A pair of equations is shown below:
y = 7x − 8
y = 5x − 2
Part A: Explain how you will solve the pair of equations by substitution or elimination. Show all the steps and write the solution.
Part B: If the two equations are graphed, at what point will the lines representing the two equations intersect? Explain your answer
Answer:
x = 3
(3, 13)
Step-by-step explanation:
Given equations:
y = 7x − 8y = 5x − 2Part ASolve by substitution:
⇒ y = y
⇒ 7x - 8 = 5x - 2
Subtract 5x from both sides:
⇒ 7x - 8 - 5x = 5x - 2 - 5x
⇒ 2x - 8 = - 2
Add 8 to both sides:
⇒ 2x - 8 + 8 = - 2 + 8
⇒ 2x = 6
Divide both sides by 2:
⇒ 2x ÷ 2 = 6 ÷ 2
⇒ x = 3
Part BTo find the y-value of the point of intersection, substitute the found value of x (from part A) into one of the equations:
⇒ y = 7(3) - 8
⇒ y = 21 - 8
⇒ y = 13
Therefore, the point at which the lines intersect is (3, 13)
cassie is placing stickers on a page that is 12 inches long and 8 inches wide the sticker are 3 inches long and 2 inches wide
Answer:
To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.
Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).
Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).
To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
First, find out how much stickers you can put on the long side:
12/3 = 4
Next, find out how much stickers you can put on the wide side:
8/2 = 4
Lastly, calculate them together:
4x4=16
So the answer is 16.
help!! its a part A and part b question
(don't mind my answer for A I pressed it by accident)
Answer:
2cm is 5km
Step-by-step explanation:
16cm is 40km
Answer: 4e+6 centimeters
Step-by-step explanation:
Multiply the length value by 100000 and you'll get your answer.
40x100000= 4e+6 (Multiplied by length value).

PLS HELP ! Solve the addition equation by finding a common multiple. one half + two thirds + four sixths equals ___
Answer: 1/2 + 2/3 + 4 /6 = 11/6
Step-by-step explanation:
1/2 + 2/3 + 4 /6
We need to find a common multiple, for the denominator. Let us choose 6, so we do not have to deal with large numbers.
Note that we do not change 4/6, since it already has a denominator of 6.
==> 3/6 + 4/6 + 4/6
Add;
==> 11/6
3/6 + 4/6 + 4/6 equal to 11/6

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

Find the slope of the line that passes through the pair of points (10/17,2/17) and (9/17,13/18) a.-18/185 b. -185/18
Answer:
b) -185/18
Slope of the line \(m = \frac{-185}{18}\)
Step-by-step explanation:
Explanation:-
Given two co-ordinates are
\((\frac{10}{17} , \frac{2}{17} ),(\frac{9}{17} , \frac{13}{18} )\)
Slope of the line
\(m = \frac{y_{2} - y_{1} }{x_{2} - x_{1} }\)
\(m = \frac{13/18 - 2/17 }{9/17 - 10/17 }\)
\(m = \frac{\frac{221-36}{18 X 17} }{\frac{-1}{17} }\)
On simplification, we get
\(m = \frac{-185}{18}\)

Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.
