(10 points worth)

Answers

Answer:

x = 9

Step-by-step explanation:

First, subtract 9 from both sides, and you are left with 2x < 18. Then, divide 18 by 2 to get 9. I hope this helps :)

The value of x is 9.

To find x

2x+9≤27

Subtract 9 from both sides we get,

2x ≤18

Divide 2 from both sides,

x≤9.

Hence, the value of x is 9.

Solve the system of equations using substitution. y = -7x 2x – y = -9

Answers

Answer:

x = -1

y = 7

Step-by-step explanation:

We have a system of equations and are asked to solve using substitution.

y = -7x

2x - y = -9

Since we have an equation for y by itself, we can plug the first equation into the second.

2x - (-7x) = -9

Distribute :

(-(-7x))

2x + 7x = -9

Add like terms :

9x = -9

Divide 9 by both sides to get x :

x = -1

Now that we know x, we can plug it into the first equation to find y :

y = -7(-1)

y = 7

3x - 2y = 10

3x - 2(0 - x) = 10                  ( 2(0 - x) = -2x )

3x - (-2x) = 10                      ( y = -x )

3x + 2x = 10

The triangles below are similar. By what ratio was triangle XYZ enlarged by to create triangle LMN? Use this information to calculate the length of the missing side. Show your work.

Answers

Answer:

Ratio: 3:2

LN = 18

Step-by-step explanation:

"similar" means that all the angles are the same and the sides were all increased by the same proportion.

Thus, we know that MN/YZ = LM/XY = NL/ZX

First, we need to find the ratio. To do this, we write MN/YZ as a fraction, and simplify.

MN/YZ = 15/10 = 3/2

(If you want, you can double check this using LM nd XY. 8 * 3/2 = 12, so this is correct)

To find the missing side, we simply multiply XZ by 3/2.

12 * 3/2 = 18, so LN = 18.

visiting team scored 5 three-pointers,
8 two-pointers, and 5 free throws. Which
team scored more points?

Answers

Answer:

home team

.............................................................................................

If home team had 4 three-pointers, 10 two-pointers, and 6 free throws. The visiting team scored 5 three-pointers, 8 two-pointers, and 5 free throws. Then Home team scored more points.

What is Addition?

Addition is a process of combining two or more numbers.

For Home team,

4 three-pointers,

10 two-pointers, and

6 free throws

4+10+6

Four plus ten plus six

20

For visiting team

5 three-pointers,

8 two-pointers, and

5 free throws

5+8+5

Five plus eight plus five

18

As we observe 20 is greater than 18, so home team scored more than Visiting team.

Hence Home team scored more points.

How long will it take for $3000 to grow to $11,700 at an interest rate of 6.3% if the
interest is compounded continuously? Round the number of years to the nearest
hundredth.
A) 0.83
B) 2160.28
C) 21.60
D) 2.16

Answers

Answer:

Step-by-step explanation:

Using A=P(1+r/n)^nt

Where,

P = principal amount (the initial amount you borrow or deposit), in this case $3000

r = annual rate of interest (as a decimal), in this case 0.06

t = number of years the amount is deposited or borrowed for, in this case we don't know it

A = amount of money accumulated after n years, including interest, in this case $21000

n = number of times the interest is compounded per year, in this case 12

     This gives us 21,000=3,000(1+0.06/12)^12t

    After simplification, 7=(1.005)^12t

By taking the logarithm of both sides,

                            Log7=Log1.005^12t

                               12t = Log 7/Log 1.005

                               12t =390.1545

          This gives us 32.5months
