Answer:
7
Step-by-step explanation:
Answer:
a. has one solution
b. infinite solution
Step-by-step explanation:
a.
2(x - 1) + 6 = 4x - 22
2x - 2 + 6 = 4x - 22
2x - 4x = 2 - 6 - 22
-2x = -26
x = 26/2
x = 13
b.
6(2x + 1) – 2 = 12x + 4
12x + 6 - 2 = 12x + 4
12x - 12x = 4 + 2 - 6
0 = 0
Step-by-step explanation:
1. the table on the left is a function, with the formula : y = x²
2. the table on the right is also a function, indicated by the values of the input are different each others
Answer:
6 times a larger number (so 6y) is equal (=) to the sum of a smaller number and 18 (x+18)
6y = x+18
Twice of larger number (2y) and the difference of smaller number (x) is equal to 6
2y - x = 6
solve for y. Divide both terms for 6.
6y/6 = 1/6x+3
y = 1/6x+3
second equation solve for y
move x to the right of equal
2y = x + 6
y = 1/2x + 3
