We have to set up 2 equations:
A) x + y = 10 liters
B) .05x + .25y = 10 * .10
Multiply equation B) by -4
B) -.2x - y = -4 then add to equation A)
A) x + y = 10 liters
.8x = 6 liters
x = 7.5 liters of 5%
y = 2.5 liters of 25%
-(4 1/5)
5(4)+1 = 21
Thus the answer would be -21/5
Answer: System 1 has an infinite number of solutions and System II has no solutions.
Step-by-step explanation:
If we look at system 1, we see that if we multiply the first equation by 2 and subtract the y value so that its on the same side as x, the equations are the same. That means that no matter the x or y value, it will be a solution.
If we look at system 2, however, we see that if we multiply the top equation by 3, the equations are the exact same except for the fact that the top equation has a -21. This means that no matter the x or y, there will never be a solution.
Answer:
f(x) = -|5x|+3
Step-by-step explanation:
When doing transformations that go up or down, the number always goes all the way on the right, separate from the x. When its being translated up its positive, when its being translated down, its negative.
Answer:
<u><em>d</em></u>
Step-by-step explanation:
because if you. 5 x 2 x 4; 6 x 4 x 5=<u><em>equals your answer as the one up in the question </em></u>if you don't trust me use calculator.then you'll see which is 160.
