Is x^2+13x-4=0 a quatratic function? Why?

Mathematics

Yes it is a quadratic function. A quadratic function contains the term x^2 and x^2 has the highest exponent in the whole function of a quadratic function. What I mean by this is for example x^3 + x^2 + 2x + 3 is not a quadratic. It includes x^2 but x^3 has the largest exponent. That makes that equation a cubic. Just for more info the largest exponent is referred to as the degree of the function so the degree of a quadratic function is always 2. Hope this helps!

Please help me to solve this problem
Leto [7]
So you can choose any number from 11 to 19.

I'll choose 11 for now.

Then you write, 11, the number, and then spell it out, eleven.

To show how many tens and ones, you can make a place value chart. You would make two boxes, the first one for tens and the other for ones.

You would put a 1 in the tens place and a 1 in the ones place.

I hope this helps!

Nicole has $120. if she saves $20 per week, in how many days will she have $500?
ElenaW [278]
500= 120+20x, where x is weeks

Subtract 120 from both sides
380=20x

Divide both sides by 20
19=x

19 weeks*7 days per week= 133 days

Final answer: 133 days
