Answer:
4,8
Step-by-step explanation:
because the lins equation goes through in 6
The variable is d, so the coefficient is 1/4. Factor out 1/4 and you are left with (d-3).
Answer:
36 objects
Step-by-step explanation:
You want the value of x when t=9, so you're solving ...
9 = 0.007x^2 +0.003x
9 = 0.007(x^2 + 3/7x)
From here, we observe that an approximation is probably sufficient.
9/0.007 = x(x +3/7) . . . . . the expression on the right is nearly x^2
x ≈ 3/√.007 ≈ 35.9 ≈ 36
We can check:
.007(36)(36 3/7) = 9.18
.007(35)(35 3/7) = 8.68
To keep the computer busy for 9 seconds, it needs to sort 36 objects.
The number of 8th grade students have dropped by 25% this year
The product of 4 and 7 would be 28!
When someone says the product of x means they are looking to multiply!
