I think its c but im not sure
Answer:
f(x)= (x+8)^2 + 200
Step-by-step explanation:
-b/2a gives you the x coordinate of the vertex and then plug it in for x to get the y coordinate. Put it in the formula (f()x= (x-h)^2 +k).
H is the x coordinate and K is the y coordinate
Answer:
Total number chocolate bars with almonds sold were approximately 66.34 and total number chocolate bars with walnuts sold were approximately 34.67.
Step-by-step explanation:
Let number chocolate bars with almonds be x
Also let number chocolate bars with walnuts be y
Given:
Number of chocolate bars with almonds that were sold one weekend was 3 less than 2 times the number of chocolate bars with walnuts.
Framing the above sentence in equation form we get;

Also given:
The number of chocolate bars with walnuts plus 4 times the number of chocolate bars with almonds was 300.
Framing the above sentence in equation form we get;

Now Substituting the value of x in above equation we get;

Now we will substitute the value of y in equation
we get;

Hence, Total number chocolate bars with almonds sold were approximately 66.34 and total number chocolate bars with walnuts sold were approximately 34.67.
Answer:
Step-by-step explanation:
<u>Midpoint of JK:</u>
- x = (-12 + 8)/2 = -4/2 = -2
- y = (3 - 5)/2 = -2/2 = -1
<u>Slope of the line JK:</u>
- m = (-5 - 3)/(8 - (-12)) = -8/20 = -2/5
Perpendicular lines have negative reciprocal slopes.
So the line r has a slope 5/2 and passes through the point (-2, -1)
<u>Equation of r:</u>
- y = 5/2x + b
- -1 = 5/2(-2) + b
- -1 = -5 + b
- b = 5 - 1
- b = 4
<u>So the equation is:</u>
The expression that represents the volume would be: <span>C) 6x^3+39x^2+54x</span>
Proof of the calculation:
V = Lwh
V = (x+2) (3x) (2x+9)
V= (3x^2 + 6x) (2x + 9)
V = (6x^3 + 27X^2 +12x^2 + 54x)
V = 6x^3 + 39x^2 + 54x
