Answer:

x=-7/2, x=4/3

Step-by-step explanation:

6x^2+13x-28=0

Multiply 6 and -28 to get -168

Find 2 numbers that multiply to 168 but add to 13

They are 21 & -8

Rewrite the equation into:

6x^2+21x-8x-28=0

Factor

3x(2x+7)-4(2x+7)=0

(3x-4)(2x+7)=0

3x=4

x=4/3

2x=-7

x=-7/2

Find the slope of a line perpendicular to 2x-y-16
Alekssandra [29.7K]

put the equation 2x - y = 16 in the form of y = mx + c

2x - y = 16

2x = 16 + y

y = 2x - 16

the slope of this line is 2. the slope of a line perpendicular to it would be the negative reciprocal of 2. in other words, it would multiply with 2 to give -1.

you can form this equation with that info

2x = -1

x = -1/2

OR

you can flip and change the sign (numerator) of 2/1

2/1

= -1/2
