Cannnn u helpp me ill be choosing brainliest

$1) y=-5^{-x}, y = x+5 ,
\\ \\ -5^{-x}=x+5
\\ \\ ln(-5^{-x})=ln(x+5)
\\ \\ ln(- \frac{1}{5^{x}} )=ln(x+5),

you cannot find ln of negative number, so it is going to be

 "0" solutions.
$

The graphs of these equations will not intersect.

$2) y = 4(1.2)^{x}, y = x+7
\\ \\ x+7= 4(1.2)^{x}

graphs have 2 intersects, so two solutions.$

3) $y= {0.5}^{x} , y =6, \ 6=0.5^{x}

One intercept. so one solution$
