Answer:
3 centimeters
Step-by-step explanation:
You can find this by dividing 54 by 18, or if you know your timetables, you know that 18x3 is 54.
Answer:
-72=-12y-20x
Step-by-step explanation:
-72=2y^2-16y-20x
square the 2 keeping the variable
-72=4y-16y-20x
Then combine like terms in this case the numbers followed by y's
-72=-12y-20x
This is the standard form as there is nothing else you can combine to break this down any further
Answer:
See the attachment for the appropriate choice.
Step-by-step explanation:
Both equations are in slope-intercept form. Both have a y-intercept of -2, so only a graph where the lines cross at (x, y) = (0, -2) is a viable choice.
In both cases, the inequality requires that values of y be "less than (or equal to)" those described by the line. Hence, the shading will be below both lines.
