Answer: y=4x-4

Step-by-step explanation:

To find the equation fo the line parallel to the given line, we can use the given point to find the y-intercept. We know that the slope must stay the same because parallel lines NEVER touch or cross. This means that the slope MUST be the same.

y=4x+b

We can use the given point to find the y-intercept.

8=4(3)+b [multiply]

8=12+b [subtract both sides by 12]

b=-4

Now that we have found the y-intercept, we can complete the equation.

y=4x-4

Which sets include only like terms? Choose all answers that are correct. A. ( -3 abc, -4.9ac, - 2b, - 1/8abc ) B. ( - 1.24 jk ,

kozerog [31]

Well it's only B and D because like terms are where the variables are the same. This only happens at B and D because B has only jk's, and D only has x's

X is an odd number and the sum of the next two consecutive even numbers is less than 90.

Mila [183]

Answer:

Step-by-step explanation:

Let the odd number be x

Therefore,

$(x + 1) + (x + 3) < 90 \\ 2x + 4 < 90 \\ 2x < 86 \\ x < 43$

Therefore, Largest possible odd number of x is 41

Simplify.

<span>(-1/2)(4)(-2)(7y)(-1)

Just start multiplying!

-1/2 * 4 = -2
-2 * -2 = 4
4 * 7y = 28y
28y * -1 = -28y

Since that's not an option I suspect you're missing an x.</span>
