Answer:
They show as intersections with the x-axis
Step-by-step explanation:
For example, the quadratic y = x² - 1 has roots x = -1 and x = 1.
They show on the graph as intersections of the parabola with the x axis at x = -1 and x = 1.
The total amount of the resulting mixture can be calculated by adding up the volume of the given substances assuming that volume addition is applicable given the properties of the fluids used.
That is,
T = 6 quarts + 10 quarts = 16 quarts
The total volume of the resulting mixture is 16.
Then, we do the component (antifreeze) balance by adding up the resulting antifreeze from the substances to the total. We let x be the percentage of antifreeze in the final mixture.
6(0.52) + 10(0.32) = 16(x)
The value of x from the equation is 0.395.
Therefore, the answer to this item is 39.5%.
Answer: y ≤ -x + 2
<u>Step-by-step explanation:</u>
There are an infinite number of possible solutions.
Plot the two points, draw any line between them such that the two points are NOT connected, then choose the inequality symbol that shades (-1, 3).
Here is one solution that satisfies the requirements. y ≤ -x + 2
Here is another: y < -x + 3
And another: y > x + 3
And one more: y ≥ x + 4
Answer:
The answer is A
Step-by-step explanation:
Down 2 right 3. You can figure this out for other problems like this by choosing any point on the graph and following the slope. It's down because the 2 is negative and 3 is positive to it goes to the right.
If you want to increase something by 31% then...
100%+31%=131% or 1.31
you multiply it by 131% or 1.31. So for 429 grams...
429*1.31=561.99grams
If you increase 429 by 31%, you get 561.99 grams
Answer=561.99 grams
