Answer:
The equation of the line would be y = -2x + 10
Step-by-step explanation:
In order to find the equation of this line, we first have to note that perpendicular lines have opposite and reciprocal slopes. Therefore, since the original line has a slope of 1/2, we know the new line will have a slope of -2. Now we can use that information along with the given point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 8 = -2(x - 1)
y - 8 = -2x + 2
y = -2x + 10
Answer:
n = -1
Explanation:
First we need to distribute the -2 throughout the variable getting us to
-12 - 14n = 3n + 5
Then we need to move the variable n to one side and isolate it. To do this, subtract 3n from both sides and add 12 to both sides.
-17n = 17
Now, we need to remove the co-efficient from n, so we need to divide both side by -17.
n = -1
Answer:
x = 4
Step-by-step explanation:
Given
4x + 3 = 19 ( subtract 3 from both sides )
4x = 16 ( divide both sides by 4 )
x = 4
N represents the unknown number
4(3+n)=32
use the distributive property for 4(3+n)
12+4n=32
subtract 12 from both sides
4n=20
divide both sides by 4
n=5
The number is 5.
Answer:
Step-by-step explanation:
Just try putting those into an equation!
The value of<em> x </em>= <em>1/3 </em>of the value of <em>45-10x</em>
<em>=> x= </em>
(45-10x)
=> x= 15 - 3 1/3x
=> 4 1/3x = 15
=> solve it! U should know how now. :)
