Answer:
is this a equation for HW for is this random?
Step-by-step explanation:
Answer:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form:(30/19,2/19)
Equation Form: x=30/19, y=2/19
Day 1: $2.70 is added to the value of the share.
$43.85 + $2.70 = $46.55
Day 2: $2.70 is added to the value of the share.
$46.55 + $2.70 = $49.25
Day 3: $1.10 is subtracted from the value of the share.
$49.25 - $1.10 = $48.15
Day 4: $1.10 is subtracted from the value of the share.
$48.15 - $1.10 = $47.05
Day 5: $4.45 is subtracted from the value of the share.
$47.05 - $4.45 = $42.60
After 5 days, the value is $42.60, which is choice B.
Hope this helps!
Verify each of the solutions by substituting them back into the original equation <span><span>log<span>(−2a+9)</span>=log<span>(7−4a)</span></span><span>log<span>(-2a+9)</span>=log<span>(7-4a)</span></span></span> and solving. In this case, all solutions were found to be valid.<span>a=−<span>1</span></span>
