The distributive property. You need to district it's 7 to x and -1.
Answer:
no it is not a proportional relationship
The bus fare is x, and the ferry fare is y.
x + y = 8
The bus fare will increase by 10% and the ferry fare will increase by 25%.
1.1x + 1.25y = 9.25
Multiply the first equation by -1.1:
-1.1x - 1.1y = -8.8
Add this to the original second equation.
0.15y = 0.45
y = 3
x + y = 8
x + 3 = 8
x = 5
The bus fare is $5, and ferry fare is $3.
Answer:
A sequence of transformation can move two congruent figures to the same place (vertical / horizontal shifts). This causes them to perfectly overlap, proving their congruency.
A sequence of transformations can be used to show that something is similar, because if one were to transform a figure with only shrinks / stretches, one can shrink / stretch them to make them congruent. If only shrinks or stretches were done, and if the result of the transformation is congruent to the other figure, then the figures are similar (sides are proportional and shrinking/stretching them proves proportionality to other figure).
Answer:
undefined
Step-by-step explanation:
To find the slope of the line between two points, use the slope formula 
. 
and 
represent the x and y values of one point the line passes through, and 
and 
represent the x and y values of another point the line also passes through. Therefore, use the x and y values of the points (0,3) and (0,4) to find the slope. Substitute them into the formula in the right order:
However, we can't divide 1 by 0. Therefore, the slope is undefined. (You could also graph the points to see that they form a vertical line, and all vertical lines have an undefined slope.)
