Solve for x
3x=4y-10
x=(4y-10)/3
solver for y
3x=4y-10
rewrite as 4y-10=3x
4y-10+10=3x+10
4y=3x+10
y=(3x+10)/4

Which of the following is a monomial A. 12c B. C^2 -16 C. c^2+c+6 D. C^3 +4c^2 -12c + 7
abruzzese [7]
Answer is A. 12c
A monomial only consists of one term (12c), 
Binomials consist of two terms (c^2 - 16)
Trinomials consist of three terms (c^2 + c + 6)

An easy way of remembering which is which is to look at the prefixes. 
Mono= 1
Bi= 2
Tri= 3

A pendulum swings 80 cm on its first swing, 76 cm on its second swing, 72.2 cm on its third swing, and 68.59 cm on its fourth sw
Kisachek [45]

Answer:

a_{n} = 80*(0.95)^{n-1}

Step-by-step explanation:

Geometric sequences:

The nth term of a geometric sequence is given by the following equation.

a_{n+1} = ra_{n}

In which r is the common ratio.

This can be expanded for the nth term in the following way:

a_{n} = a_{1}r^{n-1}

In which a_{1} is the first term.

In this question:

a_{1} = 80, r = \frac{68.59}{72.2} = \frac{72.2}{76} = \frac{76}{80} = 0.95

a. If the pattern continues, what explicit formula can be used find the distance of the nth swing?

a_{n} = a_{1}r^{n-1}

a_{n} = 80*(0.95)^{n-1}

8-inch boxes are stacked next to 6-inch boxes. What is the lowest height at which the two stacks will be the same height?​
Vladimir79 [104]

Answer:

<u>The lowest height at which the two stacks will be the same height is 24 inches.</u>

Step-by-step explanation:

For answering this problem, we have to find out the lowest common multiple of 6 and 8, listing its prime factors, this way:

6 = 3 * 2

8 = 2 * 2 * 2

Now, we multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

Therefore, we have:

2 : 3 times as prime factor of 8

3: 1 time as prime factor of 6

The lowest common multiple is:

2 * 2 * 2 * 3 = 24

<u>The lowest height at which the two stacks will be the same height is 24 inches.</u>
