Answer with Step-by-step explanation:

A line includes points 0 comma negative 5 and 2 comma negative 6.

x + 2y = −10

satisfied at both (0, -5) and (2, -6)

x − 2y = −10

it is not satisfied at (0, -5)

A line includes points 2 comma negative 6 and 4 comma 0

3x − y = 12

satisfied at both (2, -6) and (4,0)

3x + y = 12

it is not satisfied at (2, -6)

Hence, the system contains:

x + 2y = −10

and 3x − y = 12

Hence, Correct option is:

a

x + 2y = −10

3x − y = 12

Find the center and radius for the circles with the following equation x^2+y^2-4x+6y+11=0
Vera_Pavlovna [14]
Rearrange x²+y²-4x+6y=-11 I'll tell you an easy way. take the coefficient of x and divide it by -2 and the coefficient of y and divide it by -2  so -4 ÷-2 = 2           6÷-2= -3 (2,-3) is the center of the circle to know the radius √2² + -3² + -11  =√2  The Radius equals √2

What is the converse of the given conditional statement?
Paha777 [63]
The converse of an if statement is a statement in which the hypothesis and conclusion are switched.

<span>You will get into college if you work hard.

The "if" part is the hypothesis.
The "then" part is the conclusion.

Rewrite the original if statement in the if-then form:

If you work hard, then you will get into college.

The hypothesis is the if part: "you work hard"
The conclusion is the then part: "you will get into college"

To write the converse, switch the hypothesis and the conclusion.

If you get into college, then you worked hard.

This happens to be choice A.

Solve for the angles below. Assume that segments that appear to be tangent are tangent. Round your final answers to the nearest
stepan [7]

Answer:

m∠NSR = 113°

m∠RSP = 67°

Step-by-step explanation:

Angle formed between the intersecting chords is one half the sum of the measures of the arcs intercepted by the angles.

m∠NSR = \frac{1}{2}[\text{arc}(NR)+\text{arc}(PQ)]

             = \frac{1}{2}(176+50)

             = 113°

Since, m∠NSR + m∠RSP = 180° [Linear pair of angles are supplementary]

113° + m∠RSP = 180°

m∠RSP = 180° - 113°

             = 67°
