Choose the graph that solves this system of equations.
y = 2x – 6
y = –4x + 3
Two lines that intersect at the origin. One line has a positive slope and the other has a negative slope. Two lines that intersect at about 2 comma negative one half. One line has a positive slope and the other has a negative slope. There is also a single dot at the origin. Two lines that intersect at about three halves comma negative 3. One line has a positive slope and the other has a negative slope. Two lines that both have a positive slope. They do not intersect on the part of the graph shown, but there is a single dot at the origin.
Answer: Two lines that intersect at about three halves comma negative 3. One line has a positive slope and the other has a negative slope.
Step-by-step explanation:
Given equations of line:
y = 2x – 6 ...(i)
y = –4x + 3 ...(ii)
On comparing with y=mx+c (slope-intercept form), where m= slope ,= y-intercept.
(i) has positive slope (2) and (ii) has negative slope(-4).
Eliminate (ii) from (i), we get
0 = 6x-9
⇒ 6x=9
⇒ [tex]x=\dfrac32[/tex]
Put value of x in (i), we get
[tex]y=2(\dfrac32)-6\\\\\Rightarrow\ y=3-6=-3[/tex]
Point of intersection = (three halves, negative 3)

Sariyah cuts 22 yards of cloth into 8 pieces of equal length the lengths of each pieces falls between two measures
Answer:
1 piece of equal length = 2 3/4 yards of cloth
Step-by-step explanation:
Sariyah cuts 22 yards of cloth into 8 pieces of equal length the lengths of each pieces falls between two measures
8 pieces of equal length = 22 yards of cloth
1 piece of equal length = x yards
Cross Multiply
8 pieces × x yards = 22 yards × 1 piece
x yards = 22 yards/8
x yards = 11/4
x yards = 2 3/4 yards
Therefore, 1 piece of equal length = 2 3/4 yards of cloth

Because 0 repeats
The answer is C, because the 0 repeats itself in C and in a function, X does NOT repeat. And in this case, X is 0, which repeats.

What is the geometric mean between 3 and 10
Answer:
So for the geometric mean, you would multiply the two numbers and put them under a radical
Step-by-step explanation:
3 times 10= 30
=[tex]\sqrt{30}[/tex]
The solution is : the geometric mean between 3 and 10 is √30.
What is geometric mean?The Geometric Mean (GM) in mathematics is the average value or mean that, by calculating the product of the values of the set of numbers, denotes the central tendency of the numbers. In essence, we multiply the numbers together and calculate their nth root, where n is the total number of data values.
here, we have,
Given: two numbers 3 and 10
we have,
To Find: Geometric number of numbers in 3 and 10
Solution:
Let first number be a

Step-by-step explanation:
y = 12(x)+28
(-1,16)
y = 12(-1)+28 = 16
(5,88)
y = 12(5)+28 = 88
Answer:
We conclude that the function [tex]f(x) = 12x + 28[/tex] works.
The graph of the function y = 12x + 28 is also attached below.
Step-by-step explanation:
Given that the line passes through the points
(-1, 16)(5, 88)Let us determine the slope between (-1, 16) and (5, 88) using the slope formula
[tex]\mathrm{m}=\frac{y_2-y_1}{x_2-x_1}[/tex]
where m is the slope between (x₁, y₁) and (x₂, y₂)
In our case:
(x₁, y₁) = (-1, 16)(x₂, y₂) = (5, 88)so subtituting (x₁, y₁) = (-1, 16) and (x₂, y₂) = (5, 88) in the slope formula
[tex]\mathrm{m}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{88-16}{5-\left(-1\right)}[/tex]
Refine
[tex]m=12[/tex]
Thus, the slope of the line is: m = 12
Important Tip:
The slope-intercept form of the line equation is
[tex]y = mx + b[/tex]
where m is the slope and b is the y-intercept
now substituting m = 12 and the point (-1, 16) in the slope-intercept form of the line equation
[tex]y = mx + b[/tex]
[tex]16 = 12(-1) + b[/tex]
switch the equation
[tex]12(-1) + b = 16[/tex]
[tex]-12 + b = 16[/tex]
Add 12 to both sides
[tex]-12+b+12=16+12[/tex]
Simplify
[tex]b=28[/tex]
Thus, the y-intercept of the line is: b = 28
now substituting m = 12 and b = 28 in the slope-intercept form of the line equation
[tex]y = mx + b[/tex]
[tex]y = 12x + 28[/tex]
Thus the equation of the line is:
[tex]y = 12x + 28[/tex]
or
[tex]f(x) = 12x + 28[/tex] ∵ [tex]y = f(x)[/tex]
Hence, we conclude that the function [tex]f(x) = 12x + 28[/tex] works.
The graph of the function y = 12x + 28 is also attached below.

