B. Barbara's equation did not consider the number of bottles of iced tea. She only put 1.49, which would mean she only sold one. Because we know she sells more then one, it should be 1.49(then a variable)
These are a lot easier when they r like this...no coefficient in front of ur x^2.
x^2 + 5x - 14....u see ur last sign, the -.....this tells me that in ur 2 factors, both signs will be different....one is positive and one is negative. U see ur first sign, the +, this tells me that ur bigger number will be positive.
Now we just have to find 2 numbers, that when added = 5 and when multiplied = 14, So ur 2 numbers are 7 and 2.
(x^2 + 5x - 14) =
(x + 7)(x - 2) <===
Answer: 360 - 44 - 80 = 236
236 ÷ 2 = 118
both angle equal to 118
Step-by-step explanation:
Answer:
The first number is 10 and a he second number is 7.
Step-by-step explanation:
Small number= 7
Big number= 7*2=14-4
=10
Answer:
1. -2+2x=y
Step-by-step explanation:
You only need to try the first two lines of the table to determine which equation works.
Only equations 1 and 4 work for the first line of the table (x=0).
- 1. -2 +2·0 = -2 . . . . . . . this works
- 2. 2 -2·0 = 2 ≠ -2
- 3. 2 +2·0 = 2 ≠ -2
- 4. -2 +0 = -2 . . . . . . . this works
Of those, only equation 1 works for the second line of the table (x=1).
- 1. -2 +2·1 = 0 . . . . . . . this works
- 4. -2 +1 = -1 ≠ 0
The equation that is true for the table values is ...
-2 +2x = y
