QUESTION 1.
Choice C is correct. Subtracting 6 from each side of 5x + 6 = 10 yields 5x = 4.
Dividing both sides of 5x = 4 by 5 yields x =
_4
5
. Te value of x can now be
substituted into the expression 10x + 3, giving 10 ( _4
5 ) + 3 = 11.
Alternatively, the expression 10x + 3 can be rewritten as 2(5x + 6) − 9, and
10 can be substituted for 5x + 6, giving 2(10) − 9 = 11.
Choices A, B, and D are incorrect. Each of these choices leads to 5x + 6 ≠ 10,
contradicting the given equation, 5x + 6 = 10. For example, choice A is
incorrect because if the value of 10x + 3 were 4, then it would follow that
x = 0.1, and the value of 5x + 6 would be 6.5, not 10.
QUESTION 2.
Choice B is correct. Multiplying each side of x + y = 0 by 2 gives 2x + 2y = 0.
Ten, adding the corresponding sides of 2x + 2y = 0 and 3x − 2y = 10 gives
5x = 10. Dividing each side of 5x = 10 by 5 gives x = 2. Finally, substituting
2 for x in x + y = 0 gives 2 + y = 0, or y = −2. Terefore, the solution to the
given system of equations is (2, −2).
Alternatively, the equation x + y = 0 can be rewritten as x = −y, and substituting x for −y in 3x − 2y = 10 gives 5x = 10, or x = 2. Te value of y can then
be found in the same way as before.
Choices A, C, and D are incorrect because when the given values of x and
y are substituted into x + y = 0 and 3x − 2y = 10, either one or both of the
equations are not true. Tese answers may result from sign errors or other
computational errors.
QUESTION 3.
Choice A is correct. Te price of the job, in dollars, is calculated using
the expression 60 + 12nh, where 60 is a fxed price and 12nh depends on the
number of landscapers, n, working the job and the number of hours, h, the job
takes those n landscapers. Since nh is the total number of hours of work done
when n landscapers work h hours, the cost of the job increases by $12 for each
hour a landscaper works. Terefore, of the choices given, the best interpretation
of the number 12 is that the company charges $12 per hour for each landscaper.
Choice B is incorrect because the number of landscapers that will work each
job is represented by n in the equation, not by the number 12. Choice C is
incorrect because the price of the job increases by 12n dollars each hour,
which will not be equal to 12 dollars unless n = 1. Choice D is incorrect
because the total number of hours each landscaper works is equal to h. Te
number of hours each landscaper works in a day is not provided.
QUESTION 4.
Choice A is correct. If a polynomial expression is in the form (x)2
+ 2(x)(y) +
(y)2
, then it is equivalent to (x + y)2

b2

)2
+
2(3a2
)(2b2
) + (2b2
)2
, it can be rewritten as (3a2

)2
.
Choice B is incorrect. Te expression (3a + 2b)4
is equivalent to the product
(3a + 2b)(3a + 2b)(3a + 2b)(3a + 2b). Tis product will contain the term
4(3a)3
(2b) = 216a3
b. However, the given polynomial, 9a4
+ 12a2
b2
+ 4b4
,
does not contain the term 216a3
b. Terefore, 9a4

Choice C is incorrect. Te expression (9a2

Find an

are
Answers
Answer:
[tex]y=-2x-4[/tex]
Step-by-step explanation:
Perpendicular Bisector
The bisector of a segment defined by points (x1,y1) and (x2,y2) must pass by the midpoint of the segment.
The midpoint (xm,ym) is calculated as follows:
[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]
[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]
The endpoints of the segment are (-3,-8) and (5,-4), thus the midpoint M is:
[tex]\displaystyle x_m=\frac{-3+5}{2}=1[/tex]
[tex]\displaystyle y_m=\frac{-8-4}{2}=-6[/tex]
Midpoint: M(1,-6)
Let's find the slope of the given segment. The slope can be calculated with the formula:
[tex]\displaystyle m_1=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\displaystyle m_1=\frac{-4+8}{5+3}=\frac{1}{2}[/tex]
If the bisector is also perpendicular, its slope m2 and the slope of the segment m1 must comply:
[tex]m_1.m_2=-1[/tex]
Solving for m2:
[tex]\displaystyle m_2=-\frac{1}{m_1}=-\frac{1}{\frac{1}{2}}=-2[/tex]
Once we have the slope -2 and the point through which our line must pass (1,-6), we compute the equation in its point-slope form:
[tex]y-y_o=m(x-x_o)[/tex]
[tex]y-(-6)=-2(x-1)[/tex]
Operating
[tex]y+6=-2(x-1)[/tex]
[tex]y+6=-2x+2[/tex]
Rearranging

