for the equation x + y = 3. How many possible values for x are there if x and y are both whole numbers?

A.2
B.3
C.4

Answers

Answer:

A

Step-by-step explanation:

Because it is 2+1 and 3+0, those are the only solution, therefore A is correct

Answer: C) 4

======================================================

Explanation:

The set of whole numbers is {0, 1, 2, 3, ...}

So we include 0 and any positive number that doesn't have decimal or fractional components to it. Negative values are not included.

If we plug in x = 0, then x+y = 3 solves to y = 3If we plug in x = 1, then x+y = 3 solves to y = 2If we try x = 2, then x+y = 3 solves to y = 1Lastly, x = 3 leads to y = 0

Whatever you pick for x, the y value must add to it to get 3. Both x and y must be numbers from the set of whole numbers.

There are four cases shown in the bullet points above, so we have four different solutions. We can't move onto x = 4 because the y solution would be y = -1, but -1 is not in the set of whole numbers.

Simplify Using Distributive Property
-6(2a + 8)

Answers

Answer:

-12a - 48

Step-by-step explanation:

you do -6 times 2a which is -12a then you do -6 times 8 which gives you -48 so you put -12a - 48

since the 48 is a negative we would just put a minus sign instead a plus. If it was a positive 48 we would put a plus sign buts its not so we put a negative.

[tex]\huge\boxed{\mathcal{HELLO!}}[/tex]

The distributive property states that

a(b+c)=ab+ac (we multiply a by everything inside the parentheses)

-6(2a+8)

-12a-48

Answer:

[tex]g^{-1}[/tex] (x) = 8x + 48

Step-by-step explanation:

let y = g(x) and rearrange making x the subject, that is

y = [tex]\frac{x}{8}[/tex] - 6 ( add 6 to both sides )

y + 6 = [tex]\frac{x}{8}[/tex] ( multiply both sides by 8 )

8(y + 6) = x , distribute

8y + 48 = x

Change y back into terms of x with x = [tex]g^{-1}[/tex] (x) , thus

[tex]g^{-1}[/tex] (x) = 8x + 48

Answer: x = 23

∠DBC = 23°

∠ABC = 157°

Step-by-step explanation: A straight line is 180°, which means that ∠DBC and ∠ABC must equal 180°.

180 - 19 = 161

23 × 6 = 138

138 + 23 = 161

If x = 23°, then ∠DBC is 23°.

For ∠ABC, (6(x) + 19°

6(23) + 19°

6 × 23 = 138

138 + 19 = 157

∠ABC = 157°
