Answer:
X= 2 Y=5
Step-by-step explanation:
Set them equal
-2x+9=4x-3 add -2x to both sides and -3 to both sides
12=6x then divide by 6
x=2
plug in 2 to either equation and solve for Y.
Y=-2(2)+9
Y=5
First, you multiply 2.1 by 3.2, which gives you the answer of 6.72. Then, you multiply 10-2 by 10-4. One rule about multiplying exponents, you just add the exponents. So 10-2 x 10-4 = 10-6. Finally you get the answer of C. 6.72 x 10-6.