Hi there!
I don’t know how to properly answer step 1, but it looks like you already have the formula written down.
For step 2, divide 120 by 3 to find how many backpacks made in one hour, or 40 backpacks per hour.
600 backpacks = 40 backpacks/1 hour * t
Step 3: This may look complicated, but i promise it is not. All we have to do here is divide 600 by 40, or 15.
t = 15, or it will take 15 hours to make 600 backpacks.
I hope this helps!
solve the inequality -2z - 3 < 5
-2z - 3 < 5 inequality is solved to z>-4.
What is Inequality?Relationship between two expressions or values that are not equal to each other is called 'inequality.
The given inequality is -2z - 3 < 5
Minus two times of z minus three less than five.
-2z - 3 < 5
We need to solve this inequality, which means we need to solve of variable z.
Add 3 on both sides of inequality
-2z<8
Divide both sides by 2
-z<4
Multiply the given inequality by minus
z>-4
Hence, -2z - 3 < 5 inequality is solved to z>-4.

Evaluate and simplify the following complex fraction.
=========================================================
Explanation:
The fraction 6/(-7) is the same as -6/7
We have the two fraction -6/7 and 3/11 being divided
The denominators are 7 and 11 respectively.
The LCM of those two numbers is 77 since 7*11 = 77
If we multiply each of those fractions (-6/7 and 3/11) by 77, then we'll clear out those inner denominators to simplify this complex fraction into a nicer one.
77*(-6/7) = -66
77*(3/11) = 21
This means the original complex fraction becomes -66/21
We can further simplify this by dividing each part by the GCF 3
-66/3 = -22
21/3 = 7
Therefore, the final answer is -22/7

A box is filled with 9 red crayons, 5 blue crayons, and 8 yellow crayons. A crayon is chosen at random from the box. Find the probability that it is a blue or a yellow crayon. Write your answer as a fraction in simplest form.
Answer: 13/22
Step-by-step explanation:
Number of red crayons = 9
Number of blue crayons = 5
Number of yellow crayons = 8
Total number of crayons = 9+5+8 = 22
The probability of selecting either ia blue or a yellow crayon will be:
= 5/22 + 8/22
= 13/22
There are 4 white marbles, 6 red marbles, and 2
blue marbles. Once a marble is selected, it is not
replaced. Find the probability of selecting 2 blue
marbles.
Answer:
For first question, there is 12 marbles at first. So the probability of choosing blue marble is 3/12=1/4. Then marbles are not replaced, the total number is 11. The probability of choosing red is 5/11. So the finally answer is (1/4)*(5/11)=5/44. The same method for second question. Need to notice that you have already choose 1 white marble, so the number of white marble also changed. The answer is (4/12)*(3/11)=1/11.
Step-by-step explanation:
The probability of selecting 2 blue marbles without replacement will be 1/66.
What is probability?Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.
There are 4 white marbles, 6 red marbles, and 2 blue marbles.
Once a marble is selected, it is not replaced.
Then the total number of the marbles will be
Total marbles = 4 + 6 + 2
Total marbles = 12
Then the probability of selecting 2 blue marbles without replacement will be
P = 2/12 x 1/11
P = 2/132
P = 1/66
