7 * 38 + 3*45 - 56
use order of operations
(7*38) + (3*45) - 56
266 + 135 - 56
=345
the answer is C (0,0) because thats the only choice that is in the blue shaded area on the graph
you can also test it by plugging in 0 into the equation and your answer will be true meaning that (0,0) is a correct answer
Answer:
x={7,3}
Step-by-step explanation:
x^2-2x+9+12=0
x^2-2x+21=0
(x-7)(x-3)=0
x-7=0
x=7
x-3=0
x=3
so
x={7,4}
So,
Reggie has enough flour to last for 40 days.
Increasing his use of flour by 25% will reduce how many days of flour he will have by 25%, leaving him with 75% of the original number of days of flour left. We can do simple multiplication to find our result.

If Reggie increases his use of flour by 25%, he will have 30 days' worth of flour.
