Hello :
equation of <span>If a line contains the point (0, -1) and has a slope of 2
is ; y+1 = 2(x-0)
y = 2x-1
when =1 y = 1
the point </span><span>(1, 1)is un the line.</span>
Step-by-step explanation:
Flour needed to make birthday cakes = 2x
Flour needed to make holiday cakes = 1y = y
Maximum amount of Flour allowed = 20 (No more than 20)
Therefore
2x + y must not be more than 20

Answer:
The solution of the equation is
⇒ 3rd answer
Step-by-step explanation:
* Lets explain how to solve this problem
- The function f(x) = e^x is called the (natural) exponential function
- The natural logarithm (㏑), or logarithm to base e, is the inverse
function to the natural exponential function
∵
is an exponential function
∴ We can solve it by using the inverse of e (㏑)
- Remember:
# 
# 
- Insert ln in both sides
∴ 
∵ 
∴ 2x + 5 = ㏑(4)
- Subtract 5 from both sides
∴ 2x = ㏑(4) - 5
- Divide both sides by 2 to find x
∴ 
* The solution of the equation is 
Is this math? if so let me know maybe I could try to help
