which pair of terms are not like terms?
A. 4a and 7a
B. 3p^2q and -p^2q
C. 2mn and mn^2
D. -x and 3x
Answer:
C.
Step-by-step explanation:
Like terms must have exactly the same variables and exactly the same exponents.
In C., you have mn and mn^2. That makes the variable parts not the same, so they are not like terms.
Answer: C.
Divide. Give the quotient and remainder. 47 ÷ 5
Answer:
9 Remainder 2 which is also 9.4
Step-by-step explanation:
The closest to a full number would be 9. So do 9*5 to get 45. With a remainder of 2.
Brainliest maybe? I need one more and I level up in rankings.
Answer:
9 remainder 2.
Step-by-step explanation:
5 * 9 = 45
47 - 45 = 2.

Solve for y,if 3+3y=1–13y
Step 1: Simplify both sides of the equation.
3+3y=1−13y−9
3+3y=1+−13y+−9
3y+3=(−13y)+(1+−9)(Combine Like Terms)
3y+3=−13y+−8
3y+3=−13y−8
Step 2: Add 13y to both sides.
3y+3+13y=−13y−8+13y
16y+3=−8
Step 3: Subtract 3 from both sides.
16y+3−3=−8−3
16y=−11
Step 4: Divide both sides by 16.
16y
16=−11/16
y=−11/16
Answer:
y=−11/16

The proportional equation that represents the situation is:
y = 13x
What is a proportional relationship?A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
[tex]y = kx[/tex]
In which k is the constant of proportionality, also called slope.
In this problem, the points (number, cost) are: (3,39), (5,65) and (8,104), hence the slope is given by:
[tex]k = \frac{39}{3} = \frac{65}{5} = \frac{104}{8} = 13[/tex]
Hence, the equation is:
y = 13x.

The slope of the linear equation is $13 per necklace.
Linear equationA linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope (rate of change), and b is the y intercept (initial value of y).
Let y represent the total charge for x number of necklaces.
From the table, using (3, 39) and (8, 104), hence:
m = (104 - 39) / (8 - 3) = 13
The slope of the linear equation is $13 per necklace.

proves that the sum of
5 consecutive natural numbers is divisible by 5
Answer:
n = 5m + 10 = 5(m + 2), since m + 2 is an integer, then the n is divisible by 5.
Step-by-step explanation:
Answer:
Natural numbers are simply positive integers. For now, refer to the middle number (the third number), as x. Thus, the numbers are: x - 2, x - 1, x, x + 1, and x + 2. Simply add all these numbers to get 5x, a number that is divisible by 5. As such, you can conclude that any 5 consecutive numbers are divisible by 5, and the quotient would be the third, or middle number.

Write the expression as a power and evaluate it. 8*2^7
Answer:
1024
Step-by-step explanation:
The expression can be written as [tex]8 * 2^7[/tex]
What is power?An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.
Example: The standard form of the polynomial 5 + 2x + x² is expressed.
We shall first determine the polynomial's degree before expressing it in standard form.
The degree of the provided polynomial is two. Write the phrase containing the polynomial's degree.
Given:
8*2^7
The above expression can be written as
[tex]=8 * 2^7[/tex]
= 8 x 128
= 1024.
Hence, the expression can be written as [tex]8 * 2^7[/tex]

Answer:
[tex]2x^3+x^2-8x-4=(2x+1)(x+2)(x-2)[/tex]
Step-by-step explanation:
Let's collect [tex]x^2[/tex] between the first two terms, and -4 between the last two:
[tex]2x^3+x^2-8x-4=x^2(2x+1) -4 (2x+1)[/tex]
At this point you should see there is a common factor[tex]2x+1[/tex]between both terms, then let's collect that:
[tex]2x^3+x^2-8x-4=x^2(2x+1) -4 (2x+1) = (2x+1)(x^2-4)[/tex]
Final step is recognizing a difference of squares (x and 2) in the second bracket, to end up our work!
[tex]2x^3+x^2-8x-4=x^2(2x+1) -4 (2x+1) = (2x+1)(x^2-4) =(2x+1)(x+2)(x-2)[/tex]
Step-by-step explanation:
[tex]f(x) = {2}^{3} + {x}^{2} - 8x - 4[/tex]
[tex] {x}^{2} (2x + 1) - 2(2x + 1) = 0[/tex]
[tex](2x + 1)( {x}^{2} - 2)[/tex]
[tex]x = \frac{ - 1}{2} \\ x = \sqrt{2} [/tex]

f(x)= -1/2x+1
Step-by-step explanation:
The slope is negative because the graph goes up then to the left, making it negative. The slope is also 1 half because the slope is measured by rise over run. It rises once, then goes to the left twice. 1/2. It's also plus 1 because the graph cross the y-intercept at positive 1.

What is the equation of the line in point slope form given a slope of -12 and a point of (-4,
-5)?
Answer:
The equation of a line in point-slope form is y-Y1=m(x-X1). ”m” is the slope and (X1,Y1) is a point.
So, the equation in point-slope form is y+5=12(x+4).

Step-by-step explanation:
Substituting the values into the formula,
l = 500pi ft^2-(15ft)^2pi/pi
l = 500ft^2-225ft^2 = 275
Answer:
275 ft
Step-by-step explanation:
[tex]l=\frac{S-\pi r^{2} }{\pi }[/tex] where S = 500πft², r = 15ft
