Step-by-step explanation:
The complete question in the attached figure
we have
we know that
(ab)(x) is equal to the product of a(x) and b(x)
so
Applying distributive property
This is a quadratic equation
The other expressions not produce a quadratic equation
Let's solve your equation step-by-step.
<span><span><span><span><span>7y</span>+5</span>−<span>3y</span></span>+1</span>=<span><span>2y</span>+2
</span></span>Step 1: Simplify both sides of the equation.
<span><span><span><span><span>7y</span>+5</span>−<span>3y</span></span>+1</span>=<span><span>2y</span>+2
</span></span><span>Simplify: (Show steps)
</span><span><span><span>4y</span>+6</span>=<span><span>2y</span>+2
</span></span>Step 2: Subtract 2y from both sides.
<span><span><span><span>4y</span>+6</span>−<span>2y</span></span>=<span><span><span>2y</span>+2</span>−<span>2y
</span></span></span><span><span><span>2y</span>+6</span>=2
</span>Step 3: Subtract 6 from both sides.
<span><span><span><span>2y</span>+6</span>−6</span>=<span>2−6
</span></span><span><span>2y</span>=<span>−4
</span></span>Step 4: Divide both sides by 2.
<span><span><span>2y/</span>2</span>=<span><span>−4/</span>2
</span></span><span>y=<span>−2
</span></span>Answer:
<span>y=<span>−<span>2</span></span></span>
Answer:
8% decrease
Step-by-step explanation:
First work out the difference decrease between the two numbers you are comparing. Then decrease the original number by the new number.Then divide the original number by the decrease and multiply the answer by 100.Next you divide the original number by the new number and multiply by 100. Finally you will get your answer.
So if you want to find the nth term so
1st term=1
2nd term=5
3rd term=25
we notice that 5^1=5 and 5^2=25 , but they are on the second ones so
the expression is
the nth term=5^(n-1)
so 1st term=5^(1-1)=5^0=1
2nd term=5^(2-1)=5^1=5
3rd term=5^(3-1)=5^2=25
and so on
the expression is 5^(n-1)
