The process is equating,
a) take the two equations and equate them
0.25x + 0.58 = 1.5x - 5.4
(25x+58)/100 = (150x - 54)/100
25x + 58 = 150x - 54
150x - 25x. = 58+ 54
125x = 112
x = 125/112 is nearly 1.116
b) do the same thing ( the answer is 50 )
Answer:
9.233 ft, 23.233 ft
Step-by-step explanation:
If the shorter leg is x, then the longer leg is x+14 and the Pythagorean theorem tells you ...
x^2 + (x +14)^2 = 25^2
2x^2 +28x +196 = 625
x^2 +14x = 214.5
x^2 +14x +49 = 263.5
(x +7)^2 = 263.5
x = -7 +√263.5 ≈ 9.23268
The two leg lengths are √263.5 ± 7 feet, {9.23 ft, 23.23 ft}.
Answer:
?
Step-by-step explanation:
No, 14 and -7 are different numbers
Answer:
Step-by-step explanation:
The slope-intercept form of an equation of a line:
Parallel lines have the same slope. Therefore if given line is
then the slope of our line is .
We have the equation:
The line passes through (2, 1). Put the coordinsted pf the point to the equation:
<em>subtract 10 from both sides</em>
Finally:
