Answer:
Domain: [-3, 2]
Range: [-3, 3]
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
Range is the set of y-values that are outputted by function f(x).
We see that our x-values span from -3 to 2. Since they are both closed dots, they are included in the domain:
[-3, 2] or -3 ≤ x ≤ 2
We see that our y-values span form -3 to 3. Since they are both closed dots, they are included in the range:
[-3, 3] or -3 ≤ x ≤ 3

for the equation x + y = 3. How many possible values for x are there if x and y are both whole numbers?
A.2

Answers
Answer:
A
Step-by-step explanation:
Because it is 2+1 and 3+0, those are the only solution, therefore A is correct
======================================================
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 = 0Whatever 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.

Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
M=14
Step-by-step explanation:
So distribute first
9m-27+3m=7m+43
Combine like Terms
12m-27=7m+43
Subtract 7m on both Sides
5m-27=43
Add 27 on both sides
5m=70
Iso,ate variable by dividing 5 on both sides

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°

-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)
