Answer:

\left \{ {{y=-1} \atop {x=-4}} \right.

Step-by-step explanation:

\left \{ {{y=\frac{3}{4} x+2} \atop {5x+4y=-24}} \right.  \left \{ {{y=\frac{3}{4}x+2 } \atop {5x+4*(\frac{3}{4}x+2)=-24 }} \right. \left \{ {{y=\frac{3}{4}x+2 } \atop {5x+3x+8=-24}} \right.  \left \{ {{y=\frac{3}{4}x+2 } \atop {8x=-32}} \right. \\\left \{ {{y=\frac{3}{4}x+2 } \atop {x=-4}} \right.  \left \{ {{y=\frac{3}{4}*(-4)+2 } \atop {x=-4}} \right.  \left \{ {{y=-3+2} \atop {x=-4}} \right. =>\left \{ {{y=-1} \atop {x=-4}} \right.

Assume that y varies inversely with x. If y=7 when x=2/3, find y when x=7/3
fgiga [73]
Inverse variation is of the form:

y=k/x, which we can express as:

yx=k  we are given the point (2/3, 7) so we can solve for k

7(2/3)=k

14/3=k

y=14/(3x), so when x=7/3

y=(14/3)/(7/3)

y=(14/3)(3/7)

y=2

Please help me!<br> Hint: the number is negative
wel

Answer:

-36 goes into the box

Step-by-step explanation:

Let the number be x,  then


(m^x)^{\frac{1}{3}}=m^{-12}


We now use the following property of exponents to simplify the left hand side of the equation.

(a^m)^n=a^{mn}

This implies that;

m^{x\times \frac{1}{3}}=m^{-12}


\Rightarrow m^{\frac{x}{3}}=m^{-12}


Since the bases are the same, we equate the exponents to get;


{\frac{x}{3}=-12


We now multiply both sides by 3 to get;


\frac{x}{3}\times 3=-12\times 3


\Rightarrow x =-36


Therefore the number that goes into the box is -36

Which of the following ( 15, 20, 30, 57 ) is the product of exactly three different prime numbers?
Andrei [34K]

Answer:

30=2*3*5, so it's 30

Step-by-step explanation:

15=3*5, so it's not 15

20=2*2*5, so it's not 20

30=2*3*5, so it's 30

57=19*3, so it's not 57
