A.
Step-by-step explanation:
To find out the answer, there is a method that can be used to find out if a line is a function. It is called the vertical line method. And it also has to be per x, One y value has to be there. Analyzing the graphs, the answer should be option A.
solving systems of equations in three variables
Answer:
A: (x = 34, y = -27, z = -1)
Step-by-step explanation:
Plug the variables in. It might be tedious, but it guarantees you get it right.
Let's try A first. 2(34) + 2(-27) + 6(-1) = 8. Is this correct? Yes. However, you gotta plug it in for the other three equations. 5(34) + 6(-27) + 5(-1) = 3. Is this correct? Yes again. One last equation. 5(34) + 6(-27) + 3(-1) = 5. That's correct as well. The answer is A.
In case you still weren't sure if the answer was A or not;
B: 2(33) + 2(-26) + 6(0) = 14. Right away we can see that B will be incorrect.
C: 2(35) + 2(-28) + 6(-2) = 2. Again, incorrect.
D: 2(36) + 2(-29) + 6(1) = 20. Incorrect!
A is the correct answer.

Joanie earns $12 per hour, plus a $20 bonus completing the training program. This week Joanie earned $240. Write an equation to represent this situation.
Answer:
(12+20)x=240
Step-by-step explanation:
x=number of hours
If she earns $12 per hour and a $20 bonus you divide that from 240 to get the number of hours she worked.

Answer: first and third choice
Step-by-step explanation:
it would be the first and third choices. the first choice employs the distributive property— it distributes b to x and c.
the third choice performs opposite operations. so instead of multiplying b by (x+c) it does the opposite and divides it by both sides

Answer:
1 Meter equals 100 Centimeters, therefore 1 Square meter is equal to 100 centimeters squared. Thus, [tex]1 M^{2}[/tex] is equal to [tex]100^{2}[/tex] when counting in Centimeters square. Now that we have gotten the basics down, Lets convert the other necessary units.
[tex]1 m^{2} = 10,000 cm^{2}[/tex]
[tex]1 mm^{2} = 0.01cm^{2}[/tex]
[tex]1 km^{2} = 1,000,000 m^{2}[/tex]
Now, using that knowledge, we can find the answers to all questions.
1) 0.15 [tex]m^{2}[/tex]
2) 0.086 [tex]m^{2}[/tex]
3) 0.1 [tex]cm^{2}[/tex]
4) 600,000 [tex]cm^{2}[/tex]
5) 0.0001 [tex]km^{2}[/tex]
6) 400 [tex]cm^{2}[/tex]
7) 52,100 [tex]mm^{2}[/tex]
8) 500,000 [tex]m^{2}[/tex]
9) 0.087 [tex]mm^{2}[/tex]

7(x+2)-5(x+3=9(4-x)
Answer:
x = 37/11
Step-by-step explanation:
7(x + 2) - 5(x + 3) = 9(4 - x)
=> 7x + 14 - 5x - 15 = 36 - 9x
=> 2x - 1 = 36 - 9x
=> 11x = 37
=> x = 37/11

chip and dip magazines ratio of men to women subscribers is 5 to 8 if they have 75000 women how many men
Answer:
46875
Step-by-step explanation:
Men :Women = 5 : 8
Total parts = 5+8 = 13
Total number be x
[tex]\dfrac{8}{13}*x = 75000\\\\\\x =75000*\dfrac{13}{8}\\\\\\x = 121875[/tex]

Convert
1.8125 gallons to cups
Answer: 1.8125 gallons = 29 cups
Step-by-step explanation:
There are 16 cups in a gallon. Therefore, to convert gallons to cups we multiply the number of gallons by 16.
The number of gallons, in this case, is: 1.8125
So, we need to multiply 1.8125 by 16
1.8125 ⋅ 16 = 29
In the final analysis, 1.8125 gallons is equal to 29 cups.

