Presumably d meanst distance and t means time.

When t = 1, d = 2.5
When t = 3, d = 4

d = mt + b
2.5 = m + b [t = 1]
4.0 = 3m + b [t = 2]
1.5 = 2m [subtract]
m = .75 = slope
b = 1.75 = d-intercept
d = .75t + 1.75
d = 15/4 + 7/4 [t = 5]
d = 22/4 = 5.5 m from sensor

Which is the result when the equation y = -2/5x + 5/2 is converted to<br> standard form?

mixer [17]

Answer:

$4x+10y-25=0$

Step-by-step explanation:

$y=-\frac{2}{5} x+\frac{5}{2}$

Multiply by 10 on both sides,

$10y=-4x+25\\$

so $4x+10y-25=0$
