Answer:
f(7) - f(-7)
= (4 - 7^2) - ((-7)^3 - 2*(-7))
= -45 - (-329)
= 284
Answer:
I don't think I can remember every skill I was taught through the years but in Kindergarten we used Number Sense so we could understand the meaning of more and less also there's estimation and PEMDAS. I've also learned how to round up so that the solution is at least around those numbers if the skill is to be applied.
hope that helps
Step-by-step explanation:
Answer:
Apples = 24
Pears = 40
Step-by-step explanation:
Let u be the unit of fruit in the basket,
number of apples: 
number of pears: 
now to find u, we equate the two equations.

Now simplify.



Now we can find the original number of apples and pears by substituting u.
so original number of apples = 
and original number of pears = 
Answer:
$0.06 per square inch
Step-by-step explanation:
The question should be:
<em>"If tile costs $8.50 per square foot, how much does it cost per square inch?"</em>
<em />
To solve this, we basically need a conversion from feet to inches. BUT 2 times, since we are talking about "square feet" and "square inches".
We know 1 feet = 12 inches
Also, since we are going from square feet to square inches [big to small], we have to divide TWICE.
Thus, we will have:

We are dividing 8.5 (the cost) by 12, 2 times since we want square feet in square inches. The answer is:

So, tile costs $0.06 per square inch
Here, Take any two coordinates: (0, 1) & (4, -2)
Slope, m = y2 - y1 / x2 - x1
m = 1 - (-2) / 0 - 4
m = 3/-4
m = -3/4
In short, Your Answer would be Option D
Hope this helps!
