Answer:

The vertex of the graph is (2,5)

Step-by-step explanation:

you need to find what a,b and c are:

a=-2  b=8  c=-3

b/2a=   8/2(-2)

x=2

plug x in to the equation x=2 to find y

y=-2(2)^2+8(2)-3= 5

y=5

Why are the southern slopes of mountains warmer than northern slopes?​
lilavasa [31]
In the northern hemisphere a south-facing slope (more open to sunlight and warm winds) will generally be warmer and drier due to higher levels of evaporation and transpiration than a north-facing slope. So South facing slopes are much warmer.

PLEASE HELP ASAP!!!!! Leo drew a line that is perpendicular to the line shown on the grid and passes through point (F, G). Which
aliya0001 [1]

Answer:

y -G = -1/3 ( x- F)

Step-by-step explanation:

The line on the plane has a slope

m = (y2-y1) /(x2-x1)

(0,-2) and (1,1)

   = (1- -2)/( 1-0)

   = (1+2)/(1-0)

    = 3/1

Perpendicular lines have slopes that multiply to -1

m * 3 = -1

Divide by 3

m = -1/3

The perpendicular line has a slope of -1

The point slope equation is

y - y1 = m(x-x1)

y -G = -1/3 ( x- F)

suter [353]

Answer:

A. y = 3x + 3

Step-by-step explanation:

Slope = change in y / change in x

From 3 to 5 (x) = +2

From 12 to 18 (y) = +6

slope, m = 6/2 = 3

Using point slope form

y - y1 = m (x - x1)

y - 12 = 3 (x - 3)

y - 12 = 3x - 9

y = 3x -9 + 12

y = 3x + 3
