Answer:
The equation represents a polynomial equation in which the variables X, y, and z are raised to the third power and are equal to a constant value "k".The degree of the polynomial is 3, meaning that the highest power of the variable is 3. The equation has no solution if k is not a sum of three cubes of real numbers.A polynomial equation is an equation that involves one or more variables raised to apower, or exponent, and can include constants and coefficients. The sum or difference of two or more such equations is also a polynomial equation. The degree of a polynomial equation is the highest power of the variable in the equation. For example, in the equation , the degree is 2 because the highest power of the variable X is 2.A polynomial equation of degree one is a linear equation, and a polynomial equation of degree two is a quadratic equation. The solutions of a polynomial equation of degree n will be n roots/solutions. The solutions can be real or complex numbers.

the question says: sal graphed a circle on the grid below.
sal translated the circle 6 units to the left and 7 units up. Which grid shows the result of this translation?
A. B. C. or D.
Answer:
the third choice
Step-by-step explanation:
take the center of the circle of the graph (4, -2)
move it 6 units to the left and 7 units up
so basically subtract 6 from 4
and add 7 to -2
to get
the center is (2, 5)

Compare the probabilities and determine which statement is true.
The theoretical probability of swimming, P(swimming), is one half, but the experimental probability is 34 over 60.
The theoretical probability of swimming, P(swimming), is 26 over 34, but the experimental probability is one half.
The theoretical probability of swimming, P(swimming), is 26 over 60, but the experimental probability is one half.
The theoretical probability of swimming, P(swimming), is one half, but the experimental probability is 26 over 60.
Answer:
The theoretical probability of swimming, P(swimming), is 26 over 60, but the experimental probability is one half.
Step-by-step explanation:
How to calculate the probability
The ratio between the number of favorable events and the total number of conceivable outcomes is known as the theoretical probability.
The experimental probability can be calculated mathematically using the following formula: Probability of an Event P(E) = Number of Times an Event Occurs / Total Number of Trials.
The experimental probability will be:
= Frequency for swimming / Total frequency
= 26 / 60
An airplane's distance traveled is monitored over time. The results are displayed in this table.
at is the constant of proportionality of this proportional relationship?
Answer: The Constant of Proportionality is 506.
Step-by-step explanation:
At 1 hour the plane traveled 560 Miles and at the second hour it had traveled 1,120 miles.
560+560=1,120 and if you add 560 to 1,120 you will get 1,680 which is the distance traveled at 3 hours. Therefore the answer is 560.

This is because if you find the GCF of 6 and 12 you will get 3.
3(p+m) hence why three is at the beginning.
you will then divide 6 and 12 by three and put them inside the parentheses with their corresponding variable.
3(2p+4m)
if you multiply this you will get
6p+ 12m
Answer:
Step-by-step explanation: for 3 you have yo find what is equivalent to 6p+12m so the answer is c. 6(p+12M) for 4 you are explaining what will happen if g is 1 and g is 3. for 5 you have to explain what is the constant rate.

Answer:
First Question's Answer = 7 + A
Second Question's Answer = (2 x 5) x 7
Step-by-step explanation:
The commutative property of addition states that numbers can be added together in any order without changing the resulting sum.
Therefore, A + 7 = 7 + A
The associative property of multiplication states the way in which three or more terms are grouped does not change the product.
therefore, 2 x (5 x 7) = (2 x 5) x 7

The triangle shown on the coordinate grid is translated 6 units to the right and 3 units down.
Which would be the measure of an angle of the resulting triangle?
(ignore the answer i choose lol) but pls help me
Answer:
75°
Step-by-step explanation:
Even if a triangle is translated, the original shape stays the same.
So, to get the answer, first add the first two angles of the triangle:
60 + 45 = 105
Then, subtract from 180, because 180 is equaled to all the angles added up on any triangle:
180 - 105 = 75.
So, you get 75°.

Answer:A two-step equation is an algebraic equation you can solve in two steps. Once you've solved it, you've found the value of the variable that makes the equation true. Example 1 We're given an equation and asked to solve for x x: 3 x + 2 = 14 3x + 2 = 14 We need to manipulate the equation to get x x by itself.

Chau is a software salesman. His base salary is $2300, and he makes an additional $50 for every copy of Math is Fun he sells.
Let P represent his total pay (in dollars), and let N represent the number of copies of Math is Fun he sells. Write an equation relating P to N. Then use this equation to find his total pay if he sells 26 copies of Math is Fun.
Answer: hope this helps ♡
P = $3600
Step-by-step explanation:
P = total pay
N = num of 'Math is Fun'
P = $2300 + $50(N)
P = $2300 + $50(26)
P = $2300 + $1300
P = $3600

Dillon walked around the rectangular field 3 times and covered a distance of 240m. Calculate the area of the field.
Answer:
80
Step-by-step explanation:
240÷3=80
16×5=80 so i think its 80
Answer: hope this helps ♡
The area of the field is 80m.
Step-by-step explanation:
3 times = 240m
1 time(s) = 80m (area - we divided 240 and 3 by 3)
A = ɭ × w
A = 80
w = 16
ɭ = ?
ɭ = 80 ÷ 16 = 5
A = 16 × 5 = 80 ✓
Which expression is equivalent to x+x+x+x+x+x?

∠1 and ∠2 are supplementary.
m∠1=124°
m∠2=(2x+4)°
What is the value of x?
Options:
13
26
40
36
41
Answer:26
Step-by-step explanation:Since angles 1 and 2 are supplementary, it follows that there sum is 180°.
On this note;
Sum of 1 and 2 is;
180 = 124 + (2x + 4)°
(2x + 4)° = 180 -124
2x = 56 -4
2x = 52
x = 26°.

Answer: 10x = 4 is x = 0.4.
To solve the equation 10x = 4, we want to isolate the variable x on one side of the equation.
First, we divide both sides of the equation by 10:
10x / 10 = 4 / 10
Simplifying:
x = 0.4
Therefore, the solution to the equation 10x = 4 is x = 0.4.

Select answers from the drop-down menus to correctly complete the statements.
The scale factor is A. 0.25 B 4
This represents A an enlargement B. a reduction
And its 0.2 And it grows to 0.8
Please help me
Answer:
The scale factor is 4, which represents an enlargement. And it grows from 0.25 to 0.8.
Step-by-step explanation:
The original hexagon has been enlarged by a scale factor of 4, meaning that each length and width of the original hexagon has been multiplied by 4. This means that the dimensions of the second hexagon are 4 times larger than the dimensions of the first hexagon.
In this case, the original side length of 0.25 has been multiplied by 4, resulting in a new side length of 0.25 * 4 = 1. This represents an enlargement of the original hexagon, since all dimensions have increased.
To summarize, the first hexagon has been scaled up by a factor of 4 to form the second hexagon, resulting in an enlargement of the original shape. The side length of the original hexagon has increased from 0.25 to 0.8, which represents the growth of the hexagon.
