The answer would be -14 because 9-23=14

To check, subtract 23 from 9, and then add 23 back. :3

If x +23 = 9, then, x = 9-23.

So x = -14

Use the graphs to solve the simultaneous linear equations
Delicious77 [7]

Answer:

x = 2 and y = 5

Step-by-step explanation:

Given the simultaneous linear equations

y = 2x + 1 and x + y = 7

We are to find the  value of x and y;

Substitute 1 into 2

From 2;

x+y = 7

x+2x+1 = 7

3x+1 = 7

3x = 7-1

3x = 6

x = 6/3

x = 2

Recall that y = 2x+1

y = 2(2) + 1

y = 4+1

y = 5

Hence the solution from the graph will be the point where the line cuts the x axis and this will be at x = 2 and y = 5

Describe the steps you would take to solve for the variable x in the following
adoni [48]

Answer:

x =  19

Step-by-step explanation:

1. add 31 on both sides (you wanna get the "x" by itself)

ex: 2x - 31 = 7

          +31   +31

2. the 31s cancel each other out so now you add 31 + 7

2x       =  7

           +31

___________

             38

3. divide 2 on both sides so the 2s cancel each other out and only the x is left

ex: 2x / 2 = x         38 ( the 38 stands alone)

4. now divide 38/2 and you have your answer

X= 19

A population of 200 animals has a growth rate of 1.03% each year. at this growth rate, the function f(x)=200(1.03)^x gives the p
Y_Kistochka [10]
For this case, the first thing we should do is use the following equation:
 f (x) = 200 (1.03) ^ x
 We substitute f (x) = 300:
 300 = 200 (1.03) ^ x
 We clear the value of x:
 log1.03 (300/200) = log1.03 ((1.03) ^ x)
 x = log1.03 (300/200)
 x = 13.72
 Answer: 
 the population will first reach 300 in about 13.72 years.
