Answer:
7x - 5 = 11
Step-by-step explanation:
To solve for x, substitute y = -5 into the equation 7x + y = 11.
This becomes 7x + (-5) = 11 or 7x - 5 = 11.

To get the square root of imperfect square we can use the formula , which is usually accurate to about two decimal places,
√X =√S +(X-S)2√S
Where, X = the number you want the square roof of, and S is the closest square you know to x.
For example 75 is an imperfect square
Thus, X=75 and thus the nearest number S = 81, this ,means √81 =9.
Putting this into the formula;
√75= 9+(75-81)/2/2(9)
= 9 + -6/18
= 9-0.33333 = 8.667
= 8.667, thus the square root of 75 is 8.66

im not sure but i think c.
hope this helped !
Step-by-step explanation:
Answer:
The solution to the equation is:
Step-by-step explanation:
Given the equation
Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)
now solving
adding 4 to both sides
simplifying
and also solving
adding 3 to both sides
simplifying
divide both sides by 2
simplifying
Therefore, the solution to the equation is:
