What is another way to write the function f(x) = 5^x. The choices are
Kay [80]

Answer:

Correct answer is f(x) = (625^x)^1/4

Step-by-step explanation:

We know that

625 = 5^4

This means

f(x) = (625^x)^1/4

f(x) = (5^(4x))^1/4

But we know this is equivalent to

f(x) = (5^(4x*(1/4))) =

= 5^(x)

Correct answer is f(x) = (625^x)^1/4

Two lines intersect in a plane in form for angles what are the angles formed fathers intersect is a 53° angle what are the measu
DedPeter [7]

Answer:

53°, 127°, 127°

Step-by-step explanation:

<u>Two intersecting lines form two pairs of angles:</u>

  • Pair of vertical angles. They are opposite to each other and are equal
  • Pair of adjacent angles which are supplementary angles and their sum is  180°

<u>So if one of the angles is measured 53°, then the other angles are:</u>

  • 53°- vertical angle with the first one
  • 180° - 53° = 127°
  • 180° - 53° = 127°

Given y &lt; 4x – 6, explain how to graph this and decide whether or not (– 1, 5) is a solution to this inequality
svp [43]

the point (-1,5 ) is NOT a solution to the inequality.

There are three steps in graphing an inequality:

Rearrange the equation so "y" is on the left and everything else on the right.

Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)

Shade above the line for a "greater than" (y> or y≥)

or below the line for a "less than" (y< or y≤).

Now to solve this, graph the line y=4x-6

Lets use the point (0,0)

0<-6, is NOT true

So we shade everything to the left of the line y=4x-6

Hope that helped.
