Answer:
n = -7
Step-by-step explanation:
49 = -5n - 2n
combine like terms
-5 - 2 = -7
49 = -7n
divide both sides by -7
49/-7 = -7n/-7
49/-7 = n
49/-7 = -7
-7 = n
Check the picture below.
that's the line of x = 12, just a straight vertical line, notice the green line, that's parallel to it, and the red line, that's perpendicular to it.
let's pick two points for each to get their slopes, hmm say for the green one (5,2) and (5,4)
and for the red one hmmm (3,2) and (7,2)
Step-by-step explanation:
X intercept of -5 means the line cuts the x axis at -5 so, mark with a small dot/x at - 5 on the x axis which is the horizontal line
y intercept of 3 means the line cuts/passes thru the y axis at 3. so, mark it with a dot/cross at 3 on the vertical line
now, join the 2 markings together with a straight line
You must simplify
the expresision given, as it is shown below:
1. The exponents can be simplify if
they are divisible between index 4 of the root. So, let's decompose
the number 144:
144=(2˄4)(3˄2)
2. Now, you have to divide the exponents
between index 4.When you do this, you obtain:
[(144)(a˄12)(b˄3)]˄1/4
[(2˄4)(3˄2)(a˄12)(b˄3)]˄1/4
2a˄3[(3˄2)(b˄3)]˄1/4
2a˄3(9xb˄3)˄1/4
Then, the correct answer is the first
option: 2a˄3(9xb˄3)˄1/4
