Jon has to choose which variable to solve for in order to be able to do the problem below in the most efficient manner. 6 x + 3 y = 27. 5 x + 2 y = 21. Which variable should he choose so that he can use substitution to solve the system?
1 answer:
Answer:
He could choose any of the variable because in order to solve a linear equation one of the two variables should be equal. He can multiply the any of the equation with corresponding numbers and can equal the equation to substitute them.

Answer:
y = 3x^2 + 12x + 8
Step-by-step explanation:
To rewrite in standard from by expanding the equation using the distributive property.
y= 3 (x+2)^2 - 4
y = 3(x^2 + 4x + 4) - 4
y = 3x^2 + 12x + 12 - 4
y = 3x^2 + 12x + 8
Answer:
-4 1/3
Step-by-step explanation:
26 ÷ -6
= 26 / -6 (divide both top and bottom by 2)
= 13 / 3
= -13 / 3
= -4 1/3
Answer:
3/196
Step-by-step explanation:
because if 2 times 14 times 7, you will get 196 and then do 1 times 3 times 1 which equal to 3. so the answer will be 3/196
1. 25 3. 29 5. 14 Hope this helps.
14because2 times 3=6 times 2= 12 plus 2
