Answer:

A. Judy made a mistake between Steps 1 and 2.

She did not factor x² – 16=0 correctly.

x² – 16=0 is factored as:

(x +4) (x-4) = 0

Therefore, x = -4 and x = 4

Matthew biked for 4 days across an island. He started at the shoreline, which is at an elevation of 0 feet. At the end of day 1,
erica [24]

Answer:

The answer is 5,030 feet.

Step-by-step explanation:

It is stated that his starting point is at an elevation of 0 feet. He climbs 3.200 feet on the first day and then adds another 1.830 feet on the second day. This makes his total elevation 3,200 + 1,830 = 5.030 feet.

As he reaches the other side of the island on the 3rd day which is at an elevation of 0 feet as well, he loses all the elevation he gained on days 1 and 2, which is 5,030 feet.

I hope this answer helps.

Ax+ay+xa+ya <br> Differentiate
Dmitry_Shevchenko [17]

Answer:

2 a

Step-by-step explanation:

Possible derivation:

d/dx(2 a x + 2 a y)

Differentiate the sum term by term and factor out constants:

= 2 a (d/dx(x)) + d/dx(2 a y)

The derivative of x is 1:

= d/dx(2 a y) + 1 2 a

The derivative of 2 a y is zero:

= 2 a + 0

Simplify the expression:

Answer:  2 a
