Which expression is equivalent to
20x2 - 1) + 3x(1-4)? (Unit 6)

Answer:

x = -1/9y + 4/9

Step-by-step explanation:

9x+y=4

Step 1: Add -y to both sides.

9x+y+−y=4+−y

9x=−y+4

The required equation in slope intercept form is given by y = -9x + 4.

The slope of the line is a tangent angle made by line with horizontal. i.e. m = tanx where x in degrees

In the equation intercept is the value of the linear function where either of the variables is zero.

here,
The slope intercept of the line is given as,
y = mx + c,
Where m = slope of the line and c = y-intercept of the line,

Given equation of line 9x + y = 4
Rearrange the equation,
9x + y = 4
y = -9x + 4

Thus, the required equation in slope intercept form is given by y = -9x + 4.

Answer:

C: $30/hr

Step-by-step explanation:

In order to find the rate per hour you must divide: 150 ÷ 5

Which will give you 30

Also if you took away the 0 in "150" then it would be like says "15 ÷ 5" which is 3 but then you have to add the zero back making it 30

Therefore your overall answer is going to be C, $30/hr
