I believe it’s A. Because each x only can have one y. Every other equation has two different y if the same x. (Sorry if it doesn’t make sense)

A is the only function.



If they list out the x’s (like in B and C) and they have two of the same x’s, it is not a function. If they have those circles (like in D) and one x goes to multiple y’s, then it is also not a function. Hope this helps!

Write the equation of the line<br> perpendicular to y = *x+7 with a<br> y-intercept of (0-1)
I am Lyosha [343]

Answer:  y = -x - 1

<u>Step-by-step explanation:</u>

Use the Point-Slope formula: y - y_1=m_{\perp}(x-x_1)   where

  • (x₁ , y₁) is the given point (0, -1)
  • m_{\perp}\ \text{is the opposite reciprocal slope of the given line}\implies m_{\perp}=-1

Insert those values into the formula and solve for y:

y - (-1) = -1(x - 0)

y + 1 = -x

y      = -x - 1

Which expressions are equivalent to the one below? Check all that apply.
dem82 [27]

Answer:

Recall from Logarithm law Log a - Log b = Log (a/b)

so, Log 2 - Log 4 = Log ( 2/4)

                            = Log ( 1/2).

Also from the law

Log (a/b) = Log a - Log b

i.e Log (1/2) = Log 1 - Log 2

Recall: Log 1 = 0

which implies : Log 1 - Log 2 = 0 - Log 2

                                               = - Log 2

Step-by-step explanation:
