Answer:
y = 5
Step-by-step explanation:
Expand the logarithm:
_____
You can also take the antilog first:
5y = y²
y(y -5) = 0 . . . . . subtract 5y, factor
y = 0 or 5 . . . . . y=0 is not a viable solution, so y=5.
Answer:
Let x be the percentage score he got in fifth test,
According to the question,
His score in first, second, third and fourth test are 80%, 84%, 76% and 77% respectively,
Thus, the average of his total score in the five test,
= 
But, Again according to the question,
The average of the five grades as greater than or equal to 80%
That is,
⇒ 
⇒ 
⇒ 
Thus, the least score he can get in the fifth test is 83.
No x-intercept/zero
Step by step
To find x-intercept/zero, substitute f(x)=0
F(x)=-20
0=-20
The statement is false for any value of
X=0
Since there is no solution for f(x)=0, there is no -intercept/Zero

Answer: 24 and 37
Step-by-step explanation:
Let the numbers be x and y . Also let us pick x as the larger number.
From the first statement :
x + y = 61 ............................ equation 1
From the second statement :
x = y + 13 ............................equation 2
Solving the resulting linear equations by substitution method, substitute x = y + 13 into equation 1, then
x + y = 61 becomes
y + 13 + y = 61
2y + 13 = 61
2y = 48
y = 24
Substitute y = 24 into equation 2 , then
x = y + 3 becomes
x = 24 + 13
x = 37
Therefore the numbers are 24 and 37
