Answer:
they show parralel line and perpendicular line
if the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect.
the x and y intercept are different
two solutions
Answer:
21k^13
Step-by-step explanation:
when multiplying two variables that are raised to different powers you multiply the coefficient 7x3=21, then add the powers, 9+4=13 and you get 21k^13
Answer:$9504.80
Step-by-step explanation:
Every year, we have an increase of 9% interest. After two years, we will have 8000 * 1.09 ^2 = $9504.80
<u>Statement </u> <u>Reason</u>
1. AB = x + 16 1. Given
BC = 4x + 11
AC = 77
2. AB + BC = AC 2. Segment Addition Postulate
3. x + 16 + 4x + 11 = 77 3. Substitution Property
4. 5x + 27 = 77 4. Simplification <em>(added like terms)</em>
5. 5x = 50 5. Subtraction Property of Equality
6. x = 10 6. Division Property of Equality
7. AB = 10 + 16 7. Substitution Property
8. AB = 26 8. Simplification <em>(added like terms)</em>
Answer:
340.8 m
Step-by-step explanation:
Find the area of rectangles:
15 x 8 = 120
6x8=48
16x8=128
Find area of triangle:
1/2 5.6 x 16 = 44.8
Add together:
120 + 48 + 128 + 44.8 = 340.8 m
Hope this helps :)
