Answer:
see below
Step-by-step explanation:
The first equation is in slope-intercept form, so you can see that the boundary line has a slope of -2 and goes through the point (x, y) = (0, -4). Since the comparison is "<", the line is dashed and shading is below it.
The second equation is that of a vertical boundary line at x=-3. It is solid, because the comparison includes the "equal" case. Shading is to the right of it, where x values are greater than -3.
Opposite angles are equal so the equation is
x + 71 = 108 (A)
Convert all fractions to improper, then multiply numerators, multiply denominators. You get 180/240, which reduces to 3/4 cubic meter.
Answer:
5/4
Step-by-step explanation:
9a + 2b = 5a - 7b
Bringing like terms to one side of the equation,
9a - 5a = 7b - 2b
4a = 5b
By cross multiplication,
a/b = 5/4
