Step-by-step explanation:
5x+7+2x=7(2x+3)-63
We move all terms to the left:
5x+7+2x-(7(2x+3)-63)=0
We add all the numbers together, and all the variables
7x-(7(2x+3)-63)+7=0
We calculate terms in parentheses: -(7(2x+3)-63), so:
7(2x+3)-63
We multiply parentheses
14x+21-63
We add all the numbers together, and all the variables
14x-42
Back to the equation:
-(14x-42)
We get rid of parentheses
7x-14x+42+7=0
We add all the numbers together, and all the variables
-7x+49=0
We move all terms containing x to the left, all other terms to the right
-7x=-49
x=-49/-7
x=+7 - Answer
The answer is the third option with 2/3 as the slope.
Hope I didn't mess up for your sake!
sorry i dont have answered
Answer
p(t) = 20,000^10 root of 2^t/10 root of 2^7. i think
Step-by-step explanation:
Algebra is the part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formula and equations.
Equation examples:
· Slope intercept form: y = mx+b, where m is the slope and b is the y-intercept.
· Point slope form: <span>y - k = m(x - h)
</span>· <span>Pythagorean theorem: a</span>² + b² = c²
