Write the equation of the function.
Hoochie [10]

Answer:

f(x)=2sqrt( x + 3)

Step-by-step explanation:

We know it's a square root function because of the shape of the graph and it's moved to the left by 3 unit, so it has a d value of +3. We know it doesn't have a c value because it doesn't have a vertical translation as it's still at 0. For the a value, you can figure it out my substituting the graph points in and the values you know now then isolating and solving for the a value.

-5x^2=-500 what is the answer
omeli [17]

Answer:

x = ± 10

Step-by-step explanation:

- 5x² = - 500 ( divide both sides by - 5 )

x² = 100 ( take square root of both sides )

x = ± \sqrt{100} = ± 10

That is x = - 10 or x = 10

Please guys this is easy, I need help ASAP! (Giving brainliest)!
jasenka [17]

Answer:

4a. 13

4b. -4

Step-by-step explanation:

2x-6/5 = 4 (Muti each side by 5)

2x-6 = 20

2x = 26 (Divide each side by 2)

x = 13

7- 2x/4 = 9

-2x/4 = 2 (Muti each side by 4)

-2x = 8 (Divide each side by -2)

x = -4

Find ​(a) PQ to the nearest tenth and ​(b) the coordinates of the midpoint of __ pq.
lutik1710 [3]

Answer:

a) 5units

b) (4.5, 4)

Step-by-step explanation:

Let the coordinate of P and Q be P(3, 2) and Q(6, 6)

PQ can be gotten using the distance formula;

PQ =√(6-2)²+(6-3)²

PQ = √4²+3²

PQ =√16+9

PQ =√25

PQ = 5units

Midpoint M is  expressed as;

M(X, Y) = {(x1+x2)/2, y1+y2/2}

X = x1+x2/2

X = 3+6/2

X= 9/2

X = 4.5

Similarly;

Y = y1+y2/2

Y = 2+6/2

Y = 8/2

Y = 4

Hence the midpoint of PQ is (4.5, 4)
