Assoli18 [71]3 years ago
6 0
Lets solve our system of equations step by step:
y=2x-1 equation (1)
3x-y=-1 equation (2)

Step 1. Replace equation (1) in equation (2)
3x-y=-1
3x-(2x-1)=-1
3x-2x+1=-1
x=-2 equation (3)

Step 2. Replace equation (3) in equation (1)
y=2x-1 
y=2(-2)-1
y=-4-1
y=-5

We can conclude that the correct answer is: <span>A (−2, −5) </span>

Write the standard equation of a circle with center (2, −5) and radius 16.
astra-53 [7]

The standard equation of circle when center is (h,k) and radius is 'r'

\left ( x - h \right )^{2} + \left ( y - k \right )^{2} = r^{2}

h = 2 and k = - 5, radius = 16

So equation of the circle is given by

\left ( x - 2 \right )^{2} + \left ( y - (-5) \right )^{2} = 16^{2}

\left ( x - 2 \right )^{2} + \left ( y + 5) \right )^{2} = 256

If a complementary angle measures 24 more than the other what is that angle
Lelu [443]
The definition of a complementary angle is one angle who can be added to another complementary angle to sum to 90 degrees. More simply, just an angle is complementary to another angle if they add up to 90 degrees. In this case, to find the other angle, you subtract 24 from 90 which equals 66 degrees.

Please help me with my question!!
Dmitrij [34]

The question is unclear but I will assume they mean 1/4 and 3 1/2.

Find common denominators.

1/4

3 1/2 -> 3 2/4

Turn into an improper fraction.

3 2/4 -> 14/4

Divide.

14/4 / 1/4

14/4 * 4/1

56/4

14

So, they can make 14 ornaments.

Best of Luck!
