Answer:

y >= 8

Step-by-step explanation:

This equation is written in vertex notation, so we know the vertex is (-5,8). The parabola opens upward because the coefficient of the squared term is positive. Therefore, the vertex is the minimum, meaning all y values will be greater than (or equal to) the y-coordinate of the vertex (which is 8). When we convert this into a mathematical inequality, we get y>=8.

Ok this might be wrong but you don’t have much time so I will give my best

I’m pretty sure the of the x and y thing you do this you see the box with the number in it do this the top two says 2 and 4 the left side is x and the right side is y so you see at the bottom of the number Line thing on the right is a little x that where you start so the box of numbers the fist one says 2 so go to the bottom number line and there is the number two now the top right box with numbers says 4 so go up 4 squares from the number 2 and make a dot where they come together

Select the correct answer. Which point lies on the circle represented by the equation (x + 7)2 + (y − 10)2 = 132? A. (5,12) B. (

Feliz [49]

Answer:

B. (-7,-3)

Step-by-step explanation:

Given the circle: $(x + 7)^2 + (y - 10)^2 = 13^2$

The point (x,y) which lie on the circle are the coordinate which satisfies the given equation of the circle.

We now consider the given options.

Option A (5,12)

When x=5, y=12

$(5 + 7)^2 + (12 - 10)^2 =12^2+2^2=148\neq 169= 13^2$

Option B (-7,-3)

When x=-7, y=-3

$(-7 + 7)^2 + (-3 - 10)^2 =0^2+(-13)^2= 169=13^2$

Option C (-6,-10)

When x=-6, y=-10

$(-6 + 7)^2 + (-10 - 10)^2 =1^2+(-20)^2=401\neq 169= 13^2$

Option D (6,23)

When x=6, y=23

$(6 + 7)^2 + (23 - 10)^2 =13^2+13^2=338\neq 169= 13^2$

We can see that only (-7,-3) satisfies the equation of the circle. Thus it is the point which lies on the circle.

The correct option is B.

Solve the equation for x, where x is a real number (5 points): -2x^2 + 7x + 7 = 6

Artemon [7]

Start by doing a subtraction of 6 to both sides so that the equation becomes -2x^2 + 7x + 1 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
                             x = [ -b ± √(b^2 - 4ac) ] / (2a)
                             x = [ -7 ± √((7)^2 - 4(-2)(1)) ] / ( 2(-2) )
                             x = [-7 ± √(49 - (-8) ) ] / ( -4 )
                             x = [-7 ± √(57) ] / ( -4)
                             x = [-7 ± sqrt(57) ] / ( -4 )
                             x = 7/4 ± -sqrt(57)/4
The answers are 7/4 + sqrt(57)/4 and 7/4 - sqrt(57)/4.
