It's called "solve the equation for 'y' ". That means move things
around so that you end up with 'y' all alone on one side, and
everything else on the other side.
You started with 9x - 7y = -7
Subtract 9x from each side: - 7y = -9x - 7
Divide each side by -7 : y = 9/7 x + 1
-6
2y = 3y + 2
-3y
-y = 2 so y = -2
Answer:
The goat population reaches 1000 in 12.4 years
Step-by-step explanation:
After <em>t </em>years, the number of goats is given by
where 
is the initial number of goats and <em>b</em> is the per capita growth rate.
From the question,
- <em>b</em> = 0.5
- <em>N</em> = 1000
If 10 oranges cost 4.70, then the price of one orange must be 4.70:10
4.70:10=0.47
FINAL ANSWER—0.47
Answer:
2.75cm
Step-by-step explanation:
Given data
Area of circle= 23.79cm^2
We know that the formula for the area of a circle is
Area= πr^2
Substitute
23.79=3.142*r^2
23.79/3.142= r^2
7.57=r^2
Square roo both sides
r= √7.57
r= 2.75 cm
Hence the radius is 2.75cm
