Answer:
Step-by-step explanation:
< 1 = 110
< 2 = 180 - 110 = 70
<5 = 180 - 110 = 70
<6 = <1 = 110
==================
<9 = 103
<13 = 180 - 103 = 77
<10 = <13 = 77
<14 = <9 - 103
====================
<2 = < 4 = 70 Property of l || m
<3 = <1 = 110 Same as above
<7 = <5 = 70 Same as above and vertical angles.
<6 = <8 = 110 Same as above
=====================
<11 = < 9 = 103 Parallel line property
<15 = <13 = 77 Same as above
<12 = <10 = 77 Same as above
<16 = <15 = 103 Parallel line property.
Answer:
The expression is not factorable with rational numbers
Answer:
$20500
Step-by-step explanation:
26500-(.12*26500)=23320 For 1 year
23320-(.12*23320)=$20521.60 For 2 years
Answer:
(x1, y1) = (1, 3)
(x2, y2) = (4, 12)
Step-by-step explanation:
y= x^2 - 4
y= 5x - 8
(substitute the value for y)
x^2 - 4 = 5x - 8
(solve the equation)
x = 1
x = 4
(substitute the values)
y = 5 × 1 - 8
y = 5 × 4 - 8
(solve the equations)
y = -3
y = 12
( the possible solutions are)
x1, y1 = 1, -3
x2, y2 = 4, 12
(check the solutions)
-3 = 1^2 - 4
-3 = 5 × 1 - 8
12 = 4^2 - 4
12 = 5 × 4 - 8
(simplify)
-3 = -3
-3 = -3
12 = 12
12 = 12
(the ordered pairs are the solutions)
So her best jump is 12% of her 1st jump. So
this is:
best jump = 1.12 * 4.25 m
best jump = 4.76 m
Since the winning jump is 15% lower, so this is only 85%
of the best jump hence:
winning jump = 0.85 * 4.76 m
winning jump = 4.046 m = 4.05 m
