Put the equation in standard form with a positive x coefficient. 2y+5=-4(x+2)

umka21 [38]

The standard form of equation is: 4x+2y = -13

Step-by-step explanation:

the standard form of a linear equation in two variables is given by:

$ax+by = c$

Given equation is:

$2y+5=-4(x+2)$

Distributing -4 into the round bracket

$2y+5 = -4x-8$

Adding 4x on both sides

$4x+2y+5 = -4x-8+4x\\4x+2y+5 = -8$

subtracting 5 from both sides

$4x+2y+5-5 = -8-5\\4x+2y = -13$

The standard form of equation is: 4x+2y = -13

Answer:

Answer Choice A (8, eight)

Step-by-step explanation:

To begin, add all of the marbles together. When finished, the answer should be 20. Because the variable 20 equals 100, you divide 4 by 100. You will get 0.04 as a result. This multiplied by 20 equals 8. Finally, the answer is A.

The circumference of a circle is 604 cm. What is the diameter of the circle?

Marta_Voda [28]

Step-by-step explanation:

The Circumference is:

$c = 2\pi \: r$

Radius r is:

$r = \frac{d}{2}$

So,

$c = \pi \: d \\ d = \frac{c}{\pi} \\ d = \frac{604}{\pi} \: cm$
