Answer:
(1,4)
Step-by-step explanation:
2x-3y=-10
y=4x
Since the y is already isolated, you can use substitution to find the answer to this equation. Simply replace any y values in the first equation with 4x:
2x-3(4x)=-10
2x-12x=-10
-10x=-10
x=1
y=4(1)=4

Answer:
Choice D
Step-by-step explanation:
(9.1 x 10^5) - (9.3 x 10^4)
910000 - 93000 = 817,000 = 8.17 x 10^5
usually, you would want <u>a whole number</u> in standard notation
A. 0.817 x 10^6 = 817,000
B. 817 x 10^3 = 817,000
C. 8.17 x 10^4 = 81,700
D. 8.17 x 10^5 = 817,000
