Perpendicular to y=4x-7; contains the point (4,3)
san4es73 [151]
Okay, so a general rule for finding perpendicular lines in the form of y = mx + b is y = (-1/m) + b.
First, let's ignore b (-7) because we're going to find that later.
A perpendicular line to y = 4x + b is y = -1/4x + b.
Alright, so now let's plug in the values. They are in the form of (x,y), so let's plug them in accordingly.

3 = -1/4(4) + b
3 = -1 + b
b = 4
y = -1/4x + 4
So a line perpendicular to y = 4x - 7 is y = -1/4x + 4.

Arlen has a recipe for lasagna that serves 8 people and uses 2 teaspoons of garlic. How many teaspoons of garlic will be used to
Y_Kistochka [10]
Your answer is A) 1 teaspoon.

The ratio for this problem is 8, 2, where 8 is the people, and 2 is the teaspoons. 4 people is half of 8 when you divide 8/4 so you have to do the same with the other part of the ratio. when you split 2 in half, you get 1 teaspoon as your answer

Hope this helps :)

Answer:

24

-560

Step-by-step explanation:

(1) (-2) * 3 * (-4)

A negative time a negative is a positive

2*3*4 = 24

(iv) 8 x 7*(-10)

This result will be negative since there are positive times negative

8*7 =56* 10 = 560

8*7* (-10) = -560
