Y=mx+c where m is the gradient.
If the equation is perpendicular is -
Use y-y1=m(x-x1)
and you should get
y+1=-
(x+4)
4y+4=-3x-12
y=-<span>
</span>x - 16
Step-by-step explanation:
Equation: y = (x - 1)² + 4
f(x) = 4x + 3
g(x) = -2x + 5
(f · g)(5) = (4(5) + 3)(-2(5) + 5)
(f · g)(5) = (20 + 3)(-10 + 5)
(f · g)(5) = (23)(-5)
(f · g)(5) = -115
Answer:
We are given that 4 lb of candies are bought for $9.00
Therefore, the price of 1 lb of candies is:
Now the amount of candies that can bought for $12.00 is:
lb
Therefore, 5.3333 lb of candies can be bought for $12.00
