One solution to a quadratic equation is x= -5/3 What is true about any remaining solutions?

Mathematics

Answer:

There is exactly one more real solution or there is exactly one more complex solution

Step-by-step explanation:

A quadratic equation is a polynomial of degree two

What this means is that a polynomial has two answers.

Now, from the question, we have an answer already which is a real root

Then the other answer which we do not have can take the form of two answers

It can either be a complex root or other wise be a real root

So the answer to this question is that ;

There is exactly one more real solution or there is exactly one more complex solution

Solve each system by substitution
Ira Lisetskai [31]

Answer:

1. 2x + 3y =22

y=4

C. (5,4)

2. y=0

-5x - 2y = -15

B. (3,0)

Step-by-step explanation:

2x+(3)(4)=22

Step 1: Simplify both sides of the equation.

2x+12=22

Step 2: Subtract 12 from both sides.

2x+12−12=22−12

2x=10

Step 3: Divide both sides by 2.

2x/2 = 10/2

x=5

====================================================================

−5x−(2)(0)=−15

Step 1: Simplify both sides of the equation.

−5x−(2)(0)=−15

−5x+0=−15

(−5x)+(0)=−15(Combine Like Terms)

−5x=−15

−5x=−15

Step 2: Divide both sides by -5.

−5x/−5 = −15/−5

x=3

Kamal spent 40% of his income. He
Arte-miy333 [17]

Answer:

<em>(c) Rs. 1500</em>

Step-by-step explanation:

Percentages

It's given Kamal spent 40% of his income. With the remaining 60%, he deposited Rs. 400 in a bank and still has Rs. 500 left.

This means Rs. 400 + Rs. 500= Rs. 900 is 60% if his income.

The 100% of his income is calculated as a percent proportion:

If 60% is Rs. 900, then 100% is:

\displaystyle \frac{900}{60}*100=1500

Thus, Kamal's income is Rs. 1500. Correct choice: (c) Rs. 1500

Nola hiked down a trail at a steady rate for 10 minutes. Her change in elevation was −160 feet. Then she continued to hike down
RoseWind [281]
Ok so first, you need to figure out the change in elevation for each after one min. so we will write it as a ratio

10:-160        20:-300
So for the 10 min one, we will divide both sides by 10
1:-16      So the change in elevation per min. is -16
Now for the 20 one, we will divide by 20.
1: -15   So the change in elevation per  min. is 15

So, the 10 min section of the walk the change of elevation was greater.      Hope that helps! if you need me to explain something just ask!
