The equivalent expression is 7x - 2(1.3x + 3.5) = 5.4x - 7 and non-equivalent expression is 8 - 4(-2.2x + 1.1) = 8.8x + 12.4 .
What are linear expression ?A linear expression only has one or two variables. No variables in a linear expression is raised to power greater than 1 or used as denominator of a fraction.
Now the given expressions are,
7x - 2(1.3x + 3.5) = 5.4x - 7 ....(i)
and,
8 - 4(-2.2x + 1.1) = 8.8x + 12.4 .....(ii)
Taking equation (i)
7x - 2(1.3x + 3.5) = 5.4x - 7
So, LHS = 7x - 2(1.3x + 3.5)
⇒ LHS = 7x - 2.6x + 7
or, LHS = 5.4x + 7
⇒ LHS = RHS
So these expressions are equivalent.
Taking equation (ii),
8 - 4(-2.2x + 1.1) = 8.8x + 12.4
So, LHS = 8 - 4(-2.2x + 1.1)
⇒ LHS = 8 - 8.8x - 4.4
⇒ LHS = -0.8x - 4.4
⇒ LHS ≠ RHS
So these expressions are not equivalent.
Thus, the equivalent expression is 7x - 2(1.3x + 3.5) = 5.4x - 7 and non-equivalent expression is 8 - 4(-2.2x + 1.1) = 8.8x + 12.4.

Answer:
Step-by-step explanation:
4:C(X) = 17x - 10, the first question wants you to find how much 5 ticket costs, so replace x with 5 so c(x)= 17(5)-10 which equals 75$
4a: 4a wants you to find how many tickets you can buy for 130$. So first replace the y or c(x) with 130 x, which gives 130=17x-10. Now we find x, first add 10 to both sides to cancel the -10, 140=17x, then divide 17 from both sides which gives 8.235, so we can buy 8 tickets.
4b: It is discreet because it cannot be broken down into decimals or fractions, since you cannot have a halve of a ticket.

Can Defects A company that makes soda pop cans finds that the
probability of producing a can without a puncture is 0.96, the probability that
a can does not have a smashed edge is 0.93, and the probability that a can
does not have a puncture and does not have a smashed edge is 0.893.
(a) Are the events "selecting a can without a puncture" and "selecting a can
without a smashed edge" mutually exclusive? Explain.
(b) If a quality inspector randomly selects a can, find the probability that the
can does not have a puncture or does not have a smashed edge
Answers
Using probability concepts, it is found that:
a) Since [tex]P(A)P(B) \neq 0[/tex], the events are not mutually exclusive.
b) 0.997 = 99.7% probability that the can does not have a puncture or does not have a smashed edge.
Item a:
Two events, A and B, are mutually exclusive if:
[tex]P(A \cap B) = 0[/tex]
In this problem:
Event A: No puncture, thus, [tex]P(A) = 0.96[/tex].Event B: No smashed edges, thus [tex]P(B) = 0.93[/tex]The problem also states that the probability of neither is [tex]P(A \cap B) = 0.893[/tex].
Since [tex]P(A)P(B) \neq 0[/tex], the events are not mutually exclusive.
Item b:
Using Venn probabilities, the "or" probability is given by:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
With the given values:
[tex]P(A \cup B) = 0.96 + 0.93 - 0.893 = 0.997[/tex]
0.997 = 99.7% probability that the can does not have a puncture or does not have a smashed edge.

F(x) =?. Vertex is (2,-4) the other given point is (1,-2)
Answers
We could substitute these values into the vertex form of the quadratic function,
f(x) = a(x - h)^2 + k
where:
(h,k) is the vertex
The axis of symmetry is the vertical line x = 2
The value of “a” determines whether the graph opens up or down, and makes the parent function wider or narrower.
The value of “h” determines how far left or right the parent function is translated.
The value of “k” determines how far up or down the parent function is translated.
Now that we’ve established these definitions, we can substitute the given values into the vertex form:
f(x) = a(x - 2)^2 - 4
In order to determine the value of “a”, we must substitute the values of the other given point, (1, -2) into the equation:
f(x) = a(x - 2)^2 - 4
-2 = a(1 - 2)^2 - 4
-2 = a(-1)^2 - 4
-2 = a - 4
Add 4 to both sides to solve for “a”
-2 + 4 = a - 4 + 4
2 = a
Now that we have the value of a = 2, we can establish our quadratic function in vertex form:
f(x) = 2(x - 2)^2 - 4
I’m also including a screenshot of the graph of the function we came up with.

Which equation matches the graph of the greatest integer function given
below?
Answers
Answer:
D. y = [x] - 2
Explanation:
The Greatest Integer Function is denoted by y = [x].
For all real numbers, x, the greatest integer function returns the largest integer less than or equal to x. In essence, it rounds down a real number to the nearest lowest integer.
In the plot of y = [x], the plot starts from origin because y = [0] = 0.
But, in the question, all the lines are shifted 2 units downward, as it starts from (0, -2).
i.e for every values of x, y moves two units down
So our answer is y = [x] - 2.

Find the slope and y-intercept for this table.
Answers
Answer:
Slope is -5 and y-intercept is 90.
Step-by-step explanation:
Use the two values that you circles (4, 70) and (6, 60) .
slope (m) = the change in y-value/ (the change in the x-values).
m = (70 - 60)/(4 - 6) = 10/-2 = -5
The y-intercept is the value of "b" in the equation y = mx + b.
Using y = mx + b, substitute the value m and use point of your points (4, 70).
y = mx + b
70 = -5(4) + b Now solve for "b".
70 = -20 + b
+20 = +20
90 = b
