Solve the system by the elimination method.
2a + 3b = 6
5a + 2b - 4 = 0 

multiply thru the top equation by 2
Multiply thru the bottom equation by 3

4a + 6b = 12
15a+ 6b = 12

Subtract and solve for "a":
11a = 0
a = 0

Solve for "b" using 2a + 3b = 6
2*0 + 3b = 6
b = 2

What are the leading coefficient and degree of the polynomial?
MissTica

Answer:

  • leading coefficient: 2
  • degree: 7

Step-by-step explanation:

The degree of a term with one variable is the exponent of the variable. The degrees of the terms (in the same order) are ...

  6, 0, 7, 1

The highest-degree term is 2x^7. Its coefficient is the "leading" coefficient, because it appears first when the polynomial terms are written in decreasing order of their degree:

  2x^7 -7x^6 -18x -4

The leading coefficient is 2; the degree is 7.

__

<em>Additional comment</em>

When a term has more than one variable, its degree is the sum of the exponents of the variables. The term xy, for example, is degree 2.

Find the y-intercept of the line who's equation is Y = 3.5 x- 0.4.
agasfer [191]
\sf y=mx+b

m is the slope
b is the y-intercept

so that means that the y-intercept of

\sf y=3.5x + .4

is \sf .4

\bf{\huge{\boxed{y-intercept = .4}}}
