Wouldn't you use sin, cos, tan?
Answer:
it will take 4 hours( I'm not so sure)
Step-by-step explanation:
$25x $15
------- = ------------- + 75
1h. 1h
25x = 100
x =100/25
x = 4
9u-9t=18
original no. is 10t+u
reversed no. is 10u+t
so its (10u+t)-(10t+u)=18
which gives 9u-9t=18
<span>4x+2y=-6
2y = -4x - 6
y = - 2x - 3
slope = -2
</span><span>y-intercept when x = 0
so y = -3
answer
slope = -2
</span><span>y-intercept (0,-3)</span>
