Answer:
Step-by-step explanation:
The equations are
Substituting the first equation in the second we get
So, the required values are
Three and six tenths. The decimal point is always expressed as "and." the digit after the decimal point is always expressed by tenths.
Answer:
the first one is 5/12 and the second one is 6/28. Hope this helps and have a nice day:)
Answer:
Step-by-step explanation:
Find the slope of the line AB.
<u>The slope:</u>
- m = (11 - 9)/(11 - 7) = 2/4 = 1/2
Since the altitude is perpendicular to AB, it has a slope of -2.
The line with the slope of -2 and passes through point C(6, 16).
<u>Use point-slope equation to find the line:</u>
- y - 16 = -2(x - 6)
- y - 16 = -2x + 12
- y + 2x = 16 + 12
- 2x + y = 28
A = 2, B = 1, C = 28
Answer: Yes, they both equal -7/2
