Answer:
Assuming you want to solve for x,
x = 2
Step-by-step explanation:
2x + y = 5
Solve for y
y = 5 - 2x
4x - 2y = 6
Solve for y
y = -3 + 2x
Since both these equations equal y, they must equal each other.
Make an equation for these to equal each other.
Then solve for x
5 - 2x = -3 + 2x
+ 2x + 2x Add
5 = - 3 + 4x
+ 3 +3 Add
8 = 4x
/4 /4 Divide
2 = x

Linear (=180)
Congruent (= each other)
Supplementary (= 180)
Complementary (= 90)
Answer:

Step-by-step explanation:
If f(x) =x/2 -2 and g(x) = 2x2 + x - 3, find (8 +g)(x),
O A. 2x2 - 2 +1
O B. x2 - 6
O C. 2x2 +2x+1
O D. 2x2 + x-5
2x-5
Answer: D) [tex]2x^{2} +\frac{3x}{2} -5[/tex]
Step-by-step explanation:
[tex]f(x)=\frac{x}{2} -2 \\g(x)= 2x^{2} +x-3\\\\\(f+g)(x)\\\[/tex]
[tex]\frac{x}{2} -2 +2x^{2} +x-3\\2x^{2} +\frac{x}{2} +x-5\\\\(f+g)(x)= 2x^{2} +\frac{3x}{2} -5[/tex]
The value of the expression (8 +g)(x) is 2x^2 + 3x/5 - 5, the correct option is D.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.
Linear function is a function whose graph is a straight line
We are given that;
f(x) =x/2 -2
g(x) = 2x2 + x - 3
Now,
To find (8 + g)(x), we need to add 8 to the function g(x).
g(x) = 2x^2 + x - 3
(8 + g)(x) = 8 + g(x) = 8 + (2x^2 + x - 3)
Simplifying the expression inside the parentheses:
= 2x^2 + x + 5
Therefore, the function (8 + g)(x) will be equal to 2x^2 + 3x/5 - 5.

8. Ace Cable TV offers two monthly plans. Plan A costs $55 a month plus $3 for each premium
channel the customer selects. Plan B costs $25 a month plus $8 for each premium channel
the customer selects. What number of channels will cause the cost of both plans to be the
same?
Answer:
8x:16
Step-by-step explanation:
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
55 + 3x = 25 + 8x
Where x is the number of premium channels
The number of channels at which the cost of both plans will be the same is 6.
What is an equation?
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
We have,
Number of premium channels = x
Plan A:
Monthly cost = $55
Cost of each premium = $3
Total cost = 55 + 3x _____(1)
Plan B:
Monthly cost = $25
Cost of each premium = $8
Total cost = 25 + 8x ______(2)
From (1) and (2).
The number of channels when the cost of both plans will be same.
55 + 3x = 25 + 8x
Subtract 25 on both sides.
55 - 25 + 3x = 8x
30 + 3x = 8x
Subtract 3x on both sides.
30 = 8x - 3x
30 = 5x
Divide both sides by 5.
x = 6
Thus,
The number of channels at which the cost of both plans will be the same is 6.

Step-by-step explanation:
For figure ABCDEF shown here, identify the image after a clockwise rotation of 240°, or counterclockwise
rotation of 120°. The naming always begins at the top of the figure and proceeds clockwise. For example,
a reflection across AD has an image of AFEDCB. Drag and drop each letter into the correct box to identify
the image after a clockwise rotation of 240°, or a counterclockwise rotation of 120°.
Answer:
Step-by-step explanation:
Since, ABCDEF is a regular hexagon,
Measure of central angle of a regular polygon = [tex]\frac{360}{n}[/tex]
where n = number of sides of the polygon
Measure of central angle of regular hexagon = [tex]\frac{360}{6}[/tex] = 60°
That means when we rotate a regular hexagon by an angle in the multiple of 60°, hexagon overlaps itself.
Therefore, by the rotation of 240° clockwise, point C will replace the position of point A.
Image of hexagon ABCDEF will become CDEFAB.
Similarly, after rotation by 120° counterclockwise about the center image hexagon will be EDCBAF.

Compute the standard deviation of job satisfaction scores for both probability distributions (to 2 decimals). Executives Middle managers e. What comparison can you make about the job satisfaction of senior executives and middle managers? - Select your answer -
Answer:
Kindly see explanation
Step-by-step explanation:
Given the data:
JOB satisfaction (x) : 1, 2, 3, 4, 5
IS Senior ; p(x) : 0.05, 0.09, 0.03, 0.42, 0.41
IS Middle ; p(x) : 0.04, 0.10, 0.12, 0.46, 0.28
Expected value of job satisfaction for senior executives :
E(x) = Σp(x) * x = [(1*0.05) + (2*0.09) + (3*0.03) + (4*0.42) + (5*0.41)]
= 4.05
B) Σp(x) * x = [(1*0.04) + (2*0.10) + (3*0.12) + (4*0.46) + (5*0.28)]
= 3.84
C.) Job variance for executives:
Σ(x - E(x))² * p(x) :
((1 - 4.05)^2 * 0.05) + ((2 - 4.05)^2 * 0.09) + ((3 - 4.05)^2 * 0.03) + ((4 - 4.05)^2 * 0.42) + ((5 - 4.05)^2 * 0.41)
= 1.2475 = 1.25 ( using calculator)
job variance for middle managers :
Σ(x - E(x))² * p(x) :
((1 - 3.84)^2 * 0.04) + ((2 - 3.84)^2 * 0.10) + ((3 - 3.84)^2 * 0.12) + ((4 - 3.84)^2 * 0.46) + ((5 - 3.84)^2 * 0.28)
= 1.1344 = 1.13 (using calculator)
Standard deviation(sd) for (senior managers) :
sd = √variance
sd = √1.25 = 1.118 = 1.12
Standard deviation(sd) for (middle managers) :
sd = √variance
sd = √1.13 = 1.063 = 1.06
The expected value (mean) for senior executives (4.05) is slightly higher Than obtained for middle managers (3.84). Similarly the measure of Variation in job satisfaction ; standard deviation and variance is also higher for senior managers than in middle managers.
Mariah has 714 postcards to put in an album each page of the album holds 10 postcards how many pages does Mariah need for her postcards
Answer:
72 pages
Step-by-step explanation:
If each page holds 10 cards, then we find the number of pages needed, we just need to divide the number of postcards by how many fit on each page.
So 714/10=71.4, or 71 r4
Because we do not have a whole number, we need to add another page so the extra 4 postcards have a page.
Therefore Mariah need 72 pages to hold her 714 postcards.

Which does NOT show a reasonable estimate for 673 × 18?
A. 14,000
B. 13,500
C. 13,000
D. 10,000
Answer:
A. 14,000
Step-by-step explanation:
because 673 rounded would equal 700
and 18 rounded would be 20
so 700x20 would be 14,000
hopefully you understand
and i hope you have a good day :)
14,000 will not be the reasonable estimate for 673 × 18. The correct option is A.
What is multiplication?Multiplication is the process of determining the product of two or more numbers in mathematics. A product, or an expression that specifies factors to be multiplied, is what happens when you multiply two numbers in mathematics.
The product of the numbers 673 and 18 will be:-
673 x 18 = 12114
673 rounded would equal 700 and 18 rounded would be 20 and the product of 700 and 20 will be:-
700x20 = 14,000
Therefore, 14,000 will not be the reasonable estimate for 673 × 18. The correct option is A.
