I believe the answer is the first one
The answer is 19.4047.
To find the answer, follow my instructions:
First, find the difference or subtract 21.23 and 2.04. You'll get 19.19.
Second, find the sum or add the numbers 1.115, 3.18, 22.0613, and 12.2384. Remember that when adding numbers that are decimals, you have to align all of the decimal points to get the right answer. The sum of all those numbers are 38.5947.
Third, gather your data. So you got the numbers 19.19, and 38.5947. The question is asking for the difference between them. Remember that difference means subtraction or subtracting/minus. So subtract those numbers. You'll get 19.4047.
I hope you find this answer the most helpful! :)
The answer to the question is x=-12.1hopes this helps you.
<span> Step 1: subtract X from both sides.
0.5x-6-x=x+0.05-x
-0.5x-6=0.05</span>
Step 2: Add 6 to both sides.
-0.5x-6+6=0.05+6
-0.5x=6.05
Step 3: Divide both sides by -0.5.−0.5x−0.5=6.05−0.5
The complete question is
"which statement is true about the extreme value the given quadratic equation? y = -3x^2 + 12x - 33
Oa. The equation has a maximum value with a y coordinate of -27
Ob. The equation has a minimum value with a y coordinate of -21
Oc. the equation has a minimum value with a y coordinate of -27
Od. The equation has a maximum value with a y coordinate of -21"
The quadratic equation has the extreme value at the vertex with a y-coordinate of -21. so, the correct option is D.
<h3>What is a quadratic equation?</h3>
A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
The given quadratic equation is
y=-3x^2+12x-33
x = -b/2a
For the given equation the vertex :
x = -12/2(-3) = 2
The value of y at x = 2 is:
y = -3(2²) + 12(2) - 33
y = -12 + 24 - 33
y = -21
The extreme is the maximum for the given equation.
The correct choice is D.
