A coordinate plane is the exact or close to exact location that an object can be found. So archaeologists can use coordinate planes to find bones.

Hope this helps!

I need help with the questions
riadik2000 [5.3K]

Answer:

Step-by-step explanation:

Hello

please find attached the graph

you can notice that x^2-6x+9 = (x-3)^2

(a) from the graph we can say that there is no maximum and one minimum in x = 3

and then f(3) = 0 so o is the minimum of f

(b) vertex is (3,0)

(c) x = 3 is an axis of symmetry

(d) as x^2-6x+9 = (x-3)^2 the root is 3

(e) y=9 for x = 0 so the y-intercept is 9

do not hesitate if you need further explanation

if you like my answer, tag it as the brainliest :-)

Describe a situation that fits each equation. Describe more than one situation for each equation, if possible.
lisabon 2012 [21]

Answer:

Step-by-step explanation:

4x − 1 = 19

solving for x, x = 5

2x − 4 = 10

x=7

2x + 2y = 48

x=24-7

y=24-x

5x + 2y = 90

x=18-2y/5

y=45-5x/2

all the situations I could find hope this helps for each equation.

sweet t has 2 orange picks for every five green. if there are 21 picks in all, how many picks are orange
jarptica [38.1K]
21 picks
altogether (2x+5x)=21
7x=21
x=3
2*3=6 orange picks

or
x=orange, y = greens
x+y=21
x/y=2/5,---->   y=5x/2
x+5x/2=21
2x/2+5x/2=21
7x/2=21
7x=42,
x=6  orange picks
