What is the value of this expression when a = 2 and b = -3 ? a^3 - b^3 / 5

Mathematics

Answer:

13 2/5

Step-by-step explanation:

a = 2 and b = -3

so the question asks whats.... a^3 - b^3/5

First we plug in the values of a and b

(2)^3 - (-3)^3 /5

Now we solve the ones in paranthesis first

(2)^3 = 8 because 2×2×2 and

-(-3)^3 forget about the - outside the parenthesis so

(-3)^3 = (-27) because (-3)×(-3)×(-3)

now we put it back together

8 -(-27)/5

the two minus become plus so

8 + 27/5

Now we solve it like fractions

8 and 27/5

simplify

13 and 2/5

Hope that helps!

Which property is shown? 4/5+ -<br> 4/5=0
TEA [102]
This looks like the additive inverse property, because when you add something to its negative counterpart (or its additive inverse), you get 0 as a sum.

Another example would be 2+ (-2) = 0. -2 is the additive inverse for 2.

3. Write the following equation in slope intercept form: -2x + y = 9 A.) Y = -2x + 9 B.) Y = -2x – 9 C.) Y = 2x + 9 D.) Y = 2x –
Ira Lisetskai [31]

Hey! :)

So when we write something in slope intercept form, all we're doing is solving for y. So let's do that with this equation!

-2x + y = 9

add 2x to both sides

y = 2x + 9

So C is your answer.

Please let me know if you need anything further explained!
