Identify a transformation of the function f(x) = x by observing the equation of the function g(x) = m x, with m > 1.
The transformation from f(x) to g(x) is a vertical stretch by a factor of m
How to determine the transformation?The functions are given as:
f(x) = x
g(x) = mx
Substitute f(x) = x in g(x) = mx
g(x) = mf(x)
From the question, we understand that:

on a piece of paper graph y>-x+2 then determine which answer choice matches the graph you drew
The answer that matches the information in the graph is zero x = -2.
How to illustrate the graph?The zeros of a function are the point on which graph intersects the x axis or we can say the value of x when y = 0.
Substitute y = 0 in the provided equation.
0 = x + 2
x = -2
The coordinate is (-2,0). Also the zero of the graph is at x = -2 because it follows the definition of zeros.
Now substitute x = 0 in the provided equation.
y = 0 + 2
y = 2
The coordinate is (0,2).
Hence, the answer that matches the information is zero x = -2.

Given that a function, h, has a domain of -3 ≤ x ≤ 11 and a range of 1 ≤ h(x) ≤ 25 and that h(8) = 19 and h(-2) = 2.
1.) h(8) = 21
Since the value of h(8) is 19. This can not be the correct option.
2.) h(-3) = -1
Since the range is from 1 to 25. Therefore, this is not the correct option.
3.) h(13) = 18
Since the domain is from -3 to 11. Therefore, this is not the correct option.
4.) h(2) = 16

The difference in the height of the two rectangles is 7 feet.
One rectangle has a height of 6.2 feet and another has a height of y feet.
What is the value of y?
Answer:
y = 13.2ft
Step-by-step explanation:
This is a bit of trial and error.
We know that the height of one rectangle is 6.2ft, which means we cannot subtract 7 from 6.2 to find the height of the other rectangle as it will give us a negative value and it will not make sense.
Therefore the height of the other rectangle has to be 7ft higher.
y = 6.2 + 7 = 13.2ft

compute 1 + 2 + 3 +....+ 99 + 100 + 99 + 98 +...+ 3 + 2 + 1
Answer:
10000
Step-by-step explanation:
When computing a consecutive sum of integers with a difference of 1.
Use gauss's formula of (n/2)(first number + last number).
with n being the # of integers.
Since it is ascending and descending, it can be broken down into 2 sequences:
1 + 2 + 3 + ... + 99 and 1 + 2 + 3 + ... + 100.
Once each is calculated, add them up to find the value.
So:
1 + 2 + 3 + ... + 99 = (99/2)(100) = 4950.
1 + 2 + 3 + ... + 100 = (100/2)(101) = 5050.
4950 + 5050 = 10000

928; 44°
Answer:
Magnitude and Direction is 928 and 44
Step-by-step explanation:
For a Vector w = (x)i+(y)j
The Magnitude of w [tex]=\sqrt{x^{2} +y^{2} }[/tex]
and the Direction of w [tex]=tan^{-1}(\frac{y}{x} )[/tex]
So for our Question , w = - 168i - 160j
Then -4w = -4 (- 168i - 160j) = (-4*-168)i +(-4*-160)j = 672i + 640j
Then the Magnitude of -4w = [tex]\sqrt{672^{2} +640^{2} } =928[/tex]

A quadrilateral is shown. One pair of opposite sides have lengths of 10 inches and (x + 2) inches. The other pair of opposite sides have lengths (x + 5) inches and (2 x minus 3) inches. Based on the measures shown, could the figure be a parallelogram? Yes, one pair of opposite sides could measure 10 in., and the other pair could measure 13 in. Yes, one pair of opposite sides could measure 10 in., and the other pair could measure 8 in. No, there are three different values for x when each expression is set equal to 10. No, the value of x that makes one pair of sides congruent does not make the other pair of sides congruent.
Answer:
1st option
Step-by-step explanation:
since one pair of opposite sides 10 in , then
x + 2 = 10 ( subtract 2 from both sides )
x = 8
Then
x + 5 = 8 + 5 = 13 in
2x - 5 = 2(8) - 5 = 16 - 5 = 13 in
The opposite sides of a parallelogram are parallel and congruent.
So the quadrilateral could be a parallelogram
Answer: A) Yes, one pair of opposite sides could measure
10 in., and the other pair could measure 13 in.

