Answer:

6\sqrt{-1}-7

Step-by-step explanation:

simplyifying this we get

1+5i-8+i

= 6i-7

I am assuming the i you are talking about here is the sqrt of negative one so that would be 6\sqrt{-1}-7

So the problem ask to calculate and covert the said equation or expression to the form of ca^pb^q where as all of the variables is a number. So base in that information and following some formula, the answer would be a^(-3/2)b. I hope you are satisfied with my answer

The equation 6y = 30 - 8x has solutions of (b, 1) and (a, b).<br> What are the values of a and b?
victus00 [196]

The values of a and b are a = \frac{3}{2} and b = 3, respectively.

In this question we need to solve the linear equation for each point, first for (x,y) = (b, 1) and later for (x,y) = (a, b).

If we know that (x,y) = (b, 1), then the value of b is:

6 = 30-8\cdot b

8\cdot b = 24

b = 3

If we know that (x,y) = (a, b) and b = 3, then the value of a is:

6\cdot b = 30 - 8\cdot a

18 = 30-8\cdot a

12 = 8\cdot a

a = \frac{3}{2}

The values of a and b are a = \frac{3}{2} and b = 3, respectively.

Please help!!! I am so confused!
Dafna11 [192]
The first one is c because if you put it at negative 1/8 then it is 0-1/8 or 1/8 away from zero

second one is
the reciprocal is the number that when multiiplied by the number you are trying to find the reciprocal of, you get +1 so the number you have is  2/7 so
2/7 times x=+1
multiply both sdies by 7/2 to clear fraction
x=+7/2
the reciprocal is +7/2 or +3 and 1/2 which is D
