The perpendicular slope is the negative reciprocal of the slope of the line it is perpendicular to. Therefore, the slope would be the negative reciprocal of -1/2 which would be 2.
From there, you plug in the coordinate into x and y and solve for b;
5 = 2 * -3 + b
5 = -6 + b
b = 11
Therefore the equation is;
y = 2x + 11
Answer:
D
Step-by-step explanation:
f(x) * g(x)= (3x^2-4x-5)(11x-3)
33x^3-44x^2-55x-9x^2+12x+15
33x^3-53x^2-43x+15
Answer:A 16-ounce can of mixed nuts includes 6 ounces of cashews and 10 ounces of almonds. What is the ratio of almonds to mixed nuts in this can of nuts?
Step-by-step explanation:
Answer:
Price after discount = 2.4 (1-.3)
Price after discount = 2.4 (.7)
Step-by-step explanation:
We know the cost after the discount.
Price after discount = original price - original price * discount rate
Factoring out the original price
Price after discount = original price (1- discount rate)
We know the discount rate = .3 and the original price is 2.4
Price after discount = 2.4 (1-.3)
Price after discount = 2.4 (.7)
Price after discount = 1.68
