Whats the best way to do this operation?---------------------------------Phillip charged $400 worth of goods on his credit card. On his first
bill, he was not charged any interest, and he made a payment of $20. He
then charged another $18 worth of goods. On his second bill a month
later, he was charged 2% interest on his entire unpaid balance. How much
interest was Phillip charged on his second bill?

Answers

Answer 1

Answer: $400 - $20 = $380 ( The original charge subtract the amount he paid. )
$380 + $18 = $398 (The amount unpaid plus another charge equal total amount unpaid.)
$398 x 0.02 = $7.96 (The amount unpaid multiply the percentage of interest = amount of interest.)

Phillip charged $7.96 interest on his second bill.

what is the rate of change for the linear relationship modeled in the table? x y −1 10 1 9 3 8 5 7 -1/2 0 1/2 2

Answers

Answer:

Rate of change for the linear relationship modeled is $(-1)/(2)$

Step-by-step explanation:

As the there is a linear relationship in the points, so all these points will be on a single straight line. Hence the slope will be same throughout all the points.

We know that, the slope of the line joining (x₁, y₁) and (x₂, y₂) is,

$m=(y_2-y_1)/(x_2-x_1)$

Putting the points as (-1, 10) and (1, 9), we get

$m=(9-10)/(1-(-1))$

$=(9-10)/(1+1)$

$=(-1)/(2)$

Rate of change is the slope of the line joining all these points.

(-1,10)(1,9)
slope = (9 - 10) / (1 - (-1)
slope = -1/2 <=== slope is also ur rate of change

What are the approximate solutions of 2x2 + 9x = 8 to the nearest hundredth?a. x ≈ 1.22 and x ≈ 3.28
b. x ≈ −0.76 and x ≈ 5.26
c. x ≈ −1.22 and x ≈ −3.28
d. x ≈ −5.26 and x ≈ 0.76

Answers

Answer:

The roots of the equations are x ≈ -5.26 and x ≈ 0.76 .

Option (d) is correct.

Step-by-step explanation:

Formula for the roots is given by .

$x = \frac{-b \pm \sqrt{b^(2) -4ac}}{2a}$

As the equation in the form

$2x^(2) + 9x - 8 = 0$

As the equation in the form ax² + bx + c = 0

a = 2, b= 9 , c = -8

Put in the formula

$x = \frac{-9 \pm \sqrt{9^(2) -4* 2* -8}}{2* 2}$

$x = (-9 \pm √(81 + 64))/(4)$

$x = (-9 \pm √(145))/(4)$

$√(145) = 12.04$

Thus First roots be

$x = (-9 - 12.04)/(4)$

$x = (-21.04)/(4)$

x ≈ -5.26

The second root be

$x = (-9 + 12.04)/(4)$

$x = (3.04)/(4)$

x ≈ 0.76

Therefore the roots of the equations are x ≈ -5.26 and x ≈ 0.76 .

Option (d) is correct.

C. How many years apart were they born?My answers was as followed and it was wrongA.-75B.-69C.6

Answers

The years apart that they were born is 282

How to express their years as a negative number?

Archimedes' birth year

We have the year range to be:

(287-212 B.C)

In the above years, the year of birth is:

287

As a negative number, we have;

-(-287)

Hence, Archimedes'birth as a negative number is -(-287)

Pythagoras' birth year

We have the year range to be:

(569-500 BC).

In the above years, the year of birth is:

569

As a negative number, we have;

-(-569)

Hence, Pythagoras 'birth as a negative number is -(-287)

The years apart that they were born

This is the difference between their birth years.

So, we have:

Years = -(-569) - -(-287)

Evaluate

Years = 282

Hence, the years apart that they were born is 282

Archimedes (287-212 B.C) --> - 287 birth year

Pythagoras (569-500 BC) ---> - 569 birth year

569 - 287 = 282 as years apart of their birth years
