Answer:

x = -1.5.

Step-by-step explanation:

3(7 + 2x) + 3 = 3(5 + x) − 9(x + 1)

21 + 6x + 3 = 15 + 3x - 9x - 9

6x - 3x + 9x = 15 - 9 - 21 - 3

12x = -18

x = -18/12

x = -1.5.

Step-by-step explanation:

3(7 + 2x) + 3 = 3(5+ x) - 9(x + 1)

21 + 6x + 3 = 15 + 3x - 9x - 9

6x + 24 = 6 - 6x

12x = -18

x = -1.5

What is the linear function equation represented by the graph?
Tom [10]

Answer:

Y= -1/2x + 1

Step-by-step explanation:

The equation for a line is Y=Mx+B

M stands for the Slope.

 -Slope is rise/run. So, for this graph the line "rises" 1 point and "runs" left 2 points until meeting the line again. This slope is negative because it "runs" to the left.

B stands for the Y-Intercept

-The Y-intercept is the point at which the line crosses the Y axis. For this example, the line crosses the Y-intercept at (0,1).

Polyhedron P is a cube with a corner removed and relocated to the top of P. Polyhedron Q is a cube. How do their surface areas c
tatiyna

Answer:

  • C. P’s surface area is greater than Q’s surface area.

Step-by-step explanation:

<em>Refer to attached</em>

With a corner removed, it doesn't change surface area of the cube as same area is exposed equal to the area of 3 small faces.

With the corner relocated to the top of the cube, it covers the area of one small face but adds up small 5 faces (4 sides and one top). In total the P has more surface area than the Q.

Correct answer choice is C.

26² = 24² + 7²

676 = 576 + 49

676 = 625 is not a true statement.
