A=-.25+6.7t, s=.75+4.5t when Amir catches up a=s so:
-.25+6.7t=.75+4.5t add .25 to both sides
6.7t=1+4.5t subtract 4.5t from both sides
2.2t=1 divide both sides by 2.2
t=10/22 hr
t≈0.45 hr (to nearest hundredth)
Answer:
x=-4
Step-by-step explanation:
X needs to be a number that when 3 is added to it, becomes -1. So, adding 3 to -4 gives you -1, therefore, x=-4. Hope this helped!
Answer:
y =
x - 
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 = -
x - 3 ← is in slope- intercept form
with slope m = - 
Parallel lines have equal slopes , then
y = -
x + c ← is the partial equation of line d
to find c substitute (- 2, - 2 ) into the partial equation
- 2 =
+ c ⇒ c = - 2 -
= - 
y = -
x -
← equation of line d
21,000 + 0.07(21,000) = 21,000 + 1,470 = 22,470
