Answer:
The answer is C
Step-by-step explanation:
Multiply all of the values by 2 and then you end up with the bigger triangle.
10 times (3*4)
You have to multiply 10 with both of the numbers in parenthesis
So, 10*3=30 and 10*4=40
30+40=70
Does this look right for the first one
Just substitute in values into the equation corresponding to the x,y:
To solve for a missing y value, substitute the corresponding x value, so 0, 2.33, and 6.25.
To solve for x, set the equation equal to the x and solve.
x's:
0
.25
2.33
4.5
6.25
y's:
5
5.75
14.99
18.5
23.75

By scenario, you could make that equation 3x + 5 the rental time of a very cheap carper cleaner service. They charge 5 dollars as the static fee, and 3 dollars per hour
The given equation is -3x²+240x-800
The maximum of the function is given when
where a and b are the constant of a quadratic form ax²+bx+c
We then have
a = -3
b = 240
Substitute these values into the maximum/minimum formula we have
Which means that the maximum profit is obtained when the number of refrigerators produced is 40 items a day
The maximum profit is
p = -3(40)²+240(40)-800 = $4000
B is equal to 1/5. Hope I was able to help
