What is the value of x.​

Mathematics
1 answer:
charle [14.2K]3 years ago
5 0

Answer:

x=13

Step-by-step explanation:

The angle on a straight line is always 180 degrees.

Thus,

(12x-26)+50=180

Remove the brackets:

12x-26+50=180

12x+24=180

Subtract 24 from both sides:

12x+24-24=180-24

12x=156

Divide both sides by 12:

\frac{12x}{12}=\frac{156}{12}\\

x=13

Answer:

Area of shaded region=41 square feet

Area of non shaded region= 87 square feet

Step-by-step explanation:

As, Shaded area is made of different shapes including two rectangles and one triangle

So,

Area of shaded region,

=(8\times2)+(10\times 1)+(\frac{1}{2}\times 3\times10)\\\\ =16+10+15=41 \quad \text{square feet}

Area of non shaded region=total area of rectangular region-Shaded region

=(16\times 8)-(41)\\=128-41\\=87 \quad \text{square feet}

Look at the following graph of the given equation. Determine whether the equation is a function. Explain why or why not.
Vadim26 [7]

The equation y=2x+2 is a function

Explanation:

Given that the graph contains the coordinates (-1,0), (0,2) , (1,4) and (2,6)

We need to determine whether the equation y=2x+2 is a function.

To determine the equation is a function, let us substitute the coordinates in the equation and check whether it satisfies the equation.

Let us substitute the coordinate (-1,0) in the equation y=2x+2

Thus, we have,

0=2(-1)+2

0=-2+2

0=0

Thus, the coordinate (-1,0) satisfies the equation y=2x+2

Substituting the coordinate (0,2) in the equation, we have,

2=2(0)+2

2=2

Thus, the coordinate (0,2) satisfies the equation y=2x+2

Substituting the coordinate (1,4) in the equation y=2x+2

4=2(1)+2

4=4

Thus, the coordinate (1,4) satisfies the equation y=2x+2

Substituting the coordinate (2,6) in the equation, we get,

6=2(2)+2

6=6

Thus, the coordinate (2,6) satisfies the equation y=2x+2

Hence, the coordinates (-1,0), (0,2) , (1,4) and (2,6) satisfies the equation y=2x+2

Thus, the equation y=2x+2 is a function.

HELP! will give brainlest or whatever its called... Triangle ABC has vertices A(–2, 3), B(0, 3), and C(–1, –1). Find the coordin
Tomtit [17]

Answers:

A ' = (-2, -3)

B ' = (0, -3)

C ' = (-1, 1)

=======================================================

Explanation:

To apply an x axis reflection, we simply change the sign of the y coordinate from positive to negative, or vice versa. The x coordinate stays as is.

Algebraically, the reflection rule used can be written as (x,y) \to (x,-y)

Applying this rule to the three given points will mean....

  • Point A = (-2, 3) becomes A ' = (-2, -3)
  • Point B = (0, 3) becomes B ' = (0, -3)
  • Point C = (-1, -1) becomes C ' = (-1, 1)

The diagram is provided below.

Side note: Any points on the x axis will stay where they are. That isn't the case here, but its for any future problem where it may come up. This only applies to x axis reflections.
