The answer is B (6,4)..... if you put 6 for x and 4 for y in 2x-2y=4 you will confirm i am right
Answer:
(x-8y)(x-8y)
Step-by-step explanation:
write the expression as a product with the factors x and 8y
8^2 -2(x)8y+64y^2
multiply terms with equal exponents by multiplying the bases
x^2 -2 (x) 8y + (8y)^2
factor
(x-8y)^2 which is equal to c
Answer:92.4
Step-by-step explanation:
4x+7x=132
10x=132
x=132/10
x=13.2
4x=4×13.2
=52.8
5x=7×13.2
=92.4
Answer:
Total cooking time = 20t + 15
The expression 15t + 20 is wrong.
Step-by-step explanation:
weight of chicken = t lbs
cook time per lb = 20 minutes
This means that:
1 lb weight requires a cooking time of 20 minutes
1 lb = 20 minutes
∴ t lbs = 20 × t = 20t minutes.
We were also told that each chicken required an extra cooking time of 15 minutes, in addition to the total cooking time due to the weight. Therefore, the total cooking time is calculated thus:
Total cooking time = cooking time due to weight + 15 minutes
Total cooking time = 20t + 15
Hence the expression 15t + 20 is wrong, due to the explanation given above.
slope = (y2-y1)/(x2-x1)
the first slope is 0 (horizontal line)
second slope is undefined (vertical line)
