Step-by-step explanation:

y=-2x-4

y=3x+3

-----------

-2x-4=3x+3

-2x-3x-4=3

-5x-4=3

-5x=3+4

-5x=8

x=8/-5

y=-2(-8/5)-4

y=16/5-4

y=16/5-20/5=-4/5

Answer:

x=-8/5, y=-4/5. (-8/5, -4/5).

Step-by-step explanation:

y=-2x-4

y=3x+3

-----------

-2x-4=3x+3

-2x-3x-4=3

-5x-4=3

-5x=3+4

-5x=8

x=8/-5

y=-2(-8/5)-4

y=16/5-4

Find x if L is between N and M, and NL = (6x - 5), LM = (2x + 3), and NM = (3x+13)?

anastassius [24]

Answer:

x = 3

Step-by-step explanation:

Here, we want to find the value of x

By mathematical convention;

NM = NL + LM

Now, substitute individual values

3x + 13 = (6x-5) + (2x + 3)

3x + 13 = 6x-5 + 2x + 3

3x + 13 = 8x -2

Collect like terms

8x -3x = 13 + 2

5x = 15

x = 15/5

x = 3

What is the radical expression that is equivalent to the expression 27 1/5? Enter your answer as a radical. For example, if your

yuradex [85]

Answer:

$27^{\frac{1}{5} }=\sqrt[5]{3^3}$

Step-by-step explanation:

we are given

$27^{\frac{1}{5} }$

we can use rule to change exponent into radical

$\sqrt[n]{a} =a^{\frac{1}{n} }$

so, we can write as

$27^{\frac{1}{5}}=(3\times 3\times 3)^{\frac{1}{5}}$

$27^{\frac{1}{5}}=(3^3)^{\frac{1}{5}}$

now, we can use rule

and we can write our term as

$27^{\frac{1}{5} }=\sqrt[5]{3^3}$
