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

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.
