the total cost of a bus ride and a ferry ride is $8.00. in one month, bus fare will increase by 10% and ferry fare will increase

ipn [44]

The bus fare is x, and the ferry fare is y.

x + y = 8

The bus fare will increase by 10% and the ferry fare will increase by 25%.

1.1x + 1.25y = 9.25

Multiply the first equation by -1.1:

-1.1x - 1.1y = -8.8

Add this to the original second equation.

0.15y = 0.45

y = 3

x + y = 8

x + 3 = 8

x = 5

The bus fare is $5, and ferry fare is $3.

Cannnn u helpp me ill be choosing brainliest

allochka39001 [22]

$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$

How to find amplitude and period from equation?

polet [3.4K]

If your graph is a COS or SIN graph :

$y = a \sin(bx) + c$
a is the Amplitude
and period is:
$\frac{360}{b}$

If your graph is a TAN graph :
$y = a \tan(bx) + c$
A TAN graph has no amplitude as it has no Maximum or Minimum value.
To find period :
$\frac{180}{b}$
