Hi
Which of these tables represents a function?
Answer:
Table W represents a function
Step-by-step explanation:
Mathematically, for us to have a function , no two y-values can take a single x value
But it is possible that two x-values have a single y value
So let us make a selection from the table
We have the correct option as;
W
In the equation x - 9y = 21, which variable should you isolate?
We will isolate the variable y to make the equation in the slope-intercept form.
And the equation is y = x/9 - 7/3.
What is linear equation?Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.
Given:
A linear equation,
x - 9y = 21.
We will isolate the variable y to make the equation in the slope-intercept form.
9y = x - 21
y = x/9 - 7/3
Therefore, we will isolate the variable y.

100(x-3) = 1,000
What’s the value of x?
Answer:
x=13
Step-by-step explanation:
100(x-3)=1000, divide both sides by 100
100/100(x-3)=1000/100
x-3=10, add three to both sides
x-3+3=10+3
x=13

1. 12m + 24m
2. 90a - 30a
3. 14b + 15b + 8
4. 58d + 25 - 22d
5. 3(14 + 15f) + 79
6. 20(18 + 5t) - 47 + 28t
Step-by-step explanation:
These problems are about like terms. Those are terms that are alike (same variables) but the coefficients (numbers in front) can be different.
1. 12m + 24m = 36m
2. 90a - 30a = 60a
Example: 6k + 8k + 10 = 14k + 10 (the part of the expression that's just a number does not combine with the parts that have variables).
3. 29b + 8
4. 36d + 25 (the terms with d in them combine--they don't have to be back-to-back)
5. This is about the Distributive Property; first multiply 14 + 15f both by 3, then look for opportunities to combine like terms.
3(14 + 15f) + 79 = 42 + 45f + 79 = 121 + 45f
6. 20(18 + 5t) - 47 + 28t = 360 + 100t - 47 + 28t
= 313 + 128t

Which equation has the same solution as x2 + 16x – 11 = 4?
Answer:
x^2 + 16x - 15 = 0.
Step-by-step explanation:
x^2 + 16x – 11 = 4 Subtract 4 from both sides:
x^2 + 16x - 15 = 0 is one equation with the same roots.
Also any equation which is a multiple of the above will have the same roots. For example if we multiply by 3:
3x^2 + 48x - 45 = 0.

find the value of x then find the angle measures of the polygon 65, x, (x-5)
Answer:
x = 60
Step-by-step explanation:
Assuming that there are no secret angles unmentioned, the figure in question is a triangle, as it has 3 angles. With this knowledge, we also know that a triangle contains 180°. So, we can do the following to solve for x.
65 + x + (x - 5) = 180
2x + 60 = 180
2x = 120
x = 60

How do I find the volume of this?
Answer:
(64+320π) cm^3
Step-by-step explanation:
The volume of a cube is the length*width*height, so
the volume of this cube is 4*4*4=64 cm^3
The volume of a cylinder is the base*height
The base of a cylinder is the area of a circle, which is π*the radius of the circle squared
The diameter of the circle base is 16, and the radius is half the diameter, so it is 16/2=8.
The area of the base of the cylinder is π8^2=64π
Now, multiply the base by the height, 5
64π*5=320πcm^3
We now have the volume of the cube and the volume of the cylinder, so now we just add them:
(64+320π) cm^3

To find 25% of 1375, multiply 0.25x1375.
0.25x1375
=343.75
Or you can use fractions!
25%=0.25
0.25=1/4
Divide 1375 by 4
=343.75
25% of 1375 is equal to 343.75
explain why 2^0 is equal to 1.
Answer and Step-by-step explanation:
Anything that is to the power of 0 is equal to 1. This is why 2 to the power of 0 is equal to 0.
0 is the only number such that for any number x, x + 0 = x. So, the reason that any number to the zero power is one is because any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, 1.

4x – 5 + 2(x – 3) = 12x + 7
X=
Answer:
-3
Step-by-step explanation:
4x - 5 + 2(x - 3) = 12x + 7
4x - 5 + 2x - 6 = 12x + 7
4x + 2x - 5 - 6 = 12x + 7
6x - 11 = 12x + 7
collect like terms
6x - 12x = 7 + 11
-6x = 18
-x = 3
x = -3

To find a y term, find the absolute value of the x term (|x|).
Absolute value - the distance between 0 and a number. The absolute value of a number will always be equal to the positive form of the number (if it isn't already positive).
Some examples: The absolute value of 18 is 18. The absolute value of -10 is 10.
Find the absolute value of each x term to find y:
x ⇒ y
-2 ⇒ 2
-1 ⇒ 1
0 ⇒ 0 (the absolute value of 0 is always 0)
1 ⇒ 1
2 ⇒ 2

How many combinations with repetition are allowed if n = 7 and r = 2?
a. 21
b. 14
c. 49
d. 28
The combinations with repetition are allowed is equal to 28.
Here we have N=7 r=2
We have to determine the combination of repetition
What is the combination?
A combination is a selection of items from a set that has distinct members, such that the order of selection does not matter.
The combinations with repetition are allowed if n = 7 and r = 2
So 7x2=14
7x3=21
7x4=28
Therefore the combinations with repetition are allowed is equal to 28.

Let us find the perfect cubes between 1 to 100.
We know that, 1
3
=1,2
3

3
=64 and the rest numbers i.e. 4,5,6,.... have their cubes greater than 100.
So, only these four numbers have their cubes between 1 to 100.
Thus, there are 4 perfect cubes from 1 to 100.
Now, let's find the cubes between −100 to 0

Two angles which are on opposite sides of the transversal and between the parallel lines and do not share the same vertex. They are congruent.
Answer:
Interior angles are congruent.
Step-by-step explanation:
We see that angles 3,4,5,6 are between the two parallel lines . These angles are called interior angles.
Angles 3,6 are opposite and do not share the same vertex.
Similarly angles 4 and 5 do not share the same vertex.
They are congruent.
If we look closely we see that angles 3 &4 and angles 5&6 are supplementary angles.
i.e they together make up the 180 degrees on the straight line.
On the outer sides of the parallel lines angles 1&2 and angles 7 & 8 are exterior angles
which also make supplementary angles on the parallel lines.
From the diagram we see that
∠ 5= ∠7
and
∠6 = ∠ 8
as the corresponding angles are equal
∠8=∠3
∠7=∠4
As they are opposite angles
Similarly
∠1=∠6
∠2=∠5 ( opposite angles)
From above
∠5=∠7
but ∠7= ∠4
therefore
∠ 5= ∠4-----------------A
Also
∠6 = ∠ 8
but ∠8=∠3
therefore
∠6=∠8----------------------B
From An and B we conclude interior angles are congruent
