Answer: x> y+2/5
Step-by-step explanation:
Answer:
27x +42+ 3x²
Step-by-step explanation:
so im learning this rn in class and what you do is FOIL
So its stands for
First
Outside
Inside
Last
(3x+6)(x+7)
(3x+6)(x+7) -- 3x² (if you have x times x it is x to the second power)
(3x+6)(x+7) -- 21x
(3x+6)(x+7) -- 6x
(3x+6)(x+7) -- 42
Now add 21x and 6x
27x +42+ 3x²
you must have added the 21 and 6 incorrectly.
Answer:
3rd option
Step-by-step explanation:
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
y = - 2(x - 4)² + 3 ← is in vertex form
with vertex = (4, 3 )
• if a > 0 then vertex is minimum
• if a < 0 then vertex is maximum
here a = - 2 < 0
then vertex (4, 3 ) : maximum
The suit case originally weights 48 kg
.75x = 36x = 33/ .75 = 48
