The answer is: Substitution property of equality.
The explanation is shown below:
1. To solve this problem you must apply the proccedure shown below:
2. When you clear the variable x from the first equation, and subtitute it into the second equation, you obtain:
<span>3x−2y=10
x=(10+2y)/3
4x−3y=14
</span>4[(10+2y)/]−3y=14
<span> y=-2
3. When you subsitute y=-2 into the first equation and clear the x, you have:
x=2
</span>
Answer:
equation B is linear. A linear equation will not contain exponents.
Step-by-step explanation:
Assuming the sequence goes on like this 11,-33,99,-297,891,...,
its general formula is
So, the 9th term is
Answer:
A. 219.80 square centimeters
Step-by-step explanation:
The total surface area is given by ...
A = πr(r+s)
where r is the radius and s is the slant height. Filling in the given numbers, you get ...
A = 3.14·(5 cm)·(5 cm +9 cm) = 219.80 cm²
Answer: 629.44
Step-by-step explanation:
562 times .2 = 112.4 that’s the 20% discount. 562-112.4 = 449.6 times 1.4 = 629.44
