Answer:
0; 10; 20
Step-by-step explanation:
x is the independent variable
y is the dependent variable
y is dependent on x
a) For what value of the independent variable will the value of the function be equal to −6
y=0.3x−6
-6 = 0.3x-6
0=0.3x
x = 0
Therefore, if the independent variable is 0, the value of the function will be -6.
b) For what value of the independent variable will the value of the function be equal to −3
y=0.3x−6
-3 = 0.3x-6
0.3x = -3+6
0.3x = 3
x = 3/0.3
x = 10
Therefore, if the independent variable is 10, the value of the function will be -3.
c) For what value of the independent variable will the value of the function be equal to 0.
y=0.3x−6
0=0.3x-6
6 = 0.3x
x = 6/0.3
x = 20
Therefore, if the independent variable is 20, the value of the function will be 0.
Answer:
reflection across the x axis then reflection across the y axis
Step-by-step explanation:
Hot dogs- 4 packs (9 times 4 = 36)
Buns - 3 packs (12 times 3 = 36)
Answer:
88 hrs
Step-by-step explanation:
1/3/4 = 7/4hr ; 7/4 = 1.75hr (the number of hours used to travel for 154km)
154/1.75 = 88 (the number of km van travels per hour)
Answer:
The oldest brother is 20 years old. PLEASE GIVE BRAINLIEST!!!
Step-by-step explanation:
Youngest = 5x - (x+4) = 60 Oldest = 5x - 60
5x - 1(x+4) = 60 5(16) - 60 =
5x - x - 4 = 60 80 - 60 = 20
4x - 4 = 60
4x = 60 + 4
4x = 64
x = 64 ÷ 4 x = 16
Youngest = 16
Middle = 18
Oldest = 20
