Determinathe value of y, if x is -4.
Y= 12/x+ 10

y = 7

Step-by-step explanation:

inother to determine the value of y

and  x is given to be =-4

Y= 12/x+ 10

put yhe value of x =-4 anywhere you can sight x in the equation Y= 12/x+ 10

y = 12/-4 + 10

y = -3 + 10

y = 7

In order to check if your answer is correct, put the value of x and y in the question and see if your left hand side is equal to your right hand side

Y= 12/x+ 10

7 = 12/-4 +10

7= -3+10

7=7 proved.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
