Mathematics
1 answer:
Lelechka [254]3 years ago
6 0

Answer:

Step-by-step explanation:

For x+3y=15

Take (6,3) and substitute the points:

6+3(3)=15

6+9=15

15=15

For 4 x + 2 y = 30 and substitute the points:

4(6)+2(3)=30

24+6=30

30=30

So, (6,3) is the solution of the given system of equations.

A chicken weighs t lbs. It needs to be cooked for 20 minutes per lb plus an extra 15 minutes. What is the total cooking time? Is
Nostrana [21]

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.

Find g(x), where g(x) is the translation 7 units up of f(x)=x2.
AfilCa [17]

Answer:

g(x)=x^2+7

g(x) in the form a(x-h)^2+k would be:

g(x)=(x-0)^2+7

Step-by-step explanation:

Given:

Parent function:

f(x)=x^2

Translation occurs 7 units up to get g(x)

Translation Rules:

f(x)\rightarrow f(x)+c

If c>0 the function shifts c units to the up.

If c the function shifts c units to the down.

So, from the above rules g(x) can be represented as:

g(x)=f(x)+7     [7 units up]

g(x)=x^2+7

Writing g(x) in the form a(x-h)^2+k where a, h, and\ k are integers.

g(x)=1(x-0)^2+7

g(x)=(x-0)^2+7
