What is the equation of the line that has a slope of m = 2 and passes through the point (-5, -6)?

Alenkinab [10]

Answer:

$y=2x+4$

Step-by-step explanation:

You can solve this two ways: insert the values into point-slope form and simplify to solve for y, converting it to slope-intercept form, or insert the values into slope-intercept form, solve for b, and insert b. We'll do both :)

Point-slope form:

$y-y_{1}=m(x-x_{1})$

Where:

$m$ is the slope

$x_{1}$ and $y_{1}$ are corresponding coordinate points $(x,y)$

Insert the given values:

$m=2\\\\(-5_{x_{1}},-6_{y_{1}})\\\\y-(-6)=2(x-(-5))\\\\y+6=2(x+5)$

Solve for y. Expand the right sie using the distributive property:

$y+6=2(x)+2(5)\\\\y+6=2x+10$

Isolate the variable. Subtract 6 from both sides, canceling out the 6 on the left:

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

OR

Slope-intercept form:

$y=mx+b$

Where:

$m$ is the slope
$b$ is the y-intercept
$x$ and $y$ are corresponding coordinate points $(x,y)$

Insert the given values:

$m=2\\\\(-5_{x},-6_{y})\\\\-6=2(-5)+b$

Simplify the multiplication:

$-6=-10+b$

Solve for b. Add 10 to both sides, canceling out the 10 on the right:

$-6+10=-10+10+b\\\\4=b$

The value of b is 4. Insert the appropriate information into the equation. When using slope-intercept form, you don't plug in the coordinate points:

$y=2x+4$

Two less than the product of 8 and a number is 8

Eva8 [605]

Answer:

x=1.25

Step-by-step explanation:

Let us replace the number with the variable "x". You will then get this equation:

8x-2=8

Move the -2 to 8 and you would get the equation:

8x=8+2

Simplify:

8x=10

Simplify:

x=10/8

You would then get the answer "x=1.25"

I hope this helps :)

An aquarium has dimensions 2x feet, (x – 1) feet, and (x + 2) feet. The aquarium volume must be no more than 280 cubic feet.

Lina20 [59]

Answer:

$x^3+x^2-2x\leq140$

Step-by-step explanation:

This is an algebra problem, and we are expected to inequality for the volume of the aquarium.

Given that the

length= 2x

width=(x – 1)

heigth= (x + 2)

and the volume= 280 ft^3

the inequality expression for the volume is

$2x*(x -1) * (x + 2) \leq 280\\\\$

open the brackets

$2x*(x -1) * (x + 2) \leq 280\\\\(2x^2-2x)*(x+2)\leq 280\\\\\2x^3+4x^2-2x^2-4x\leq 280\\\\\2x^3+2x^2-4x\leq280$

divide through by 2 we have

$x^3+x^2-2x\leq140$
