Answer:
The one on the top right
Step-by-step explanation:
first, look at the y-intercept:
two of the graphs (top-right and bottom-left) have the correct y-intercept of (0, -1).
(The y-intercept is 0 and then the last term of the equation in this form)
next, look at the slope:
slope is in the form of rise/run
the slope for this equation is 3, or 3/1
so look at the graphs, find the y-intercept point and go up three cells and over one.
Only one of the graph's lines goes through this point, and that is the top-left one

Jillian and Dawn are playing a game of miniature golf. In this game, the score on a hole is the number of putts it takes to get the ball into the hole. The winner is the player with the lowest score. After playing 18 holes, Jillian’s mean is 2.4 and Dawn’s mean is 3.3. Which explains who won the game?
Jillian won the game because her score varied less than Dawn’s score.
Jillian won the game because the person with the lower mean took fewer putts on average for each hole.
Dawn won the game because the person with the greater mean played better.
Dawn won the game because her mean absolute deviation was less than Jillian’s.

if a = 5+2√6 then find a²-1÷a²
Answer:
a²+1/a² = 7
Step-by-step explanation:
Given, a = (3+√5)/2
We have to find the value of a² + 1/a².
1/a = 1/((3+√5)/2) = 2/(3+√5)
By taking conjugate,
2/(3+√5) = 2/(3+√5) × (3-√5)/(3-√5)
= 2(3-√5) / (3+√5)(3-√5)
By using algebraic identity,
(a - b)(a + b) = a² - b²
(3+√5)(3-√5) = (3)² - (√5)²
= 9 - 5
= 4
2(3-√5) / (3+√5)(3-√5) = 2(3-√5) / 4
So, 1/a = (3-√5)/2
Now, a² = [(3+√5)/2]²
= (3+√5)²/4
By using algebraic identity,
(a + b)² = a² + 2ab + b²
(3+√5)² = (3)² + 2(3)(√5) + (√5)²
= 9 + 6√5 + 5
= 14 + 6√5
a² = (14+6√5)/4
= 2(7+3√5)/4
a² = (7+3√5)/2
Now, 1/a² = [(3-√5)/2]²
= (3-√5)²/4
By using algebraic identity,
(a - b)² = a² - 2ab + b²
(3-√5)² = (3)² - 2(3)(√5) + (√5)²
= 9 - 6√5 + 5
= 14 - 6√5
1/a² = (14-6√5)/4
1/a² = (7-3√5)/2
a²+1/a² = (7+3√5)/2 + (7-3√5)/2
= 7/2 + 3√5/2 + 7/2 - 3√5/2
= 7/2 + 7/2
= 7
Therefore, a²+1/a² = 7
What is the Area of the circle in pi units if the diameter is 6 cm?
Answer:
9π cm
Step-by-step explanation:
Given diameter of circle (d) = 6cm
radius (r) = d/2 = 6/2 = 3cm
Area of circle = πr²
= π × 3²
= π × 9
= 9π
The area of the circle in pi units when the diameter of this circle is 6 centimeters is 9π centimeters.
What is the area of the circle?
The area of the circle is the space occupied by it. It is the product of pi and square of its diameter divided by 4. The area of the circle can be given as,
[tex]A=\pi\dfrac{d^2}{4}[/tex]
Here (d) is the diameter of the circle. The diameter of the circle is 6 cm.
[tex]d=6[/tex]
Put this value in the above formula to find the area of the circle as,
[tex]A=\pi\dfrac{6^2}{4}\\A=\pi\dfrac{36}{4}\\A=\pi\times9\\A=9\pi\rm\; cm[/tex]
Thus, the area of the circle in pi units when the diameter of this circle is 6 centimeters is 9π centimeters.

line pass through the line (-3, -7.5)tahila determined that the equation of line n is y=0.5x explain the error tahila made while dterming her equation and include the correct equation in your answer
The equation of the line will be (assuming the y-intercept equal to zero):
y = 2.5*x
What is Tahila's mistake?
We know that we have a linear equation of the form:
y = a*x + b
Such that we know that the line passes through (-3, -7.5), notice that the proposed equation is:
y = 0.5*x
If you evaluate that in -3, you get:
y = 0.5*-3 = -1.5
So this line does not pass through (-3, -7.5).
If we assume that b = 0 in the linear equation, then we can find the value of a as:
-7.5 = a*-3
a = 7.5/3 = 2.5
Then the linear equation is:
y = 2.5*x

how would I solve y=9(x+3)(x-1) I need to find the vertex and the X intercepts
Answer:
See below ~
Step-by-step explanation:
Finding the x-intercepts :
The x-intercept's y-value is always 00 = 9(x + 3)(x - 1)x + 3 = 0 ⇒ x = -3x - 1 = 0 ⇒ x = 1So, hence the x-intercepts are : (-3, 0) and (1, 0)Finding the vertex :
Expand the polynomial from factorized formy = 9(x + 3)(x - 1)y = 9(x² + 3x - x - 3)y = 9(x² + 2x - 3)y = 9x² + 18x - 27Vertex = (h, k)h = -b/2a = -18/2(9) = -1k = 9(-1 + 3)(-1 - 1)k = 9(2)(-2)k = 9(-4) = -36Vertex = (-1, -36)Answer:
x-intercepts: x = 1 and x = -3
vertex: (-1, -36)
Step-by-step explanation:
x-interceptsx-intercepts are when y = 0
⇒ 9(x + 3)(x - 1) = 0
Divide both sides by 9:
⇒ (x + 3)(x - 1) = 0
Therefore:
⇒ (x + 3) = 0 ⇒ x = -3
⇒ (x - 1) = 0 ⇒ x = 1
Therefore the x-intercepts are x = 1 and x = -3
VertexVertex form: [tex]y=a(x-h)^2+k[/tex] where (h, k) is the vertex
Completing the square
[tex]\begin{aligned}y & =ax^2+bx+c\\& =a\left(x^2+\dfrac{b}{a}x\right)+c\\\\& =a\left(x^2+\dfrac{b}{a}x+\left(\dfrac{b}{2a}\right)^2\right)+c-a\left(\dfrac{b}{2a}\right)^2\\\\& =a\left(x-\left(-\dfrac{b}{2a}\right)\right)^2+c-\dfrac{b^2}{4a}\end{aligned}[/tex]
Therefore:
[tex]y=9(x+3)(x-1)[/tex]
[tex]\implies y=9x^2+18x-27[/tex]
Completing the square to rewrite the equation in vertex form:
[tex]\begin{aligned}y & =9x^2+18x-27\\& =9\left(x^2+\dfrac{18}{9}x\right)-27\\\\& =a\left(x^2+\dfrac{18}{9}x+\left(\dfrac{18}{2(9)}\right)^2\right)-27-9\left(\dfrac{18}{2(9)}\right)^2\\\\& =9\left(x-\left(-\dfrac{18}{2(9)}\right)\right)^2-27-\dfrac{18^2}{4(9)}\\\\& =9(x+1)^2-36\end{aligned}[/tex]
Therefore, the vertex is (-1, -36)
