(Will give Brainliest) Explain what the graph of the function represents. Be sure to use complete sentences.
Irina-Kira [14]

Answer: f(-735) = -\frac{2}{3}(-735) + 490 = 980

Step-by-step explanation:

f(x) = -\frac{2}{3} x + 490 =0  Subtract 490 from both sides

        \frac{3}{2}* -\frac{2}{3} x = -490 *\frac{3}{2}   Then flip -\frac{2}{3} multiply both sides by \frac{3}{2} to cancel out -\frac{2}{3}

      x= -735  Thus giving you -735 as your x.

Then you plug it back into the equation to solve.

Nina has some nickels and 9 pennies in her pocket. Her friend, Maurice has twice as many nickels as Nina. Together these coins a
algol13

So Maurice would have 2N nickels  

Total number of coins is N + 2N + 9 = 3N + 9  

Each nickel is 5 pennies  

3N of nickels = 15N pennies  

-----------  

Their worth is 84 cents  

15N + 9 = 84  

15N = 75  

N = 75/15 = 5  

N = 5  


This means Nina has 5 nickels.

You do not need to flip the inequality sign when solving the inequality -3 t + 7 ≥ 9.
NemiM [27]

For this case we must resolve the following inequality:

-3t + 7 \geq9

Subtracting 7 from both sides of the inequality we have:

-3t \geq9-7\\-3t \geq2

Dividing by 3 to both sides of the inequality we have:

-t \geq \frac {2} {3}

We multiply by -1 on both sides, taking into account that the sense of inequality changes:

t \leq- \frac {2} {3}

Thus, it is observed that to solve the inequality it is necessary to change the meaning of it.

ANswer:

False. It is necessary to change the sense of inequality

Ne4ueva [31]

Answer:

The greatest number of arrangements possible would be 5

Step-by-step explanation:

If we look at the x values (in this case # of tulips remaining) we can find the number 20. And we see that there is a line going through it. We then stop at the point and go down to see what number it would fall on on the y axis.
