Let's simplify step-by-step.
5x^3 + 3 + 2x^3 − x^2 + 1
= 5x^3 + 3 + 2x^3 + −x^2 + 1
Combine Like Terms:
= 5x^3 + 3 + 2x^3 + −x^2 + 1
= ( 5x^3 + 2x^3 ) + ( −x^2 ) + ( 3 + 1 )
= 7x^3 + −x^2 + 4
Answer:
= 7x^3 − x^2 + 4

If 50 grams of sweats cost $2.10,find the cost of 380 of sweats,giving your answer correct to the nearest 5 cent
Answer:
$15.95
Step-by-step explanation:
cost of 1 gram of sweet = $2.10 / 50 = 0.042
Cost of 380 g = 380 x 0.042 = $15.96
to the nearest 5 cent = 15.95

What is the domain ????????
Answer:
The domain of a function is the set of all possible inputs for the function.
Step-by-step explanation:
For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.
Hope this helped!

Solve for x.
2x + 24
3x - 26
x = [?]
Answer:
set them equal to eachother, i gotta look at my notes tho
Step-by-step explanation:
I think it's like this
3x-26=2x+24
We simpilfy the equation to the form which is simple to understand.
3x-26=2x+24
We move allterms containing X to the left and all others terms to the right
+3x-2x=+24+26
We simplfiy left and right sideof the eqution.
+1x=+50
We divide both sides of the equation by 1 to get x.
x=50

Jonathan plans to go to a carnival. The entrance is $3 and each ride cost 75 cents. Jonathan wants to spend no more than $20.
Answer:
22.6
Step-by-step explanation:
I assume you want to know how many rides he can do.
so
20$-3 = 17$
17÷.75 = 22.6 repeating
if you round up its about 23

Jess says that two of the three points below are on a line through the origin.
(3.8), (6, 21), and (9, 24)
Part A
Which two points could lie on the same line through the origin? Explain why. Explain why
the third point could not.
* I will give brainliest*
Answer:
(3, 8) and (9, 24) lie on the same line through the origin.
because (9, 24) is the result of dilatation of (3, 8) with scale factor 3.
(6, 21) is not the result, because 21 ≠ 2×8, even 6 = 2×3

Priya, variable "p", jumped 3 inches more than Xeno, “x”, in a high jump contest. Mai, “m”, jumped three times as many inches higher than Priya. If Mai jumped 14 inches, how many inches did Xeno reach? (You can use a tape diagram or hanger diagram to help solve this problem). ***EXPLAIN how you found your answer below:
Answer:
Xeno jumped 1 2/3 in
Step-by-step explanation:
if Mai jumped 3 times higher than Priya dividing Mai's 14 by 3 would get Priya's height. Then by subtracting 3 from Priya's height, which is 4 2/3, you get Xeno's height which is 1 2/3 in

The graph of a linear function is shown.
A coordinate plane with a straight line passing through (negative 4, 2), (0, 0), and (4, negative 2).
Which word describes the slope of the line?
positive
negative
zero
undefined
Zeros can be observed graphically or solved for algebraically. A linear function can have none, one, or infinitely many zeros. If the function is a horizontal line ( slope = [latex]0[/latex]), it will have no zeros unless its equation is [latex]y=0[/latex], in which case it will have infinitely many.
Answer:
answer is negative

The membership fee at a sports club was $600 per year. Each year, the membership fee increased by 7%. The cost of membership, y, can be modeled by the equation y=600(1.07)^x, where x is the number of years.
How many years will it take for the cost of the membership to be $900?
Choose the answer that gives the correct logarithmic equation and answer.
x=log1.5(1.07)
x=6
x=log1.07(1.5)
x=6
x=log(1.51.07)
x=1
x=log(1.071.5)
x=1
Answer:
x = log1.5/log1.07
x = 6
Step-by-step explanation:
900 = 600(1.07)^x
Divide both sides by 600
1.5 = 1.07^x
Take the log of both sides
log1.5 = x log1.07
Divide both sides by log1.07
log1.5/log1.07 = x
x = log1.5/log1.07

Casey polled 50 seventh grade students. He asked who they planned to vote for as class president. Thirty students said they would vote for Lynne. Twenty said they would vote for Marcus.
Use this probability to predict how many seventh graders in their class of 450 students will vote for Lynne
Answer:
270 students
Step-by-step explanation:
First, you need to do a ratio.
30 x
------- = --------
50 450
In order to solve this, you need to multiply 450 times 30 and that equals 13500. 13500 divided by 50 is 270. That means that about 270 students will vote for Lynn.

There is a bag of tiles where 8 are red, 5 are blue, 4 are orange, and 3 are green. If one is picked at random, replaced, and another marble is picked, what is the probability that they are both orange? in a percent or fraction
Answer:
There would be 1/25 chance (4%).
Step-by-step explanation:
So there's 4 orange marbles and there's 20 total marbles since:
8 Red + 5 Blue + 4 Orange + 3 Green
With this, the chance of drawing an orange marble is 4/20, or 1/5. Because the marble is replaced back after being picked, the same chance would occur for the second picking.
To combine these chances, multiply them together for the answer.
1/5 * 1/5 = 1/25 (4%)

Find the 8th term 50,20,8
Answer:
0
Step-by-step explanation:
Answer:
0.08192
Step-by-step explanation:
Given 50, 20, 8, ...
The sequence is geometric in nature
The nth term of the geometric sequence is exoressed as;
Tn = ar^{n-1}
a is the first term = 50
r is the common ratio = 20/50 = 8/20 = 2/5
n is the number of term = 8 (since we need the 8th term)
Substitute
T8 = 50(2/5)^{8-1}
T8 = 50(2/5)^7
T8 = 50(128/78,125)
T8 = 0.08192
Hence the 8th term is 0.08192.
