Answer:
An equation like 2x + 3 = 7 is a simple type called a linear equation in one ... There are other types of equations, however, that can have several solutions. ... to solve an equation algebraically and you end up with an obvious identity (like 3 = 3)
Step-by-step explanation:
First you input the equation into the quadratic formula:
__________
x=<span><span><span>−<span>(<span>−2</span>)</span></span>±<span>√<span><span><span>(<span>−2</span>)</span>2</span>−<span><span>4<span>(1)</span></span><span>(5)</span></span></span></span></span>
</span> -----------------------------

Next you simplify the formula:
___
x=<span><span>2±<span>√<span>−16
</span></span></span></span> ------------

This problem has no real solutions.
A=xy
If there is 10% increase in x then,
New value of x = x + 10%of x =1.1x
similarly for y
New value of y after increase= 1.1 y
New value of A after increase in x and y = 1 .1x × 1.1 y= 1.21xy
now
increase amount in A= New value of A - old value of A
=1.21xy - xy= 0.21xy
percentage increase in A= (0.21xy÷xy )× 100= 21%
Answer:
2/3
Step-by-step explanation:
7/12+1/12=8/12
<u>8</u> / 4 <u>2</u>
12 / 4 3
Final answer 2/3
