which of the following is the missing reason? Statements Reasons three halves times x plus 5 equals negative 4 Given 3x + 10 = −
den301095 [7]

Answer:

The missing reason is Subtraction Property of Equality.

Step-by-step explanation:

\frac{3}{2}x+5=-4    ⇒ (Given)

On Solving we get;

Multiplying 2 on both side we get;

2(\frac{3}{2}x+5)=-4\times2\\\\2\times \frac{3}{2}x+5\times 2=-4\times 2

3x+10=-8   ⇒ (Multiplication Property of Equality)

Now Subtracting Both side by 10 we get;

3x+10-10=-8-10

3x = -18     ⇒ (Subtraction Property of Equality)

Now Dividing both side by 3 we get;

\frac{3x}{3} = \frac{-18}{3}

x=-6        ⇒ (Division Property of Equality)

Hence the missing reason is Subtraction Property of Equality.

Triangle ABC has vertices at A(1,2) B(4,6) and C(4,6) in the coordinate plane. The triangle will be reflected over the x-axis an
k0ka [10]
You should know that you can predict changes in coordinates after translations without a graph or anything like that.

(x, y) reflected over the x axis = (x, -y)
(x, y) reflected over the y axis = (-x, y)
(x, y) rotated 90 degrees around the origin = (y, -x)
(x, y) rotated 180 degrees around the origin = (-x, -y)
(x, y) rotated 270 degrees around the origin - (-x, y)

So here's our set of points.
A(1, 2), B(4, 6), C(4, 6)

Here's those points reflected over the x axis.
A'(1, -2), B'(4, -6), C'(4, -6)

And here's <em>those</em> points rotated 180° around the origin.
A''(2, -1), B''(6, -4), C''(6, -4)

I think you made a mistake writing down the question, though, because B and C are the same yet you say ABC forms a triangle. You should be able to go through this process with whatever the coordinate was supposed to be.
