Answer:
The result gives the equation: 9x = -7
solution: (-7/9, 4/3)
Step-by-step explanation:
6 x + 2y = − 2
and
3 x − 2y = − 5
add together
6x + 3x + 2y - 2y = -2 + -5
9x + 0 = -7
9x = -7
then x = -7/9
and y = -3x - 1:
y = -3*(-7/9) - 1
y = 7/3 - 1 = 4/3
solution: (-7/9, 4/3)
-----------------------------------------
6x+2y= -2 and 3x−2y =−5
6x + 3x + 2y - 2y = -2 + -5
128 = 128 cause u add them
Answer:
12,145
Step-by-step explanation:
If 347 cans is the max PER week, and they have 35 weeks, then all we need to do is multiply 347 times 35.
347*35 = 12,145
The max amount of cans they can collect in 35 weeks is 12,145 cans.
16. .375 mi
19. 440 yards
20. 500 pounds
21. I don’t fw graphs : 3 hopes this helps sum
9x² - 12x + 4
write the equation with two middle terms that multiply to give 36
9x² - 6x - 6x + 4
by factorisation
3x(3x - 2) - 2(3x - 2)
(3x - 2)²
Thus OPTION A
