What is the equation of the line that passes through the point (-1,4)and has a slope of -5?
Answer:
y = -5x - 1
Step-by-step explanation:
NOTE: This equation is in slope-intercept form. The equation in point-slope form is y - 4= -5(x + 1).
The formula for calculating slope-intercept form is y = mx + b.
Substitute the slope and the x and y intercepts for the equation: 4 = -5(-1) + b
4 = 5 + b
Subtract 5 from both sides.
So, -1 = b.
Now substitute the slope for m and -1 for b.
y = -5x + -1
= y = -5x - 1
Write a rule to describe the transformation.
Answer:
1.) Reflect across x-axis
2.) Reflect across y-axis
3.) Move to the right by one unit
Step-by-step explanation:
The reflection rule is ''about the origin''.
Used the concept of reflection that states,
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the origin, the x-coordinate and y-coordinate do not change places and are negated.
Given that,
Two figures VWGY and V'W'G'Y' is shown in the figure.
From the figure,
V = (0, - 2)
W = (- 1, 0)
G = (2, 0)
Y = (5, - 4)
V' = ((0, 2)
W' = ( 1, 0)
G' = (- 2, 0)
Y' = (- 5, 4)
Hence the coordinate satisfies the rule (x, y) → ( - x, - y).
So, the reflection rule is about the origin.

A university student spends his summer months in his home town, where he works for a local microbrewery during the evening hours. In the late morning, he attends the local community college, where he takes summer courses that he knows will transfer back to his school. Although he finds the courses just as challenging as at his regular university, he does not worry about his summer grades affecting his 3.2 (out of 4.0) grade point average, because his university only accepts the transfer credits. As long as he receives C grades or better, he maintains his current grade point average. Which theory suggests that the student will work only as hard as necessary to earn a C grade
Answer:
Expectancy theory
Step-by-step explanation:
We are told that as long as he receives C grades or better, he maintains his current grade point average.
This means that;
There is a large tendency for him to work just hard enough to earn a c grade.
This depicts vrooms expectancy theory of motivation which is defined as a theory whereby a person or persons will act in a particular way just for the sake of what they will gain from exhibiting that particular selected behavior instead of others.

simplify sqrt24w^14
Answer:
2×sqrt(6)×w⁷
Step-by-step explanation:
what I can read here, you need to simplify
sqrt(24×w¹⁴)
= sqrt(24)×sqrt(w¹⁴) = sqrt(4×6)×sqrt(w¹⁴) =
= 2×sqrt(6)×sqrt(w¹⁴)
and taking the square root of something with exponent simply means dividing that exponent by 2
so,
2×sqrt(6)×w⁷
Consider the equation y\:=\:-x^2\:-\:7x\:+\:12. Determine whether the function has a maximum or a minimum value. State the maximum or minimum value. What are the domain and range of the function?
Answer:
Step-by-step explanation:
To answer this we need only know that negative parabolas are upside down, so by definition, it has a max point at the vertex. To find the vertex (h, k), the easy way to do this is to fill in the following expressions for h and k and solve:
[tex]h=\frac{-b}{2a}[/tex] and [tex]k=c-\frac{b^2}{4a}[/tex] (These are derived from the quadratic formula). Filling in knowing our a = -1, b = -7, c = 12:
[tex]h=\frac{-(-7)}{2(-1)}=\frac{7}{-2}=-\frac{7}{2}[/tex] and
[tex]k=12-\frac{(-7)^2}{4(-1)}=12-(\frac{49}{-4})=12+\frac{49}{4}=\frac{97}{4}[/tex] so the vertex (aka max height occurs at [tex](-\frac{7}{2},\frac{97}{4})[/tex]. Depending upon what is meant by stating the max value, we may only need to state the k value (which is the same as the y coordinate, which is an up or down thing as opposed to the x value which is a side to side thing). The domain is all real numbers, as is the case for all x-squared parabolas, and the range is
R = {y | y ≤ 97/4}

in ten minutes he traveled 8 miles Write the equation for the relationship between x and y.
Answer:
Step-by-step explanation:
The trick here is to make sure that the units are standard units, like miles / hour.
10 minutes = 10 / 60 hours.
k = 1/6 of an hour
y = k x
k = y/x
k = 8 miles / 1/6 of an hour
k = 8 * 6 // 1/6 * 6
k = 48 miles / hr
y = k x
y = 48 * x

10a^9-33a^3
Help plzz
Answer and Step-by-step explanation:
I think you have to factor the expression.
You can take out [tex]a^3[/tex], to get the expression:
[tex]a^3(10a^6-33)[/tex] <- Answer.
When multiplying values with exponents, the exponents add together, and when dividing values with exponents, the exponents subtract from each other.
In this situation, we divided [tex]a^3[/tex] from the expression, with the expressions having exponents of 9 and 3. We subtract 3 from 9 and 3 from 3, resulting in the 6 and 0 (not shown because it isn't needed to show).

