$8y-10=6y-2$

$8y-10=6y-2:y$ $| Solve \ for \ y|$

$8y=6y-2+10
 
$ $|Add \ 10 \ to \ both \ sides|$

$
8y=6y+8
 
$

$
8y-6y=8
 
$ $|Subtract \ 6y \ from \ both \ sides|$

$2y=8$

$y=8/2$ $|Divide \ both \ sides \ by \ 2|$

$y=4$

$\star \ Hence \ solved$

$8y-10=6y-2
 \\ 8y-6y = -2 +10 \\ 2y=8 \\ y=4$

Solve the equation: 2y+4^2=64

JulsSmile [24]

Answer:

$2y + {4}^{2} = 64 \\ 2y + 16 = 64 \\ 2y = 64 - 16 \\ 2y = 48 \\ \\ y = \frac{48}{2} \\ \\ y = 24$

I hope I helped you^_^

The rabbit population in a certain area is 500% of last year's population. There are 700 rabbits this year. How many were the

Ksenya-84 [330]

For this case we have the following data:

700 rabbits that represent 500% of the population of last year. So, to obtain the rabbit population of last year, we developed a rule of three:

700 -----------> 500%

x ---------------> 100%

Where x represents the rabbit population of last year.

Clearing x we have:

$x = \frac{ 100 * 700}{500}$

$x = 140$ rabbits

In this way, last year there was a population of 140 rabbits.

Answer:

140 rabbits

Which equation represents the line that is perpendicular to y = 5 and passes through (-4,-3)?

kenny6666 [7]

Answer:

The required equation is: y=-3

Option D is correct.

Step-by-step explanation:

We need to write equation of line that is perpendicular to y = 5 and passes through (-4,-3).

The equation of line in slope-intercept form is expressed as: $y=mx+b$

where m is slope and b is y-intercept.

Finding Slope:

Comparing with the given equation y=5, the slope m =0

The slope of required line will be opposite reciprocal of 0 as both lines are perpendicular. so it will be m=0

Finding y-intercept

The y-intercept can be found using slope m=0 and point (-4,-3)

$y=mx+b\\-3=0(-4)+b\\b=-3$

So, y-intercept b is b=-3

The equation of required line having slope m=0 and y-intercept b=-3 is

$y=mx+b\\y=0(x)-3\\y=-3$

So, required equation is: y=-3

Option D is correct.
