Answer:86
Step-by-step explanation:
You would do multiplication first so 18x2 = 36 then you would add 36+50 which equals 86
6x-2y+5. Here you just do addition/subtraction with the coefficients on the variables.
Answer:
If two sides of a triangle are unequal, the angle opposite to the longer side is larger (or greater). You may prove this theorem by taking a point P on BC such that CA = CP.
Step-by-step explanation:
That's how you can prove which side is bigger
A)
The slope-intercept form:
m - slope
b - y-intercept
The formula of a slope:
We have the points (2, 5.1) and (-1, -0.5). Substitute:
Therefore we have:
Put the coordinates of the point (-1, -0.5) ot the equation:
<em>multiply both sides by 2</em>
<em>add 
to both sides</em>
<em>divide both sides by 2</em>
Answer: 
-------------------------------------------------------------------------
B)
We have the points (-2, 3) and (3, -4).
Calculate the slope:
Therefore we have:
Put the coordinates of the point (-2, 3) to the equation of a line:
<em>subtract 
from both sides</em>
Answer: 
It isn't because since 9 is the product of 3×3, you multiply the 6 by 3 as well, which makes 18.
