Answer:
Domain and range are the set of all real numbers.
Step-by-step explanation:
Given that Ann thought of a number N, multiplied it by 5 and added 7. Then she told the result R to Jim
Here no restriction is mentioned for the number N.
It can be any number but real.
Hence we can say that domain is the set of all real numbers
For range let us calculate y for any x
If Ann thought of x as the number then
she would multiply by 5 to get 5x and add 7 to get 5x+7
Hence y =5x+7
Since y has no exception here range can also be the set of all real numbers
The equation of the line is y = -7. If the slope is zero, the line is flat.

Hey there!
The first graph is the correct answer. A point on the parabola is equally far from the focus as it is to the directrix.
Let me know if this helps :)
Answer:
D. 6 + 6 + 30 + 40 + 50 = 132
Surface area of triangular prism:
(perimeter of base) × length + base × height
(s₁ + s₂ + s₃)(l) + bh
Here, provided with:
So, the surface area:
Only option D gives 132 as an answer which is equivalent to the area.
