A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

If 2a-3b11 and ab7 find the value of a and b?

I take it you mean if 2a - 3b = 11 an a+b = 7 then find the value of a and b. The problem with this site is that the questions can't contain things like the equal sign To solve a problem like this we need to get two of the letter values to be the same, and then we can subtract one equation from the other. so, if we multiply the second equation by -2 we get -2a - 2b = -14 No to that we add 2a - 3b = 11 and we get -5b = -3 so b = 3/5 Now we can replace the b in the second equation and we get a + 3/5 = 7 So we can see that a must equal 62/5 and if we put these values into the first equation the two sides of the equation should balance... 2 (62/5) - 3(3/5) should equal 11... so we'll multiply the values and check 2 (62/5) = 124/5 and 3(3/5) = 9/5 = 14/5 and indeed 124/5 - 14/5 does indeed = 11.

What is the equation 2a-b3?

Firstly, I think you mean 2a-3b. The numbers always come first. Secondly, 2a-3b is an expression, not an equation as equations have equeal signs in them. Lastly, you do not have enough information to solve 2a-3b since it is an expression. Therefore, the answer to your question is 2a-3b.

What is 2a equals b?

2a = b Is an example of an equation with linear dependence between the variable a and b (b is twice a)If you know any a you can find the bIf you graph this equation with a on one axis and b on the other (perpendicular) you will get a straight line

Why is the equation of the line of symmetry x equals negative b over 2a?

The question refers to the equation of a parabola, that is, a quadratic equation of the form y = ax2 + bx + c. Suppose x1 = -b/2a - z and x2 = -b/2a + z for some real number z. Then y1 = a*(-b/2a - z)2 + b*(-b/2a - z) + c = b2/4a + bz + az2 - b2/2a - bz + c = b2/4a + az2 - b2/2a + c and y2 = (-b/2a + z)2 + b*(-b/2a + z) + c = b2/4a - bz + az2 - b2/2a + bz + c = b2/4a + az2 - b2/2a + c So y1 = y2 thus, if x is the same distance (z) either side of -b/2a, then the corresponding y values are the same. And that, is what a line of symmetry means.
