In this equation you can eliminate the x value
multiply the second equation by -2 and you get:
-2x - 2y = -10
when you add the two equations the x factors will cancel
2x + 3y = 6
- 2x - 2y = -10
---------------------
y = 16
you can find the x value by plugging the y value that you now know into one of the equations that you started off with.
Answer:
1.rocky
Step-by-step explanation
1.we have the add the powers of x,not multiply.
Answer:
Graph (0, 25) and (50, 0)
Step-by-step explanation:
Intercept form of an equation for a line is ...
x/(x-intercept) + y/(y-intercept) = 1
Dividing each equation by the constant on the right can put it into this form.
First equation:
t/42 + f/42 = 1
Second equation:
t/50 + f/25 = 1
This tells you the second equation can be graphed using the points ...
... (50, 0) and (0, 25) . . . . . matches the second selection
It would be over 12% (11.98375085%)
Lets break it down:
You need to find what percent 177 is of 1,477.
To do this, you need to do 177÷1,477 to get 0.1198 and so on
(To find a percent from a decimal, you move the decimal point 2 places to the right)
If you find the percent, it would be 11.98 (and so on) percent. Rounded to the nearest 1%, it would be 12%

In similar figures, angles or sides are proportional, but in congruence, figures are exactly the same- angles, sides, and everything.
Additionally, similar figures always have the same shape, but not always the same size. But in congruence, figures always have the same shape AND size.
So, corresponding sides for similar figures should be proportional (that is, have the same scale factor. And corresponding sides in congruent figures must be exactly the same.
Hope that helps!
