Let a be the length of one side;
We have the formula P = 4 x a;
Then, 4 x a = 252 yards;
a = 252 / 4;
a = 63 yard;
Hey there!
Let's go through all of our options.
A) It's defintely not curved; it's written in slope intercept form and is indeed a straight line.
B) Yes, the graph is a straight line. Although it's at an angle, it has no curves or flaws, and is completely straight.
C) The graph is not vertical. It has a y intercept and slope and therefore isn't. That's because it has a rate of change, and it crosses the y axis at some point depending on the slope, or rise over run. Vertical lines really don't have that.
D) Yes, the graph is a function. This is because it does not have two x values for one y, and does not fail the straight line test, which states that you can place a straight line anywhere on the graph and it can only go through one point.
E) This is false. If we put in -5 as our input, we add 1 and get -4, which is a negative output. Your output here depends on the input you put in, and the sign usually remains considering it's +1.
F) This graph does not pass through the origin. This is because the origin has a point at 0,0 and since it's x+1, it would be 0,1 instead because your output is adding one to that 0.
Hope this helps!
Answer:
As x gets bigger, y is now getting smaller.
Step-by-step explanation:
A fancy way to say this is that the function y = 2-x is what we get when we reflect y = 2x across the y-axis.
Answer:
We should add 2.4 quarts of pure orange juice to 3.6 quarts 10% orange juice to make 6 quarts of 40% orange juice.
Explanation:
Let p represent number of quarts of pure orange juice and q represent number of quarts of 10% orange juice.
We have total quarts required = 6
So, p+q =6 --------------------equation 1
The orange content of 6 quarts = 40 % = 6 x 40/100 = 2.4 quarts.
Orange content in p pure juice = p quarts.
Orange content in q, 10% juice = q x 10/100 = 0.1 q quarts
So we have, p + 0.1 q = 2.4 --------------------equation 2
Equation 1 - Equation 2 gives
0.9 q = 6 -2.4
q = 3.6 quarts
p + 3.6 = 6
p = 2.4 quarts
So we should add 2.4 quarts of pure orange juice to 3.6 quarts 10% orange juice to make 6 quarts of 40% orange juice.
