0.4 * x = 68
x = 68/0.4
x = 170
check:
0.4 * 170 = 68
Answer:
4
Step-by-step explanation:
Frank has 5 cards.
Steve has 3 cards.
Pat has 9 cards.
Therefore, Pat has 4 more cards than Frank.
Hope this helps!
If by "coincide", in other words this is also known as intersect, it means that the solution to the system is that intersection point. For instance, if the intersection point of the 2 lines is (5,7) on the graph, it means that in both equations, x = 5 and y = 7. If you mean that the 2 equations result in the same line, it means that the 2 equations were really equal, but that one could be basic to be identical with the other. For example, if you have 2x + 2y = 8 and 4x + 4y = 16, they will give you the same line, and you can see that if you divide that second equation by 2 all the way crossways, it merely shows the first equation.
Answer:
that scale factor is 2
Step-by-step explanation:
A the side is 2.5
B the same stop as side a but its 5
so 2.5 to 5 is multiply 2
Answer:
or 
Step-by-step explanation:
step 1
Find the slope of the line
The formula to calculate the slope between two points is equal to

we have the ordered pairs
(3,-5) and (1,-9)
substitute the values



step 2
Find the equation in point slope form

Analyze two cases
<em>First case</em>
we have


substitute

<em>Second case</em>
we have


substitute

Note: The equation of the line in point slope form varies according to the point you choose, in contrast to the slope-intercept form
