Answer: h(x) = 
<u>Step-by-step explanation:</u>
6x + y = 4x + 11y
<u> -y </u> <u> -y </u>
6x = 4x + 10y
<u>-4x </u> <u>-4x </u>
2x = 10y
<u>÷10 </u> <u> ÷10 </u>
= y
Since "y" represents h(x), then h(x) = 
Answer:
196
Step-by-step explanation:
The discriminant (Δ) is given by:

Where the polynomial is in the form:

In this problem, a = 1, b = 0, and c = -49. Thus, plugging it into the formula:

Thus, the discriminant of x² – 49 = 0 is 196.
The answer is 304.8 millimetres
Answer:
5.58*10^7
Step-by-step explanation:
Recall that 10^a*10^b = 10^(a+b). Thus, 10^5*10^2 = 10^7.
Thus, (1.8 x 10^5)(3.1 x 10^2) = (1.8)(3.1)*10^7 = 5.58*10^7
Answer:
75
Step-by-step explanation:
First divide 2/5 to get 0.4. Then divide 30 by 0.4 to get the answer. A simple way to think about it is how many 0.4 grams are in 30 gram tube.
