-2x + 6y= 18 is in standard form, use y=mx+b to solve that.
Answer: The correct answer is option B: The vertical angle
Step-by-step explanation: Please refer to the picture attached for further details.
The circle with center O has an arc AB with a central angle of 42 degrees as shown in the diagram (not draw to scale).
If the line A is extended to point D and also line B is extended to point C both along the circumference of the circle O, then you would have another arc CD on the circle.
If two intersecting lines AD and BC form a pair of angles (shown here as 42° and x°) the angles are called vertical angles, and vertical angles in a circle are equal.
Hence the only thing that can be shown to measure 42 degrees in the question above is a vertical angle.
5(R + 2) - 6....distribute the 5 thru the parenthesis
5R + 10 - 6 =
5R + 4 <==
inequality : x<1 hope this helps:)!
Answer:
Scale of the new blueprint: 2 inches = 2.5 feet (or 4 inches = 5 feet)
Width of the new blueprint: 14.4 inches
Step-by-step explanation:
To solve this problem we can use rules of three to find each of the questions: blueprint's new scale and new width.
To find the new scale, we can find the real length of the patio first:
2 inches -> 3 feet
14 inches -> X feet
2/14 = 3/X
X = 21 feet
Now we can use this value to create the new scale:
16.8 inches -> 21 feet
2 inches -> X feet
16.8/2 = 21/X
X = 2*21/16.8 = 2.5 feet
So the new scale is 2 inches = 2.5 feet, or 4 inches = 5 feet
Now, to find the new width of the blueprint, we can do the following rule of three:
14 inches of length -> 16.8 inches of length
12 inches of width -> X inches of width
14/12 = 16.8/X
X = 12*16.8/14 = 14.4 inches
