The two lines intersect at (-3,4)
-2/3X+2= -2X-2

Add 2X to both sides
Subtract 2 from both sides
Divide both sides by 4/3
You get X=-3
Plug in 3 to one of the equations and you’ll see that y= 4

2x^2 + 3x - 12 when x = 5 help pls

cluponka [151]

$\huge\textsf{Hey there!}$

$\mathsf{2x^2 + 3x - 12}$

$\mathsf{= 2(5)^2 + 3(5) - 12}$

$\mathsf{5^2}$

$\mathsf{= 5 \times 5}$

$\mathsf{\bf = 25}$

$\mathsf{2(25) + 3(5) - 12}$

$\mathsf{2(25)}$

$\mathsf{= \bf 50}$

$\mathsf{3(5)}$

$\mathsf{= \bf 15}$

$\mathsf{= 50 + 15 - 12}$

$\mathsf{50 + 15}$

$\mathsf{= \bf 65}$

65 - 12

$\mathsf{= \bf 53}$

$\boxed{\boxed{\huge\textsf{Answer: \bf 53}}}\huge\checkmark$
