Step-by-step explanation:
First solve for y,
7-y<2x
7-2x<y
y>-2x+7
your y intercept would be (0,7)
and your slope would be -2/1 so, you go down 2 and 1 to the right.
Since this is a greater than symbol, we have to shade above the line and the line would also be a dotted line.
Supplementary Angles:
Arithmetically speaking, the closest 2 supplementary angles can get (in 3 and 2 digits respectively) is the upwritten.
Complementary Angles:
Simply, in this case, for angles to be numerically as close as possible - make both the angles 45°.
Answer:
3x+y=8 and 3x+y=9
Step-by-step explanation:
Assume these two equations:
a1x+b1y+c1=0
a2x+b2y+c2=0
If (a1/a2) = (b1/b2) ≠ (c1/c2) than those two would have no solution.
In these case, take a look at the last option:
Re-write 'em as a standard form:
So (a1/a2) = (b1/b2) ≠ (c1/c2) is true here:
And they do not have any collision point
