Answer:
a = 15
Step-by-step explanation:
g(x) is the same thing as "y". Our point gives us an x and y value, so we will sub those into the equation and solve for a:
-2 = a(1/3) - 7 and
-2 = 1/3a - 7 and
5 = 1/3a so
a = 15
Thank you for posting you question here at brainly. Below is the solution:
1/97 = 1 / (100-3) = 1 / (xo + dx)
<span>so, you have now that </span>
<span>x = xo + dx, where x = 97, xo = 100, and dx = - 3. Recognizing that 3 << 100, we can write the Taylor expansion around xo </span>
<span>1/ (xo + dx) ~ 1/xo + d/dx(1/xo)dx = 1/xo + (-1/xo^2)dx </span>
<span>= 1/100 - (1/100^2) (-3) = 1/100 + 3/100^2 </span>
<span>= 1/100 + 3/10000 </span>
<span>= 0.01 + 0.0003 </span>
<span>= 0.0103 </span>
Answer:
Let x represent the amount of weeks she is saving up for the bike, and y represents the cost of the bike.
The equation would look like this:
So, let's say the bike costs $2000.
Divide 2000 by 20, and it will give you the x value (or, the amount of weeks it will take)
It will take 100 weeks for her to save $2000 for the bike, if she puts back $20 each week.
Answer:
g = - 5
Step-by-step explanation:
2 - 8g = -3 - 9g
Add 9g to both sides of the equation:
2 - 8g + 9g = -3 - 9g + 9g
2 + 1g = - 3
Subtract 2 from both sides of the equation:
2 - 1g - 2 = - 3 - 2
1g = -5
Divide both sides of the equation by 1:
g = -5
