Write the equation of the line that is perpendicular to 4x - 3y = 6 and passes through (4, -2)
Svetlanka [38]
Perpendicular is slope multiplies to -1
for
ax+by=c
slope=-a/b

4x-3y=6
-a/b=-4/-3=4/3
perpendicular to 4/3 is -3/4

point slope form
y-y1=m(x-x1)
for slope=m
a point is (x1,y1)

point (4,-2)
slope is -3/4
y-(-2)=-3/4(x-4)
y+2=-3/4(x-4)
or converted
y=-3/4x+1
or
3x+4y=4

Given that tan 0=-4/7 , and 270 degrees &lt;0&lt;360 degrees , what is the exact value of sec0?
Elanso [62]
I take it you meant θ angle, anyway.

we know the tan(θ) = -4/7... alrite, we also know that 270° < θ < 360°, which is another to say that θ is in the IV quadrant, where the adjacent side or "x" value is positive whilst the opposite side or "y" value is negative.

\bf tan(\theta )=\cfrac{\stackrel{opposite}{-4}}{\stackrel{adjacent}{7}}\impliedby \textit{now let's find the \underline{hypotenuse}}&#10;\\\\\\&#10;\textit{using the pythagorean theorem}&#10;\\\\&#10;c^2=a^2+b^2\implies c=\sqrt{a^2+b^2}&#10;\qquad &#10;\begin{cases}&#10;c=hypotenuse\\&#10;a=adjacent\\&#10;b=opposite\\&#10;\end{cases}&#10;\\\\\\&#10;c=\sqrt{7^2+(-4)^2}\implies \implies c=\sqrt{65}\\\\&#10;-------------------------------\\\\&#10;sec(\theta )=\cfrac{\stackrel{hypotenuse}{\sqrt{65}}}{\stackrel{adjacent}{7}}

"Seven eighths of a number is 63." I need to show my work, but I don't know how to do this. PLZ help!
lina2011 [118]

Answer:

seven eights of a number = 7/8 × a number

let the unknown number be = x

\frac{7}{8}  \times x = 63

x = 63  \div ( \frac{7}{8} )

x = 63 \times  \frac{8}{7}

x =  \frac{504}{7}

x = 72
