Help me find a 3rd degree binomial
Step-by-step explanation:
A binomial expression has two terms. For example, 4x + 5,
The degree of any polynomial refers to the term with the highest exponent on its variable. For example, In expression 4x + 5, the exponent of x is 1 so it is 1st degree polynomial and in the same way, for since the variable y has the highest exponent i.e., 2 therefore it is 2nd degree polynomial.
Now, third degree binomial with constant term 8 =
As it has two terms where first term is and second term is 8. Therefore, it is called binomial and since the highest exponent with variable x is 3, therefore it is third degree binomial with constant term of 8.

The sides of a square have length s
Write a formula for the perimeter
P=
Answer: p=side+side+side+side
Step-by-step explanation:The formula for the perimeter of a rectangle is often written as P = 2l + 2w, where l is the length of the rectangle and w is the width of the rectangle. The area of a two-dimensional figure describes the amount of surface the shape covers

Graph the equation on the coordinate plane.
y = 4x
What does 4x look like on a cordinate plain?
Answer:
Step-by-step explanation:
Step-by-step explanation:
The slope would be 4 (because in y=mx+b form, m = slope)
The y-intercept would be zero (0,0) since b = y-intercept, and there is no b in this equation.
From (0,0) you would rise four to get (0,4) and go over to the right one (1,4)
To make another point, you could go down 4 from (0,0) to get (0,-4) and to the left one to get (-1,-4)
Hope this helps.

A translation maps (x, y) to
(x – 5, y + 3). In which
quadrant does the point
(-3,-2) lie under the same
translation?
Answer:
second quadrant
Step-by-step explanation:
(x, y ) → (x - 5, y + 3 ) means subtract 3 from the original x- coordinate and add 3 to the original y- coordinate.
(- 3, - 2 ) ← in third quadrant
→ (- 3 - 5, - 2 + 3) → (- 8, 1 ) ← in second quadrant
2(x-7)-5x=13
how do i solve this
Answer:
x=-9
Step-by-step explanation:
2(x-7)-5x=13
Remove the parenthesis
2x-14-5x=13
Collect like terms
-3x - 14 = 13
Move the constant to the right
-3x=13+14
Calculate
-3x=27
Divide on both sides to get the answer
What is the answer to this problem?
The slope of a line is [tex]\frac{dy}{dx}[/tex]
where [tex]d[/tex] is the difference and [tex]y[/tex] and [tex]x[/tex] are the values.
In this case, the difference in [tex]y[/tex] is 10 and the difference in [tex]x[/tex] is 0
And division where the denominator being 0 leads to the answer being Undefined or Infinity as the line is directly on the [tex]y[/tex] axis.
if you had x nickels, how much money would you have?
Answer:
x(5) = number of cents
Step-by-step explanation:
If x = the amount of nickels you have, since 1 nickel is 5 cents, you multiply the number of nickels times 5 to get the number of cents. x(5). Examples: 5 Nickels= 5(5) = 25 cents. 7 Nickels = 7(5) = 35. Just plug in the number of nickles for x and solve. Hope this helped! If it did, please give me brainliest. Thanks!

Answer:
first pic, 2.5 pounds of peanuts cost $1, 17.5 pounds of peanuts cost $7, and the point (4,10) is also on the line. second pic, G.
Step-by-step explanation:
2.5 goes into 17.5, 7 times. then $7/7 means $1 for 2.5 pounds. that is true. second one they state the graph. the last one, if you calculate knowing 2.5 pounds is $1, then it is correct. for the second pic, i dont know but ill give you this im really sorry. draw a triangle from the two points getting a slope of 3. but this is negative so it's -3. the slope for the equation if it's perpendicular is 1/3 tho. wait i got it i think it's G since it's going to be perpendicular so if you draw it on, it would be positive.

Im so confused pls help
Answer:
2,3
Step-by-step explanation:
Let the first number be x
Hence, its next consecutive integer = x+1
[tex]Reciprocal\ of\ the\ first\ integer\ = \frac{1}{x} \\Reciprocal\ of\ the\ second\ integer\ = \frac{1}{x+1} \\\\As\ we\ are\ given\ that\ their\ sums\ are\ \frac{5}{6} ,\\\frac{1}{x} + \frac{1}{x+1} = \frac{5}{6} \\\\Through\ butterfly\ method\ of\ resolving\ the\ denominators\,\\\frac{(x+1)+x}{x(x+1)} = \frac{5}{6} \\\frac{2x+1}{x^2+x} =\frac{5}{6} \\6(2x+1)=5(x^2+x)\\12x+6=5x^2+5x\\\\Now, lets\ bring\ all\ the\ terms\ in\ the\ LHS\ to\ RHS.\\\\Hence,\\0=5x^2+5x-12x-6\\5x^2-7x-6=0\\[/tex]
By Factorizing the expression on the LHS. we get it equal to :-
[tex]5x^2-7x-6=0\\5x^2-10x+3x-6=0\\5x(x-2) + 3(x-2) = 0\\(5x+3)(x-2)=0[/tex]
Hence, we get two solutions for x, x=2, x= -3/5
As x is an integer, x=2 is the most suitable solution in this case.
Hence,
The numbers are 2,3

A water faucet runs at a rate of 4/5 gallon per 1/5 minute. What is the unit rate of the faucet? *
Answer:
4gallons per minuteStep-by-step explanation:
Step one:
the unit rate is the amount of water per unit of time
Given data
4/5 gallon to decimal= 0.8gallon
1/5 minute decimal= 0.2 minute
We are told that 0.8 gallons run in 0.2 minute
then x gallon will run in 1 minute
cross muliply we have
x=0.8/0.2
x=4
this means that in one minutes 4gallons will run in the faucet
The unit rate is 4gallons per minute
