√π
6.565656...
0.23
0.32416....
-5 3/8
We need to find which of the following are rational numbers.
What is a rational number?The numbers that can be written in the form of p/q where q ≠ 0 are called rational numbers.
Rational numbers are terminating and recurring numbers.
Example: 2, 1/4 = 0.25, 1.333333333
Check the following numbers.
- 5/6
= 0.8333333
we see that 3 is repeating.
It is recurring so it is a rational number.
- √π
= 22/7
= 3.1428571...
It is non-terminating so it is not a rational number.
- 6.565656...
We see that 56 is repeating.
It is recurring so it is a rational number.
- 0.23
It is terminating.
It is a rational number.
- 0.32416....
It is non-terminating so it is not a rational number.
-5 3/8
= 43/8
=5.375
It is terminating.
It is a rational number.
Thus 5/6, 6.565656.., 0.23, -5 3/8 are rational numbers.

What value of Y makes the equation true ?
Answers
Answer:
y = -5/2 or -2.5
Step-by-step explanation:
3y + 4 = -y - 6
add y to both sides
4y + 4 = -6
subtract 4 from both sides
4y + 4 - 4 = - 6 - 4
4y = -6 - 4
4y = -10
divide both sides by 4
4y/4 = -10/4
y = -10/4
y = -5/2 or -2.5

Answers
Answer:
x=6
Step-by-step explanation:
rearrange terms, subtract 6 from both sides, simplify, subtract 2x from both sides, simplify, divide both sides by -5, and finally you get 6.
Answer:
x=6
Step-by-step explanation:
6 - 3x = 2x - 24
move the x together and the numbers together
REMEMBER: when you move a something from one side of the equation (not including multiplication and division) to the other, change the sign in-front of it (+ or -)
NOW CONTINUE WITH THE PROBLEM -->
-3x-2x = -24 - 6
now subtract,
-5x = -30
and divide -30 by -5
Since there are 2 negative numbers, the result would be positive -->
and for x, you would get:

Answer:
8) the ordered pair is a solution, 9) the ordered pair is not a solution
Step-by-step explanation:
8) if you plug in the values of x into the equation, which is 7, 7+9 equals to 16, which is the y value in the ordered pair
9) the same is for this question, if you plug in the x value into the equation, which is 5, 2(5)+8 is equal to 10+8 which is equal to 18. This isn't equal to the y value in the ordered pair
Answer:
8.) yes it is a solution because if plug in 7 for x and 16 for y you get 16=7+9 which equals 16
9.) No it is not a solutions because if you plug in 28 for y and 5 for x you 28=2(5)+8 and then when you multiply the 2 and the 5 you get 28=10+8 and 10+8 equals 18 and 28 and 18 are not equal

Which equation represents the relationship between the x-values and y-values in the graph?
Answers
The equation of line passes through the points (0, -5) and (5, -2) will be;
⇒ y = 3x/5 - 5
What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (0, -5) and (5, -2).
Now,
Since, The equation of line passes through the points (0, -5) and (5, -2).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (- 2 - (-5)) / (5 - 0)
m = 3 / 5
m = 3/5
Thus, The equation of line with slope 3/5 is,
⇒ y - (-5)= 3/5 (x - 0)
⇒ y + 5 = 3x/5
⇒ y = 3x/5 - 5
Thus, The equation of line passes through the points (0, -5) and (5, -2) will be;
⇒ y = 3x/5 - 5
