Consider the following pair of equations:
y = x + 4
y = - 2x - 2
Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form. (20 points!)
Answers
Answer:
(-2, 2).
Step-by-step explanation:
y = x + 4
y = - 2x - 2
Substitute y = x + 4 in the second equation:
x + 4 = -2x - 2
x + 2x = -2 - 4
3x = -6
x = -2.
Now substitute x = -2 in the first equation:
y = -2 + 4 = 2.
Check the results by substituting for x and y in equation 2:
2 = -2*-2 - 2 = 4 - 2 = 2. - this checks out.
Answer:
(-2, 2).

which of the following cannot be the graph of a function of X?
Answers
Why not? Because it fails the vertical line test. Here it is possible to draw a single straight vertical line through more than one point on the curve. That's why choice D is not a function. Choices A,B,C are functions because it's impossible to draw a single vertical line through more than two points on the curve, and therefore we can say they pass the vertical line test.
Side note: choices B and C fail the horizontal line test, so these functions are not one-to-one.

If a line plot were to be made, the number of "X"s placed above the 2 would be ____
above the 3 would be
____
above the 4 would be _____
and above the 5 would be
_____.
Answers
Answer:
No. X's above 2: 1
Above 3: 1
Above 4: 3
Above 5: 3
Step-by-step explanation:
Drawing a line plot of a data set means that you record the number of times that particular value shows up in the set. 2 on the line plot would only have 1 'X' placed above it because there is only one 2 in the data set:
5, 5, 4, 3, 2, 5, 4, 4
3 would also have 1 'X' above it because there is also only one 3 in the data set:
5, 5, 4, 3, 2, 5, 4, 4
Similarly, 4 and 5 would both have three 'X's because there are three 4's and three 5's in the data set:
4's: 5, 5, 4, 3, 2, 5, 4, 4
5's: 5, 5, 4, 3, 2, 5, 4, 4

There are 8 sweets in a box. There are n jelly beans and the rest are cola bottles. Colin takes 2 sweets out of the box at random. Write an expression for the probability of getting 2 cola bottles. Give your expression as a single fraction and simplify fully.
Answers
Answer:
Probability expression = 1 - n/7 - n/8 + n^2 / 56
Probability single fraction based on example = 3/28
Step-by-step explanation:
Total sweets = 8. n jelly beans , 8 - n cola bottles
Prob (getting 1st cola bottle) = Cola bottles / Total sweets = (8-n) /8
Prob (getting 2nd cola bottle) = remaining cola bottles / remaining total sweets = (8 - n - 1) / (8-1) = (7-n) / (7)
Prob (getting both 1st & 2nd cola bottle) = [ (8-n) /8 ] x [ (7-n) / 7 ]
(1 - n/8) x (1-n/7) = 1 - n/7 - n/8 + n^2 / 56
Eg : 5 jelly beans , 3 cola bottles
Similarly, Prob (2 cola bottles) = 3/8 x 2/7 = 6 / 56 = 3/28

Please define (provide the meaning) the following forms of rocks:

2. Sedimentary Rocks
3. Metamorphic Rocks
Answers
Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water. Most rocks are made of minerals containing silicon and oxygen, the most abundant elements in the Earth’s crust.

The width of a triangle of 7 feet longer than its length. Find the dimensions of the rectangle such that the perimeter of the rectangle is 162 feet
Answers
Answer:
Length = 37 feets
Width = 44 feets
Step-by-step explanation:
Given that :
Length = l
Width, w = 7 + l
Perimeter , P of rectangle = 162
Recall:
Perimeter of a rectangle = 2(l + w)
P = 2(l + w)
162 = 2(l + (7 + l))
162 = 2(l + 7 + l)
162 = 2(7 + 2l)
162 = 14 + 4l
162 - 14 = 4l
148 = 4l
l = 148 / 4
l = 37 feets
Width = l + 7
Hence,
Width = 37 + 7 = 44 feets

Compound Interest = 9680
Step-by-step explanation:
The formula of Compound Interest: [tex]A = P(1 + \frac{r}{n} )^n^t[/tex]
Where;
A = Compound Interest
P = Principal amount
r = Rate of interest
n = amount of deposite annually
t = total time
Therefore:
[tex]A = 8000(1 + \frac{0.08}{1})^1^*^2^.^5[/tex]
[tex]A = 8000(1 + 0.08)^2^.^5[/tex]
[tex]A = 8000(1.08)^2^.^5[/tex]
A = 8000(1.21)
A = 9680
Therefore, the compound interest = 9680

If the mean of the data below is 3.8, find m
x 1 2 3 4 5 6
f 1 4 7 m 6 3
Answers
Answer:
m = 1.8
Step-by-step explanation:
Given data is as follows :
x 1 2 3 4 5 6
f 1 4 7 m 6 3
We need to find the value of m if the mean of the data is 3.8.
Mean = sum of observations/no. of observations
So,
[tex]3.8=\dfrac{1+4+7+m+6+3}{6}\\\\22.8=21+m\\\\22.8-21=m\\\\m=1.8[/tex]
So, the value of m is equal to 1.8.
