3.5x-10>-3 add 10 to both sides
3.5x>13 divide both sides by 3.5
x>26/7
x=(26/7, +oo)
...
8x-9<39 add 9 to both sides
8x<48 divide both sides by 8
x<6
x=(-oo,6)
Since this is a compound inequality with AND the solution set will be the union of the two intervals found above.
x=(26/7, 6)
Answer:
y=4
Step-by-step explanation:
it has only one solution.
Given:
Side length of base = 8
Slant height = 6
To find:
The surface area of the square pyramid.
Solution:
Surface area:

where A is the area of base
p is the perimeter of base
s is the slant height
Area of base (A) = 8 × 8
= 64
Perimeter of base(P) = 4 × 8
= 32
Substitute these in the formula:



The surface area of the square pyramid is 160 unit².
A.Yes a function as a vertical line crosses the curve at one point only.
B.the domain is [-4,3]
C. the range is [-3,3]
D. it's -3
