Answer:
Just substitute "x" with "3".
Step-by-step explanation:
y = 2.4x + 3.1
y = 2.4(3) +3.1
y = 7.2 + 3.1
y= 10.3
Answer: 10.3 minutes
Answer:
350km
Step-by-step explanation:
If a map has a scale of 1: 500000, then 1 cm on the map is 500000 cm
So 7 cm on the map is 35000000 cm = 350 km
3x^2+-8
This answer for (3x+4) (x-2)
Answer:
Distance = 8.06
Step-by-step explanation:
We have to use the distance formula 
.
coordinates of the first point
coordinates of the second point
To solve, plug the appropriate values into the formula.
Answer:
x = -2/3, 0, 3/4
Step-by-step explanation:
The zeros of the polynomial are the solutions or roots or x-intercepts of the function. To find them, use the zero product property to solve for x. Use the property by setting each factor equal to 0.
x = 0 4x-3=0 3x+2 = 0
x = 3/4 x = -2/3
