Answer:
8
Step-by-step explanation:
h(t) = -t + 3;
h(-5)
Let t = -5
h(-5) = - -5 +3
= 5+3
= 8
T = 6 [h]
s = 340 [mi]
v=s/t=340/6=56.7 [mi/h]
Answer C.
Answer:
y=9x-17; x=17/9 or x=1 8/9 or x=1.8
y=x+23; x= -23
Step-by-step explanation:
y=9x-17
0=9x-17 (Move variables to the left-hand side and change its sign)
-9x=-17 (Divide both sides of the equation by -9)
x=17/9, x=1 8/9, or x=1.8
y=x+23
0=x+23 (To find x-intercept/zero, substitute y=0)
-x=23 (Move variable to the left-hand side and change its sign)
x= -23 (Change the signs on both sides of the equation)
x= -23
Answer:
8km
Step-by-step explanation:
The three points form a right-angled triangle with 15km as the height and 17km as the hypotenuse.
To find the distance between Lowell and the port which is the base use the pythagorean theorem.
=√17² - 15²
=8km
