Answer:

View explanation.

Step-by-step explanation:

The question isn't clear on whether or not you are asking if the mom or if the store is owing money to the credit card company. The store owes the full amount paid. The mom owes nothing. You can look at the images for a more detailed explanation, but it is not really needed.

Komok [63]

Answer:

I think it would be x÷6-9 or x/6-9

Step-by-step explanation:

Quotient means to divide so you are dividing x by 6. Decreased by 9 means subtract by 9. I hope this helps you! :)

Error Analysis: Kayla said the remainder of x^3+ 2x^2 -4x + 6 divided by
andrezito [222]

9514 1404 393

Answer:

  C) No, Kayla is not correct, because the remainder is -49 not 149

Step-by-step explanation:

The remainder from division by x+5 can be found by evaluating the polynomial at x=-5, the value of x that makes the divisor zero.

Evaluation is often easier when the function is written in Horner form.

  ((x +2)x -4)x +6

For x=-5, this is ...

  ((-5 +2)(-5) -4)(-5) +6 = (-3(-5) -4)(-5) +6 = 11(-5) +6 = -49

Kayla is not correct; the remainder is -49.

Which of the following represents the graph of f(x) = one−half to the power of x?
puteri [66]

f(x) = \frac{1}{2}^x

In this exponential function , the base is \frac{1}{2}

if base is less than 1 then it a decreasing function

We can verify it using a table

We plug in some x and values and find out f(x) to get point for the graph

x -----> f(x)

-1 -----> 2

0 ------> 1

1 -------> 0.5

The table is same as the points in first graph.

So first graph represents the graph of f(x) = \frac{1}{2}^x

Veseljchak [2.6K]
W=2L

P=300=2(L+W)
so

300=2(L+W)
divide by 2
150=L+W

W=2L
subsitute

150=L+2L
150=3L
divide by 3
50=L
sub back

W=2L
W=2(50)
W=100

the field is 100yd wide by 50yd long
