Answer:

See below.

Step-by-step explanation:

OB = OA + AB

AB = OB - OA

=  4x + 8y - (2x + 9y)

= 2x - y

CD = 4x - 2y

= 2(2x - y)

Therefore  the vector CD has the same direction as AB (its the same line on the coordinate plane) but  has  twice the magnitude of AB. That is its represented by a line  twice as long.).

Blizzard [7]

Complete Question

Consider the isosceles triangle. left side (2z+8)units, bottom of triangle (4z-10)units, right side of triangle (2z+8) units Part A Which expression represents the perimeter of the triangle? a.(4z+16) units b.(6z−2)units c.(8z−16) units d.(8z+6) units

Answer:

d. (8z + 6) units

Step-by-step explanation:

The formula for the Perimeter of a Triangle is :Side A + Side B + Side C

Hence,

(2z + 8)units + (4z - 10) units + (2z + 8)units

= (2z + 8 + 4z - 10 + 2z + 8)units

Collect like terms

= 2z + 4z + 2z + 8 - 10 + 8

= 8z + 6 units

The expression that represents the perimeter of the triangle is (8z +6) units

Are the graphs of the lines in the pair parallel? Explain. y = 6x + 9 27x – 3y = –81
olga nikolaevna [1]
For the 2nd equation, you need solve for y to get it by itself so once thats done you get y=9x+27 but since the x values (also the slope) aren't equal, they can't be parallel
