Step-by-step explanation:
The formula for the area of a circle is π*r^2, r being the radius or the half line in the circle, and the formula for the circumference is π*r*2, or π*d, or the diameter which is the line that goes all the way through like number 5. The radius is half the diameter.
Answer:
10x + 3
Step-by-step explanation:
3(2x + 1) + 4x =
= 6x + 3 + 4x
= 10x + 3
Answer:
y=2x-2
y=3x+1
Step-by-step explanation:
To solve this I will be using the point slope formula
It is as follows
y-y₁=m(x-x₁)
We can choose any m value so I will be choosing m=2
(x₁,y₁) will be (-3,-8) respectively because all we want is for the line to pass through that point
so we have
y-(-8)=2(x-(-3)
We can simplify this to
y+8=2(x+3)
y+8=2x+6
y=2x-2
We then repeat this process but choose a new m (the m value doesn't really matter as long as it's not 0)
I will choose 3
so we have
y-(-8)=3(x-(-3))
Which gives u
y+8=3(x+3)
y+8=3x+9
y=3x+1
Its value is 400.
Hope this helps.
