Which quadratic function has its vertex at (-2,7) and opens down?

Answers

The \ vertex \ form \ of \ the \ function \ is: \n \ny = a(x - h)^2 + k\n \nvertex = \ is \ the point \n \n(h, k) = (-2,7)\n\nh=-2\nk=7

y=a(x-(-2))^(2) +7\n\ny=a(x+2)^(2) +7 \n\n opens \ up \ down \ for : \ a < 0 \n For \ instance, \ letting \ a = -1 \ gives \ this \ parabola: \n\ny= -(x+2)^(2) +7
The\ vertex\ form:y=a(x-h)^2+k\n\nvertex(h;\ k)\to(-2;\ 7)\n\no pens\ down\ then\ a < 0\n\nAnswer:y=a(x+2)^2+7\ where\ a < 0.

24x + 34p = p
Solve for p

Answers

Answer:

(-24)/(33) x = p

Step-by-step explanation:

24x + 34p = p  Subtract 34 p from both sides of the equation

24x + 34p -34p = p - 34p

24x = -33p  Divide both sides by -33

(24x)/(-33) = (-33p)/(-33)

(24x)/(-33) = p or .2727...

Answers

 -2/5x-9<9/10 One solution was found :                   x > -99/4

Rearrange:

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :

                     -2/5*x-9-(9/10)<0 

Answer:

 x > -99/4

do the points on the line y=4/11x -5 have a slope of the y coordinate to the x coordinate for any point on the line except the y intercept? explain your answer.

Answers

y = (4/11)x - 5 
the slope of this line is 4/11, and the y-intercept is -5
When the line crosses the y axis, that is the y-intercept is when the value of x is zero:
y = (4/11)x - 5 
y = (4/11)(0) - 5 
y = -5
so at this point the equation doesnt have a slope you could say, but only at this point because is when x = 0
