I typed it in a calculator and got 68,000,000, so just correct me if im wrong.
Answer:
13/7
Step-by-step explanation:
X + 1/7 = 2
X = 2- 1/7
x = 13/7
Answer:
a = - 
, b = - 
Step-by-step explanation:
To obtain the required form use the method of completing the square
add/ subtract ( half the coefficient of the x- term)² to x² - 9x
y = x² + 2(- )x + 
- + 14
= (x - )² - + 
= (x - )²- ← in the form (x + a)² + b
with a = - and b = -
Answer:
330
Step-by-step explanation:
Answer:
First expression 8y +4x +10
Second expression 7x-3y +6
If you want to combine both expressions: 5y +11x +16
Step-by-step explanation:
Like terms are the terms which have same variables and powers/roots.
Example: 7x and 2x are like terms because the variables are both "x". So we can combine in 9x
In an expression, only like terms can be combined. We combine like terms to shorten and simplify algebraic expressions, so we can work with them more easily. To combine like terms, we add the coefficients and keep the variables the same
10y + 3x + 10 + x -2y
10y-2y=8y 3x+x=4x
so 8y +4x +10
3x - y + 4x + 6 - 2y
3x+4x=7x -2y -y = -3y
so 7x-3y +6
