So the first step to solving this problem is to distribute the \frac{1}{4}
to what's inside the parenthesis. This means multiply \frac{1}{4} by 4x and 15.
After that, this is what you shoud have.
\frac{4x}{4}  +  \frac{15}{4} = 24
This should be simplified
1x = 24 - \frac{15}{4}

\frac{15}{4} is equal to 3.75
x = 20.25
20.25 is equal to  \frac{81}{4}

What is the equation of the line 2-3y = 18 in slope-intercept form?
il63 [147K]
The person above me got that horrible wrong, do not put that.

You also wrote the question wrong, please be more careful when posting.

x-3y=18

Move x to the other side by subtracting it since it’s positive.

-3y = -x + 18

Divide the whole equation by -3 to find the value of just 1 y.

-3y/-3 = -x/-3 + 18/-3

y = 1/3x -6

What are the roots of f(x) = x2 – 48? –48 and 48 –24 and 24 Negative 8 StartRoot 3 EndRoot and 8 StartRoot 3 EndRoot Negative 4
Ivanshal [37]

Answer:

x=4\sqrt{3},\:x=-4\sqrt{3} are the roots.

Step-by-step explanation:

x=4\sqrt{3},\:x=-4\sqrt{3}

Considering the expression

x^2\:-\:48

Solving

x^2-48=0

x^2-48+48=0+48

x^2=48

\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}

x=\sqrt{48},\:x=-\sqrt{48}

Solving

x=\sqrt{48}

  = \sqrt{2^4\cdot \:3}

  \mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b}

  = \sqrt{3}\sqrt{2^4}

  \mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{a^m}=a^{\frac{m}{n}}

  \sqrt{2^4}=2^{\frac{4}{2}}=2^2

  =2^2\sqrt{3}

  =4\sqrt{3}

So,

x=4\sqrt{3}

Similarly,

x=-\sqrt{48}=-4\sqrt{3}

Therefore, x=4\sqrt{3},\:x=-4\sqrt{3} are the roots.
