We must plugin values:
3(7)-4(0)=21, is CORRECT since 7•3 is 21 and -4•0 is 0
3(11)-4(3)=21 is CORRECT since 3•11=33 and -4•3=-12 so 33-12=21
3(-3)-4(3)=21 is INCORRECT since 3•-3 is -9 and -4•3 is -12, -9-12 is -21
3(-1)-4(-6)=21 is CORRECT since 3•-1 is -3 and -4•-6 is 24 and so 24-3=21
X=6.62
x+1.91=8.53
you have to subtract 1.91 from both sides of the equation to get x alone on one side of the equation. Once you do that you end up with x on one side and 6.62 on the other side, giving you the answer to x.
Answer:
Domain: [1, 7]
Range: [-4, 2]
Step-by-step explanation:
The domain is the set of x-values and the range is the set of y-values.
Answer:
C
Step-by-step explanation:
in the quadratic equation: ax^2+bx+c,
in order to factor when a=1, then we need to find values that add to b and multiply to c.
