Answer:
2 1/2 or 2.5
Step-by-step explanation:
1/2x +4=9
-4 -4
1/2x= 5
/1/2 /1/2
x= 2 1/2 or 2.5
Answer:
50.6
Step-by-step explanation:
it says 7 students traveled by car so you need to take 7 from 311, then divide your answer (304) by 6, which is 50.6
Answer:
Step-by-step explanation:
The standard equation for a circle is given by:
Where (h, k) is the center and r is the radius.
We know that the center is (-4, 8). So, substitute -4 for h and 8 for k:
Simplify:
Now, we will need to find r.
We know that it passes through the point (-2, -1). So, we can substitute -2 for x and -1 for y and solve for r. So:
Evaluate:
Square:
Add:
So, r squared is 85.
We don’t actually have to solve for r itself, since we will have to square it anyways.
So, we have:
Substituting 85 for r squared, we get:
And we have our equation.
Answer: Choice B. The degree of the function is even, so the ends of the graph continue in the same direction. Because the leading coefficient is negative, the left side of the graph continues down the coordinate plane and the right side also continues downward.
That's a long winded way of saying "both ends go down together". That's how I think about it anyway.
The degree of the polynomial is the largest exponent, which in this case is 4. This is an even number so the ends either go up together or go down together. The leading coefficient being negative (specifically -1) indicates the ends go down together. I recommend looking at a graph or a table of values to see why this is the answer.
Answer:
13.4 miles,
Step-by-step explanation:
Day 1: 21.1 miles
Day 2: 13.5 miles
Day 3: 13.4 miles
How I got this answer is bc I added day 1 and day 2, then i subtracted 50 from it and got 13.4
hope this helps!!
