Answer:
(1,1)
Step-by-step explanation:
we have
we know that
If a ordered pair is a solution of the inequality, then the ordered pair must satisfy the inequality
<u><em>Verify each ordered pair</em></u>
case A) we have
(5,0)
Substitute the value of x and y in the inequality
----> is not true
therefore
The ordered pair is not solution to the inequality
case B) we have
(0,-2)
Substitute the value of x and y in the inequality
----> is not true
therefore
The ordered pair is not solution to the inequality
case C) we have
(1,1)
Substitute the value of x and y in the inequality
----> is true
therefore
The ordered pair is a solution to the inequality
case D) we have
(-5,-6)
Substitute the value of x and y in the inequality
----> is not true
therefore
The ordered pair is not solution to the inequality
Answer:
B. f(x) domain: x ≥ 1; f⁻¹(x) range: y ≥ 1
Step-by-step explanation:
The <em>domain</em> of a function is identical to the <em>range</em> of its inverse. This is reflected in choices B and D. However, f(x) is undefined for x < 1, so it makes no sense to restrict its domain to x ≤ -2, as in choice D.
The appropriate response is ...
B.
- f(x) domain: x ≥ 1
- f⁻¹(x) range: y ≥ 1
Answer:
Find the perimeter first then the are
Step-by-step explanation:
A)
acd = a + b
(Get the value of B from image)
136 = a + 56
(Subtract 56 from both sides)
136 - 56 = a
(Solve 136 - 56)
a = 80
(C is supplementary with 136)
136 + c = 180
(Subtract 136 from both sides)
c = 180 - 136
(Solve 180 - 136)
c = 44
Therefore:
a = 80 and c = 44
B)
egh = e + f
(Get values from image)
63 = e + 23
(Subtract 23 from both sides)
63 - 23 = e
(Solve 63 - 23)
e = 40
(G is supplementary with 63, supplementary angles equal 180
63 + g = 180
(Subtract 63 from both sides)
g = 180 - 63
(Solve 180 - 63)
g = 117
Therefore
e = 40 and g = 117
