<em>9</em><em>.</em><em>8</em><em> </em><em>+</em><em>12x</em><em>+</em><em>y-7</em>
<em>2</em><em>.</em><em>8</em><em>+</em><em>12x</em><em>+</em><em>4</em><em>y</em>
Consider this option:
1. area_rombus=a*h, where a=6 - the length of the side, h - height.
h=area_rombus/a.
2. area_sq=a², where a=6 - the length of the square.
area_sq=36, area_rombus=4/5 *36=28.8.
3. according to the item 1 h=area_rombus/a=28.8/6=4.8.
answer: 4.8
Answer:
x=16/13
y= -9/13
Step-by-step explanation:
A: -4y=-x+4
B: y+3x=3
4B: 4y+12x=12
A+4B: 12x= -x+16
-----> 13x=16
x=16/13
-4y= -16/13+4
4y=16/13-4
y=4/13-1= -9/13
Find slope
a. (-1,5) (0,0)
0-5/0+1
= -5
b. 4-3/4-3
=1
so a
