1)Parallel means they have to have the same slope. Since our equation is y=2/3x+1, a line parallel to that would be(using out points) -5=2/3(-4)+b.
To find the y-intercept, solve for "b".
b=-7/3
Our equation would then be y=2/3x-7/3
2)Perpendicular lines have opposite-reciprocal slopes. our previous equation was y=2/3x+1, so our new equation would be -5=-3/2(-4)+b. Now lets solve for b.
b=-11
So our perpendicular equation would be y=-3/2x-11

Answer:
50 cents
Step-by-step explanation:
Let's set up a system of equations. Let x be a cookie and y be a brownie then...
x+2y=2x+y
x+y=1
We can solve this using substitution
x=1-y
1-y+2y=2(1-y)+y
1+y=2-2y+y
1+y=2-y
-1=-2y
y=1/2
One brownie costs 50 cents and one cookie costs...
x+1/2=1
x=1/2
One cookie costs 50 cents
5, and -5 because a negative times a negative equals a positive
Answer:
7.94
Step-by-step explanation:

The functions f(x), g(x) and h(x) are all linear functions
- The function value that is largest is h(-100)
- The function value that is largest is h(-100)
- The function value that is largest is f(1/100)
<h3>How to determine the function with the largest values</h3>
The functions are given as:



At x = 100, we have:



Hence, the function value that is largest is f(100)
At x = -100, we have:



Hence, the function value that is largest is h(-100)
At x = 1/100, we have:



Hence, the function value that is largest is f(1/100)
