Inverse of 1.5x+4: 2(x-4) /3
Slope of 1.5x+4: m=1.5
Answer:
<h2>5x - y = 3</h2><h2>5x - y - 3 = 0</h2>
Step-by-step explanation:
y = 5x - 3 <em>it's a slope-intercept form</em>
<em />
y = 5x - 3 <em>subtract 5x from both sides</em>
-5x + y = -3 <em>change the signs</em>
5x - y = 3 <em>it's a standard form</em>
<em />
5x - y = 3 <em>subtract 3 from both sides</em>
5x - y - 3 = 0 <em>it's a general form</em>
Answer: non for sure
Step-by-step explanation:
Becuase X does not repeat its self
$160.00 earned per week divided by the $8.00 paid per hour equals how many hours worked ...
$160.00 / $8.00 = x
160 / 8 = x
20 = x
Answer:
s = 6, r = 8 or s = 4, r = 7
Step-by-step explanation:
2r - s = 10
2r = 10 + s
r = 5 + s/2 --(1)
rs - s^2 = 12 --(2)
sub (1) into (2):
(5 + s/2)s - s^2 = 12
5s + 0.5s^2 - s^2 = 12
-0.5s^2 + 5s - 12 = 0
s^2 - 10s + 24 = 0
(s - 6)(s - 4) = 0
therefore s = 6 or s = 4
when s = 6, r = 8 and when s = 4, r = 7
