Answer:
See explanation!
Step-by-step explanation:
We know that the maximum miles allowed before oil change is 5,000miles (<u>thus Kaci can drive less or up to 5,000 miles but not more</u>).
Kaci has already driven 3,450miles since last oil change.
Inequalities are typically employed to show a relating or comparative relationship between expressions and can be identified by the sybolism of less, more or/and equal to (i.e. 
, 
, 
, 
).
Let us denote the miles Kaci can drive before oil changing again by 
, then we can write the following inequality:
solving for the remaining miles allowed
Thus Kaci can drive up to and including 1550 miles before chaging car oil again.
Answer:
a is 2x+2x and 4x
b is 6(7y-4) and 6*7y-6*4
We write the equation in terms of dy/dx,
<span>y'(x)=sqrt (2y(x)+18)</span>
dy/dx = sqrt(2y + 18)
dy/dx = sqrt(2) ( sqrt(y + 9))
Separating the variables in the equation, we will have:
<span>1/sqrt(y + 9) dy= sqrt(2) dx </span>
Integrating both sides, we will obtain
<span>2sqrt(y+9) = x(sqrt(2)) + c </span>
<span>where c is a constant and can be determined by using the boundary condition given </span>
<span>y(5)=9 : x = 5, y = 9
</span><span>sqrt(9+9) = 5/sqrt(2) + C </span>
<span>C = sqrt(18) - 5/sqrt(2) = sqrt(2) / 2</span>
Substituting to the original equation,
sqrt(y+9) = x/sqrt(2) + sqrt(2) / 2
<span>sqrt(y+9) = (2x + 2) / 2sqrt(2)
</span>
Squaring both sides, we will obtain,
<span>y + 9 = ((2x+2)^2) / 8</span>
y = ((2x+2)^2) / 8 - 9
The mixed number is 1 and 7/8 because 15 minus 8 equals 7/8 and since you went over the whole (8/8) it is 1 plus 7/8 which equals 1 and 7/8.
It's okay that you might not be good in math that's why we will help.
