to do is divide 33 by 3 which gives us the answer of
11
hope this helps you! and if you ever need anymore help of problems like theses, just ask me :)

I don’t get this can someone explain please
Answer:
2^4/4^2 will be 1, I will explain after answering,
2 x 3^1 = 6
(4 - 2) ^2 = 4
First. Evaluate the exponents in the fraction above
2 x 2 x 2 x 2 = 16
4 x 4 = 16
and 16 over 16 would equal 1 whole
3 to the power of 1 means just 3 so 2 x 3 = 6 (easy multiplication)
Evaluate in the parenthesis first: 4 - 2 = 2 then 2 to the power of 2 would be 2 x 2 = 4

What does the Elimination method look like? what is the strategy?
Answer:
the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.

Complete question :
Jelena has a piece of fabric in the shape of a parallelogram the height is 10 feet and its base is 16 feet because the fabric into four equal parallelograms by current base and the height in half what is the area of each new parallelogram?
Answer:
40 ft²
Step-by-step explanation:
Given that:
Height = 10 feets
Base = 16 feets
Area of parallelogram = height * base
Area of parallelogram = 10 * 16 = 160 ft²
Area of each new parallelogram :
Area of parallelogram / number of divisions
= 160ft² / 4
= 40 ft²
