Answer:

f(x)=-2*(x-3)+5 when x<u><</u>3

g(x)=x(x-3)+5 when x>3

Step-by-step explanation:

|   | is absolute function meaning the value must be larger than or equal to zero.

So | x-3 | = -(x-3) when x<u><</u>3

f(x)=-2*(x-3)+5 when x<u><</u>3


| x-3 | = (x-3) when x>3

g(x)=2*(x-3)+5 when x>3

Answer:

f(x) = -2( x - 3) + 5, x \leq 3\\\\g(x) = 2(x-3)+5, x > 3

Step-by-step explanation:

turning pt of the abs fn |x-3| is at x=3

2|x-3|=-2(x-3), x\leq 3\\\\2|x-3|=2(x-3), x>3

so

f(x) = -2( x - 3) + 5, x \leq 3\\\\g(x) = 2(x-3)+5, x > 3

Which simplified fraction is equal to 0.53? 1) 24/45 2) 8/15 3) 48/90 4) 5/9
Shalnov [3]

To express a decimal number (with a finite decimal expression) in a fraction, you work like this: the numerator is the number without decimale separator (you simply pretend it's not there), while the denominator will be 10^n, where n is the number of digits after the decimal separator.

So, in your case, the number without decimal separator is 53, and you have two digits after the decimal separator, so the fraction will be

0.53 = \cfrac{53}{10^2} = \cfrac{53}{100}

which is irreducible.

iris [78.8K]

Answer:

the answer i think is $259200

Step-by-step explanation:

if the bank charges 7.2% every year, and in this case it's 4 years, then that would mean it would be 28.8%(7.2 x 4), which means the answer would be 9000 x 28.8 which is 259200.

Hope it helped

Solve the equations PLEASEE<br><br> -1=3x-2<br><br> -3x=9<br><br> -10=-5x
Ilia_Sergeevich [38]

Answers are in bold:

-1=3x-2

add 2 to both sides

-1+2=3x-2+2

1=3x

divide both sides by 3

1÷3=3x÷3

1/3=x

-3x=9

divide both sides by -3

-3x÷-3=9÷-3

x=-3

-10=-5x

divide both sides by -5

-10÷-5=-5x÷-5

2=x

I hope this is good enough:

two lines intersect.One has gradient 4 and y-axis intercept 3. The other has gradient 6 and cuts the y-axis at (0,1). What is th
timurjin [86]

Answer:

(1, 7 )

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Then the equations of the 2 lines are

y = 4x + 3 → (1)

y = 6x + 1 → (2)

Substitute y = 6x + 1 into (1)

6x + 1 = 4x + 3 ( subtract 4x from both sides )

2x + 1 = 3 ( subtract 1 from both sides )

2x = 2 ( divide both sides by 2 )

x = 1

Substitute x = 1 into either of the 2 equations for corresponding value of y

Substituting into (1)

y = 4(1) + 3 = 4 + 3 = 7

Point of intersection = (1, 7 )
