Answer:

Below.

Step-by-step explanation:

Total scores = 6*90 = 540.

He had more than one 89 ( mode) and max score - min score = 18.

Let max score = x then min = x-18.

Lets say he has 3 89's then

x +  x - 18 + 3*89 + y  = 540  where y is another score then:

2x + 249 + y = 540

2x + y =  291

x = 98 and y = 95 will fit this so the<em> </em>6 scores could be

80, 89, 89, 89, 95, 98.

Which graph represents the solution to the given system? y = –2x + 5 and y = 3x – 2
DaniilM [7]
Y = -2x + 5        y =3x - 2
Since both equations are equal to 'y' you can set them equal to each other to solve.
-2x + 5 = 3x - 2             Subtract 3x from both sides
-5x + 5 = -2                  Subtract 5 from both sides
-5x = -7                        Divide -5 on both sides
x = 7/5
Plug 7/5 back in for x and solve for y.
y = -2(7/5) + 5
y = (-14/5) + (25/5)
y = 11/5
(7/5, 11/5) OR (1.4, 2.2)

The quadratic function in vertex form of a parabola vertex 1,1 and passes through 4,19
Grace [21]

Answer:

y = 2(x - 1)² + 1

Step-by-step explanation:

The equation of a quadratic function in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (1, 1), thus

y = a(x - 1)² + 1

To find a substitute (4, 19) into the equation

19 = a(4 - 1)² + 1

19 = 9a + 1 ( subtract 1 from both sides )

18 = 9a ( divide both sides by 9 ), thus

a = 2

y = 2(x - 1)² + 1 ← in vertex form

First to answer gets brainliest
skad [1K]

Answer:

Step-by-step explanation:

Because you can't do -x+1 so it would be (1,0) and then you have x^2 +3x-4 which is (-5,6)
