Evaluate the expression (4x^3)^2 for x=2 <br><br> A.128<br> B.512<br> C.256<br> D. 1024
julsineya [31]

Answer:

d:) 1024

Step-by-step explanation:

Evaluate (4 x^3)^2 where x = 2:

(4 x^3)^2 = (4×2^3)^2

Multiply each exponent in 4×2^3 by 2:

4^2 (2^3)^2

Multiply exponents. (2^3)^2 = 2^(3×2):

2^(3×2)×4^2

4^2 = 16:

2^(3×2)×16

3×2 = 6:

2^6×16

2^6 = (2^3)^2 = (2×2^2)^2:

(2×2^2)^2 16

2^2 = 4:

(2×4)^2 16

2×4 = 8:

8^2×16

8^2 = 64:

64×16

What is the equation of the line passing through the points (-25, 50) and (25, 50) in slope-intercept form?
babunello [35]

Answer:

Y = 50x

Step-by-step explanation:

Remember that slope intercept form is Y = mx + b indicating that m is the slope

To solve this equation use the formula

Y2 - y1 , x2 - x1:

50 - (- 50) = 100

25 - (-25) = 50

100/50 = 50/1

So the answer is y = 50x
