Answer:

x=8.499

y=0.167

Step-by-step explanation:

the equation says:x^2-9y^2=72....(1)

x+3y=9.......(2)

divide (2) from (1),it becomes:

x-3y=8

making x subject of formula,

x=8+3y....(3)

submitting (3) into (1),it becomes

(8+3y)^2-9y^2=72

64+48y=72

48y=72-64=8

y=8/48=0.167......(4)

submitting (4) into (2),it becomes

x+3(0.167)=9

x+0.501=9

x=9-0.501

x=8.499

A function of the form f(x) = abx is modified so that the b value remains the same but the a value is increased by 2. How do the

ira [324]

We are given

$f(x)=a(b)^x$

Here , we are given that it is modified so that the 'b' value remains the same but the 'a' value is increased by 2

so, we can write our function as

$f(x)=(a+2)(b)^x$

Domain:

Domain is all possible values of x for which any function is defined

We can see that there is no change in x

so, domain will remain same

Range:

Range is all possible value of y for which x is defined

so, lowest value of y will be 2

so, range is

$(-\infty,\infty)$

Answer is

domain will remain same

range is $(-\infty,\infty)$
