Answer:
0.575
Step-by-step explanation:
I divided 3÷8 and got 0.375 to get the decimal of the fraction. Then since there is a subtraction and negative sign they cancel out to a positive where I added the 0.2 to 0.375 and got that as my answer.
X-y=5
xy=3.36
add y to both sides on first
x=5+y
sub that in other eqation
(5+y)y=3.36
expand
y^2+5y=3.36
minus 3.36 both sides
y^2+5y-3.36=0
use quadratic formula
for
ay^2+by+c=0

for 1y^2+5y-3.36




y=-2.5+/-3.1
y=5.6 or 0.6
sub back
x=y+5
so
x=10.6 or 5.6
the numbers are either 10.6 and 5.6 or 0.6 and 5.6
wait,but 10.6 and 5.6 don't multiply to get 3.36 so that is an extrainiesous answer
answer is 0.6 and 5.6
Answer:
63/9=7
6.3/0.9=7
0.63/0.09 = 7
Step-by-step explanation:
Notice that x remains x, so the translation is not right or left.
y becomes y + 3. You add 3 to each y-coordinate, so the translation is 3 units up.
