Answer:

False

Step-by-step explanation:

A parallelogram has 2 pairs of opposite side that are parallel

A parallelogram also has opposite angles that are equal

But any polygon is the key term

It can have more than 4 sides.

An example would be an octagon

It has 4 pairs of parallel sides

What is the equation of the line that is parallel to y=x+4 and that passes through (5,–4)?
antiseptic1488 [7]

Answer:

y = \frac{1}{5} x - 5

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = \frac{1}{5} x + 4 ← is in slope- intercept form

with slope m = \frac{1}{5}

• Parallel lines have equal slopes , then

y = \frac{1}{5} x + c ← is the partial equation

to find c substitute (5, - 4 ) into the partial equation

- 4 = 1 + c ⇒ c = - 4 - 1 = - 5

y = \frac{1}{5} x - 5 ← equation of parallel line

Write an equation that is perpendicular to x-3y=2 and contains the point (2,4)
Kisachek [45]

perp to x-3y=2 thru (2,4)

For perpendicular we swap the coefficients on x and y, negating one

3x + y = some constant

We get the constant in the obvious way from the point

3x + y = 3(2) + 4 = 6 + 4 = 10

Answer: 3x + y = 10

What is the diameter of a circle with a circumference of 220 ft
tino4ka555 [31]

Circumference of the circle is given as = 220 feet

We have to find the diameter.

Circumference is found as = 2 * PI * r

220=2*3.14*r

220=6.28r

r=35.03

Diameter is 2*radius

Diameter = 2\times35.03 = 70.06

Hence, diameter of the circle is 70.06 feet.

3x+y=-4<br> 3x-4y=6<br><br> Solve the simultaneous equation
Nezavi [6.7K]

Good morning ☕️

Answer:

(\frac{-2}{3} , -2)

Step-by-step explanation:

3x+y=-4   (1)

3x-4y=6  (2)

<em><u>solving by elimination:</u></em>

(1) - (2) ⇒

3x + y  = -4

3x - 4y = 6

________

0 + 5y  = -10

5y = -10 ⇔ y = -2

(2) ⇒ 3x-4y=6  ⇒ 3x-4(-2)=6  ⇒ 3x = 6 - 8 = -2 ⇒ x = -2/3
