It would be $33.15 because if you multiply $52 x 60% you would get 31.2. Then if you add 31.2 + 6.25% you would get $33.15.

Answer:

52 X 60 equals 3120, divide that by 100, to get 31.20, and then do 52.00-31.20 to 20.8. plus sales tax, would equal, 20.8 X 6.25% = 1.3. add that onto the original answer to get the final answer, 22.1. Hope this helps! :)

Solve for the variable. 3/4x = -24

sleet_krkn [62]

Hello!

Answer:

$\huge\boxed{x = -32}$

3/4x = -24

To isolate the "x" variable, divide both sides by 3/4 (multiply by its reciprocal, or 4/3)

3/4x · 4/3 = -24 · 4/3

x = (-24 · 4) / 3

x = -32.

Phoenix [80]

Answer:

y=-4/6+2

Step-by-step explanation:

The rise is -4, and the run is 6. Rise over run means that the slope is -4/6. the Y intercept is 2. Therefore y=-4/6+2.

Determine if the function is a polynomial function. If the function is a polynomial function, state the degree and the leading c

EleoNora [17]

Answer:

The correct option is 2. The given function is a polynomial of degree 4 with a leading coefficient of 36.

Step-by-step explanation:

A polynomial function is defined as

$P=a_0x^n+a_1x^{n-1}+....+a_{n-1}x+a_n$

The given function is

$f(x)=(2x+3)^2(3x+5)^2$

Using perfect square trinomial property.

$f(x)=(4x^2+12x+9)(9x^2+30x+25)$ $[\because (a+b)^2=a^2+2ab+b^2]$

Using distributive property, we get

$f(x)=4x^2(9x^2+30x+25)+12x(9x^2+30x+25)+9(9x^2+30x+25)$

$f(x)=36x^4+120x^3+100x^2+108x^3+360x^2+300x+81x^2+270x+225$

$f(x)=36x^4+228x^3+541x^2+570x+225$

The given function is a polynomial of degree 4 with a leading coefficient of 36.

Therefore the correct option is 2.
