Answer:
6√2
Step-by-step explanation:
from the graph the coordinates of the points are (2, 5) and (- 4, -1)
the distance is d= √(x2-x1)²+(y2-y1)² = √(-4-2)²+(-1-5)²=√72 = √2*2*2*3*3= 6√2
Answer:
From -6 to positive 1 the length is 7
Step-by-step explanation:
you still add'em.
Answer:
To use the elimination method one coefficient of either x or y must be the same number with opposite signs, so the ordered pair is (-10, -8)
Step-by-step explanation:
2(-x+y=2) Make one of the coefficients equal, with opposite signs.
2x-3y=4 Combine equations.
-y=8 Solve, y=-8
Then find x, -x-8=2
-x=10, so x= -10
(-10, -8) is your answer.
Answer:
x = 3t, y = t + 2
Draw a straight line connecting:
(0,2) and (2,-6)
Step-by-step explanation:
- 6x + 18y = 36
18y = 6x + 36
3y = x + 6
y = x/3 + 2
Let x = 3t
Then y = t + 2
Graph:
y = x/3 + 2
Intercepts
x-intercept:
0 = x/3 + 2
x/3 = -2
x = -6
y-intercept:
y = 0 + 2
y = 2
Draw a straight line connecting:
(0,2) and (2,-6)
