Find the y-intercept of each line defined below and compare their values

Answers

Answer:

They are 8 units apart, and the y-intercept of line A is above the x-axis by 6 units, and line B is below the x-axis by 2 units

Step-by-step explanation:

Remember your y-intercept has an x value of zero, so line B has a y intercept of (0,-2)

now let's find b in the original equation so

y - 8 = -2x - 2 so y = -2x -2 + 8, so y = -2x + 6

So line A has a y-intercept of (0,6)

They are 8 units apart, and the y-intercept of line A is above the x-axis by 6 units, and line B is below the x-axis by 2 units

Ramon earns $1,725 each month and pays $53.70 on electricity. To the nearest tenth of a percent, what percent of Ramon's earnings are spent on electricity each month?

Answers

Answer:

Step-by-step explanation:

Remark

The formula you use is (Electricity / Total Income ) * 100

The ratio becomes 53.7/1725  * 100%

The ratio is 53.7/1725 * 100 = 0.03113 * 100

The % = 0.03113 * 100 = 3.113

To the closest tenth that is 3.1%

Joanne deposits $4,300 into a one-year CD at a rate of 2.3%, compounded daily.
What is her ending balance after the year?
How much interest does she earn?
What is her annual percentage yield to the nearest hundredth of a percent?

Answers

Answer:

5k

Step-by-step explanation:

The interest accrued on the principal is $100.

Using the formula;

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

A - amount

P - Principal

r = rate

n = Number of times the interest is compound

t = time in years

Substituting values;

A = 4,300( 1 + 0.023/365)365 × 1

A =  $4400

Interest =  $4400 - $4,300 = $100

The annual percentage yield is obtained from;

APY=100 (1 + r/n )n – 1

APY=100 (1 + 0.023/365)^n - 1

APY= 100(0.023)

APY= 2.3 %

So Maria is faster.

The polygons are similar, but not necessarily drawn to scale. Find the value of x.

Answers

16/12 = (x-1)/6
x-1 = 4/3 . 6
x = 24/3 + 1 = 9

32/24 = (y+1)/21
y+1 = 4/3 . 21
y = 84/3 - 1 = 25

The value of x is given from proportion and x = 9

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the first polygon and second polygon be similar

So , the ratio of their corresponding sides will also be similar

Substituting the values in the equation , we get

( x -1 ) / 6 = 16 / 12   be equation (1)

On simplifying the equation , we get

Multiply by 6 on both sides of the equation , we get

( x - 1 ) = ( 16 x 6 ) / 12

( x - 1 ) = 16 / 2

On simplifying the equation , we get

x - 1 = 8

Adding 1 on both sides of the equation , we get

x = 9

And ,

( y + 1 ) / 21 = 32 / 24   be equation (2)

On simplifying the equation , we get

Multiply by 21 on both sides of the equation , we get

( y + 1 ) = ( 4 x 21 ) / 3

y + 1 = 4 x 7

y + 1 = 28

Subtracting 1 on both sides of the equation , we get

y = 27

Hence , the value of x is 9
