(B) y=−2x+2
(C) y=2x+3
(D) y=2x+5
Answer:
y = - x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x + 2 ← is in slope- intercept form
with slope m = 2
Given a line with slope m then the slope of a line perpendicular to it is
= - = - , thus
y = - x + c ← is the partial equation
To find c substitute (4, 3) into the partial equation
3 = - 2 + c ⇒ c = 3 + 2 = 5
y = - x + 5 ← equation of perpendicular line
Answer:
x = 2
Step-by-step explanation:
Step 1: Convert to math
5x + 1 = 3x + 5
Step 2: Solve for x
Step 3: Check
Plug in x to verify it's a solution.
5(2) + 1 = 3(2) + 5
10 + 1 = 6 + 5
11 = 11
Answer:
2
Step-by-step explanation:
there are 5 x's and 1 positive one of the left side, and 3 x's and five positive one's on the right side. when you put this into an equation, you get:
5x+1 = 3x+5
the first step to solving the equation is to subtract 3x from both sides:
5x+1 -3x = 3x+5 -3x
2x+1 = 5
next, subtract 1 from both sides:
2x+1 -1 = 5 -1
2x=4
finally, divide both sides by 2:
2x ÷2 = 4 ÷2
x=2
and the answer is: 2
Answer:
Step-by-step explanation:
line RPN = 180 = 4y - 10 + 90 + y
180 - 90 + 10= 5y
100 = 5y
y = 100/5
y = 20
Answer:
Step-by-step explanation:
Perimeter is the sum of the side lengths
If polygon A has perimeter
Then polygon B has perimeter of
Since P = 144
We can write a ratio comparing the sides of both polygons.
A:B = 3:1
Since we know that 144 is the perimeter for polygon A, we can substitute it.
144:B = 3:1
~Simplify
144 = 3B
Divide 3 to both sides
48 = B
Therefore, the perimeter of B is 48 units.
Best of Luck!
I believe it's 2a + 2c So sory if it's wrong!
