He equation y equals 4 times 6 to the power of t shows the number of infected people from an outbreak of the measles. The variab

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

One number is 2 more than 3 times another. their sum is 22. find the numbers. 8, 14
bija089 [108]
X + y = 22
x = 3y + 2

3y + 2 + y = 22
4y + 2 = 22
4y = 22 - 2
4y = 20
y = 20/4
y = 5

x = 3y + 2 = 3(5) + 2 = 15 + 2 = 17

ur numbers are 5 and 17
