Answer:
B
Step-by-step explanation:
When you divide each of the prices by the amount of candy bars, B is the lowest. The price for 1 candy bar with A's price is 1.75. The price for 1 candy bar for B's is 1.71. The price for 1 candy bar with C's is 1.73 and the price of 1 candy bar for D's is 1.74. Again, B has the lowest price for 1 candy bar so the correct answer is B.
This gives you three simultaneous equations:
6 = a + c
7 = 4a + c
1 = c
<u>c = 1
</u><u /><u />
If c =1,
6 = a + 1
<u>a = 5
</u><u /><u />
This doesn't work in the second equation, so the quadratic that goes through these points is not in the form y = ax^2 + bx + c
Was there supposed to be a b in the equation?
Answer:
126.4 cm
Step-by-step explanation:
1. 15.8 * 3 = 47.4 (This is the length)
2. Find half of the rectangle
47.4 + 15.8 (width) = 63.2
3. Find the whole perimeter
63.2 * 2 = 126.4
The answer is 90. you add them all up and divide it by 4
Answer:
y=4/3x+15 1/3 (or) y=4/3x+46/3
Step-by-step explanation:
If it’s parallel, it has to have the same slope (4/3).
Plug 7 in for x, and then find out what you have to do to make y equal -6.
y=4/3x+15 1/3 (or) y=4/3x+46/3
