f(a) =-2a^2-5a+4
so
f(-3) = -2(-3)^2 -5(-3) + 4
f(-3) = -2(9) + 15 + 4
f(-3) = -18 + 19
f(-3) = 1

hope it helps

-3y + 14 + y = 12

Step 2: Solve for y

Combine like terms [Addition]: -2y + 14 = 12
[Subtraction Property of Equality] Subtract 14 on both sides: -2y = -2
[Division Property of Equality] Divide -2 on both sides: y = 1

Solve for y. ln(y-1)-ln2=x+ln x

alexandr402 [8]

$ln(y - 1) - ln(2) = x + ln(x)$
$e^{ln(y - 1) - ln(2)} = e^{x + ln(x)}$
$\frac{e^{ln(y - 1)}}{e^{ln(2)}} = e^{x} * e^{ln(x)}$
$\frac{y - 1}{2} = e^{x} * x$
$\frac{1}{2}y - \frac{1}{2} = xe^{x}$
$2(\frac{1}{2}y - \frac{1}{2}) = 2xe^{x}$
$y - 1 = 2xe^{x}$
$y = 2xe^{x} + 1$
