x+19= 26
x+19-19= 26-19
x= 7
Check answer by using substitution method
x+19= 26
7+19= 26
26= 26
Answer is x= 7 (D.)
Exercise 1:
The exponents are wrong: when you divide two power, you subtract the exponents:

Exercise 2:
The function represents a growth rate of 300%! 3% is actually written as 0.03, so the correct function is

Exercise 3:
To factor a quadratic equation, we have to find the roots. Once you have the roots
, you can factor the expression as 
In this case, the solutions are
, which yields the factorization

Exercise 4:
When you multiply two powers of the same base, you add the exponents:

So, in your case, you have

Answer:
12
Step-by-step explanation:
Here we use SOHCAHTOA
Seeing as we have the hypotenuse and we are working to find out the opposite, we use SOH
Sin(x)= Opposite/Hypotenuse
Sin(45) = x/
×12 root 2
sin(45) times 12 root 2= 12
x=12

Step-by-step explanation:
A slope of -3/5 means the line drops 3 units for each 5 units it goes to the right. Then you can find another point on the line by going 5 uints to the left (to x=-2) and 3 units up (to y=1).
Plot the given point and the one just computed and draw the line through them.