Answer:
The second graph
Step-by-step explanation:
Well you're given the equation in slope-intercept form, which looks like: y=mx+b, where m is the slope, and b is the y-intercept. This is because the y-intercept is when x=0, so mx will becomes 0, thus leaving b alone, and making it the y-intercept. m is the slope because as x increases by 1, the y-value goes up by m, so the "rise" is m and the "run" is 1. The definition of the slope is rise/run so the slope would be m/1 or just m.
So let's analyze the equation: y=25x+40. the slope will be 25, and the y-intercept will be 40 (this is important for easily filtering very obviously wrong answer). So the linear equation will intersect the y-axis at (0, 40). Only one of the graphs intersects the y-axis at (0, 40) which is the second graph.

We can do the inverse, where division basically becomes multiplication. You just flip the denominator and numerator (lower and upper part of the division sign).
[tex]\frac{2}{3} *-\frac{5}{2}[/tex]
The negative stays even when you inverse it. Make sure on future problems you inverse whats being divided, which in this case was -2/5.
We can now multiply across and get:
[tex]- \frac{10}{6}[/tex] as 2•5=10, 3•-2=-6. Therefore -10/6.
Which can be simplified into [tex]-1 \frac{2}{3}[/tex]. This is because 10 goes into 6 once leaving 4. That makes it -1 4/6, but 4/6 can be reduced by a common factor, 2. So just divide 4 and 6 by 2, which is 2/3. So thats why it is -1 2/3.

Ms. wilkinson's fifth-grade class is running a canned food drive. the students filled two boxes of food. there are thirty 300-gram cans of soup in one box. there are eighteen 400-gram cans of vegetables in the other box. how many kilograms of food did the students collect in all?
Answer:
16.2 kilograms
Step-by-step explanation:
30 300-gram cans = 9000 grams of soup
18 400-gram cans = 7200 grams of vegetables
9000 + 7200 = 16200 grams
1000 grams = 1 kilogram
16200 / 1000 = 16.2 kilograms
The total amount of food students collect in kilograms will be equal to 16.2 kilograms food.
What is algebra ?
Algebra is a branch of mathematics that deals with various symbols and the arithmetic operations such as division , multiplication , etc.
The number of cans of soup in one box = 30 cans
And each can has 300 grams of soup.
So , the total amount of soup in one box is :
= 30 × 300
= 9000 grams of soup
Now , in the other box there are 18 cans of vegetables and each can has 400 grams of vegetable.
So , the total amount of vegetable in the other box is :
= 18 × 400
= 7200 grams
Total food students collect is :
= 9000 grams soup + 7200 grams vegetables
= 16200 grams food
We know that :
1000 grams = 1 kilogram
So , converting grams into kilograms we get :
16200 / 1000 = 16.2 kilograms food
Therefore , the total amount of food students collect in kilograms will be equal to 16.2 kilograms food.

What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is the y-intercept.
The parallel line passes through the points (-4,-2) and (-3,-3). Therefore, the slope of the line is,
Slope = (-2 + 3) / (-4 + 3) = 1/-1 = -1
The equation of the parallel line that is passing through point P is,
y = mx + c

Step-by-step explanation:
In the question it is given that a cell phone company offers two plans for minutes.

Plan B: $50 per month with free unlimited texts.
It is required to find that how many texts would be needed to send per month for plan B to save money. be needed to send per month for plan B to save money.
Step 1 of 5
In Plan A $20 per month and $1 for every one hundred texts are costed so the cost of Plan A is given by following equation,
[tex]$A=20 y+\frac{x}{100}$[/tex]
In Plan B $50 per month with free unlimited texts are costed so the cost of Plan B is given by following equation,
[tex]$$B=50 y$$[/tex]
Step 2 of 5
Now comparing the obtained equations [tex]$A=20 y+\frac{x}{100}$[/tex]
and B=50y.
[tex]$20 y+\frac{x}{100}=50 y$$[/tex]
Step 3 of 5
Subtract 20y from both the sides of the obtained equation [tex]$20 y+\frac{x}{100}=50 y$[/tex] and simplify using subtraction properties.
[tex]$$\begin{aligned}&20 y+\frac{x}{100}-20 y=50 y-20 y \\&\frac{x}{100}=30 y\end{aligned}$$[/tex]
Step 4 of 5
Multiply both the sides of the obtained equation [tex]$\frac{x}{100}=30 y$[/tex] by 100 and simplify using multiplication properties.
[tex]$$\begin{aligned}&\frac{x}{100} \cdot 100=30 y .100 \\&x=3000 y\end{aligned}$$[/tex]

Divide both the sides of the obtained equation x=3000y by y and simplify using division properties.
[tex]$$\begin{aligned}&\frac{x}{y}=\frac{3000 y}{y} \\&\frac{x}{y}=3000\end{aligned}$$[/tex]
As [tex]$\frac{x}{y}$[/tex] expresses the average texts sent per month by cell phone user. So, for plan B to save money cell phone user need to send 3000 texts per month.
