4 0

Answer:

The graph of the function opens downwards.

Step-by-step explanation:

The graph opens upward if the coefficient of x^2 is higher than 0.

But, the coefficient of x^2 (-3) is less than 0.

So the graph of the function opens downwards.

igomit [66]

Answer:

1 1/5 mi

Step-by-step explanation:

We need to add the three legs together

3/10 + 1/2 + 2/5

The common denominator is 10

3/10  =3/10

1/2 *5/5 = 5/10

2/5 *2/2 =4/10

3/10 + 5/10+4/10 = 12/10

10/10 = 10/10+2/10 = 1+2/10  = 1 1/5 mi

uranmaximum [27]

Answer:

x=1

Step-by-step explanation:

To solve this question we will have to open the bracket first

So let's solve the question

5(2x-8)+15=-15

Bracket first

10x-40+15=-15

We will have to solve the question further

10x-25=-15

Add 25 to both sides

10x=10

Let's make x the subject of formula by dividing both sides by 10

x=1

Therefore x is 1
