What is an equation in point-slope form of the line that passes through (1, -6) and (4, 6)?
Nadya [2.5K]

Answer:

See below.

Step-by-step explanation:

The point=slope form is: y-y_{1}=m(x-x_{1}), where m is the slope.

First, find the slope using to two given points.

m=\frac{\Delta y}{\Delta x} =\frac{6-(-6)}{4-1} =\frac{12}{3}=4

We can now plug in the numbers. You can pick any of the two points to use.

Version 1:

y-(-6)=4(x-(1))

y+6=4(x-1)

Version 2:

y-(6)=4(x-4)

y-6=4(x-4)

If desired, you can simplify this further.

Write an inequality for x that would give this rectangle a perimeter of at least 300ft
Travka [436]

Answer:

The inequality for x is:

x\geq 142

Step-by-step explanation:

Given:

Width of rectangle = 3 ft

Height or length of rectangle = (x+5) ft

Perimeter is at least 300 ft

To write an inequality for x.

Solution:

Perimeter of a rectangle is given as:

⇒ 2l+2w

where l represents length of the rectangle and w represents the width of the rectangle.

Plugging in the given values in the formula, the perimeter can be given as:

⇒ 2(x+5)+2(3)

Using distribution:

⇒ 2x+10+6

Simplifying.

⇒ 2x+16

The perimeter is at lest 300 ft. So, the inequality can be given as:

⇒ 2x+16\geq 300

Solving for x

Subtracting both sides by 16.

⇒ 2x+16-16\geq 300-16

⇒ 2x\geq284

Dividing both sides by 2.

⇒ \frac{2x}{2}\geq \frac{284}{2}

⇒ x\geq 142   (Answer)
