Answer:
The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept.
Step-by-step explanation:
The y-intercept of this line is the value of y at the point where the line crosses the y axis.

A(x) = 1000(1+.17)x
because the 17 percent would have to be changed to a decimal form
Answer:
B = minus 15 is greater than 21 = as the line stops at 3^2 and shows 15 with shaded circle
It stops at -5^2 open circle and -5 x -5 = = 25
So if we use a value more than this -4.6 x -4.6 = 21
Answer:
I think that A, B, and C are correct.
Step-by-step explanation:
1. Since measures 2 and 3 are a linear pair, they equal 180 degrees. A is correct.
2. Since measures 3 and 4 are also a linear pair, they too equal 180 degrees. B is correct.
3. Measures 2 and 3 are already established to be 180 degrees (check answer 1) , and measures 3 and 4 are also 180 degrees (check answer 2). Since they are both 180 degrees, they are congruent (equal), so C is correct.
D is NOT correct. Measures 1 and 3 are equal because they are vertical angles. We also know that they are acute angles (less than 90) so adding them together will equal less than 180 degrees.
Measures 2 and 4 are equal because they are vertical angles, and they are obtuse (more than 90 degrees). Adding them together will equal more than 180 degrees.
Logic tells us that something less than 180 CANNOT be equal to something more than 180. This proves that 2 and 4 and 1 and 3 are not congruent.
D is WRONG
6 1 / 5 = 31 / 5;
8 3 / 10 = 83 / 10;
But, 31 / 5 = 62 / 10 ;
62 / 10 - ( - 83 / 10 ) = 62 / 10 + 83 / 10 = 145 / 10 = 29 / 2 .
