Step-by-step explanation:
what ? you cannot do even simplest subtractions ?
what is it you don't understand here ?
how such a function works ?
you take every value for x (the input variable or argument), put it in place of the "x" (this is nothing else than a placeholder for the actual values) and then perform the mathematical operations. y is then the result of that.
x = 0
y = 0 - 7 = -7
the ordered pair of (x, y) is (0, -7)
x = 1
y = 1 - 7 = -6
(1, -6)
x = -3
y = -3 - 7 = -10
(-3, -10)
x = -5
y = -5 - 7 = -12
(-5, -12)
Answer:
y= −9.16x²+73.04x+183.3
Values increase till x = 4 and then decrease which means thus curve has a maximum turning point around 4.
Coefficient of x² should be negative
because max to (concave down)
x = -b/2a should be around 4
x = -73.04/(2×-9.16) = 3.987
184 cubes difference
Explanation:
First guy made a 2x2x2 (L x W x H)
L: 2 x 2 = 4 ( twice as long)
W: 2 x 3 = 6 ( three times as wide)
H: 2 x 4 = 8 ( four times as high)
New block:
4 x 6 x 8 = 192
192 - 8 = 184 cubes different
The answer is b because you have 4 queens in a deck of cards and 13 clubs in a deck so if you add them you would get 17/52 cards
