Answer:
y = -2x + 5
Step-by-step explanation:
Given:
Passes through point (1, 3)
Perpendicular to x – 2y = -8
Solve:
x – 2y = -8
y = 1/2x + 4
The slope is m = 1/2
The slope of the perpendicular line is the inverse of the slope of the original equation.
The slope of the inverse equation is m = -2.
Making an inverse equation of y = -2x + a
Find a:
Use point, (1, 3) where (x, y):
3 = (-2)*(1) + a
a = 5
y = -2x + 5
The second choice becouse of the total being changed
Answer:
5 and 4
Step-by-step explanation:
So if, x equals 2 then all you do is turn the x into a 2.
So you rewrite the equation into,
2 + 3 and 2 x 2,
Which would be 5 and 4
Hope this helps!
The correct answer to this question is this one: "D. 11.474"
your calculator probably doesn't do "secant". But sec is 1/cos
so do cos(85) (in degree mode, not radian mode)
then "invert it": 1 / ANS or x^-1 if you have that key
or type
1/cos(85 degrees)= <span>11.4737</span>
