We need to complete the statement that " A number raised to a negative exponent is ___ negative"

Consider a number 'a' raised to a negative exponent say '-m'.

a^{-m}

According to the law of exponents.

We get, a^{-m}=\frac{1}{a^{m}}

Now let us consider two cases:

Case 1 : If 'a' is a positive number, let a = 'x'.

Then, a^{-m}=x^{-m=}\frac{1}{x^{m}} which is positive.

Case 2: If 'a' is a negative number, let a= '-x '

Then, a^{-m}=(-x)^{-m=}\frac{1}{-x^{m}} which is negative.

Therefore, we can say that

" A number raised to a negative exponent is sometimes negative".

Valentin [98]

Answer:

Part A: 7n + 30= -5 and 8n + 40= 16

Part B: 7(8) + 30= 86 and 8(8) + 40= 104

Part C: Company A saves you 12.

Step-by-step explanation:

Company A: 7n + 30

Company B: 8n + 40

7n + 30= -5       8n + 40= 16

7(8) +30= 86     8(8) +40= 104

7(2) + 30= 44    8(2) + 40= 56

56 - 44= 12

Write an equation of the line that passes through (1, −1) and is perpendicular to the line y=1/2x−3. An equation of the perpendi
lapo4ka [179]
Y = 1/2x - 3. Slope here is 1/2. A perpendicular line will have a negative reciprocal slope. All that means is flip the slope and change the sign. So the perpendicular line will have a slope of -2.

y = mx + b
slope(m) = -2
(1,-1)...x = 1 and y = -1
now we sub and find b, the y int
-1 = -2(1) + b
-1 = -2 + b
-1 + 2 = b
1 = b

so ur perpendicular equation is : y = -2x + 1

-4w+18w+2=10-6w <br><br> What is w?
kiruha [24]

Answer:

w = .5

Step-by-step explanation:

-4w + 18w+2=10 -6w

14w + 2 -2 = 10 -2 -6w

14w + 2w = 8 - 2w + 2w

16w = 8

16w/16 = 8/16

w = .5
