Asystem of equations is given below:
y = –2x + 1
6x + 2y = 22
which of the following steps could be used to solve by substitution?
6x + 2(−2x + 1) = 22
−2x + 1 = 6x + 2y
6(−2x + 1) + 2y = 22
6(y = −2x + 1)

The answer is A

Because this where you gonna start your substitution

The steps that could be used to solve by substitution is:

                    6x + 2(−2x + 1) = 22

Substitution method--

The method of substitution states that from a equation the value of one variable is substituted in form of the other variable into  the other equation.

From the first equation we have the value of y in terms of x as:

               y = -2x + 1

Also, we have equation (2) as:

6x + 2y = 22

Hence, on putting the value of y we have:

                     6x+(-2x+1)=22

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
