11. y = -23x - 21
You can get this by starting with y = mx + b (slope intercept form). Then put in all the knowns and solve for the b.
2 = -23(-1) + b
2 = 23 + b
-21 = b
Then add that to the end of the equation with m = -23
12. -5
The y-intercept of an equation is always the number added on at the end of an equation. It is also the number with no x attached to it.
13. 8x^9y^6
When you use the law of exponents, you need to make sure the exponent goes to each individual term. When we cube the 2, it becomes 8. When you cube x^3, you get x^3*x^3*x^3 or x^9. And with y^2 you get y^6
The answer is 18
2 to the 3rd power would be 2*2*2 which is 8
8 x 4=32
32/2=16
16+2=18
Answer:
Step-by-step explanation:
Given
Balloon velocity is 14 ft/s upwards
Distance between balloon and cyclist is 140 ft
Velocity of motor cycle is 88 ft/s
After 10 sec
motorcyclist traveled a distance of 
Distance traveled by balloon in 10 s

net height of balloon from ground =140+140=280 ft[/tex]
at 
distance between cyclist and balloon is 

now suppose at any time t motorcyclist cover a distance of x m and balloon is at a height of h m
thus 
differentiating w.r.t time





Answer:
The circumference is the outside perimeter of a circle. It's the distance around a circle. A radius can be a line from any point on the circumference to the center of the circle. If you put two radii together, edge to edge, going through the center of a circle, you would get a diameter.
