Answer:

Solve for the first variable in one of the equations, then substitute the result into the other equation.

Point Form:(7,6)

Equation Form: x=7, y=6

2x+y=20

6x-5y=12

First get y by its self

2x+y=20

y= -2x+20

Now plug into second equation for y

6x-5(-2x+20)=12

6x+10x-100

16x-100=12

16x=112

x=7

now plug in x value into first equation and solve for y

2(7)+y=20

14+y=20

y= 6

Now check by plugging x and y values back into equation

2(7)+6=20

6(7)-5(6)=12

They both work so x=7 and y =6

If r varies directly as w and the constant of variation is 12 what is the value of w when r =42

Airida [17]

r=kw

r=12w

42 = 12*w

divide by 12

42/12 =w

3.5 = w

How to solve this? Is the question correct? ty :)

Answer:

The proposition is true.

Step-by-step explanation:

Now we proceed to demostrate that expression given is true by algebraic means:

1) $\frac{x^{-1}+y^{-1}}{x^{-1}}+\frac{x^{-1}-y^{-1} }{y^{-1}}$ Given

2) $\frac{y^{-1}\cdot (x^{-1}+y^{-1})+x^{-1}\cdot (x^{-1}-y^{-1})}{x^{-1}\cdot y^{-1}}$ $\frac{a}{b} + \frac{c}{d} = \frac{a\cdot d+b\cdot c}{b\cdot d}$

3) $\frac{x^{-1}\cdot y^{-1}+y^{-2}+x^{-2}-x^{-1}\cdot y^{-1}}{x^{-1}\cdot y^{-1}}$ Distributive property/ $a^{b}\cdot a^{c} = a^{b+c}$

4) $\frac{x^{-2}+y^{-2}}{(x\cdot y)^{-1}}$ Commutative, associative and modulative properties/Existence of additive inverse/ $a^{b}\cdot c^{b} = (a\cdot c)^{b}$

5) $[(x\cdot y)^{-1}]^{-1}\cdot (x^{-2}+y^{-2})$ Commutative property/Definition of division

6) $(x\cdot y)\cdot (x^{-2}+y^{-2})$ $(x^{-1})^{-1}$

7) $x^{-1}\cdot y + x\cdot y^{-1}$ Distributive property/Associative property/ $a^{b}\cdot a^{c} = a^{b+c}$

8) $(x^{-1}\cdot y^{-1})\cdot y^{2} + (x^{-1}\cdot y^{-1})\cdot x^{2}$ Modulative property/Existence of additive inverse/ $a^{b}\cdot a^{c} = a^{b+c}$
