9 and 3 fourths is 9 3/4
3 and 3 eights is 3 3/8
So now you have to compare
9 3/4= 3 3/8 days
Y= 1 day
Y represents the unknown rate
Change the mixed fractions to improper fractions
4 times 9 plus 3=39/4
8 times 3 plus 3= 27/3
39/4= 27/3 days
Y= 1 day
Cross multiply
27/3 x Y=39/4 x 1
27/3 Y=39/4
Divide both sides by 27/3
39/4 ÷ 27/3
39/4 x 3/27
The answer is 13/12 miles which is 1.083 miles
Hope I helped. Good luck
Set y1=x+30 and y2=x^2, plugged those into the distance formula assuming x=a<span>,
</span><span>
d=rad(<span>(y2−y1<span>)^2)
</span></span></span><span>d(x)=x^2−x−30
</span>All you have to do is to maximize the given quadratic function. I hope that this is the answer that you were looking for and it has helped you.
Positive because two negative signs would make it a positive. The answer would be 7. If you had a positive 3 and a negative 4 it would make it negative (bigger number) If you had a positive 4 and a negative 3, it would be positive (bigger number yet again)
If I'm wrong I'm sorry XD I haven't gone this in years.
Answer:
(0, -6)
Step-by-step explanation:
Given the following systems of linear equations;
3x - 2y = 12 ...... equation 1
16x - 4y = 24 ........ equation 2
We would solve for the solution using the elimination method;
Multiplying eqn 1 by 2, we have;
2 * (3x - 2y = 12)
6x - 4y = 24
16x - 4y = 24
Subtracting the two equations, we have;
(6x - 16x) + (-4y -[-4y]) = (24 - 24)
-10x - 0 = 0
-10x = 0
x = -0/10 = 0
Next, we would find the value of y;
3x - 2y = 12
3(0) - 2y = 12
0 - 2y = 12
-2y = 12
y = -12/2
y = -6
Check:
3x - 2y = 12
3(0) - 2(-6) = 12
0 - (-12) = 12
12 = 12
