Consider the system of equations. x−2y=4 2x+y=5 Which system has the same solutions as the system of equations? x−2y=4 6x−3y=−15 x − − 2 y = 4 6 x − − 3 y = − − 15 x−2y=4 6x−3y=15 x − − 2 y = 4 6 x − − 3 y = 15 x−2y=4 6x+3y=−15 x − − 2 y = 4 6 x + 3 y = − − 15 x−2y=4 6x+3y=15 x − − 2 y = 4 6 x + 3 y = 15

correct answer is b. 27/8

step-by-step explanation:

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²

it is definatly the 3rd one. very much looks like it, for a good chance, the third one would be best for you.

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