Answers
Answer:
3 + x
Step-by-step explanation:
Sum means to add, so you would just add 3 and x (since they haven't given an actual number and only a variable).
The sum of the number 3 and the variable x will be (x + 3).
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
In the linear expression, the degree of the variable is one.
The sum of 3 and a number x.
Then the expression will be
⇒ 3 + x
The number 3 is a constant number and the term x is a variable.
The expression (x + 3) is a linear expression because the degree of the expression is one.
The number of the variable is one, then the expression is linear expression of one variable.
Thus, the sum of the number 3 and the variable x will be (x + 3).

We want to factor in the following expression:
16x⁴-(y-1)²
We can factor the expression as (U+V)(U-V) where U and V are either constant integers or single-variable expressions.
1) What are U and V?
2)Factor the expression.
We have an expression:
= 16x⁴-(y-1)²
or
= (4x²)²-(y-1)²
Using the identity:
a² - b² = (a + b)(a- b)
(4x²)²-(y-1)² = (4x² + (y-1))(4x² + (y+1))
The value of U = 4x²
V = (y-1)
The factor of the expression is:
(4x² + (y-1)) and (4x² + (y+1))
Thus, the value of U and V are 4x² and (y-1) respectively and the factor of the expression is (4x² + (y-1)) and (4x² + (y+1))

A swimmer is looking for a species of fish along the coast line. She dives 12 feet below the surface of the ocean. Then she dives down 9 more feet. She swims back up 10 feet and down another 6 feet before she finds the species of fish she is looking for. What was the depth at which the swimmer finds the fish?
Answers
Answer:
17 feet
Step-by-step explanation:
Given
Downward Movements: 12 feet; 9 feet; 6 feet
Upward Movement: 10 feet
Required
Determine the position at which the swimmer got the fish
First, we need to add up the downward movements;
[tex]Downward = 12ft + 9ft + 6ft[/tex]
[tex]Downward = 27ft[/tex]
Then subtract the upward movement
[tex]Position = Downward - Upward[/tex]
[tex]Position = 27ft - 10ft[/tex]

The bright line spectrum of Neon contains a line with the wavelength of 700 nm. What is the
frequency of this light and what color is it?
Answers
Answer:
1) The frequency of the light is approximately 4.283 × 10¹⁴ Hz
2) The color of the light is red
Step-by-step explanation:
1) The given parameter;
The wavelength of the line contained in the Neon spectrum, λ = 700 nm = 0.0000007 m = 7.0 × 10⁻⁷ m
The speed of light, v = 299,792,000 m/s
v = f × λ
The frequency, f of the light = v/λ = 299,792,000/(7.0 × 10⁻⁷) ≈ 4.283 × 10¹⁴ Hz
The frequency of the light ≈ 4.283 × 10¹⁴ Hz
2) Given that light with wavelength between 620 - 750 nm constitute red light, we have that the given light with a wavelength of 700 nm is a red light source.

The parking spaces in a city lot were created by painting rows of parallel line segments, then painting a line that cuts through each of the parallel segments. A sketch of two parking spaces is shown below. 2 diagonal parallel lines are cut by a horizontal transversal. Where the first parallel line intersects the transversal, the top right angle is angle 1. Where the second parallel line intersects the transversal, the top left angle is angle 2. If m∠2 = 115°, what is m∠1?
Answers
Answer:
65°
Step-by-step explanation:
The consecutive interior angles theorem states that if two parallel lines are cut by a transversal line then the resulting pair of consecutive angles formed are supplementary (that is they add up to 180°).
Given that the painting rows are parallel to each other and a painted line (transversal) cut the parallel lines forming consecutive interior angles m∠1 and m∠2. Therefore:
m∠1 + m∠2 = 180°
m∠1 + 115 = 180
m∠1 = 180 - 115
m∠1 = 65°
