Answer:
The range is the output value or the y value.
You would work backwards to find the domain.
f(x) = 4x - 1 f(x) = 4x - 1
3 = 4x - 1 7 = 4x - 1
add 1 to both sides add 1 to both sides
4 = 4x 8 = 4x
divide both sides by 4 divide both sides by 4
x = 1 x = 2
f(x) = 4x - 1 f(x) = 4x - 1
11 = 4x - 1 15 = 4x - 1
add 1 to both sides add 1 to both sides
12 = 4x 16 = 4x
divide both sides by 4 divide both sides by 4
x = 3 x = 4
Domain { 1, 2, 3, 4}
Step-by-step explanation:
Answer: y = -5/6 x - 1
Step-by-step explanation:
The slope is -5/6, which is why x = -5/6. The - 1 is so the line on the graph will pass through (0,-1) and (-6,4).
Answer:
1. x= 12.20
2. x= 8.94
3. x= 31.80
Step-by-step explanation:
1.
H =x , P = 7 and B = 10
using pythagoras theorem
H = 12.20
2.
H =21 , P = x and B = 19
using pythagoras theorem
P = 8.94
3.
H =x , P = 15.09 and B = 28
using pythagoras theorem
P = 31.80
Answer:
w = 7 inches
Step-by-step explanation:
length = n
width = n/2
Perimeter = 2n + 2(n/2)
42 = 2n + n
42 = 3n
n = 14
width = 14/2 = 7
