Step-by-step explanation:
conditional :
3-2x ≥ 0
-2x ≥-3
x ≤ 3/2
1-x ≥ 0
-x≥ -1
x ≤ 1
so, the domain is:
{ x | x € the Real numbers, x ≤ 1}
Step-by-step explanation:
step 1. let's call the line in the middle y.
step 2. y = sqrt(5^2 + 7^2) = sqrt(74). pythagorean theorem.
step 3. x^2 + y^2 =100 (pythagorean theorem))
step 4. x^2 + (sqrt(74))^2 = 100.
step 5. x^2 = 100 - 74
step 6. x^2 = 26
step 7. x = sqrt(26). note: sqrt is the square root.
Answer:
account
Step-by-step explanation:
Answer:
(7x+4) and (4x)
Step-by-step explanation:
The expression are (7x+4) and (4x)
30.63 for 3 sets of pencils......that means each set cost (30.63 / 3) =
10.21....so the change in his account for 1 set of pencils is -$ 10.21 <=
