First off, let's keep in mind that perpendicular lines have negative reciprocal slopes, hmmm so what's the slope of y = 2x + 5?
well, notice, that equation is in slope-intercept form, thus
.
so, we're really looking for the equation of a line whose slope is -1/2 and runs through 1,4.
Omg thank you, I really needed some points
Answer:
2^7
Step-by-step explanation:
2^3 x 2^4
= 2^(3+4)
= 2^7
Solve for Y: Y = - 2x + 5
Y = - 2x + 20
I will try to solve your system of equation:
Y = - 2x + 5y; = - 2x + 20
Step: Solve y = - 2x + 5 for y
Step:
Substitute - 2x + 5 for y in y = - 2x + 20
y = - 2x + 20
- 2x + 5 + 2x = - 2x + 20 + 2x (add 2x to both sides)
5 = 20
5 + - 5 = 20 + - 5 ( add - 5 to both sides)
0 = 15
As you can see, we obtain a false equation. This means that the system as No Solutions.
Thus your answer is: No Solution
Hope that helps!!!
