Answer: (5, 12)
Step-by-step explanation:
Just graph the linear equations and find where they intersect.
Algebraically, you can set them equal to each other
-3x-3=2x+2
-x-3=2
-x=5
x=5
Plug x=5 to any equation
y=2(5)+2
y=12
Answer:
$11.03.
Step-by-step explanation:
5 % = 0.05.
The amount after 2 years
= 10(1 + 0.05)^2
= $11.03.
Let x be the rate per hour for Brown;
Then 2x is the rate per hour for Jones;
We have the equation: 375 = 5 * ( 2x ) + 5 * x ;
=> 375 = 10x + 5x;
=> 375 = 15x;
=> x = 375 ÷15;
=> x = 25mph ;
=> 2x = 50mph.
