Answer:

11

Step-by-step explanation:

it has a vertex at (2,11)

.

f(2) = 11

how to find the vertex;

function equation is f(x) = ax^2 + bx + c

we can find x by :-b/2a, -8/-4 = 2

and by putting the x value we get the y

Answer:

11

Step-by-step explanation:

x= -b/2a

x= -8/2(-2)

x=-4/-2

x=2

f(2) = -2(2) +8(2)+ 3

f(2) = -8 +16 + 3

f(2) = 11

Maximum value is 11

Solve the equation for y. Identify the slope and y- intercept. Then graph the equation. 2y-3x=10
Shkiper50 [21]

Answer:

y=3/2x+5

The slope is 3/2 and the y-intercept is 5

Step-by-step explanation:

Solving for y will give us the slope and y-intercept

Isolate y

2y/2=10+3x/2

y=5+3/2x

The slope is 3/2 and the y-intercept is 5

Graph it by graphing (0,5) and using the slope (up 3 over 2) to put other points
