$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$

If P(A) = 0.996, what is the value of P(A)?

andrew11 [14]

Answer:

$p(a) = 0$

Step-by-step explanation:

$p(a) = 0.966$

Find the derivative of the fraction

$p(a) = \frac{d}{da} ( 0.966)$

Convert the decimal number to a fraction

$p(a) = \frac{d}{da} ( \frac{249}{250} )$

The derivative of a constant is always 0

$p(a) = 0$

Which is a true statement?

Galina-37 [17]

As a negative number cannot be larger than a positive number, the answer is not A.
6.52 is larger than 6.5 so it cannot be B.
A smaller negative number is larger than a big negative number so the answer is not C.

The answer is D. as -2.8 is larger than -3.5
