Graphing is a good method when you have small integers or fractions as your slope.
Substitution is a good method when you have two equations, and when one of the coefficient of the variables is one.
Linear combinations is a good method when you have the same coefficient for the same variable in 2 different equations.
The fraction equal to 10/15 is 2/3
<u>10</u> /<u> 5 </u>=<u>2</u>
15 / 5 =3
Answer:
X = 3
Step-by-step explanation:
So do 7-2 which equals 5. 5 times 6 because 6 is outside of the parentheses with no symbol, so that means to multiply. That would equal 30. You want your answer to equal 6, so you would want the number inside of the parentheses to be 1, so that 1 times 6 would be 6. 2 x 3 would be sixe, and then 7-6 would equal one. 1 times 6 would be 6. So there is your answer.

Express as percentage
Hello!
If s(x) = x - 7 and t(x) = 4² - x + 3, find (t · s)(x) is also known as a composite function. (t · s)(x) is read as "t is composed of s", or "the composition of t and s".
(t · s)(x) = 4² -(x - 7) + 3
(t · s)(x) = 16 - x + 7 + 3
(t · s)(x) = -x + 16 + 7 + 3
(t · s)(x) = -x + 26
Therefore, (t · s)(x) = -x + 26.
