Answer:

10ˣ² +19ˣ + 6

Step-by-step explanation:

5ˣ(2x + 3) + 2 (2x + 3 )

10x² + 15x + 2(2x + 3 )

10x² + 15x + 4x + 6

(5x+2)(2x+3)

5x(2x+3) + 2(2x+3)

10x^2 + 15x +2(2x +3)

10x^2 + 15x + 4x +6

Add like terms

15x + 4x= 19x

10x^2 +19x +6

Choose the equation below that represents the line passing through the point (1, -4) with a slope of 1/2
tatiyna

For this case we have that by definition, the line equation of the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

According to the statement we have:

m = \frac {1} {2}

Thus, the equation is of the form:

y = \frac {1} {2} x + b

We substitute the given point and find "b":

-4 = \frac {1} {2} (1) + b\\-4 = \frac {1} {2} + b\\-4- \frac {1} {2} = b\\b = - \frac {9} {2}

Finally, the equation is of the form:

y = \frac {1} {2} x- \frac {9} {2}

Answer:

y = \frac {1} {2} x- \frac {9} {2}
