Write the equation of a line that passws through the point (1,7) and is perpendicular to y=1/2x-5
Firdavs [7]

Answer:

y=-2x+5

Step-by-step explanation:

For one line to be perpendicular to another, their slopes must multiply to -1. So, we really want the line with slope $-1/(1/2)$ = -2$ that passes through the point (1, 7).

Recall the point-slope form of a line. If you have a point $(x_{1}, y_{1})$ and a slope m, the line through that point with the given slope is $y-y_{1}=m(x-x_{1})$. Plugging in our given point and slope gives our line: y-7=-2(x-1)(point-slope form).

We can convert this line to slope-intercept form, the most common form by expanding the right side and adding 7 to get y by itself:

y-7=-2x+2

y=-2x+5

Hey can you please help me posted picture of question:)
Fudgin [204]
The given trinomial can be factored using factorization as
x²+19x+84
=x²+12x+7x+84
=x(x+12)+7(x+12)
=(x+12)(x+7)

Thus x+12 and x+7 are the factors of the given trinomial. From these we can see x+12 is listed in option A.
So the answer to this question is Option A
