1. You have the following quadratic equation and to solve it, you must follow the steps below:
<span>
x</span>²<span>+3=9x
2. The form of the equation that you need to apply the quadratic formula, is:
ax</span>²+bx+c=0
<span>
3. Then:
</span>
x²<span>+3=9x
</span> x²-9x<span>+3=0
</span><span>
4. The quadratic formula is shown below:
x=(-b±√(b^2-4ac))/2a
5. Then, you have:
a=1
b=-9
c=3
6. When you substitute the values into the quadratic formula, you obtain:
x1=0.34
x2=8.65</span>
Answer:
4
Step-by-step explanation:
3^x=81 (the exponential form of the problem) and x would = 4
Julian is wrong because you need to multiply the 2 numbers you cannot add them. so the common denominator would be 20 not 9
Answer:
-2x -1 if f(x) is reflected along the x axis and translated 1 unit downward
Step-by-step explanation:
A function can either be reflected along the x axis or along the y axis. If a function is reflected along the x axis, the new reflected equation g(x) is given by:
g(x) = -f(x) = -2x
g(x) = -2x
If a function is reflected along the y axis, the new reflected equation g(x) is given by:
g(x) = f(-x) = 2(-x)
g(x) = -2x
Translation means the shifting of the curve either up or down in a graph. If the reflected function is shifted 1 unit upward, the function becomes:
g(x) + 1 = -2x + 1
If the reflected function is shifted 1 unit downward, the function becomes:
g(x) - 1 = -2x - 1
