Answer:↓↓↓
Step-by-step explanation:
We are given that side AB is congruent to <u>BD</u>. We are also given that side AC is congruent to <u>CD</u>.
We know that side BC and side <u>CB</u> are congruent because of the <u>Reflexive</u> property.
Therefore, ΔABC and Δ<u>DBC</u> are congruent because of <u>SSS Postulate</u>.
Hope this helped!
Answer:
x=-29/24
y=3/8
Step-by-step explanation:
3x-9y= -7 ---A
2y-6x= 8----B
multiply eq A by 2
6x-18y=-14
-6x+2y=8
Add both equations, so you eliminate x since 6x+(-6x) = 0
-18y+2y= -16y
-14+8=-6
so you have
-16y=-6
y=3/8
now substitute this back to eq B, (you can use eq A as well if you like)
2(3/8)-6x=8
3/4-6x=8
-6x=29/4
x=-29/24
