The order pair that lies on the graph of h(x) = -2(x^2) is
(1, -2). By substituting the given ordered pair only (1, -2) will satisfy the
equation.
h(x) = -2(x^2)
-2 = -2(1^2)
-2= -2(1)
-2= -2
So the ordered pair lies on the graph is (1, -2)
Just take the function, and wherever it says 'x', substitute '-3' .
Then it'll say f(-3) = -2(-3)² - 7(-3) + 6 . Surely you can solve that.
As my old Electronic Circuits professor used to tell us, back around 1962:
"If
f(x) = -2x² - 7x + 6
then
f(cow) = -2cow² - 7cow + 6 ."
Of all the things I learned from him, this is the thing I remember most.
Answer:
4 1/12 sq. ft
Step-by-step explanation:
To know the amount of area that Pete’s bed have more than Fluffy’s bed, we simply calculate the area of both beds then subtract the smaller from the larger.
The area of Fluff’s bed would be 3 * 21/12 = 63/12 Sq ft
The area of Pete’s bed would be 4 * 28/12 = 112/12 sq ft
The difference in area is thus: 112/12 - 63/12 = 49/12 = 4 1/12 sq. ft
70 because 55+55 = 110 and a triangle is 180 so 180-110= 70 and X is opposite to the angle we worked out as the missing one
