If x varies directly with y and y=12 when x=4,what is the value of y when x=-3

-9

Step-by-step explanation:

If x varies directly with y, we can write an equation like: x = ky, where k is some constant. We want to solve for k first, so let's use the given numbers of y = 12 and x = 4:

x = ky

4 = 12k

k = 1/3

Now, our equation looks like this: x = (1/3)y. We want to find the value of y when x = -3, so plug -3 in for x:

x = (1/3)y

-3 = (1/3)y

y = -9

Thus, the answer is -9.

Hope this helps!

step-by-step explanation:

which of the following statements correctly describes the expression below based on its degree and number of terms?

314 - 7x2 + 11

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
