Answer:
Step-by-step explanation:
(x-7)^2
(x-7) ( x-7)
-14x + 49
it's a perfect square function
Answer:
speed = distance/time
= 400/267
= 1.49
1.5
i hope this is right lol good luck
Answer:
a x sqrt(7) - 49sqrt(x)
Step-by-step explanation:
sqrt(7x) [ sqrt(x) - 7sqrt(7)]
Distribute
sqrt(7x) *sqrt(x) - sqrt(7x)*7sqrt(7)
We know that sqrt(a) sqrt(b)= sqrt(ab)
sqrt(7x^2) - 7sqrt(7^2 *x)
Now lets separate out the perfect squares
sqrt(7) *sqrt(x^2) - 7sqrt(7^2)*sqrt(x)
x sqrt(7) - 7*7sqrt(x)
x sqrt(7) - 49sqrt(x)
Answer:
7 8/21, 7.6, 7 2/3, 7.71, 7 4/5
Step-by-step explanation:
none
Answer:
y≥1/2 x +1
Step-by-step explanation:
first the line in the graph is bold and not dotted
so the sign is either ≤ or≥
the shaded area is on the top , on this case it is greater than
the right answer is y≥1/2 x +1
