Answer:

n=3

Step-by-step explanation:

14m-7n=7

14(2) - 7n = 7

       +7n    +7n

28 =  7 +7n

        -7   -7      

21 =7n

21/7 = 3

n=3

What is the area of the figure?<br><br> A. 126 in2<br> B. 240 in2<br> C. 282 in2<br> D. 360 in2
sweet [91]
Divide the figure into 2 rectangles. One being 12in x 13in and one being 18in x 7in. Find the area of each rectangle.
12in x 13in = 156in^2
18in x 7in = 126in^2
Add the two areas.
156 + 126 = 282in^2

282in^2 is the answer so (C)

Plutonium-240 decays according to the function Q(t)=Q(subscripto)e^(-kt) where Q represents the quantity remaining after t years
svetoff [14.1K]
<span>The answer is 9,990 years. Using the exponential decay question, we can figure out how long it will take Plutonium-240 to decay from 27 grams to 9 grams. Setting the equation up looks like this, 9 = 27 e^ (-0.00011 t). From this you get, 0.333333 = e ^(-0.00011 t). Next, you simplify by dividing both sides by the natural log, -1.0986 = -0.00011 t. Finally, you solve by dividing both sides by -0.00011, giving 9,987 years for t, rounded up to 9,990 years.</span>

Option 1: y = 5x+5 is the correct answer

Step-by-step explanation:

We can put the values of x in each option one by one and then compare the output to find the best option

So,

<u>For y = 5x+5:</u>

Putting x=1,2,3,4,5...

y = 5(0)+5 = 0+5 = 5\\y = 5(1) +5 = 5+5 = 10\\y = 5(2) + 5 = 10+5 = 15\\y = 5(3) + 5 = 15+5 = 20

The values of x in the function are producing the output values of y, which means that the function for values given in the table is defined by: y= 5x+5

Hence,

Option 1: y = 5x+5 is the correct answer
