F = 1.8C + 32 *Replace C with 20
F = 1.8(20) + 32
F = 36 + 32
F = 68
F = 1.8C + 32 *Replace C with 25
F = 1.8(25) + 32
F = 45 + 32
F = 77
Room Temp. in Farenheit ranges from 68 to 77
Answer:
1. 4+2d
2. 3k+20
Step-by-step explanation:
Y = -1/5x + 2
A line perpendicular to another line has an opposite reciprocal slope. What opposite means is that you flip the sign (from - to + or from + to -) and reciprocal means that you flip the numerator and denominator (so if line A is perpendicular to line B and line As slope is -3, line Bs slope would be 1/3).
First find the slope of 5x - y = -3
Add y to both sides
5x = y - 3
Add 3 to both sides
y = 5x + 3
So the slope of the line is 5. That means the slope of of the perpendicular line is -1/5.
Plug the slope of the perpendicular line and the point (5, 1) into point slope form to solve the equation
y - y1 = m(x - x1)
y - 1 = -1/5(x - 5)
y - 1 = -1/5x + 1
y = -1/5x + 2
