Answer:
y = (½)x
Step-by-step explanation:
(-8,-4) (0,0) and (8,4)
Use any 2 points to find the slope, hence the equation
slope = (y2-y1)/(x2-x1)
= (0-(-4))/(0-(-8))
= 4/8
= ½
y = (½)x + c
When x=0, y=0
0 = (½)(0) + c
c = 0
Equation is:
y = (½)x
If the blue part is what is shaded, I'd say it's Graph B. But you can double check on a great website called "https://www.desmos.com/"
B(x) = 100 - 3.5x
84 = 100 - 3.5x
3.5x = 100 - 84 = 16
x = 16/3.5 = 4.6 kilometers
96 = 100 - 3.5x
3.5x = 100 - 96 = 4
x = 4/3.5 = 1.1 kilometers
Therefore, the boiling point of water is between 84°C and 96°C at elevations of between 4.6 kilometers and 1.1 kilometers.
Answer:
n = 5
Step-by-step explanation:
Coordinate of P = (n,3)
R is on y-axis & the y-coordinate of P & R are equal. So coordinate of R = (3,0)
Coordinate of Q = (n,-2)
Using distance formula,
Distance between P & Q =
Distance between P & R =
But in question it is given that distance between P & Q is equal to the distance between P & R. So,
14. You divide the length of ribbon by the size of the pieces wanted so you get
49/3.5 = 14