I'm stuck on question 6 + (-20.5)
Answer:
Step-by-step explanation:
First you put the negative sign away for the end and then you switch the problem to 20.5 - 6. Then you put the 0.5 away for later too. 20 - 6 is equal to 14. Then you add the 0.5 back to the number. So it is equal 14.5 and the you put the negative sign back on to get the final answer of -14.5.
One thousand families were surveyed to
determine the distribution of families by size. The
results follow.
Family Size 2
3
4
5 6 7 8
Frequency
350
200 245 125
66
10
To the nearest percent, the probability that a given
family has 3 people is [? ]%.
Answer:
Step-by-step explanation:
probability of an event: number of events that satisfy the criteria/ total number of events
number of events that satisfy the criteria (in this case the number of families with three people)= 200
total number of events= 1000
200/1000= 20%

you are given a fraction in simplest form. the numerator is not zero.when you write the fraction as a decimal,it is a repeating decimal. which numbers from 1 to 10 could be the denominator
Answer:
3, 6, 7, 9
Step-by-step explanation:
We can take a look at each value from 1 to 10
We see that for 3, 6, 7, and 9 the decimal repeats forever for some numerators. For example, 1/3 repeats forever, 4/6 repeats forever, 5/7 repeats forever, 1/9 repeats forever.
_ please answer this question .
Answer:
For the column "Slope Intercept", the graph is displaying y = -7/2x + 3. Because the line is going down 7 units and to the right 2 units, and the 3 is the point in which the line crosses the y-axis.
For the "Standard" column, it will be
7x + 2y = 6, because that's what it would look like in standard form. (To turn it from standard to slope intercept form, remember you must first subtract 7x on both sides to get 2y = -7x + 6, and then divide by 2 on both sides to get
y = -7/2x + 3.)
For column "Point Slope", I just realized you are supposed to pick a point on the line and plug the coordinates into this formula:⤵⤵⤵
This is the point-slope formula.⤵⤵⤵
[tex]y - y _{1} = m(x - x _{1})[/tex]
For example we'll use point (2,-4). Also, remember that coordinates are written as (x,y), and that m represents slope.
So we have: y - (-4) = -7/2(x-2).
In other words, "Point Slope" would be
y + 4 = -7/2(x-2).
By the way, sorry this is a bit long, and took a while to complete. I had to re-educate myself on point-slope. Anyways hope this helps, I tried :)

Jerry eats one-fourth of a pecan pie. Sally eats
one-fifth of the same pie. Rose comes home from
school and eats two-tenths of the same pie. How
much of the pie has been eaten?
Answer:
13/20 or .65
Step-by-step explanation:
1/4 + 1/5 + 2/10 = Total amount eaten
Find a common denominator is 20
1/4 = 5/20
1/5 = 4/20
2/10 = 4/20
13/20
ssion 4 x (20 – 1) if a = 3?
What the answer?
Answer:
20Step-by-step explanation:
Question:4 × (2a - 1)
Given value:a = 3
Solution:4 × (2a - 1)
= 4 × (2(3) - 1) [Substituting the value of a=3]
= 4 × (6 - 1) [Simplification]
= 4 × 5 [On further simplification]
= 20
Hence, 20 is the required answer.
Answer:
20
Step-by-step explanation:
a = 3
4 × (2a - 1) =
= 4 × (2 × 3 - 1)
= 4 × (6 - 1)
= 4 × 5
= 20

The hypotenuse of a right triangle measures 9 cm and one of its legs measures 4 cm. Find the measure of the other leg.
Answer:
The other leg is √65 cm
Step-by-step explanation:
Hi there!
We are given that the hypotenuse of a right triangle measures 9 cm, and one of the legs measures 4 cm
We want to find the measure of the other leg
In right triangles, we can use the theorem to find the value of a side, if we know the lengths of the other two sides
The formula for the Pythagorean theorem is a²+b²=c², where a and b are legs, while c is the hypotenuse
If we say a is 4 and c is 9, then the equation will look like this:
(4)²+b²=(9)²
Raise each number to the second power
16 + b²= 81
Subtract 16 from both sides
b²=65
Take the square root of 65
b=√65, -√65
-√65 is not an applicable root for this problem, since distance cannot be negative
Hence, our answer is √65 cm
Hope this helps!
