The variable is the main part, it is the base of the whole thing that shows all the critical points for the inequality ? , x = 1, and x = 2 x = –6 and x = 2 x = –4 and x = 2 x = 2.
How do you find the critical points of an inequality?Solve a rational inequality.
Determine the critical points–the points where the rational expression will be zero or undefined. Use the critical points to divide the number line into intervals. Test a value in each interval. Above the number, the line shows the sign of each factor of the rational expression in each interval.
How do you find the critical points of a function?To find the critical points of a function y = f(x), just find x-values where the derivative f'(x) = 0 and also the x-values where f'(x) is not defined. These would give the x-values of the critical points and substituting each of them in y = f(x) will give the y-values of the critical points.

pure antifreeze. The company wants to obtain
320
gallons of a mixture that contains
55

pure antifreeze. How many gallons of water and how many gallons of the premium antifreeze solution must be mixed?
Answer:
let w = amt of water required
:
An equation based on the the percent water, an 80% solution is 20% water.
.20(320-w) + w = .50(320)
64 - .2w + w = 160

A linear system is classified as inconsistent. Choose True or False for the statement about the graph of the system.The slopes of the lines are the same.
Answer: true
Step-by-step explanation:
A system of linear equations can be written as:
y = a*x + c
y = d*x + f
Now, the idea of this is find the point (x, y) where both linear equations meet.
Particularlly, if the slope in both equations is the same, we will have two options:
1) The lines are parallel, so they never met, and the system has no solution.
2) The lines are the same lines (this happens when c = f) and this means that we have infinite solutions.
So it is true, if the slopes are the same, the linear system is not consisten.

Triangular prism area: A = 1/3 * base area * height
= 1/3 * 12 * 19
= 76 cm²
Rectangular prism: A = base area * height
= 8 * 15
= 120 cm²
The rectangular container has a better value because it has a bigger area and is cheaper.

(29 + 9)2
Answer:
[tex](40-2)^2[/tex]
Step-by-step explanation:
Given: [tex](38)^2[/tex]
To find: the correct option
Solution:
A binomial polynomial is a polynomial consisting of two terms.
A trinomial polynomial is a polynomial consisting of three terms.
On multiplying a binomial [tex](x-y)[/tex] to itself, a perfect square trinomial [tex](x-y)^2[/tex] is obtained.
Here, [tex]38=40-2[/tex]
So, [tex](38)^2=(38)(38)=(40-2)(40-2)=(40-2)^2[/tex]
Here, [tex](40-2)[/tex] is a binomial and it is multiplied to [tex](40-2)[/tex] to get a perfect square trinomial [tex](40-2)^2[/tex]
Answer:
(40 − 2)^2
Step-by-step explanation:
(First just do simple math to narrow down your choices)
A: (40 − 2)^2
40 - 2 = 38
B: (40 + 2)^2
40 + 2 = 42
C: (29 − 9)^2
29 - 9 = 20
D: (29 + 9)^2
29 + 9 = 38
(Now you just have A and D)
A: (40 − 2)^2
D: (29 + 9)^2
(Determine which properly expresses a Perfect Square Trinomial)
A: (40 − 2)^2

Find the interest on $4,500 at 5.2% for 2 and a half years. Which of the following equations would be used to solve this problem?
Please help!
A: 4500 = P(0.052)(2.5)
B: I = (4500)(5.2)(2.5)
C: I = (4500)(0.052)(2.5)
D: I = (4500)(0.52)(2.5)
The equations used to solve this problem is I = (4500)(0.052)(2.5).
The correct option is (C).
What is Interest?Simple interest is a loan interest payment that borrowers pay to lenders. It is based solely on the principal and does not account for compounding interest. Straightforward interest is not limited to certain loans. It is also the form of interest that banks pay on savings accounts.
Given:
P = $4500
R= 5.2%
Time= 2 and half year
Using the formula of Simple Interest
= P x R x T / 100
= (4500 x 5.2 x 2.5)/ 100
= (4500 x 0.052 x 2.5)
= $585
So, the equation is: : I = (4500)(0.052)(2.5)

Maya can run 18 miles in 3 hours, and she can bike 18 miles in 2 hours.
c
Maya biked for 3 hours and then ran for 1 hour and 30 minutes. What distance did she cover?
Answer:
36
Step-by-step explanation:
if it is two hours then half of it is 9
so 18 + 9 = 27 which is how many miles she biked
6 is the number of miles she ran
so u times it by 1.5
27 + 9 = 36
Answer:
36 miles
Step-by-step explanation:
Her running speed is 6 mph and her biking speed is 9 mph (from part a and b)
she biked for 3 hours so multiply that by 9 (biking speed) to get 27
she also ran for an 1.5 hours so multiply that with 6 (running speed) to get 9
27+9=36

Answer:
k = 5,
y = 5x
Step-by-step explanation:
If y is proportional to x,
y ∝ x
Then the equation will be
y = kx
Her k = proportionality constant.
Now we choose a point from the given table.
Let the point is (2, 10).
By putting the values of x and y in the equation,
10 = 2×k
k = [tex]\frac{10}{2}[/tex]
k = 5
This will be true for any point we choose from the table.
And the equation will be y = 5x

Find two numbers, if their sum is 97 and their difference is 7.
Answer:
Step-by-s tep explanation:
Answer:
Step-by-step explanation:
Let m and n represent the numbers. Then m + n = 97 and n - m = 7.
Solving the second equation for n, we get n = m + 7. Substituting m + 7 for n in the first equation we obtain:
m + (m + 7) = 97, or
2m + 7 = 97, or 2m = 90
Dividing both sides by 2, we get m = 45. Then n must be 52.
