Answer:
x=56
Step-by-step explanation:
· 
then cross multiply
4200=75x
x=56
7x + 4 + 9x = 180
16x = 176
x = 11
9x = 9x11 = 99
7x + 4 = 7(11) + 4 = 77 + 4 = 81
<span>in order to form a rectangular image, each angle needs to be equal 90 degreesn
99 - 9 = 90
81 + 9 = 90

Answer:
0
Step-by-step explanation:
The slope of a horizontal line is zero (0). For any finite "run", the "rise" is zero.
slope = rise/run = 0/run = 0
Answer:
Graph A.
Step-by-step explanation:
When Johnny starts moving <em>more </em>lawns, this means, in fewer weeks, he will have more total lawns mowed. We can see on the first graph, the blue line shows an increase of lawns mowed with fewer weeks.
The fact that a connection is proportional if its graph is a line that runs through its origin should be stressed. This can be used to find the ratio in the proportional relationship.
<h3>How to explain the information?</h3>
When the graph of a connection is a line passing through the origin, the connection is proportionate. If it is not a line or ray that fails to do this, the ratio is not proportional. The equation for the proportionality constant is K = y/x. This is the same equation used to get the slope of a straight line with respect to the origin.
If the graph of a relationship is a line or ray that goes through the origin, the relationship is proportional. If the line or ray does not pass through the origin, it is not proportional.
