Solve for v.
19v – 18 = 16 + 17v

Answers

Answer 1

Answer:

v= 17

Step-by-step explanation:

Start with the given equation.

19v – 18 = 16 + 17v

Move -18 to the other side, and swap it's sign.

19v = 16 + 18 + 17v

Move 17v to the other side and swap it's sign.

19v - 17v = 16 + 18

Combine like terms.

2v = 34

Divide by 2v.

v = 17

Answer 2

Answer:

v = 17

Step-by-step explanation:

Given

19v - 18 = 16 + 17v ( subtract 17v from both sides )

2v - 18 = 16 ( add 18 to both sides )

2v = 34 ( divide both sides by 2 )

v = 17

which describes a number that cannot be irrational?

Answers

Answer:

A number that can be written as the ratio of two integers .

Step-by-step explanation:

Irrational numbers are numbers those numbers that have infinite non-periodic decimals, that are reproduced in an unlimited way without an end point, without any part of the sequence being repeated. The set of irrational numbers, added to the rational numbers, configures the category of real numbers.

Irrational numbers include, for example, the famous number Phi (π), whose approximate value is 3.14 ..., extending its decimals indefinitely. These numbers are most often used in mathematical analysis.

In 1970, the median home value was $20,000. By 2020, the median home value was $320,000. What is the percent increase in home value in those 50 years?

Answers

Answer:

1500%

Step-by-step explanation:

The formula for Percentage increase is

Increase/ Initial Amount × 100

Increase = Current Amount - Initial Amount

Increase = $320,000 - $20,000

Increase = $300,000

Percentage Increase =

$300,000/$20,000 × 100

= 1500%

The percent increase in home value in those 50 years is 1500%

Answers

Answer:

309.12

Step-by-step explanation:

A = total amount

P = principal

r = interest rate

n = number of times interest is compounded

t = time (in years

A = P(1 + [tex]\frac{r}{n}[/tex])^nt

A = 300(1 + [tex]\frac{.03}{12}[/tex])^12 · 1

PLEASE HELP! DUE TOMORROW 1-8-21 !! Look at these equations. Write each equation in slope-intercept form. Are these equations the same or different? Explain. I don’t know how to do the middle equation so please show work for that.

Answers

Answer:

y = 2x-4

all the equations are the same as the slope-intercept form is the same for all the equations

Step-by-step explanation:

slope-intercept form:

[tex]y = mx + b[/tex]

2x-3 = y+1

i) move y to the left-hand side and change its sign

-y+2x-3 = 1

ii) move 2x-3 to the right-hand side and change its sign

-y = 1-2x+3

iii) add the numbers

-y = (1+3)-2x

-y = 4-2x

iv) change the signs on both sides of the equation

y = -4+2x

v) use the commutative property to reorder the terms

( commutative property: the number on which we operate can be moved or swapped from their position without making any difference to the answers )

How to graph 2x + y = 4 ?
Explain steps please !!

Answers

you need to rearrange your equation to make y the subject which would be

y= -2x+4

this now matches the formula y= mx+c , -2 being m and 4 being c.

c is your y intercept so the graph will go through 4 on the y axis. Then m is the gradient of your graph and because it is negative you know it is going downwards. 2 means that every unit value you go across the x axis the y axis will go down 2.

To find where your graph crosses the x axis you need to make y=0 in your equation which looks like
0=-2x+4
2x=4
x=2

Now you know that your x intercept is 2 so you can draw a line going through 4 on the y axis and 2 on the x axis like my photo.

11. If 9m - 3 = -318, then 14m = ?
a. -28
b. -504
c. -329
d. -584
e. -490

Answers

Answer:

e. -490

Step-by-step explanation:

-318+3= -315

-315/9= -35

So that would mean m= -35

-35*14= -490

9m - 3 = -318
+ 3. + 3
9m. = -315
9m / 9 = -315/9
m = -35

14m =
14 (-35) = -490

The answer is e

Solve for x:
5(x + 1) - 8 = 5x(2 - 4)
A)
-5
B)
5
D)

Answers

Answer:

x should equal three

Step-by-step explanation:

5(x + 1) - 8 = 5x(2 - 4)

5x+1-8=5x-4

5x-7=5x-4

+7 +7

5x= 5x +3

÷ 5 ÷5

×=3

5(x + 1) - 8 = 5x(2-4)
5x + 5 - 8 = 10x - 20x
5x - 3 = -10x
= 5x - 5x - 3 = -10x - 5x
= -3 = -15x
= -3/-15 = -15x/-15
= 0.2 = X
So, in conclusion, X is equal to 0.2

Isabella deposited $2,000 in an account that earns 5% simple annual interest. After one year, how much interest will her investment earns?

Answers

Answer:

2100

Step-by-step explanation:

5% of 2000 = 2000 x 1/20 = 100.

2000+100=2100

Also, if it said how much interest will her investment PAY, then it would be $100 because of the 5% simple interest.

Ans = $2,100
2000 x 1.05= 2100
1.00 = 100%
1.05 = 100% +5%
