GuDViN [60]3 years ago
8 0

Answer:

D

Step-by-step explanation:

To find the discriminant you do b^2-4(a)(c), which in this case gives you -28. If your discriminant is less than zero, you will have no real roots.

The diameter of a circle has endpoints at (0,11) and (-6,-1). Write the equation of the circle in standard form.
Nata [24]

Answer:

(x - 3)^2 + (y - 6)^2 = 17

Step-by-step explanation:

The standard form of a circle's equation is (x-h)² + (y-k)² = r² where (h,k) is the center and r is the radius.

(x - 3)^2 + (y - 6)^2 = 17

Write the equation of the line in fully simplified slope intercept form <br><br><br> Help please
lys-0071 [83]

9514 1404 393

Answer:

  y = 5/3x -5

Step-by-step explanation:

The slope is the ratio of "rise" to "run" for the line. Here, marked points are 5 units apart vertically and 3 units apart horizontally. The slope is ...

  m = rise/run = +5/3 = 5/3

There is a marked point on the y-axis at y = -5. That is the y-intercept. Then your equation is ...

  y = mx + b . . . . . line with slope m and y-intercept b

  y = 5/3x -5 . . . . . line with slope 5/3 and y-intercept -5

Question 4 of 10
olga55 [171]

Answer:

A

Step-by-step explanation:

The inverse of the statement "if a, then b" will always be "if b, then a". In this case, a = I do my homework and b = it will snow so the inverse is if it snows, then I will do my homework.

In a parallelogram PQRS, if angle P = (2x+25) degrees and angle Q = (3x-5) degrees, then write the measures of angle S and angle
krek1111 [17]

Consecutive angles of a parallelogram are supplementary, so:

2x+25+3x-5=180\\5x+20=180\\5x=160\\x=32

This means m\angle P=2(32)+25=89^{\circ} and that m\angle Q=3(32)-5=91^{\circ}.

Since opposite angles of a parallelogram are congruent,

\boxed{m\angle S=91^{\circ}, m \angle R=89^{\circ}}
