Is the ordered pair
FrozenT [24]

Answer:

no, because for x=-3, y would have to be -31

Step-by-step explanation:

boy oh boy (or girl oh girl) - you wrote this in a horrible, horrible format.

I can only guess what your problem and the fitting answer would be.

y = -2×x^2 + 3×x - 4

-4 = -2×(-3)^2 + 3×(-3) - 4

-4 = -2×9 - 9 - 4

-4 = -18 - 9 - 4

-4 = -31

and that is wrong. for (-3,-4) to be on the graph of the function, y would have to be -4 when using x=-3 in the function. but y = -31 for x= -3.

Reduce 720/1080 little cunfused
Veronika [31]
To reduce a fraction, divide the numerator and the denominator equally until they reach the simplest whole number possible. 

In this case, the numerator (720) and the denominator (1080) can both be divided by 360 to get 2/3, our reduced fraction.

a window is shaped like a parallelogram. the height of the window is half the length of the base of the window. the base of the
rusak2 [61]

The area of the parallelogram is 36 inches square.

We have a parallelogram shaped window whose dimensions are as follows-

base (b) : 12 inches

height (h) : \frac{1}{2} \times 12 = 6 inches

Other side = 10 inches

We have to find the area of the window.

<h3>What is the formula to calculate the area of a parallelogram of given base (b) and height (h).</h3>

The area of the parallelogram is given by -

A = \frac{1}{2} \times base\times height

In the question given - We can apply the above formula to estimate the area of the window.

A = \frac{1}{2} \times 12\times6 = 36 inches square.

Hence, the area of the parallelogram is 36 inches square.

PLEASE HELP ASAP Arrange the expressions in increasing order of their values.
dybincka [34]
For this case we have the following expressions:
 (10⁰x 10¹ x 1¹⁰)
 (10 x 10¹)
 (10⁰ + 10¹ + 1¹⁰)
 (10⁰ + 10¹x 1¹⁰)
 Rewrite we have:
 (1x 10 x 1) = 10
 (10 x 10) = 100
 (1 + 10 + 1) = 12
 (1 + 10x 1) = 11
 Answer:
 
In increasing order we have:
 
(10⁰x 10¹ x 1¹⁰)
 
(10⁰ + 10¹x 1¹⁰)
 
(10⁰ + 10¹ + 1¹⁰)
 
(10 x 10¹)
