true or false: the points (6, 13), and (21, 33) and (99, 137) all lie on the same line. th equation of the lines is y + /3x + 5.

Phoenix [80]

Answer:

point A (6,13) lies on the equation. True

given point B(21,33) lies on the equation. True

given point C (99, 137) lies on the equation. True

The equation that was given was y = 4/3x + 5

Now,check the given equation for the given points.

1) A (6,13)

Substitute x = 6 in the given equation y = 4/3x +5

y = 4/3(6) + 5 = 4(2) + 5 = 8+5 = 13

y=13

the given point A (6,13) lies on the equation.

2) B (21,33)

Substitute x = 21 in the given equation y=4/3x+5

y=4/3(21) + 5 = 4(7) + 5=28+5=33

y = 33

the given point B(21,33) lies on the equation.

3) C (99, 137)

Substitute x = 99 in the given equation y = 4/3x + 5

y=4/3(99) + 5 = 4(33) + 5 = 132 + 5 = 137

y = 137

the given point C (99, 137) lies on the equation.

the formula P = 2l + 2w ives the promoter P of a rectangular room with length l and width w. A rectangular living room is 26 ft

jonny [76]

Answer:

Therefore the Perimeter of the room is 94 ft.

Step-by-step explanation:

Given:

$P=2l+2w$

Where ,

P = Perimeter

l = Length = 26 ft

w = Width = 21 ft

To Find:

Perimeter of the room = ?

Solution:

Perimeter of Rectangle is given as

$P=2l+2w$

Substituting 'l' and 'w' we get

$P=2\times 26+2\times 21=52+42=94\ ft$

$P=94\ ft$

Therefore the Perimeter of the room is 94 ft.

Find the measurement of X.

Sliva [168]

Since this is a scalene triangle, two sides will equal the same, meaning two angles will equal the same. So 70 has an equal on the other side, meaning 70+70=140, and x will equal the remainder, meaning x=40.

Hope that helps.
