Answer:
The answer is 11/8 or 1 3/8
Step-by-step explanation:
First, you can break both fractions down into 3+1/4-1+7/8.
Second, use 3 subtract 1, you will get 2+1/4-7/8.
To subtract 7/8 you have to make both numbers denominator same.
1/4 will multiply by 2 on the top and the bottom.
After that, you will get 2 2/8-7/8.
2x8=16, 16+2=18
18/8-7/8=11/8 or 1 3/8
I know its gonna be confusing, but this is all I can do, sorry about that. :)
I not sure if you mean the gradient of the line or the equation, so here is both.
Gradient (=m) :
( 4, 4 ) ( 6, 5 )
( x1 , y1) ( x2, y2 )
m = y2-y1 / x2-x1
= -5-4 / 6 - 4
= -9 / 2 (as a fraction)
= -4.5 (as a decimal)
Equation of the line :
m = -9/2
( 4, 4 )
( a, b )
y - b =m (x - a)
y - 4= -9/2 (x - 4)
(Multiply both sides by 2 to get rid of fraction)
2y - 4 = -9 (x - 4)
2y - 4 = -9x + 36
2y = -9x + 36 + 4
2y = -9x + 40
2y + 9x = 40

Answer:
see below
Step-by-step explanation:
Each serving uses 1 green pepper and 1/3 red pepper, so for 9 servings Moira needs 9 green peppers and 9/3 = 3 red peppers.
Answer:
y = 240sin(180πx)
Step-by-step explanation:
This the answer because a is represented by the amplitude, 240, and the frequency is equal to IbI/2pi. to solve for b, multiply the frequency by 2pi.
