Exercise 12.1
r. (1) 5x – 3 = 3x - 5
.
(1) 5y - 2[y - 3(y – 5)] = 6
Answer:
(1) x = -1 (1) y = 4
Step-by-step explanation:
r. (1) 5x - 3x = -5 + 3
2x = -2; x = -1
(1) 5y - 2[y - 3y +15] = 6
5y - 2y+6y - 30 = 6
9y = 36; y = 4

Step-by-step explanation:
12/2 = 6
[tex](x+6)^{2}[/tex] = [tex]x^{2}[/tex] +12x + 36
[tex]x^{2}[/tex] +12x + 20

What is the difference between an independent variable and a dependent variable in statistics?
Answer:
The cause is the independent variable. In your study, its value is independent of other variables. The affect is the dependent variable. Its value depends on the independent variable being changed.

Louise completed the work shown below.
(5x3 + 3)2 = (5x3)2 + (3)2 = 25x6 + 9
Determine if Louise’s answer is correct. Explain.
Answer:
SAMPLE RESPONSE
Step-by-step explanation:
Louise’s answer is not correct. She is missing the term 30x3. When squaring a binomial, it is best to write the product of the binomial times itself. Then you can use the distributive property to multiply each term in the first binomial by each term in the second binomial. Louise also could have used the formula for a perfect square trinomial, which is found by squaring a binomial.

Answer:
a) (0,0), (-4, 1), (-1,2)b) NoneStep-by-step explanation:
There are two ways of solving similar problems. One- substitute x and y with respective coordinates and verify if the inequalities are correct. Two- graph the lines and see if the points are in the intersection zones.We'll go with the first method. Remember both inequalities should be correct for the same point to accept it as a solution.Given points

Answer:
a. all points are part of the solution set
b. no points are in the solution set
Step-by-step explanation:
Graphs of the two systems of inequalities are attached.
a) The red area on the graph is the solution. The two inequalities can be combined to one compound inequality:
x -1 < y < -1/2x +2
The two boundary lines intersect at x-1 = -1/2x +2 ⇒ x = 2, so there are no points in the solution set with x-values of 2 or greater.
All of the given points are in the solution set.
__
b) The green area of the graph is the solution. Solving each inequality for y gives ...
x -2y ≥ 4 ⇒ 1/2x -2 ≥ y
2x -y ≥ -1 ⇒ 2x +1 ≥ y
The allowed values of y must be less than or equal to the minimum of these limits. The limits have the same value at 1/2x -2 = 2x +1 ⇒ x = -2, so the solution set is the area below and right of that intersection point of the two boundary lines.
None of the given points are in the solution set.

Peter has 22 coins, all dimes and quarters whose total value is $4.30 how many of each coin does he have PLEASE HELP!!!!!
Answer:
8 dimes and 14 quarters.
Step-by-step explanation:
d and q are the number of dimes and quarters, respectively.
"22 coins, all dimes and quarters"
d+q = 22
d = 22-q
"total value is $4.30"
0.10d + 0.25q = 4.30
substitution
0.10(22-q) + 0.25q = 4.30
2.2 + 0.15q = 4.30
q = 14
d = 22-q = 8
8 dimes and 14 quarters.

Answer:
In one hour Stephanie earns $1.50 more than Marco
Step-by-step explanation:
w=9h
H is a variable
9×hour= wage
9×15= $135
9×18= $162
157.50-135=$22.50
189-162=$27
27-22.50=4.50
Now cause its per hour we know she earns $4.50 more in 3 hours.
4.50÷3=$1.50
How do you graph an equation if you had m= -1/3 and b = 2.
Answer:
You first plot the point (0,2), then when the x-value of the graph increases by 3, decrease the y-value of the graph by 1, and when the x-value o the graph decreases by 3, increase the y-value of the graph by 1.
Step-by-step explanation:
The equation would be [tex]y = -\frac{1}{3}x+2[/tex]. To graph it, you first need to find the y-intercept, which is the coordinate on the line when the x-value equals 0. If x = 0, [tex]y = -\frac{1}{3}x+2[/tex] would become [tex]y = 2[/tex] since anything multiplied by 0 would become 0. Now you've located the y-intercept, which is (0, 2). The slope of a line is the coefficient of the variable x. Since the slope is a negative number, the line will go downwards as it increases its x-value and goes upward as it decreases its x-value. A slope of [tex]-\frac{1}{3}[/tex] would mean that when the x-value increases by 3, the line's y-value will decrease by 1. And when the x-value decreases by 3, the line's y-value will increase by 1. An x-value increase of 6 would be a decrease of 2, and so on. Two other obvious points on the line would be (6,0) and (3, 1).

Answer:
i think it would be around 34 feet
Step-by-step explanation:
the bottom is cut in half and each half is 8 and 1/2 feet so if you add 8 and 1/2 + 8 and 1/2 you would get 17 and then the top is rounded so you would just add 17 and 27 together to get the distance around.
