Answer:

(-2, -4) or x = -2 y = -4

Step-by-step explanation:

Solve with subsitution

y-3x=2

y=-2x-8

1. Substitute -2x - 8 in for the y in y - 3x = 2 (-2x - 8) - 3x = 2

2. Solve for x. Combine like terms. -5x - 8 = 2

3. Solve the one step equation. +8 +8

-5x = 10

-5 -5

x = -2

4. Substitute the -2 in for x in either equation. y = -2x - 8

y = -2(-2) - 8

y = 4 - 8

y = -4

Answer:

y-3x=2......1

y=-2x-8 ......2

substituting value of y in equation 1

-2x-8-3x=2

-5x=2+8

x=10/-5=-2

substituting value of x in equation 1

y-3×(-2)=2

y+6=2

y=2-6=-4

x=-2

y=-4

Which expression is equivalent to sqrt8x^7y^8? assume x>0

Ilia_Sergeevich [38]

Answer:

$\sqrt{8x^7y^8$ $= 2x^3y^4 * \sqrt{2x}$

Step-by-step explanation:

Given

$\sqrt{8x^7y^8$

Required

Evaluate

$\sqrt{8x^7y^8$

Separate each factor with multiplication sign

$\sqrt{8*x^7*y^8$

Express 8 as 4 * 2 and $x^7$ as $x^6 * x$

$\sqrt{4 * 2 *x^6 * x*y^8$

Split each factor

$\sqrt{4} * \sqrt{2} *\sqrt{x^6} * \sqrt{x}*\sqrt{y^8}$

Evaluate $\sqrt4$

$2 * \sqrt{2} *\sqrt{x^6} * \sqrt{x}*\sqrt{y^8}$

Apply law of indices:

$2 * \sqrt{2} * x^{6*\frac{1}{2}} * \sqrt{x} * y^{8*\frac{1}{2}}$

$2 * \sqrt{2} * x^3 * \sqrt{x} * y^4$

Reorder

$2* x^3 * y^4 * \sqrt{2} * \sqrt{x}$

$2x^3y^4 * \sqrt{2} * \sqrt{x}$

$2x^3y^4 * \sqrt{2*x}$

$2x^3y^4 * \sqrt{2x}$

$2x^3y^4 \sqrt {2x$

Hence:

$\sqrt{8x^7y^8$ $= 2x^3y^4 * \sqrt{2x}$

ANSWER ALL (a-d) FOR 30 POINTS - EASY

djverab [1.8K]

Part a.

The perimeter formula is: P = 2w + 2L

Your answer for part A is P = 2w + 2L

Part b.

They tell us in part b, that:
w = 6L + 20

Substitute that into what we got for part a.

P = 2(6L + 20) + 2L
P = 12L + 40 + 2L
P = 14L + 40

Your answer for partb is P = 14L + 40

Part c.

So we take what we got from part b, and solve for L.

P = 14L + 40
14L = P - 40

$L = \boxed{\frac{P-40}{14}}$

That is your answer for part 3 ^

part d.

Plug in w = 32 into what we first got in part b.

w = 6L + 20
32 = 6L + 20
6L = 12

L = 2

Your answer for part d is L = 2

:D
