Answer:
(6, 12)
Step-by-step explanation:
{ 3x - y = 6
{ x - 2y = -18
by using elimination:
6x -2y=12
x - 2y= -18
________-
5x = 30
x = 6
y = 18-6 = 12
the solutions = {(6, 12)}
Converse means switching the hypothesis and conclusion of a conditional statement. The converse of x > y, is y > x. Therefore, the answer to your question is y > x, switching the hypothesis and conclusion of the statement.
Answer:
use the reverse Pythagorean therm BC= 4 DE= 4.8
Step-by-step explanation:
The square root of 5(squared) - 3(squared) = 4
the square root of 8(squared) - 6.4(squared) = 4.8
I believe it is WW and WL for the top row and LW and LL for the second one. This kind of reminds me of punnett squares.
Answer:
This problem is about linear equations. We assume Dale drive X miles, and the total cost is $Y, then we can get:
Plan I: Y=38+0.11X
Plan II: Y=49+0.07X
When both plans cost the same, 38+0.11X=49+0.07X. We will get X = 275miles, and Y=$68.25
