No because if you multiply a positive times a negative you will just get a negative and 7 isn't an negative so no.

In order to figure this out, you must solve the equation.

1-6x=7 (given)

-6x=6 (subtract 1 from both sides)

X=-1 (divide both sides by -6)

The answer is no.

What is the longest line segment that can be drawn in a right rectangular prism that is 15 cm long,

Romashka [77]

Assuming you want to find the length of the longest line segment, you would have to first determine where the longest line segment is.

If you can't do this straight away, then it'd be good to draw a diagram as I shown below, to visualise.

From there, you apply pythagora's theorem to the dimensions of the rectangular prism to find the length of the longest line segment.

I have attached the solution in a photo, including some explanation. Hope it helps :)

1.What is (2,-1) translated up 3 units 2.(5,2) translated down 4 and left 1

natka813 [3]

Answer:

1. (2,2)

2. (4,-2)

Step-by-step explanation:

Up and Down would refer to the Y coordinate while Left and Right would refer to the x coordinate. With this information we can determine that -1 up three units is 2 as -1 + 3=2, 5 left one unit is 4 and two down 4 is -2

Luke earned $36,000 during the first year of his job at Putt-Putt Kingdom. After each year he received a 10% raise. Find his tot

Lady_Fox [76]

In order to solve this problem, you need to use a geometric series:
$S_{n} = \frac{ a_{1}(1 - r^{n}) }{1 - r}$
where:
a₁ = first term of the series = 36000
r = common rate = 10% raise, therefore 1.10
n = number of terms = 5

Therefore,
 $S_{n} = \frac{ 36000(1 - 1.10^{5}) }{1 - 1.10}$
= 219783.60 $

Luke's total earnings in five years are 219783.60 $.
