Answer:
The numbers are 12 and 36
Step-by-step explanation:
x + y = 48
x - y = 24
Add y to both sides of the equation
x = 24 + y
Substitute new value for x into first equation
24 + y + y = 48
Add y's together
24 + 2y = 48
Subtract 24 from both sides of the equation
2y = 24
Divide both sides of the equation by 2
y = 12
48 - 12 = 36
The numbers are 12 and 36
Hope this helps :)
There are three different choices for the American.
There are 16 different choices for the first non-American and 15 different choices for the other non-American.
So, there are 3 x 16 x 15 different groups.
But, order is important -- who gets the gold, who gets the silver, and who gets the bronze -- there are 6 different ways to arrange the 3 winners (3! = 6).
Thus, there are 6 x 3 x 16 x 15 different results.
Y = 16x^2 + 36
Lets find the intercepts, making x and y to zero and solving:
<span>0 = 16x^2 + 36
</span><span>16x^2 = -36
</span>therefore there is not x-intercept, that is, when y equals zero the function does not have a value, is not defined.
Now, the y intercept, that is when x equals zero:
<span>y = 16x^2 + 36
</span><span>y = 16(0)^2 + 36
</span>y = 36
so, when x = 0, y = 36, that is, the function hits the y axis when x = 0

Step-by-step explanation:
The solution of a linear system is the intersection of the lines.
We can see the lines A and B intersect at the point (7.5, 12) which is the solution.

Answer:
y = x
Step-by-step explanation:
y = mx + b
m = slope, b = y - intercept
y = 1x + 0
y = x
