belka [17]3 years ago
5 0

Answer:

No

Step-by-step explanation:

y = 2x -1

Substitute the point into the equation

4 = 2(3) -1

4 = 6-1

4 =5

This is not a true statement so the point is not on the line

Which of the following is a factor of 64x^3 +343
Lyrx [107]

Answer:

(4x + 7) or

(16x^2 - 28x + 49)

Step-by-step explanation:

This is the sum of cubes. If you have choices you really should list them because often the way  we write  answers is not in agreement with what you are given.

Step One

Factor 64x^3  and 343 into prime factors.

64x^3: 4*4*4*x * x *x

343: 7 * 7 * 7

Step Two

Factor using the sum of cubes.

(4x + 7)([4x]^2 - 7*4x + 7^2)

(4x + 7)(16x^2 - 28x + 49)

Cindy is buying a new car and wants to learn how the value of her car will change over time. Insurance actuaries predict the fut
lawyer [7]

Answer:

C=10000(0.852)^t

Step-by-step explanation:

Let the exponential function be,

C=a(b)^t

Here, C = cost of the car

t = Duration or period in years

From the given table,

Two points representing cost of the car and time are (10000, 0) and (8520, 1),

For (10000, 0),

10000=a(b)^0

a = 10000

For (8520, 1)

8520 = 10000(b)^1

b=\frac{8520}{10000}

b = 0.8520

Therefore, exponential equation will be,

C=10000(0.852)^t
