Find the value of x if y=2.5 on the graph of 2x-1=y

Mathematics
1 answer:
Romashka-Z-Leto [24]3 years ago
3 0

Answer:

2x - 1 = y

2x - 1 = 2.5

Use inverse operations

2.5 + 1 = 3.5

3.5 / 2 = 1.75

2 x 1.75 - 1 = 2.5

x = 1.75

Three vertices of a rectangle are given. Find the coordinates of the fourth vertex.
kykrilka [37]
The distance between (2,5) and (6,1) is:

\sf Distance = \sqrt{\left( 6 - 2 \right)^2 + \left( 1 - 5 \right)^2} \\\\  =\sqrt{ 16 + 16} \\  \\ = \boxed{\bf{4 \sqrt{ 2 } }}

The distance between the fourth vertex and (4,-1) should also be 4√2

The only point that gives us that distance is B. (0,3)

\sf Distance = \sqrt{\left( 4 - 0 \right)^2 + \left( -1 - 3 \right)^2} \\ \\= \sqrt{ 16 + 16} \\  \\ = \boxed{\bf{4 \sqrt{ 2 } }}

Your final answer is B. (0,3)

If tap and bre are supplementary and bre is its own complement, find the measure of tap. explain how you arrived at your answer
Pie
Supplementary angles are those whose sum is equal to 180° while those that are complementary are those whose sum is equal to 90°. Since, we are given that bre is the complement of itself, its measure can be calculated through the equation,
                           m∠bre + m∠bre = 90°
                                   m∠bre = 45°

Then, for the relationship of bre and tap, we have the equation,
                       m∠bre + m∠tap = 180°
                        45° + m∠tap = 180°
                                m∠tap = 135°

The measure of tap is equal to 135°.

ankoles [38]
It is multiply by 54 you are multiplying 54 by the hours you've worked to get the amount earned - which means you can find out the missing number for the sixth day. 36 times 54 equals 1,944.
