Answer:
4 minutes 3 seconds
Step-by-step explanation:
Step one:
Given data
A kangaroo hops 2 kilometers in 3 minutes
The rate/speed is
rate/speed= 2/3 km per minute
Required
the time taken to cover 3 km
Step two:
We know that
rate= distance/time
2/3= 3/t
cross multiply we have
2t=3*3
2t=9
divide both sides by 2
t= 9/2
t= 4.5 minutes
t= 4 minutes 3 seconds
Y: is the number
[Y*(-1)]+(-5)
(-Y)+(-5)
-Y-5

Answer : Interval to Inequality
(a, +∞) x > a "greater than a"
[a, +∞) x ≥ a "greater than or equal to a"
(-∞, a) x < a "less than a"
(-∞, a] x ≤ a "less than or equal to a"
I hope you find this helpful
Answer:
D) y=2/9x2+2x+4
Step-by-step explanation:
y-intercept=4
2 x intercepts= 3 and 6
so y-intercept is point where x is 0 like (0,y)
x-intercept is the opposite y is 0 (x,0)
that means y-intercept is (0,4)
x-intercept is (3,0) and (6,0)
the formula of slope intercept form is
y=mx+b
b= is y-intercept
that means
y=ox^2+mx+4
x-intercept is point where y is 0
so solve
now lets try the first option
This is are quadratic functions
you need to plug in both of these until u get one that is right
change the y until you get both x's
the first option if wrong
second one y = 6x2 + 3x +4 has no x-intercepts
3rd option y=3/4x^2-6x-4
last option is y=
2/
9
x2+2 has points at -6. and -2.9999 or -3
