Answer:
The correct answer is: Option D) 5
Step-by-step explanation:
Given equation is:
In order to find that which values of x makes the equation true, we have to put each value of x in the equation. When both sides of equations will be equal, that value of x will be true for the equation.
Putting x = 2
Putting x = 3
Putting x=4
Putting x = 5
The equation is true for x = 5
Hence,
The correct answer is: Option D) 5
Answer:
(6-√21, 6+√21)
Step-by-step explanation:
x^2 - 12x = -15
(x - 6)^2 - 36 = -15
(x - 6)^2 = 21
x - 6 = ± √21
x = 6 ± √21
If you would like to know how many hours will Lena need to work before she can afford to buy the computer, you can calculate this using the following steps:
$900 - $473 = $427
$427 / $7 = 61 hours of yard work
Result: Lena will need to work 61 hours before she can afford to buy the computer.
Answer:
13. (E) all of the above 14. (E) the diagonals bisect the angles at the vertices
Step-by-step explanation:
Answer: x = 2/7y + 3/7 and
x= -5/4y + 0.8125
Step-by-step explanation: Let's solve for x.
7x−2y=3
Step 1: Add 2y to both sides.
7x − 2y + 2y= 3 + 2y
7x = 2y + 3
Step 2: Divide both sides by 7.
7x/7 = 2y+3/7 this is for the second answer Step 1: Add -5y to both sides.
4x+5y+−5y=3.25+−5y
4x=−5y+3.25
Step 2: Divide both sides by
4/4 x 4 = −5y + 3.25/4
