Step-by-step explanation:
Which value or values for the variable x from the set below will make 4.5 + 1.2x ≥ 10 - x true? {3, 4, 5, 6}
1. only 3
2. 3 and 4
3. 3,4, and 5
4. all values in the set
Answer:
Option 4 is correct option.
Step-by-step explanation:
We need to find the value for the variable x from the set {3,4,5,6} below will make [tex]4.5 + 1.2x \geq 10 - x[/tex] true
First we solve the inequality to find values for x
[tex]4.5 + 1.2x \geq 10 - x[/tex]
Adding x on both sides
[tex]4.5 + 1.2x+x \geq 10 - x+x\\4.5+2.5x\geq 10[/tex]
Subtracting 4.5 from both sides
[tex]4.5+2.5x-4.5\geq 10-4.5\\2.5x\geq 5.5\\[/tex]
Divide both sides by 2.5
[tex]\frac{2.5x}{2.5} \geq \frac{5.5}{2.5}\\x\geq 2.2[/tex]
So, after solving inequality we get x ≥ 2.2
So, all values greater than 2.2 can be considered true. In the set given {3,4,5,6} all values are greater than 2.2 so all values in the set are considered true for [tex]4.5 + 1.2x \geq 10 - x[/tex]
Option 4 is correct option.

The required simplified solution of the given expression is given as x = 1 ± √2.
Given that,
To determine the simplified solution of the given expression (x + 1)² – 4(x + 1) + 2 = 0.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
here,
Given expression, (x + 1)² – 4(x + 1) + 2 = 0
Substitute x + 1 = u in the above equation,
u² - 4u + 2 = 0
u² - 4u +4 - 4 + 2 = 0
(u - 2)² = 2
u - 2 = ±√2
substitute u = x + 1
x + 1 - 2 = ±√2
x - 1 = ±√2
x = 1 ± √2
Thus, the required simplified solution of the given expession is given as x = 1 ± √2.

Are the lines through the pairs of points parallel, perpendicular, or neither?
(-3, 1) and (2, 3)
(-3, 5) and (-1, 0)
Answer: The lines through the pairs of points are perpendicular.
Step-by-step explanation: The lines when graphed do not have the same slope so they can not be parallel. However, when graphed the points (-3, 5) and (-1, 0) goes through the midpoint of the points (-3,1) and (2,3) meaning that the above points are perpendicular! Hope this makes sense and helps.

Is the relation shown in the table below a function? Explain.
Answer
No
Step-by-step explanation:
it is not a function because 9 and three are a pair but so are 27 and 3. that makes it not a function
No, the given relation is not a function. A function is a connection between inputs in which each input is connected to precisely one output.
What is a function?A function is a relationship between a number of inputs and outputs. A function is an association of inputs where each input is coupled with exactly one output. There is a range, co-domain, and domain for every function.
Given, a table where points are denoted as inputs and outputs.
To prove the relation is a function:
A relation between a collection of inputs and outputs is known as a function.
A function is a connection between inputs in which each input is connected to precisely one output.
But here, input value of 3 have two outputs.
Which gives us contradiction.

Three types of tickets for a football game are available: sidelines, goal-view, and upper-deck. The sidelines tickets cost $25 more than the goal-view tickets and $50 more than the upper deck tickets. The goal-view tickets cost $13 less than twice the cost of the upper-deck tickets. Determine the price of each type of ticket.
Answer:
Upper deck = $38
Goal View = $63
Sidelines = $88
Step-by-step explanation:
Represent
- Sidelines with S
- Goal-view with G
- Upper-deck with U
We have that:
[tex]S = 25 + G[/tex]
[tex]S = 50 + U[/tex]
[tex]G = 2U - 13[/tex]
Required
Solve for S, G and U
Substitute 25 + G for S in the second equation
[tex]25 + G = 50 + U[/tex]
Make G the subject
[tex]G = 50 -25+ U[/tex]
[tex]G = 25+ U[/tex]
Substitute 25 + U for G in the third equation
[tex]25 + U = 2U - 13[/tex]
Collect Like Terms
[tex]U - 2U = -13 - 25[/tex]
[tex]-U = -38[/tex]
[tex]U = 38[/tex]
Substitute 38 for U in [tex]G = 25+ U[/tex]
[tex]G = 25 + 38[/tex]
[tex]G =63[/tex]
Substitute 63 for G in [tex]S = 25 + G[/tex]
[tex]S = 25 + 63[/tex]
[tex]S = 88[/tex]

8/3 is an improper fraction and should be written as 2 2/3.
Pedro and Rebecca were trying to solve the equation: 0.1x^2-0.7x+1.2=0. Pedro said, “I can multiply the entire equation by 10 and then factor. Then I can solve using the zero product property.” Rebecca said, “I'll solve using the quadratic formula with a=0.1, b=-0.7, c=1.2.” Whose solution strategy would work?
Answer:both
Step-by-step explanation: I take it on khan and I get it right!
Both methods will work, but Rebecca's one is harder than Pedro's method.
Whose solution strategy would work?
Pedro wants to multiply the whole equation by 10, so he can work with whole numbers which is easier, while Rebecca prefers to just use Bhaskara's formula with the given coefficients.
With that in mind, neither method has a problem, so both will work fine. The only problem that could come is that for Rebbeca, when she wants to evaluate the square root in the Bhaskara's formula, she will get:
[tex]\sqrt{(-0,7)^2 - 4*0.1*1.2 } = \sqrt{0.01}[/tex]
And that is kinda impossible to compute by hand, but if she has a calculator, everything is fine.
Then we conclude that both methods will work.
