Answer:

-4(-7/30)-3/5=1/3  

4(-1/15)+3/5=1/3

Step-by-step explanation:

1. -4x-3/5=1/3

-4x=1/3+3/5

-4x=14/15 <- divide both sides

x= -7/30

2. 4x+3/5=1/3

4x=1/3-3/5

4x= -4/15 <-divide both sides

x= -1/15

Sandy is driving cross country. She has covered 200 miles from the east coast towards the west coast. She has driven this distan
lilavasa [31]

Okay so here it is

the answer is M=100D + 200

Why?

because 200miles divided by 2 days is 100 so every day she drives 100 miles which means you would times the days by 100 miles and since you have already gone 200 miles it would be

m=100d+ 200

hope this helps

Write an equation of the circle with center (-6, 2) and diameter 10.
marshall27 [118]

Solution:

We know that the formula to write the equation of a circle is (x – h)² + (y – k)² = r², where h is the x coordinate, k is the y-coordinate, r is the radius of circle, and the center of circle is (-6,2).

<u>Finding the radius of the circle.</u>

  • Diameter: 10 units
  • Radius: 10/2 units = 5 units

<u>Creating the equation:</u>

  • (x – h)² + (y – k)² = r²
  • => (x + 6)² + (y – 2)² = 5²

The equation is (x + 6)² + (y – 2)² = 5².

Simplify the rational expression.  State any restrictions on the variable.
AveGali [126]

Answer:

The last choice.

Step-by-step explanation:

\dfrac{k^2-k-2}{k^2-4k-5}=\dfrac{(k+1)(k-2)}{(k+1)(k-5)}=\dfrac{k-2}{k-5}

The value of k must be restricted from being one that makes the original denominator zero. Hence k ≠ -1 or 5.
