For 4x2 - 5x + 1, the coefficient of the term with an exponent of 2 is .

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
