Answer:
-1 
Step-by-step explanation:
4x-8y=15
4x-8y-4x=15-4x
-8y=15-4x
-8y/-8=15-4x/-8
y=-1 7/8+1/2x
slope is -1 7/8
Answer:
$75.6
Step-by-step explanation:
Multiply the model car's price by 105% (or 1.05) to find the total price.
$72 * 105% = $75.6.
Step-by-step explanation:
If (5) = 3
Then (10) = 6
Because 5 x 2 = 10 so 3 x 2 = 6
Because two of the sides are identical in each triangle, that means the 3rd side would also be the same.
You could use the SSS Posulate only, since no angles are known.
