What are like terms? (Pls give an example of one too)
Answer:
Step-by-step explanation:
Like terms are terms that have the same variable raised to the same exponent. For example, 7z and 2z are like terms because they have the same variable, z, and are raised to the same exponent, 1. 5x² and 10x are not though, because the first one is raised to a power of 2, whereas the latter is only raised to a power of 1. And numbers with different variables, like 7x and 3z, are not either.
Answer: like terms are terms that have the same variables and powers
For example: 3x and 4x are like terms because they both are x and only x. 12xy and 4y would not be like terms because they don’t share the same variable. if it was 5x ² and 8x ² they would be like terms. i hope this helps!

Last week Rachel power watch 2 3/5 miles per day on each of the seven days during the same week she also jobbed 5 3/4 miles per day on 4 days what was the total amount of Miles Rachel power walk and Jog last week
Answer:
41.2 miles
Step-by-step explanation:
The computation of the total amount of miles rachel walk and jog last week is as follows;
Unit rate per day is
= 2 3 ÷ 5
= 13 ÷ 5
= 2.6 miles
In 7 days, she walked
= 2.6 miles × 7 days
= 18.2 miles
Now for four days, the unit per day is
= 5 3 ÷ 4 × 4
= 23 ÷ 4 × 4
= 23 miles
So, the total amount of miles would be
= 18.2 miles + 23 miles
= 41.2 miles

Which of the following rational functions is graphed below?
Answer: Choice C [tex]f(x) = \frac{1}{x(x+4)}[/tex]
========================================================
Explanation:
The vertical asymptotes are the red dashed lines. They are x = -4 and x = 0. Think of them as electric fences that the graph cannot touch or cross. The curve can only get closer and closer.
The vertical asymptote is due to a division by zero error.
When x = 0, the denominator x(x+4) turns into 0 since
x(x+4) = 0(0+4) = 0*4 = 0
Similarly, when x = -4, the denominator is also zero
x(x+4) = -4(-4+4) = -4*0 = 0
So if x = -4 or x = 0, then we have a division by zero error and that's what produces the vertical asymptotes at those locations shown on the graph.
This is why the answer is choice C. [tex]f(x) = \frac{1}{x(x+4)}[/tex]
solve the following system of equations
Michelle lives 4.5 miles from work. Kelly lives 5.6 kilometers from work. Staci lives 4,200 meters from work. Kyle lives 670,000 centimeters from work.
Answer:
Michelle < Staci < Kelly < Kyle
Kyle is the greatest distance from work, while Michelle is the closest to work.
Step-by-Step Explanation:
1 kilometer = 0.62137119 mile(s)
4.5 miles = 0.62137119 × 4.5 = 2.79617036 kilometers
4,200 meters = 4.2 kilometers
670,000 centimeters = 6.7 kilometers
So,
Michelle = 2.8 kilometers (rounded up)
Kelly = 5.6 kilometers
Staci = 4.2 kilometers
Kyle = 6.7 kilometers
So,
Michelle < Staci < Kelly < Kyle
Kyle is the greatest distance from work, while Michelle is the closest to work.

Which method will NOT get you to the point (4,3.5)?
A. Starting at the origin, go 3.5 spaces to the right and then 4 spaces up.
B. Starting at the origin, go 3.5 spaces up and then 4 spaces to the right.
C. Starting at the origin, go 4 spaces to the right and then 3.5 spaces up.
D. Put one finger on 4 on the x-axis, and put another finger halfway between 3 and 4 on the y-axis. Move the first finger up and the second finger to the right until they meet.
Answer:
A. Starting at the origin, go 3.5 spaces to the right and then 4 spaces up.
Step-by-step explanation:
if you were to plot this then the point would be (3.5,4) instead of (4,3.5)
Starting at the origin, go 3.5 spaces to the right and then 4 spaces up will not get you to the point (4,3.5) but will get you (3.5, 4). The correct option is A.
What are coordinates?Coordinates are a pair of integers (Cartesian coordinates), or occasionally a letter and a number, that identify a certain place on a grid, often referred to as a coordinate plane.
We have the point (4, 3.5).
And let the point (x, y).
By comparing,
we get,
x = 4 and y = 3.5
That means, the value in the x coordinate is 4 and y coordinate is 3.5.
As the signed distance from the origin in the direction along the x-axis, the first value x is known as the x-coordinate (or x-component). The x-coordinate indicates the distance from the y-axis to the right (if x is positive) or left (if x is negative).
Additionally, the y-coordinate indicates how many steps are needed to up either positively or negatively on the y-axis.
So, the point is 4 point right from the origin and 3.5 point up from the origin.
Therefore, starting at the origin, go 3.5 spaces to the right and then 4 spaces up will not get you to the point (4,3.5)

