Answer:10+5=15 8+8= 16. 15+16=31
Step-by-step explanation:
31
Hi there!
Th' question asks :-
Which of the following lines is parallel to x = 4?
• 1ˢᵗ Option :-
=> y = 3 is [ Incorrect ]
• 2ⁿᵈ Option :-
=> y = 4 is [ Incorrect ]
• 3ʳᵈ Option :-
=> x = 2 is [ Correct ]
• 4ᵗʰ Option :-
=> x = y is [ Incorrect ]
EXPLANATION :-
→ Why 1ˢᵗ and 2ⁿᵈ Option are Wrong? :
X-axis and Y-axis are mutually perpendicular to each other.
Therefore, they can't be parallel.
→ Why 4ᵗʰ Option is Wrong? :
Th' value of X and Y is only same at the Origin ( 0, 0 )
Therefore, they can't be parallel.
→ Th' 3ʳᵈ Option is Correct, Cuz' X-axis is always parallel to itself.
In Short, x = 2 is th' Correct answer
~ Hope it helps!
The number of infected people will reach 568 in approximately 4 weeks
<h3>Linear equation and function</h3>
Exponential equations are inverse of logarithmic equation and are represented by the equation below:
y = ab^x
where
a is the base value and x is the exponent
Given the equation that shows the number of infected people from an outbreak of the measles as:
y = 4(6)^t
If the number of infected people reach 568, hence;
568 = 4(6)^t
568/4 = 4(6)^t/4
6^t = 568/4
6^t = 142
Take the natural logarithm of both sides
ln(6^t) = ln142
t = ln142/ln6
t = 4.37
Hence the number of infected people will reach 568 in approximately 4 weeks
