Free cookies Just answer this question! Elena solves the equation x^2=7x by dividing both sides by x to get 7. She says
the solution is 7. Lin solves the equation x^2=7 by rewriting the equation to get
x^2-7=0. When she graphs the equation x^2-7=0, the x-intercepts are (0,0) and
(7,0). She says the solutions are 0 and 7. Why should Elena not divide by x?
x could be equal to zero, and we can't divide by zero, so we shouldn't divide by x.
Why should Elena not divide by x?
Here we have the quadratic equation:
[tex]x^2 = 7x[/tex]
Notice that we don't know the value of x, so technically, x could be equal to zero, and we can't divide by zero, so we shouldn't divide by x.
The quadratic equation can be rewritten as:
x^2 - 7x = 0
x*(x - 7) = 0
(x - 0)*(x - 7) = 0
So the two solutions are x = 0 and x = 7, because x = 0 is a solution, we see that x can be equal to zero, so we can't divide by x.

om each drop-down menu. Megan's commute to work includes an 8-mile drive and a 21-mile train ride. This expression can be used to find the total time it takes Megan to get to work, where xis her average driving speed in miles/hour. 21
Answer: The answers are x+20 and 0.50 hrs
I just took the test so ik these are right
The total time it takes Megan to get to work,
⇒ (8 / x) + (21 / y)
where, x is her average driving speed in miles/hour. 2
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10
Given that:
Average driving speed = x mph
Miles driven to work = 8 mile
Miles by train to work = 21 miles
Average train speed = y
Hence, Total time taken to get to work is,
We know that;
⇒ Time taken = distance / speed
Hence,
⇒ Time taken = total distance / average driving speed
⇒ Total time taken = (8 / x) + (21 / y) hours
⇒ Total time taken = (8 / x) + (21 / y) hours

For each representation of a relationship, determine if it is a function or not.
Explain how you know with your answer.
(Giving brainliest to first and correct answer)
Answer:
e is a function; f is not a function
Step-by-step explanation:
All functions must pass the vertical line test. this means that the when those points are plotted, no two points are on the same vertical line. You can tell if they are on the same vertical line by their x-coordinate. If two points have the same x-coordinate, then they are on the same vertical line. This means that the if two points have the same x-coordinate in the relationship, it is not a function. In e, the x-coordinates are 0, 4, 8, and 3. In f, the x-coordinates are 0, 4, 0, and 6. In e, all the x-coordinates are different, so it is a function. In f, however, 0 is a repeated x-coordinate, so it is not a function.

Answer:
[tex]\displaystyle y<-\frac{1}{5}x+1[/tex]
Step-by-step explanation:
Graph of an inequality
The graph represented in the image is a line and we have two clear points through which the line passes.
Those points are (0,1) and (5,0).
The equation of a line can have the slope-intercept form:
y=mx+b
Substituting the point (0,1):
1=0+b
b=1
Substituting the point (5,0):
0=m(5)+1
Solving for m:
[tex]\displaystyle m=-\frac{1}{5}[/tex]
The equation of the line is:
[tex]\displaystyle y=-\frac{1}{5}x+1[/tex]
The origin belongs to the solution if we substitute (0,0) the inequality should stand:
0<1
Or:
0≤1
Since the line is dashed, the boundary line is not part of the solution
Thus the inequality is:
[tex]\boxed{\displaystyle y<-\frac{1}{5}x+1}[/tex]

A builder is building a rectangular deck with dimensions of 16 feet by
30 feet. To ensure that the sides form 90° angles, what should each
diagonal measure?
Answer:
Each diagonal should measure 34 feet to ensure that the sides form 90°
Step-by-step explanation:
The relation between the diagonal of the rectangle and its length and width is D = [tex]\sqrt{L^{2}+W^{2}}[/tex] ⇒ Pythagoras Theorem
∵ A builder is building a rectangular deck with dimensions of 16 feet
by 30 feet
∴ L = 16 feet
∴ W = 30 feet
→ By using the Pythagoras Theorem above to find its diagonal
∵ D = [tex]\sqrt{(16)^{2}+(30)^{2}}[/tex]
∴ D = [tex]\sqrt{256+900}[/tex]
∴ D = [tex]\sqrt{1156}[/tex]
∴ D = 34 feet
→ The diagonals of the rectangle are equal
∴ The length of each diagonal of the rectangle = 34 feet
Each diagonal should measure 34 feet to ensure that the sides form 90°
The graph shows the distance Arlene ran on Saturday preparing for a marathon. What is the rate of change and what does it represent?
Answer:
Rate of change = 6 miles per hour
Step-by-step explanation:
Rate of change of the line is represented by the slope of the line.
Formula to get the rate of change is,
m = [tex]\frac{\triangle y}{\triangle x}[/tex]
From the graph attached,
Given straight line is passing through two points (2, 12) and (4, 24).
Rate of change = [tex]\frac{y_2-y_2}{x_2-x_1}[/tex]
= [tex]\frac{24-12}{4-2}[/tex]
= 6
Rate of change of the line = 6 miles per hour
Therefore, rate of change of the graph will define the speed of Arlene.

Find the value of the integral from 2 to 6 of the natural log of x, dx using four rectangles of equal width, with each right end-point used to find the height of each rectangle.
Answer: Choice B.
ln(3) + ln(4) + ln(5) + ln(6)
=======================================================
Explanation:
Refer to the diagram below. It shows four rectangles each of base 1. Their height varies depending on the output of the natural log function.
More specifically the heights are ln(3), ln(4), ln(5) and ln(6) from left to right. Note how this corresponds exactly to the points on the y = ln(x) curve such that they are the upper right corners of the Riemann Sum rectangles. These corner points are points A,B,C,D.
Since each base is 1 unit wide, this means each rectangle's area is equal to the height. More thoroughly, we say that
area = base*height = 1*f(x) = f(x), where x takes on the values from {3,4,5,6}
Side note: As the diagram shows, we have an overestimate of the actual area under the curve from x = 2 to x = 5.
Sasha hasn’t won any of the 40 games she has played with her four friends so far. She wants to win at least 20%. How many does she need to win in a row to get 20%?
Answer:
10
Step-by-step explanation:
Given that Sasha has won 0 games in the 40 games she has played.
Let she needs to win x game in a row, so
Total game she played = 40 + x
The number of the game she won is x, which is 20% of the total game she played, so
x = 20% of (40+x)
[tex]\Rightarrow x = 0.2(40+x) \\\\\Rightarrow x = 8+0.2x \\\\\Rightarrow x-0.2x=8 \\\\\Rightarrow 0.8x = 8 \\\\\Rightarrow x = 8/0.8=10.[/tex]
Hence, she needs to win 10 games in a row.
