I might be wrong but 9
9*2=18
18+7= 25
25 square root = 5
Answer is 9
Answer:
Step-by-step explanation:
<u>Given</u>:
- d = 32 miles
- t = 2 1/3 hr = 7/3 hr
<u>Find the rate s:</u>
- s = d/t
- s = 32÷7/3 = 32 × 3/7 = 96/7 ≈ 13.7 mph (rounded)
Answer:
Step-by-step explanation:
Vertex form is accomplished by completing the square on the quadratic. Do this by first setting the parabola equal to 0 then moving the constant over to the other side:

Now take half the linear term, square it, and add it to both sides. Our linear term is 6. Half of 6 is 3, and 3 squared is 9:

The reason we do this is to create a perfect square binomial on the left:
(obviously the 0 results from the addition of 9 and -9). Move the 0 back over to the other side and set the quadratic back equal to y:

This gives you a vertex of (-3, 0), which is a minimum value, since the parabola opens upwards.
we have given an expression
.
we have given the value of x,y and m .
.
we need to find the value of expression mx-y.
we need to plug the respective values and solve.
