Does it have multiple choice?
If it does not i can give you my answer but idk how they want it to be written or to be simplified.
Answer:
B
Step-by-step explanation:
The problem is simple because they use powers of 10. When something is multiplied by a power of ten, it is essentially moving the decimal point over for every power.
9.46x10^12= 9460000000000
4.0x10^13= 40000000000000
Although 4 itself is less than 9.46, since is is being multiplied by 10^13, it will be one decimal place bigger.
Plug (-6,-5) into the equations to see wich one fits.
y=9/2 x +22
(-5)=9/2(-6) +22
-5=9*-3+22
-5=-27+22
-5=-5
that's how B is the answer. hope this helps :)
y = 4
first note that the right side simplifies to 12, equation can be written
= 12 ( multiply both sides by 0.8 )
2y + 1.6 = 9.6 ( subtract 1.6 from both sides )
2y = 8 ( divide both sides by 2 )
y = 4