Divide by -5
(x+11)/-5 = -5y/-5
-1/5(x+11) = y
f^-1(x) = -1/5(x+11)

A cone's circular base has a diameter of 8 feet. The volume of the cone is 279 cubic feet. What is the approximate height of the cone?
Solution :Given Data :
Diameter = 8 ft
Volume of Cone = 279 ft³
Formula for Cone
[tex] \: \: \: \: \: \: \: \: \: \: \: \ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \star \: \: \green{\underline{ \green{ \overline{ \blue{\boxed{ \frak{ \pink{Volume \: of \:Cone = πr² \frac{h}{3} }}}}}}}}[/tex]
____________________________________
As we know radius is diameter/2
Radius = 8/2 = 4 ft
Now, putting the values in the formula we get
[tex] \mapsto \frak{Volume = \frac{22}{7} \times {4}^{2} \times \frac{h}{3} }[/tex]
[tex]\mapsto \frak{Volume = \frac{22}{7} \times 16 \times \frac{h}{3} }[/tex]
[tex] \mapsto \frak{Volume = \frac{352}{21} h }[/tex]
Now, putting the value of volume which is 279 ft we get
[tex] \mapsto \frak{279 = \frac{352}{21}h }[/tex]
[tex] \mapsto \frak{h = 279 \times \frac{21}{352} }[/tex]
[tex]\mapsto \frak{h = 16.64 \: ft }[/tex]
After approximating we will get the value as 16.65 ft
Hence, the correct answer is the first option i.e 16.65 ft

3. The vertices of trapezoid WXYZ are W(-2, 4), X(-3, 2), Y(-3, 1), and Z(-2, 1).
Which figure shows the image of trapezoid WXYZ for a glide reflection where the translation is (x, y) - (x + 2, y) and the line of
reflection is y = 0?
Step-by-step explanation:
I don't know, if I see the full picture. I see only 2 diagrams.
since the line of reflection is y=0 (= the x-axis), it can be only the upper diagram.
and something might be wrong with your translation description.
but as I said, given these two choices, due to the line of reflection, it can be only the upper diagram.
Find the value of x that makes lines u and v parallel. 11x-2 is the "larger" looking angle on the left.
Answer: 12
11x - 2 = 130
11x = 130 + 2
11x = 132
x = 132/11
x = 12
Now with value x the angle will be 130 and using converse of corresponding angles theorem line v and u will be parallel

PÕQ = 40°? [WAEC] A pie chart is divided into four sectors as shown in Fig. 12.46. Each sector represents a percentage of the whole. The two larger sectors are equal and each represents x%. What is the angle subtended by one of those (WAEC] larger sectors?
Answer:
126°
Step-by-step explanation:
the total max percent can be 100%
OR
The total value of the pie is 100%
that means all sectors must add upto 100
=> x + x + 21 + 9 = 100
=> 2x + 30 = 100
=> 2x = 70
=> x = 35
therefore, the two large sectors which are both equal to x each represents 35% of the whole.
Angle subtended by one of those large sectors :-
[tex] \theta = \frac{component \: part}{total} \times 360[/tex]
[tex] = \frac{35}{100} \times 360 \\ = 126[/tex]
therfore, the central angle of the big sector is 126°
c) Next, you will make a scatterplot. Name a point that will be on your scatterplot and describe what it

A scatter plot is defined as the mathematical representation of two variables of a given data set. It shows the relationship between the two variables and is plotted graphically.
In the scatter plot attached below, in the x-axis, the number if ice creams are plotted. And the y-axis shows the sales revenue generated by selling ice creams.
Thus the point (12, 190) shows that by selling 12 ice creams, the company generated a sale of $190.
