What is the value of 9(n+2)−5n for n=14? 3 9 10 19

Murrr4er [49]

If you want to know the value of a function, you need to substitute the variable (here n) for the value:

so in the function

9(n+2)−5n

we substitute n with 14:

9(14+2)−5*14

first calculate the inside of the bracket:


9*16−5*14

9 times 16 is 144

144-5*14

5*14 is 70, so we have

144-70=74

so the answer should actually be 74!

Perhaps you mistyped the questions? can you check it again, please?

Dario buys applesauce for a family reunion. He needs 23 cups, and he buys them in packs of 6. How many packs does Dario need?

hodyreva [135]

He has to buy 4 packs. If you divide 23 by 6, you get 3.833 but you can’t buy a fraction of a pack so you have to round up and buy 4 packs. Hope this made sense; I can explain further if needed!

Multiply. (v+8)(v-8) simplify

san4es73 [151]

V * v = v^2
v * -8 = -8v
8 * v = 8v
8 * -8 = -64

v^2 - 8v + 8v - 64
v^2 - 64

This was using the distributive property or using the FOIL method

The slope of a line passing through H (-2, 5) is -3/4. Which ordered pair represents a point on this line?

oksano4ka [1.4K]

Answer:
(6,-1)

Explanation:
The slope of the line can be calculated using the following formula:
slope = $\frac{y2-y1}{x2-x1}$

We are given that:
slope = -0.75
point (x1,y1) is (-2,5)

We will use each of the given points to calculate the corresponding slope, then compare the calculated slope with the given one.

For point (6,-1):
slope = $\frac{-1-5}{6--2}$ = -0.75 ........> accepted choice

For point (2,8):
slope = $\frac{8-5}{2--2}$ = 0.75 ........> rejected choice

For point (-5,1):
slope = $\frac{1-5}{-5--2}$ = 4/3 ........> rejected choice

For point (1,1):
slope = $\frac{1-5}{1--2}$ = -4/3 ........> rejected choice

Therefore, the first option is the only correct one.

Hope this helps :)
