Algerba :)) pls help

The first one is B, the second is A

Step-by-step explanation:

For a polynomial to be in standard form, it needs to have the exponents decreasing from left to right. In order from left to right, B goes 7,3,2,1,0, hence it is in standard form.

A polynomial cannot have a fractional exponent, hence a is not a polynomial.

y > 4x + 1

Step-by-step explanation:

Look at the graph. The y-intercept is 1, so we have

y = mx + 1

Now let's find the slope.

Go from the intercept 4 units up and 1 unit to the right. You are at point (1, 5) which is a point on the graph.

slope = m = rise/run = 4/1 = 4

The equation of the dashed line is

y = 4x + 1

The shaded area is "above" the line, so the inequality is

y > 4x + 1
