Answer:
(a) f(x) = √x -2
Step-by-step explanation:
The square root function has no horizontal shift, so the expression under the radical is simply x with no added terms. There is only one such answer choice, which also shows the necessary translation downward by an added negative constant.

Answer:
The slope of the line is 1
Step-by-step explanation:
the formula for slope is
y¹-y²
-----
x¹-x²
y¹ and x¹ can be either of the points.
So let's make it (6,5)
This means that y² and x² will be (8,7)
The equation will be
5-7d -2
----- = ---
6-8 -2
which can be simplified to 1 by divied both by -2
Answer:
Step-by-step explanation:
If Lois is 4 times as old as her son and we don't know how old the son is, the son's age is x and his mother's age is 4x (4 times the son's age). The word sum means to add, so the equation for this is
x + 4x = 40
Answer:
The scale of the map is 1 inch is <u>15 miles.</u>
Step-by-step explanation:
Given:
Distance of neighboring towns on map = 2.4 inches
Actual Distance of neighboring towns = 36 miles.
We need to find the scale of map;
Solution:
Now we know that;
On map 2.4 inches = 36 miles actual distance.
So on map 1 inch = Actual distance in 1 inch of scaling on map.
By using Unitary method we get;
Actual distance in 1 inch of scaling on map = 
Hence The scale of the map is 1 inch is <u>15 miles.</u>