Linear Equation, Need Solved Asap <3
Step-by-step explanation:
y = 5x - 4
When x = 0, y = 5(0) - 4 = -4.
When x = 1, y = 5(1) - 4 = 1.
When x = 2, y = 5(2) - 4 = 6.
The 3 ordered pairs we have are (0,-4), (1,1) and (2,6).
We now check the point (-5,-29):
(-29) : 5(-5) - 4
-29 : -25 - 4
-29 : -29 => -29 = -29.
Since Left hand side = Right hand side, the point (-5,-29) is a solution.
Answer:
1. (1,1) (2,6) (3, 11)
2. Yes
Step-by-step explanation:
1. 5(1)-4 = 5-4 = 1
5(2)-4 = 10-4 = 6
5(3)-4 = 15-4 = 11
(I just chose 3 simple x values and plugged them into the equation to get the y values then wrote it as an ordered pair)
2. 5(-5)-4 = -25-4 = -29
-29 = -29
(Same as number 1 but I used the given x value then I checked if the y value I got matched the ordered pair)

Malcolm is filling bags with rice. He starts with a 5 1/4 pound container of rice and fills each bag with 5/8 pound of rice. How many bags of rice can malcolm fill??
Answer:
part 1: Divide 5 1/4 pound by 5/8 pound
part 2: 8 bags
part 3: 2/5 of another bag
Step-by-step explanation:
total number of bags that can be filled equals total rice divided by the amount of rice per bag
=5 1/4 divided by 5/8
=(21/4)/(5/8) turn the mixed number into improper fraction
=(42/8)(5/8) common denominator
=42/5
=8.4 bags, but can only fully fill 8 bags
2/8 pounds of rice are left over after filling 8 bags, and 2/8 pounds is equal to
2/5 of another bag
(2/8)/(5/8)
=2/5 simplify

Write an equation in whatever form you choose with the given characteristics Perpendicular to y= -1/2x - 8 and passes through: (7. -6)
Answer:
[tex]y+ 6 = 2 (x-7)[/tex]
Step-by-step explanation:
1) Lines that are perpendicular have slopes that are opposite reciprocals of each other. y = -1/2x - 8 is in y = mx + b form, in which the number in place of m represents the slope. So, the slope of y = -1/2x - 8 is -1/2. The opposite reciprocal of it would be (remember to flip the fraction and reverse the sign) 2. So, 2 is the slope we need for the answer.
2) When you know a point that the line must pass through and its slope, you can use point-slope form ([tex]y-y_1 = m (x - x_1)[/tex]) to write an equation. [tex]x_1[/tex] and [tex]y_1[/tex] represents the x and y values of the point the line intersects, and m represents the slope. So, substitute 2 for m, 7 for [tex]x_1[/tex], and -6 for [tex]y_1[/tex].
[tex]y-(-6) = 2 (x- 7)\\y + 6 = 2 (x-7)[/tex]

[tex](5\sqrt{5})^{-2x+1} = \frac{1}{5} * 125^{x-3}[/tex]
Step-by-step explanation:
(5√5)^(1-2x) = 1/5 * 125^(x-3)
(5^1.5)^(1-2x) = 5^(-1) * 125^x / 125^3
5^1.5 / 5^3x = 5^(-1) * 5^(3x) / 5^9
5^1.5 / 5^3x = 5^(3x) * 5^(-10)
5^(1.5 - 3x) = 5^(3x - 10)
=> 1.5 - 3x = 3x - 10
=> 6x = 11.5
=> x = 23/12.

Graph the image of the figure after a dilation with a scale factor of 3 centered at (2, −7).
Use the Polygon tool to graph the quadrilateral by connecting all its vertices.
Answer:
Step-by-step explanation:
Each point moves 3 times the distance from the center of dilation that it was.
You can compute the new coordinates by ...
L = P - O . . . . . the length from O to P is P-O for some point P and origin O
Then 3 times that distance is
3L = 3P -3O
We want to find the point P' that is 3L from O, so we add this distance to the coordinates of O. We get ...
P' = 3L +O = 3P -3O +O
P' = 3P -2O
So, for the lower left point A(-2, -7), the dilated image point A' is ...
A' = 3(-2, -7) -2(2, -7) = (-6, -21) +(-4, 14) = (-10, -7)
That is, ...
A' = 3A +(-4, 14)
The coordinates of the remaining points can be found similarly.

On a graph, it is usually fairly easy to count the grid squares in each direction between the point of interest and the center of dilation. The image point is 3 times the distance in each direction (horizontally, vertically).
