Which graph shows only a direct variation between X and y?
Answer:
A
Step-by-step explanation:
Direct variation graphs always intersect the origin. Therefore, graph A is accurate.
Identify the slope and y-intercept of the line on the graph. Then, write the equation of the line in slope intercept form. I need all of the answers (all 9 - 12). It'd help me a lot. Thanks.
Answer:
9: Slope is 2/5 and y-intercept is -3
Equation: y=2/5x-3
10: Slope is 1 and y-intercept is -6
Equation: y=x-6
11: Slope is -1/4 and y-intercept is 5
Equation: y=-1/4x+5
12: Slope is 4/3 and y-intercept is 0
Equation: y= 4/3x + 0

Evaluate each expression for the given value of the variable
1. 38.1+x for x=-6.1
2. 18.7+x for x=8.5
3. 8/15+x for x=-4/15
4. 13/20+x for x=4/20
5. 21.6+ x for x=-11.2
6. 8/13+x for x=2/13
please help me this is due today
Answer:
Step-by-step explanation:
This problem is asking you to substitute for x.
1. 38.1 + x when x=-6.1
It is giving you what the value of x is, -6.1.
Substitute
38.1 - 6.1
=32
When ever it says x =
That number replaces x and then you solve.
2. 18.7 + x x = 8.5
18.7 + 8.5
27.2
Do this for the rest of the problems.
Hope this helps!!!
help me pleaseeeeeeeeeeeeee
Answer
(2,3)
Step-by-step explanation:
9x-7y=-3
-9x+15y=27
-------------------
8y=24
divide by 8 on both sides
y=3
now using substitution, you can now work out x
9x-7y=-3
9x-7(3)=-3
9x-21=-3
add 21 on both sides
9x=18
then divide my 9 on both sides
x=2

What is the number that has a value 10 times the value of 0.009? Please Explain.
Answer:
Step-by-step explanation:
I don’t know
Answer:
0.09
Step-by-step explanation:
From what I'm understanding you have to use powers of 10. Here's how they work:
All you do is move the decimal point, I know that may sound weird but let me explain.
When we are working with powers of 10 you just multiply the number by 10.
10 x 0.009
Now instead of having to type that into a calculator, or working it out, you can just move the decimal point to the right or the left.
Here's how I remember it:
Multiplying- move it to the right so the number can get bigger
Dividing- move it to the left so the number gets smaller
The number of zeros (0) you have after the one determines how many times you move the decimal point.
100- move the decimal point twice
100000- move the decimal point 5 times
In this case you are multiplying and moving the decimal point to the right once. There is one zero in the number and the problem asks you to multiply.
0.009
= 0.09
You move the decimal point over once.
Hope this helps!!!
w-4/h-4=4/3 can someone please answer this its for homework someone told me it was 8 but i got 12
the letter "w" represents a variable, and the letter "h" also represents a variable. The goal is to solve for either "w" or "h" by using the given information and the rules of algebra.
To solve this equation, we can start by multiplying both sides of the equation by 3 to eliminate the fraction on the right side:
w-4/h-4=4/3
3(w-4/h-4)=3(4/3)
This simplifies to:
3w-12/3h-12=4
Next, we can simplify the expression on the left side of the equation by combining like terms:
3w-12/3h-12=4
3w-3h=-8
Finally, we can solve for either "w" or "h" by using the given information and the rules of algebra. For example, we can solve for "w" by adding 3h to both sides of the equation:
3w-3h=-8
3w=-8+3h
w=-2+h
This means that the value of "w" is equal to the value of "h" minus 2. Alternatively, we could solve for "h" by adding 3w to both sides of the equation:
3w-3h=-8
-3h=-8+3w
h=2-w/3
This means that the value of "h" is equal to 2 minus the value of "w" divided by 3.
These two figures are similar. Find the length of side y.

How to use a pattern to find the product of a decimal
Answer:
A decimal sequence is a set of decimals that follow each other in order, and we use a rule, or pattern, to go from one number to the next. To find the rule for a sequence, we take two consecutive numbers and subtract them.
Answer:
Step-by-step explanation:
So I don't know if this will help or is the answer that you're looking for but here:
If you're multiplying a decimal by 1, it obviously stays the same.
ex: 1 x 0.25 = 0.25
If you multiply by 10 then you move the decimal place once to the right, as it gets bigger
ex: 10 x 0.25 = 2.5
you can do this for any number:
10 x 3.44 = 34.4
you can also use any power of 10.
10^2/100
100 x 2.75 = 275/275.0
Hope this helps!!!

Allyson has 42 tables to set up for her party. The tables need to be lined up in one or more equal-sized rows. How many possible ways can the tables be lined up? (1 point)
There are 9 possible ways to line up the tables.
There are 8 possible ways to line up the tables.
There are 6 possible ways to line up the tables.
There are 4 possible ways to line up the tables.
Answer: There are 4 possible ways to line up the tables
Step-by-step explanation:
First, we need to find the factors of 42.
Factors of 42: 1, 2, 3, 6, 7, 14, 21, and 42.
Here we can see 4 pairs of numbers
1, 42
2,21
3,14

Giving 45 points
Answer:
P = 37 in
Step-by-step explanation:
since the base angles of the triangle are congruent then the triangle is isosceles with the 2 legs congruent , then
3x - 2 = 2x + 4 ( subtract 2x from both sides )
x - 2 = 4 ( add 2 to both sides )
x = 6
then
2x + 4 = 2(6) + 4 = 12 + 4 = 16
3x - 2 = 3(6) - 2 = 18 - 2 = 16
the perimeter (P) is the sum of the 3 sides , then
P = 16 + 16 + 5 = 37 in
Death Valley, California, is located 282 feet below sea level.
Which equation best represents the depth of Death Valley in feet?
Answer:
Step-by-step explanation:
Even though death valley is at -282 feet in relation to sea level, it's 282 feet away in distance. So even though the distance is in a different/negative direction, it's still an ACTUAL distance, and we call that absolute value.

(2.) 100 to 140
I'LL MARK YOU BRAINLIEST IF YOUR ANSWER IS ACCURATE!!
Answer:
1. 56.25% increase
2.40% increase
Step-by-step explanation:
V1 = 80 to V2 = 125
(V2−V1)|V1|×100
=(125−80)|80|×100
=4580×100
=0.5625×100
=56.25%change
=56.25%increase
V1 = 100 to V2 = 140
(V2−V1)|V1|×100
=(140−100)|100|×100
=40100×100
=0.4×100
=40%change
=40%increase
