That point slope equation given does not pass through those points, the point slope equation y + 7 = -0.4(x - 10) does, though. The standard form of that would be
2x + 5y = -15
You can get that by distributing the -0.4 out
y + 7 = -0.4x + 4
You can then add 0.4x to both sides, and subtract 7 from both sides to get
0.4x + y = -3
Now some teachers may accept this, but in correct standard form the coefficient of x is a whole number, so you have to multiply both sides by 5 to get rid of the decimal, and you get
Answer:
36
Step-by-step explanation:
Hey There!
So if you didn't know all of the angles in a triangle add up to equal 180
so to find the missing angle we subtract the given angles from 180
180-90-54=36
therefore the missing angles is 36
The answer is in slope form : Y=1x+5
Reason: all you do is (rise/run) to get the slope. So take (5/5)=1x (slope). Also, your intercept is +5.
Answer:
270
Step-by-step explanation:
The mean is 228 and the standard deviation is 18.
2.3 standard deviations above the mean is:
228 + 2.3×18
228 + 41.4
269.4
Since scores are usually integers, we round up to 270.
