Is (2,10) a solution of the equation y = 9x

<h3><u>No.</u></h3>

This line is already in slope-intercept form.

The slope of the line is 9, and the y-intercept is 0.

Because of this, we can find every y value for any x value simply by replacing x with the value of the x coordinate.

By replacing x with 2, we can see what the y coordinate would be when x is 2.

9(2) = 18

The y value would be 18, which is not 10, meaning (2, 10) is not a solution to the equation.

Combine like terms.
coldgirl [10]

Answer:

To solve the question the answer is 35y2 - 5 (i think)

Step-by-step explanation:

Yes and it's actually very simple.

To start off:

Simplify the equation: multiply 7 by the numbers in the parentheses getting: 28y2 - 35 .......full equation: 7y2 + (28y2 - 35)

New equation: 7y2 + (28y2 - 35) now combine like terms this means adding each common variable together. in this case, 7y2 and 28y2 would be added together to simplify the equation. Add them together, the new equation is: 35y2 - 5

Lmk if you have any questions i hope this helps

Step-by-step explanation:

Perimeter=2l+2w

l=w+6

Perimeter=2(w+6)+2w

44=2w+12+2w

44=4w+12

32=4w

8=w

l=8+6

l=14

area=lw

area=14x8

area=112 ft square

avanturin [10]

Answer:

At least 13 chocolates must be removed

Step-by-step explanation:

If there are three flavors, the probability of drawing 1 would be: 1

1/3 = 0.333

Which means, that every 3 attempts, theoretically you should do 1 of each, but how they ask for 5 chocolates of each would be:

3 * 5 = 15

At least 15 chocolates must be extracted to theoretically guarantee 5 chocolates each, but how we are interested in knowing is that a single flavor has 5 chocolates, so we discard the last two chocolates that represent the other two flavors

Therefore, for there to be safely 5 chocolates of the same flavor, at least 13 chocolates must be removed.
