3. 140 is percent, I think is 1 2/5
4. 2.75 is decimal, 275 as percent
5. 0.08 is decimal, I think is 16/25
Given the exponential function y = f(x), a is the initial value and it will fall to a value of B
<h3>What is an
exponential function?</h3>
An exponential function is given by:
y = abˣ
Where a is the initial value of y and b is the multiplication factor.
The value, y, of a car x years after it is purchased is modeled by the exponential function y = f(x), a is the initial value and it will fall to a value of B

Answer:
t=10
Step-by-step explanation:
3*(t+4)-2*(2*t+3)-(-4)=0
Step by step solution :
Step 1 :
Equation at the end of step 1 :
((3 • (t + 4)) - 2 • (2t + 3)) - -4 = 0
Step 2 :
Equation at the end of step 2 :
(3 • (t + 4) - 2 • (2t + 3)) - -4 = 0
Step 3 :
Equation at the end of step 3 :
10 - t = 0
Step 4 :
Solving a Single Variable Equation :
4.1 Solve : -t+10 = 0
Subtract 10 from both sides of the equation :
-t = -10
Multiply both sides of the equation by (-1) : t = 10
Answers and Step-by-step explanations
13. Square both sides: x^2 + 4x + 4 = 16(x - 2) = 16x - 32
Move all the terms to one side: x^2 - 12x + 36 = 0
Factorize: (x - 6)^2 = 0 ⇒ x = 6
14. Move one of the roots to one side:
Square both sides: 2x - 1 = 3x - 12
Solve for x: x = 11
15. Subtract 4 from both sides: x - 4 =
Square both sides: x^2 - 8x + 16 = 4(x - 4) = 4x - 16
Move all the terms to one side: x^2 - 12x + 32 = 0
Factorize: (x - 4)(x - 8) = 0 ⇒ x = 4 or x = 8
16. Square both sides: x^2 - 4x + 4 = 9x - 36
Move all the terms to one side: x^2 - 13x + 40 = 0
Factorize: (x - 5)(x - 8) = 0 ⇒ x = 5 or x = 8
