whats a rational number
Answer: A rational number is a number that can be express as the ratio of two integers. Likewise, any integer can be expressed as the ratio of two integers, thus all integers are rational.
Example:17 and −34 are rational numbers

Brainiliest if right 3. Solve the following equation.
-y/7 = 35
A. -245
B. 5
C. 245
D. -5
Answer:
The answer is -245
Step-by-step explanation:
You solve for y by simplifying both sides of the equation, then isolating the variable, of which is -245.
Answer:
B.

I am not sure if this is right
Match the equation and the description non-proportional Realationship
Answer:
A. [tex]y =\frac{7}{8}x+1[/tex]
B. [tex]y = -10x[/tex]
C. [tex]y = 2.5x - 7[/tex]
D. [tex]y = 1.2x[/tex]
E. [tex]y = -5x -8[/tex]
Step-by-step explanation:
Let the descriptions be A to E.
First, we need to note the followings.
An equation is of the form
[tex]y = mx + b[/tex]
[tex]m = slope[/tex] and [tex]b = y\ intercept[/tex]
A. Non proportional graph with positive y intercept
From the list of options, only
The slope of [tex]y =\frac{7}{8}x+1[/tex] is positive
and y intercept is also positive
B. Negative slope and pass through the origin.
Negative slope means m is negative
From the list of options
[tex]y = -10x[/tex] and [tex]y = -5x -8[/tex]
Origin implies (0,0)
i.e: [tex]x = 0[/tex] and [tex]y = 0[/tex]
For y = -10x
[tex]0 = -10 * 0[/tex]
[tex]0 = 0[/tex] --- This is true
For [tex]y = -5x -8[/tex]
[tex]0 = -5 * 0 - 8[/tex]
[tex]0 = 0 - 8[/tex]
[tex]0 = -8[/tex] --- This is not true
Hence:
[tex]y = -10x[/tex] fits this description
C. Increases from left to right and b is negative
For b is negative, we have the following:
[tex]y = -5x -8[/tex] and
[tex]y = 2.5x - 7[/tex]
An increment from left to right, means the slope is positive.
So, we have:
[tex]y = 2.5x - 7[/tex]
D. Positive slope and contains (0,0)
From the options, we have the following functions left:
[tex]y = -5x -8[/tex] and
[tex]y = 1.2x[/tex]
But [tex]y = 1.2x[/tex] has a positive slope and also contain (0,0) because
[tex]0 = 1.2 * 0[/tex]
[tex]0 = 0[/tex]
E. Negative m and Negative b
[tex]y = -5x -8[/tex] has these descriptions

Can anyone help me with this problem? It's a review.
You can ignore the other questions I just need help on this one.
Answer:
The point (0,-2) is the solution to the problem. Substitue 0 into x, the answer is -2 which matches f(x), or y value.
Step-by-step explanation:
Use the diagram below in which P is the incenter of JKL, PN =21 and ML=27 . Find PO, LO, and PL
Answer:
1. PO = 21
2. LO = 27
3. PL = 34.2
Step-by-step explanation:
1. Since P is the incenter, that means it is equidistant to each side at a right angle. As a result PN, PO, and PM are equal to each other.
We know that PN is 21. Since PN and PO are equal to one another, PO = 21.
2. ML is equal to LO. ML is 27, so LO is also 27.
3. To get PL you will have to do the Pythagorean Theorem. Square the legs and set it equal to the hypotenuse squared.
* It should be: 27^2 + 21^2 = x^2.
Once you solve and round to the nearest tenth, you will get 34.2.
someone please solve and find the corresponding angles thanks

g =
Answer:
g = 1/2
Step-by-step explanation:
Here, we want to calculate the value of g from the given equation
9 + 3.5g = 11-0.5g
11-9 = 0.5g + 3.5g
2 = 4g
g = 2/4

Regina orginally packed 10 goodies bags for her birthday party. She found out the day before the party that a few more friends would be attending so she made three additional bags for the party. Write an algebraic expression to represent the total number of candies and toys that Regina made for her birthday party.
Answer:
c + t = 13
Step-by-step explanation:
Regina originally packed 10 goodies bags for her birthday party. She found out the day before the party that a few more friends would be attending so she made three additional bags for the party. Write an algebraic expression to represent the total number of candies and toys that Regina made for her birthday party.
Let the number of candies = c
Let the number of toys = t
The total number of goodies bags she made = 10 + 3 = 13 goodie bags
Hence,
The total number of candies and toys that Regina made for her birthday party
c + t = 13

5. The scale on the map of a park is 5 in.: 3 mi. The distance from the entrance of the park to the playground is 9 miles. How many inches long is the distance on the map?
Answer:
15 inches
Step-by-step explanation:
Here, we have a scale of 5 inches to 3 miles
We have 9 miles here, we now want to get the amount of corresponding inches
Let the corresponding inches be x
5 inches to 3 miles
x inches to 9 miles
That means ;
x * 3 = 5.* 9
x = 45/3
x = 15 inches

Interpreting Velocity vs Time Graphs
A graph titled velocity versus time has horizontal axis time (seconds) and vertical axis velocity (meters per second). A line has 3 straight segments. Line segment A runs from 0 seconds 0 meters per second to 4 seconds 40 meters per second. Then segment B runs to 9 seconds 40 meters per second. Then segment C runs to 10 seconds 10 meters per second.
Use the graph to determine acceleration and velocity.
Which segments show acceleration?
What is the velocity of segment B?
Choices for the first question:
A. A and B
B. A and C
C. B and C
Choices for the second question:
A. 8 m/s

consider the equation 2,900=250+132.50T in this situation, what does the solution to this equation tell us?
Answer:
value of T = 20
Step-by-step explanation:
[tex]2900=250+132.50T\\2900-250=132.50T\\2650=132.50T\\2650/132.50=T\\20=T[/tex]
If this is the whole question so we can say that the value of T is 20 if there is more to the question than it help us tell what T signifies other than that it's just a plain value.
Which points define the solution set of this linear-quadratic system of equations
Answer:
At point C (-0.5,2)
At point E (1,5)
Step-by-step explanation:
The points that defines the linear quadratic equation system is as follows:
As we can see that the point E and Point C are the solutions set that have an intersections between the parabola i.e. blue and the red line also they are on the both curves at the same time. In addition to this, their coordinates satisfy the both equations in the similar time
Hence, the same is to be considered
