x∈ R
}
Step-by-step explanation: Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.
Answer:
See below.
Step-by-step explanation:
You have already drawn the line x = -1 . This is the vertical line passing through the point F.
So if we reflect across this line, F will stay where it is at (-1,-1) (because F is on the 'mirror'). E is 3 units in front of the line so is reflected 3 units the other side.
The image of E, E' will be at (2, -3). The image of G, G' will be at (-2,-3).
Answer:
k=2
Step-by-step explanation:
7[k+8]=70
First distribute the 7 into the k+8
7k+56=70
Then subtract the 56 on both sides since we want to isolate the variable
7k=14
Lastly divide each side by 7 to get the variable by itself and its value
k=2
We can check this by plugging 2 into the equation. We substitute for 2 in place of k.
7[2+8]=70
First do inside the brackets
7[10]=70
Next multiply
70=70
The equation is true so we know for sure that 2=k
Answer:
If your looking for #11 I think the answers -5
Step-by-step explanation:
Let A unit be a; B unit be b
a + b = 95
b = 95 - a
3a + 5b = 395
3a + 5(95 -a) = 395
3a + 475 - 5a = 395
-2a = -80
a = 40
a + b = 95
40 + b = 95
b = 55
Therefore, a = 40; b = 55.
Hope this helps
