Y= x + 3
1. Find the gradient(slope)
1 - 7 / - 2 - 4
=1
2. Find the y. Intercept ( c )
Y = x + c
Replace by any of the two coordinates given (4 , 7 )
7 = 4 + c
C= 3
Equation => Y = x + 3
Answer: Graph A
Step-by-step explanation: The line drops, crosses over the y axis, then stays at that constant level
Answer:
12*5%=0.6
Step-by-step explanation:
8+6=14-2=12
12*5%=0.6
Answer: y = 0.5cos(x), choice A
The parent function y = cos(x) follows this same basic pattern of the curve shown, but it starts off at (0,1) as its highest point. This graph has its highest point to be half as high, so we multiply by 1/2 or 0.5
Answer:
The answer is 118.
Step-by-step explanation:
First we need to subtract the meal cost from average unit cost for each meal:

A restaurant profits 1.25$ for each meal. If we divide fixed cost to profit for each meal:

The restaurant have to sell 118 meals at least each day for the owner to break even
