Answer:
The area increases by 6 square units.
Step-by-step explanation:
The original area of triangle
A = 1/2 bh
a = 1/2 (4)*3
6 square units
Now we double the height
A = 1/2 (4) *6
A = 12 square units
The difference is 12-6 = 6 square units
3, - 3
To find the intercepts
let x = 0, in the equation for y- intercept and y = 0 for the x- intercept
x = 0 → - y = 3 ⇒ y = - 3 ⇒ (0, -3) is y- intercept
y = 0 → x = 3 ⇒ (3 , 0) is the x- intercept
that is 3, - 3
Answer: The equation is <em>s</em> = 350 + 60<em>s</em>, and given this equation, we can determine that the total savings after eleven weeks is $1,010.

We start at 62 Fahrenheit. And every hour we drop two degrees. We want to know how long it took for the temperature to drop to 40 Fahrenheit.
If one hour passed, then the temperature dropped two degrees.
If two hours passed, then the temperature dropped 4 degrees.
See the pattern? We can define this as 2h. Where h represents time in hours.
We subtract 2h from 62.
We can write this as a function. F(h) = 62 - 2h.
Where F is the temperature in Fahrenheit. And h is the hour(s).
Now that we have the formula, let's plug in the value 40 Fahrenheit to see how long it took for the temperature to drop to 40 degrees.
40 = 62 - 2h
Subtract 62 from each side
-22 = -2h
Divide both sides by 2
h = 11
So, it took 11 hours for the temperature to drop to 40 Fahrenheit.
