Answer : x = 25
5 x=32−7
5 x = 25
25x = 625
x=625/25
x=25

Answer:
a. (2+3)×4²+1=81
b. (2+3)×(4²+1)=85
c. 2+(3×4²)+1=51
d. 2+3×(4²+1)=53
Step-by-step explanation:
a. Parentheses about the 2 + 3 - then use PEMDAS to give 5 * 16.
b Inserting 2 parentheses makes it 5 * 17 = 85.
c.Inserting the parentheses simplifies it to 2 + 48 + 1 = 51.
d. Inserting the parentheses makes it 2 + 3*17 = 53
The system of equations:2 y = - x - 12 y = x + 5---------------------- x - 1 = x + 5- 2 x = 5 + 1- 2 x = 6x = - 6 : 2x = - 32 y = - 3 + 52 y = 2y = 1The solution is ( - 3 , 1 ).Answer: The x-coordinate of the solution to the system is: x = - 3.

Answer:
The solution is possible
Step-by-step explanation:
Given
Required
Is an output of 200, possible?
To know if it is possible or not, we start by substituting 200 for f(x)
Divide both sides by 5
Take logarithm of both sides
Apply law of logarithm
Divide both sides by log2
for f(x) = 200, x is approximately 5.32
Hence, the solution is possible
Answer:
no solutions
Step-by-step explanation:
5 -2 sqrt(x) = 11
Subtract 5 from each side
5- 5 -2 sqrt(x) = 11-5
-2 sqrt (x) = 6
Divide each side by -2
-2/-2 sqrt(x) = 6/-2
sqrt(x) = -3
The sqrt(x) must be 0 or positive
