7+(-15)+12
Adding a negative number is the same as simply subtracting it.
7-15+12
7 - 15 = negative 8 (use a number line)
-8 + 12 = 4 (use a number line)

Answer:

a = -4.

Step-by-step explanation:

25(√5)^a * (√5) ^3 = 5√5

25*5^a/2 * 5^3/2 = 5*5^1/2

25*5^a/2 = 5*5^1/2 / 5^3/2

25*5^a/2 = 5^1 *5^1/2 / 5^3/2

25*5^a/2 = 5^3/2 / 5^3/2 = 1

5^a/2 = 1/25 = 5^-2

The bases are equal, so

a/2 = -2

a = -4.

Consider the graph of the linear function h(x) = –6 + h(x) equals negative 6 plus StartFraction 2 Over 3 EndFraction x. x. Which

kifflom [539]

The quadrant that the graph will not go through is the second quadrant.

The reason is that the slope is positive and there was a translation 6 units down

<h3>How to know the quadrant the graph will not pass</h3>

The quadrants are named in anticlockwise direction starting from the first which has x - positive and y - positive

The graph of y = 2x/3 is a graph with positive slope, moving through the third and first quadrant.

y = 2x/3 - 6 means a translation 6 units down and this pushed the line to get to the fourth quadrant

Hence the remaining quadrant that is untouched is the second quadrant

The graph is attached
