This equation can be solved graphically by plotting the equations
f(x) = 3^x
and
g(x) = 5x-1.
The x-coordinate of the point(s) of intersection is the solution.
_____
On my graphing calculator, I find it easier to locate x-intercepts, so I would rewrite the equation as
3^x -(5x -1) = 0
and plot the function
h(x) = 3^x -(5x -1)
The x-intercept(s) would be the solutions. (There are two: x≈0.577, x=2.)
Answer:
hope this helps!
Step-by-step explanation:
The formula for compound interest is P(1 + r)^t, where P = Principal (initial amount), r = rate (percentage rate), and t = time (years). Let's start off by adding 1 to the percentage rate in decimal form. 1.5% is 0.015 in decimal form. 1 + 0.015 is 1.015. The amount of time is 2 years, so we raise that decimal to the 2nd power. 1.015^2 is 1.030225. Do not delete this decimal from the calculator. Now, let's multiply it by the principal, which is 12,000 British pounds. When you multiply that decimal by 12,000, you get 12,362.70. There. Mary's investment will be a value of £12,362.70
15x = -75 Divide both sides by 15.
Final answer: -5

<em>PQR = 150°</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>PQR = PQS + SQR</em>
<em>12x - 6 = 16 + 9x + 17</em>
<em>12x - 9x = 16 + 17 + 6</em>
<em>3x = 39</em>
<em>x = 13</em>
<em>PQR = (12×13 - 6)° = (156 - 6)° = 150°</em>
<em>Good luck !</em>
Answer:
The value of MX is 5.5 units.
Step-by-step explanation:
As the complete question is not given, the complete question is found online and is attached herewith
brainly.com/question/11944039
The diagram is attached with the solution.
As the line ZM is dividing the angle in two parts thus as the two angles are equal thus
The sides are given as
XZ=11
YM=3.5
YZ=7
Now by the theorem of the angles, the bisected angles are such that sin(<YZM)=sin(<XZM)
so

So the value of MX is 5.5 units.
