F(x) = -2x^2 - 3x + 5 for x = - 3
f(-3) = -2(-3)^2 -3(-3) + 5
f(-3) = -18 + 9 + 5
f(-3) = -4
Speed=distance/time
Diana: (3/8)/5=3/(5*8)=3/40 mi/s=0.075 mi/s
Fernando: 2 1/2 miles=5/2 miles
(5/2)/(3/4)
multiply outer values and divide by the inner values:
=(5*4)/(2*3)=20/6=10/3 mi/h= 3 1/3 mi/h=3.3...mi/h
Step-by-step explanation:
6x + 21y = 103
-6x + 23y = 51
The signs of the x coefficients are opposite. So adding the equations will eliminate the x terms.
44y = 154
y = 3.5
Answer:
Mike
Step-by-step explanation:
23 x 5 = 215 and Sarah added instead of multiplying
B because the relation does not show a function lmaoo
