Answer:
The 147th letter will be c.
Step-by-step explanation:
When you divide 147 by 4, if the remainder is 0, it's d, if it's 1, it's a, if it's 2, it's b, and if it's 3, it's c.
B is correct because when you plug in x=0 into the equation, you get 5.
This means that the y intercept is five.
Here's why the other answer choices are wrong:
The graph is actually INCREASING.
x can be NEGATIVE.
Not all exponential graphs has a y intercept of ONE.
Have an awesome day!
The answer is
6X - 4 = 12 + 2X
The current area is 15 x 9 = 135 square feet.
He wants to increase both the length and width by X:
Set up an equation:
(15 +x) * (9 +x) = 135 * 2
Simplify :
x^2 + 24x + 135 = 270
Subtract 270 from both sides:
x^2 + 24x - 135 = 0
Use the quadratic formula to solve for x:
-24 +/- √(24^2 - 4(1*-135) / 2*1
x = 4.7 or -28.7
The answer has to be a positive value, so x = 4.7 feet.
