Answer:
(-3, -2)
Step-by-step explanation:
To find the solution of two functions, you need to know at which x and y value they are equal. So solve for x and y when 1/3x - 1 = 2x + 4
1/3x - 1 = 2x + 4
First, subtract 2x from both sides.
-5/3x - 1 = 4
Add one to both sides.
-5/3x = 5
Multiply both sides by the reciprocal of -5/3 (3/-5)
x = -3
Then, substitute x into one of the equations to get y.
1/3(-3) - 1
-1 - 1 = -2
So drag the dot to the point (-3, -2)
Answer:
your numbers are -5 and 9, since 9 * -5 = -45 but 9 + (-5) = 9 - 5 = 4
Answer: 48 ounces in 3 pounds (16 ounces to a pound)
Answer:
f(3) = 42
Step-by-step explanation:
f(x) = 3x² + 5x
Then
f(3) = 3(3)² + 5(3)
= 3×9 + 5×3
= 27 + 15
= 42
