Answer:

The value of f(x) at x=6 is  f(6) = 218

Therefore, the correct option is <u>D) 218</u>

Step-by-step explanation:

We need to solve the value of f(x) at x=6

Given step function is f(x)=6x^{2}+2 for the range of  -6 < x < 9

( 6 is in this range)

Substitute the value x=6 in f(x)=6x^{2}+2 :

f(x) = 6x^{2} + 2

f(6) = 6(6)^{2} + 2

f(6) = 6\times 36+ 2

f(6) = 216+ 2

f(6) = 218

Hence, the value of f(x) at x=6 is  f(6) = 218

Therefore, the correct option is <u>D) 218</u>

After trying to do it the hard way, i remembered the easy way.

substitution:

because x = 6 and 6 is in the range of -6 < x < 9, we only need the equation 6x^(2) + 2

f(x) = 6x^(2) + 2
f(6) = 6(6)^(2) + 2
f(6) = 6(36) + 2
f(6) = 216 + 2
f(6) = 218

Answer:

s,q,r

Step-by-step explanation:

r is bigger than q and s is q-2 so s is smaller than q therefore smaller than r so r is the biggest then q then s but since it’s asking for it in ascending order u go from smallest to biggest.

Kristin poured 6 ounces of lemonade into each of 19 glasses. Exactly how many ounces of lemonade did Kristin pour into all these
andriy [413]

Answer:

114

Step-by-step explanation:

If Kristin poured it in 19 cups and your figuring out how many in total, you’d have to multiply. I did an area model, to solve this, and 10 x 6 = 60, 9 x 6 = 54. Then we add 60 + 54 and get 114 as our answer. (I calculated so I’m sure I’m correct)

Solve for x: x - 5y = -1
Fantom [35]

Answer:

x = -1 + 5y

Step-by-step explanation:

If you writing this equation in terms of x then the answer is correct, however, if there is a value for y, then you just need to sub it into y.

For example,

Find x when y = 3

x = -1 + 5(3)

  = -1 + 15

  = 14

What is 2y+x=-6 and y=-2x+0 using substitution method?
vazorg [7]
2y + x = -6
y = -2x + 0

We can substitute the second equation into the first one.

2y + x = -6
2(-2x + 0) + x = -6
-4x + x = -6
-3x = -6

Divide -3 on both sides.

x = 2

Now, plug x = 2 into any equation and solve for y.

y = -2x + 0
y = -2(2) + 0
y = -4

The solution to the system of equations is (2,-4).

Richard rolls a fair dice 72 times.
Strike441 [17]

Answer:

24

Step-by-step explanation:

there are six sides of a dice, numbered one through six. 5 and 6 are greater than four, so there is a 2/6 chance that you will roll a number greater than 4, or 1/3. multiply 72 times 1/3 and that equals 24. 24 out of the 72 (24/72 = 1/3)times is how much you could expect to get a number greater than 4.
