Answer:
x + x+12 + 3(x+12) = 123
x = 15
Step-by-step explanation:
Jamil : x
Kiera : x+12
Luther : 3 ( x+12)
x + x+12 + 3(x+12) = 123
Distribute
x + x+12 + 3x+36 = 123
Combine like terms
5x+ 48 = 123
Subtract 48 from each side
5x+48-48 = 123-48
5x =75
Divide by 5
5x/5 = 75/5
x = 15
What you want to first is substitute the numbers in for the variables in the equation
Since b= -5 , we will plug it in for -b
-5 + c = -13x
Now plug in -8 for c
-5 + (-8) = -13x
Add the numbers on the left side, which gives you -13.
-13 = -13x
Lastly, divide both sides by -13x, which will give you 1.
So x = 1
Answer:
The graph of a quadratic equation, or a parabola, looks like a U, an upside down U, a C, or a backwards C. We can use the following rules to determine what the graph of a given quadratic equation looks like. If y = ax2 + bx + c, and a is positive, then the graph of the equation is the shape of a U.
Step-by-step explanation:
bc
All but the first simplify to something rational.
This means
since this interval lies outside the support of the density function.
