Answer:

Step-by-step explanation:
To find the x-intercept, substitute 0 for y and solve for x:

Divide both sides by 2:


Add 7 to both sides to isolate x:

The x-intercept for
is 7 at point
.

Remove parentheses:

Subtract 2 from both sides:


The x-intercept for
is -2 at point
.
Finito.

Answer:90minutes
Step-by-step explanation:
Speed=distance/time
Speed=40miles per hour, distance=60miles
40=60/t
Cross multiply
40t=60
Divide both sides by 40
40t/40=60/40
t=1.5 hour =90minutes
35 ?? All I remember is that you have to add the perimeter is the easiest to find
(88sin20)(t - 16t²) = 0
(8(0.3090169944)(t - 16t²) = 0
(2.472135955)(t - 16t²) = 0
2.472135955t - 39.55417528t² = 0
