Answer:
the dryer costs $425
Step-by-step explanation:
x = washer
y = dryer
x + y = 803
x = y - 47
using the second equation a substitute in the first equation we get
y - 47 + y = 803
2y = 850
y = $425
FYI
x = y - 47 = 425 - 47 = $378
11/12 has a greater value than 5/6
Y=-1x-3
Slope always is the x value and then just plug it in and add or subtract accordingly
F(x) = x² increases at a faster rate than g(x) = 2x.
f(x)
Reason:
x = 0, 1, 2, 3, 4, 5, 6, 7
f(x) = 0, 1, 4, 9, 16, 25, 36, 49
g(x) = 0, 2, 4, 6, 8, 10, 12, 14.
Comparing the values of f(x) and g(x), we can see that that of f(x) are far higher than that of g(x) for the same values of x.
So f(x) increases at a faster rate.

Step-by-step explanation:
3x^2 + 5x - 12
To solve it, you need an equation, so I think you mean this equation.
3x^2 + 5x - 12 = 0
Using the quadratic formula, you have a = 3, b = 5, c = -12.
