What is the rule for Aaliyah’s machine? Try to write the rule as an equation.
Eva8 [605]

Answer:

  f(x) = 2x +1

Step-by-step explanation:

Apparently the ordered pairs are ...

  (x, f(x)) = (1, 3), (2, 5), (3, 7), (4, 9)

We note that as x increases by 1, the value of f(x) increases by 2. The difference between f(x) and 2x is 3-2·1 = 1, so we have ...

  f(x) -2x = 1

  f(x) = 2x +1 . . . . . . add 2x

Find the equation of the linear function 'g' going through (20,5) and (-5,-8). Use 'u' for your input variable.
frosja888 [35]

Answer:

  • See below

Step-by-step explanation:

<u>Use the slope-intercept form, which will be in this case:</u>

  • g(u) = mu + b, where m is the slope, b is the y- intercept

<u>Find the slope:</u>

  • m=(y_2-y_1)/(x_2-x_1)
  • m=(-8-5)/(-5-20)=(-13)/(-25)=13/25

<u>Find the value of the y-intercept:</u>

  • 5=1/25*20+b
  • b=5-4/5=21/5

<u>The equation is:</u>

  • g(u)=\frac{13}{25} u+\frac{21}{5}

aleksklad [387]
<span>let the angles be x and y.
as they are compliment
x+y=90 
also given
x=7y 

substituting value of x in first equation
7y+y=90
8y=90 
therefore 
y=11.25
x=7*y=78.75</span>

Help me solve this please ill give good rating...
blagie [28]

Answer: For the first part, her total savings would be $88, and for the second part, (let's pretend s = the total savings) the equation would be s = 40 + w x 6.

Step-by-step explanation: As for the first part, we would need to multiply her money per week times the amount of weeks she works. We can do this by simply multiplying the amount she makes (6) by the amount of weeks she works (8), resulting in 48, but we still have to add that number to the amount she already has, or 40, making $88 in total, as for the second part, this does a great job of explaining the reasoning behind that as well. Hope this answered your question!
