Answer: 17/50
Step-by-step explanation:
First, to add fractions, we must find a common denominator, in this case, 100.
Then, we must make the fractions being added all have the common denominator.
So, we must multiply 3/10 * 10/10, which equals 30/100
30/100 + 4/100
Then, just add across the numerator to get 34/100, which can be simplified to 17/50
<h3><u>The value of x, the first number, is equal to 3.</u></h3><h3><u>The value of y, the second number, is equal to 7.</u></h3>
x + 3y = 24
5x + 3y = 36
We can subtract both equations from each-other to cancel out a variable.
After doing so, we're left with:
-4x = -12
Multiply each term by -1
4x = 12
Divide both sides by 4.
x = 3
Now that we have a value for x, we can solve for y.
Plug this value into the first equation.
3 + 3y = 24
Subtract 3 from both sides.
3y = 21
Divide both sides by 3.
y = 7
Answer:
Step-by-step explanation:
If this is an exponential function, it is of the form
where x and y are coordinates from your table, a is the intial value, and b is the growth/decay rate. To find out what the equation is that represents this data, choose 2 points and solve first for a and then for b. Just a hint: If at all possible, choose the coordinate that gives you an x of 0. You'll see why in a minute.
I chose the first 2 points from your table: (0, .2) and (1, .8). Solving first for a:
The reason to choose the x of 0 as one of your points is because anything raised to the power of 0 is 1. So our equation then becomes:
so
a = .2 Easy enough.
Now use that value along with the other coordinate to solve for b:
b to the first is just b, so,
.8 = .2b
Divide both sides by .2 and you'll get that
b = 4
The equation, then, is
which is growth, since the value for b is greater than 1.
