Find an x value and f(x) is just it's y value. we can start with x=0
when x=0 y= -3
when x= 2 y= -2
and so on, choose easy to read numbers.
you can finish the rest, let me know if you wanna check your answers or if you are stuck.
Answer:
6.5 x 10^6 To answer this question, you need to divide the mass of the sun by the mass of mercury. So 2.13525 x 10^30 / 3.285 x 10^23 = ? To do the division, divide the mantissas in the normal fashion 2.13525 / 3.285 = 0.65 And subtract the exponents. 30 - 23 = 7 So you get 0.65 x 10^7 Unless the mantissa is zero, the mantissa must be greater than or equal to 0 and less than 10. So multiply the mantissa by 10 and then subtract 1 from the exponent, giving 6.5 x 10^6 So the sun is 6.5 x 10^6 times as massive as mercury.

Answer: x=2
Step-by-step explanation:
first subtract 3x from both sides
then your equation will be 8x-7=9 then you will add 7 to both sides getting 8x=16 then divide both sides by 8 and x=2
Answer:
0.35 Gallons.
Step-by-step explanation:
Since there is already 9/10 in it, you can only pour 1/10 in now. 1/10th of 3.5 is 0.35.
