-3 • (5x + 2y = 7)
-15x - 6y = -21
-2x + 6y = 9
__________
-17x = -12
x = 12/17
5(12/17) + 2y = 7
2y = 7 - 60/17
2y = 3.47
y = 1.735
Since the equation is in slope-intercept form, we know from the definition of slope-intercept form that 6 is the y-intercept.
8a^2 + 3a^2
11a^2
since both have a^2 you only have to add the coefficients
Answer:11
Step-by-step explanation: think about 5+6 then when you add 11 to the -5 you get 6.
