What is y in this equation 6x+5y=-15

marishachu [46]

Answer:

y= -3 -6x/5

Step-by-step explanation:

6x+5y=-15

-6x -6x

-----------------------------------

5y = -15 - 6x

divide both sides by 5

5y/5= -15/5 - 6x/5

y= -3 -6x/5

The graph of y=x^2 -7x+ 12 is a parabola with x-intercepts at

vesna_86 [32]

Answer:

Step-by-step explanation:

$\text{x-intercept is for y = 0}.\\\\\text{We have the function:}\ y=x^2-7x+12.\\\\\text{Put y = 0 and calculate the value(s) of x.}\\\\x^2-7x+12=0\\\\x^2-3x-4x+12=0\\\\x(x-3)-4(x-3)=0\\\\(x-3)(x-4)=0\iff x-3=0\ \vee\ x-4=0\\\\x-3=0\qquad\text{add 3 to both sides}\\\boxed{x=3}\\\\x-4=0\qquad\text{add 4 to both sides}\\\boxed{x=4}$
