Answer:
Step-by-step explanation:
The value of AD is found by using the Pyhagorean Theorem:
Besides, BD is measured in terms of the Pythagorean Theorem:
By Algebra:
One way of solving this is simply by substituting for each x in the table into each formula to see if you get the corresponding y in the table
so if x is 1,
then in the first equation -> y = 1-2(1) = y= 1-2 = -1
so right off the bat, we found the right equation
but essentially you should do it until you find the one that fits
Answer:
11 1/3
Step-by-step explanation:
First put in improper form:
17/5 x 10/3 = 34/3 = 11 1/3
Answer:

Step-by-step explanation:
Answer:
The roots are -2 and -3
Step-by-step explanation:
In the function x² + bx + c, <em>a</em> is equal to 1, then the factored form of this function is: (x - x1)*(x - x2) where x1 and x2 are the roots.
Wilma got the following expression:
(x - 1)*(x - 6) = x² - 6x - x + 6 = x² - 7x + 6, where '+6' is correct but '-7x' is incorrect.
Greg got the following expression:
(x + 1)*(x + 4) = x² + 4x + x + 4 = x² + 5x + 4, where '+5x' is correct but '+4' is incorrect.
Therefore the quadratic equation is: x² + 5x + 6. Its roots are:
