Answer:
x=-5
Step-by-step explanation:
any line parallel to x=a is x=b
line parallel to x=-2 is x=-5
The equation of the line is x = -5.
What is the Linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
The line x = -2 is a vertical line passing through the point (-2, y) for all y. Since we want a line parallel to this line, it must also be a vertical line.
Therefore, the equation of the line that is parallel to x = -2 and passes through the point (-5, 4) is simply x = -5.
So the answer is x = -5.

===============================================================
Explanation:
Unfortunately your teacher is a bit vague here, but I'm assuming that the roots listed in the table are the only roots (and there aren't any other roots possible). If other roots were possible, then we'd have infinitely many possible answers and it would greatly muddy up the problem.
So we'll just stick to the basic assumption that the only roots are: -2, 0, and 2.
With that key assumption in mind, let's look at the answer choices to see which are true and which are false.
A) False. This is because we see that f(x) = -15 when x = -3. Note how x = -3 is in the interval [tex](-\infty, 3)[/tex]. In other words, this is a counter example showing that f(x) > 0 is not the case when x is between -infinity and 3.B) True. Over the interval [tex]0 \le x \le 2[/tex], we have f(x) either equal to 0 or a negative value. For the interval 0 < x < 2, we would have f(x) < 0.C) False. The table shows that f(0) = 0 which means we aren't making f(x) < 0 to be the case. D) True. The table shows that if -2 < x < 0, then f(x) is positive. An example of this is f(-1) = 3 which is positive. The f(x) values in this region are above the x axis. E) True. We have f(x) either equal to 0 or something larger when [tex]x \ge 2[/tex] which translates over to the interval notation [tex][2, \infty)[/tex]From that list above, we see that choices B, D and E are true.

Rohann recently finished some renovations to his house. 20 square meters of carpeting cost $875 while 17 square meters of hardwood flooring cost $750. Which flooring is more expensive per square meter?
Answer: Hardwood flooring
Step-by-step explanation:
Given
Rohann renovation of Carpentering cost $875 for [tex]20\ m^2[/tex]
For hardwood flooring [tex]17\ m^2[/tex] cost $750
So, cost per square meter for different floors are
[tex]\Rightarrow \text{Carpentering}=\dfrac{875}{20}\\\\\Rightarrow \text{Carpentering}=\$43.75/m^2[/tex]
[tex]\Rightarrow \text{Hardwood}=\dfrac{750}{17}\\\\\Rightarrow \text{Hardwood}=\$44.11/m^2[/tex]
Thus, the cost of the Hardwood flooring is more expensive.

Find the volume of a pyramid with a square base, where the area of the base is 12.5 ft ^2 12.5 ft
2
and the height of the pyramid is 16 ft. Round your answer to the nearest tenth of a cubic foot.
Answer:
833.3 ft^3
Step-by-step explanation:
The formula for the volume of a pyramid is:
V = (lwh)/3
V = volume
l = length of base
w = width of base
h = height of pyramid
Now we just correspond the values with the variables:
l = 12.5
w = 12.5
h = 16
And plug these values into the formula:
((12.5)(12.5)(16))/3
((156.25)(16))/3
2500/3
833.3 ft^3
Hope this helps (●'◡'●)
The solution is : the volume of a pyramid with a square base is 833.3 ft^3.
What is volume?In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.
here, we have,
we know that,
The formula for the volume of a pyramid is:
V = (lwh)/3
V = volume
l = length of base
w = width of base
h = height of pyramid
Now we just correspond the values with the variables:
l = 12.5
w = 12.5
h = 16
And plug these values into the formula:
=((12.5)(12.5)(16))/3
=((156.25)(16))/3
=2500/3
=833.3 ft^3
Hence, The solution is : the volume of a pyramid with a square base is 833.3 ft^3.

Help urgent In a class of 35 students 15 of them have cats 16 have dogs 3 hangs none how many probability does have both
Answer:
9/25
Step-by-step explanation:
Number of student who has cat , dog = 25 - 3 = 22
Number of students who has cat and dogs = (15 + 16) - 22
= 31 - 22 = 9
Number of students who has only cats = 15 - 9 = 6
Number of students who has only dogs = 16 - 9 = 7
P(Cat & dog) = 9/25
8. Anneke is swimming the 500-meter freestyle, which consists of swimming the length of a pool 20 times. If Anneke averages 26.4 seconds per length of pool, write an equation that could be used to determine the number of meters (m) Anneke has left in the event after swimming for s seconds.
Answer:
Anneke will swim 20 lengths in the 500-meter event,
which means each length of the pool is = 500/20
= 25m
also since Anneke can swim one length in 26.4 seconds on average
hence her average speed is = 25/26.4 m/s
hence after a seconds,
the distance traveled = 25s/26.4 meter
thus, the remaining distance Anneke need to travel is:
m = 500 - (25s/26.4)

A polynomial p has zeros when x = -2, x = 1/3, and x =3.
What could be the equation of p? Choose 1 answer:
a. p(x) = (x + 2)(x + 3)(3x + 1)
b. p(x) = (x + 2)(x + 3) (3x - 1)
C. p(x) = (x + 2)(x - 3)(3x - 1)
D. p(x) = (x - 2)(x + )(3x + 1)
Answer:
p(x) = ( x +2) (3x - 1) ( x-3)
Step-by-step explanation:
We know the equation for a polynomial with given zeros is
f(x) = a(x-b1) (x-b2)...... where b are the zeros and a is a constant
Since the zeros are x = -2, x = 1/3, and x =3.
p(x) = a( x - -2) (x - 1/3) ( x-3)
p(x) = a( x +2) (x - 1/3) ( x-3)
We can pick the value of a since we are not given a point on the function. Pick a=3
p(x) = 3( x +2) (x - 1/3) ( x-3)
Rewriting the second term
p(x) = ( x +2) (3x - 1) ( x-3)

Angle is a defined term.
What is defined term?
In geometry defined term, that have a formal definition and can be defined using other geometrical terms is called a defined term.
According to the given question
We have some terms
Angle, Line, Point and Plane
Now,
In geometry, we can define an angle using undefined term of a line. That is we define an angle as the corners that are created when two non-parallel lines intersect each other, so angle is a defined term.
In Geometry, we define a point as a location or size .
A line is defined as something that extends infinitely in either direction but has no width and is one dimensional.
While plane extends infinitely in two dimensions.
Hence, line, point and plane are undefined terms.

Without graphing, explain how you know the equation
y = - 1/2x^2 - 7 will be compressed
(compared to the parent function of y=x^2).
Answer:
" because the coefficient of the x^2 term is less than 1 (between -1 and + 1)
y = x^2 looks like a big U with the vertex (bottom) "kissing" the origin (0,0)
if you add 1 to the equation y = x^2 + 1 it shifts UP one
if you subtract 3 y = x^2 -3 it shifts down three ....
if you change it to look like this y = (x+4)^2 it shifts (slides) to the LEFT 4 units..
note that this slide is opposite to the sign + 4 left slide , - 4 right slide...
NOW YOUR QUESTION !!!! if the coefficient is > 1
y = 99 x^2 then the graph gets "skinny" goes up faster...
if it is less than one (between -1 past 0 to +1 ) then it flattens out
Bottom line here your coefficient is a "-1/2"
so YOUR GRAPH IS A ∩ (goes downward) and is FLATTER than the normal ∪
