which is the best description for the graph below

Answer:

9x + 4.5 − 2x = 2.3 + 7x + 2.2

Step-by-step explanation:

if you simplify then you get 7x+4.5=7x+4.5 which mean 0=0

Answer: I think the answer is 81, but I don’t have a good explanation.

Step-by-step explanation: if you can find the angle next to 12x-3 (D), and the angle of 8+15x they should equal 180 degrees.

The Triangle Exterior Angle Postulate states that the measure of an exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.

In the given problem, the exterior angle is < JDC, and its measure is equal to the sum of the measures of < (12x -3)° and < 32°.

We can set up the following equality statement to solve for the value of x, and find out the measure of < JDC:

m < JDC° =  < (12x -3)° + < 32°

< (8 + 15x)° = < (12x -3)° + < 32°

Subtract 8 from both sides:

8 - 8 + 15x = 12x - 3 + 32 - 8

15x = 12x + 21

Subtract 12x from both sides:

15x - 12x = 12x - 12x + 21

3x = 21

Divide both sides by 3 to solve for x:

3x/3 = 21/3

x = 7

To verify whether the value for x is correct, substitute x = 7 into the equality statement:

m < JDC° =  < (12x -3)° + < 32°

< (8 + 15x)° = < (12x -3)° + < 32°

[8 + 15(7)]° = [12(7) - 3]° + 32°

8° + 105° = 81° + 32°

113° = 113° (True statement). Therefore, the correct value for x = 7.

Therefore, the correct answer is C) m < JDC = 113°.

Hi there!

The ratio of the base to the height is 4:1, so:

12 cm : x cm

12/4 = 3, which is the scale. Thus, x = 3 cm.

Find the area using the equation A = b × h

A = 3 × 12 = 36 cm²

Answer:

I think it's 2,4 and 4,8 maybe I'm not so sure

Answer:

x=(h-12y-2)/4

Step-by-step explanation:

h=4x+12y+2

4x=h-12y-2

x=(h-12y-2)/4

Answer:  Lower left corner (southwest corner)

Domain = {-2, 0, 1, 2, 5}

Range = {-5, -3, -1, 2, 3}

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

Explanation:

The domain is the set of allowed x value inputs. We simply list the x coordinates of each point shown on the graph. Those x coordinates are: -2, 0, 1, 2, 5. Use curly braces to indicate we're dealing with a set.

The range is the set of allowed output y values. We list the y coordinates this time and they are -5, -3, -1, 2, 3. These values are also surrounded by a pair of curly braces.

Answer:

11

Step-by-step explanation:

5 + 7( 6-4) – 2(5 - 1) =

= 5 + 7(2) - 2(4)

= 5 + 14 - 8

= 19 - 8

= 11

Answer:

C. (1, 3) & (6, 3)

Step-by-step explanation:

A is incorrect as the points are only 1 unit apart on the x-axis. (3 - 2 = 1)

B is incorrect as the points are only 2 units apart on the x-axis. (3 - 1 = 2)

C is correct as the points are 5 units apart on the x-axis (6 - 1 = 5)

D is incorrect as the points are 4 units apart on the x-axis (5 - 1 = 4)

Hope this helped! You can also plot the points on graph paper and find the distance that way.

In the given figure, the Angle (6v - 4)° forms vertical opposite angle pair with 50° , so their measures is equal to one another.

that is :

therefore, value of v = 9°

Answer:

[tex]v = 9[/tex]

Step-by-step explanation:

They are vertically opposite angles so (6v-4) = 50°

[tex](6v - 4) = 50 \\ 6v = 50 + 4 \\ 6v = 54 \\ v = \frac{54}{6} \\ v = 9[/tex]

Answer:

the value of s=75°

and the value of t=30°

Answer:

s = 75°

t = 30°

Step-by-step explanation:

Since VW = VX,

s = 75

Since all angles in a triangle add upto 180,

75 + s + t = 180

75 + 75 + t = 180

150 + t = 180

t = 30°

Done

Step-by-step explanation:

let the numbers are:

a, b, and c

the equation would be:

a+b+c = 131

c = 4a

b = a+5

=>

a + a+5 +4a = 131

6a +5 = 131

6a = 131-5

6a = 126

a= 126/6

a = 21

b = a+5 = 21+5

b = 26

c = 4a = 4(21)

c = 84

Answer:

11

Step-by-step explanation:

1. You could solve this as a way of just knowing that 6+11=17.

2. You could also solve this algebraically by subtracting 6 on both sides and getting y=11 because 17-6=11.

Answer:

y=11

Step-by-step explanation:

6+y=17

y=17-6

y=11
