Answer:
y = - 
x - 3
Step-by-step explanation:
The equation of a line in slope- intercept fprm is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x + 7 is in slope- intercept form
with slope m = 3
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - , thus
y = - x + c ← is the partial equation of the perpendicular line
To find c substitute (3, - 4) into the partial equation
- 4 = - 1 + c ⇒ c = - 4 + 1 = - 3
y = - x - 3 ← equation of perpendicular line
hello!~
i know exactly what your talking about! i just took the test on ed and if you also are or just looking for the answer the answers are..
the second one, the third one, and the fifth one!
have a nice day everyone!!~
3.9 = 4
4.2 = 4
5.5 = 6
6.3 = 6
Hopefully this is what you mean :)
<em>Note: You missed to add the answer choices, so I am solving the overall procedure to determine the radius of the cylinder so that you could easily figure out the right choice.</em>
Answer:
The radius of the cylinder:
Step-by-step explanation:
The volume of a cylinder is represented by the formula
V=πr²h
here
The radius of the cylinder can be computed using the formula of the volume of a cylinder
V = πr²h
r² = V / πh
Taking square roots
Thus, the formula of the radius of the cylinder.
Therefore, the radius of the cylinder:
To find the value of r
We will follow the steps below
Usinf the equation of a slope:
slope(m) =
from the question given;
m= -3/4
x₁ = 3
y₁=4
x₂=-1
y₂=r
substituting the values into the slope formula
we can now simplify and then solve for r
cross-multiply
-3 x -4 = 4(r-4)
12 = 4(r-4)
Divide both-side of the equation by 4
3 = r - 4
add 4 to both-side of the equation
3+4 = r-4+4
7 = r
r=7
Therefore the value of r is 7
