$x_{vertex}= \frac{-2}{2 \cdot 3}=- \frac{2}{6}= - \frac{1}{3} \\\\\\ 
y_{vertex}=3 \cdot \left(- \frac{1}{3} \right)^2+2 \cdot \left(- \frac{1}{3} \right)+1=3 \cdot\frac{1}{9} - \frac{2}{3} +1=\frac{1}{3} - \frac{2}{3} +1= \frac{2}{3} \\ \\ \\ \boxed {\text {Answer:} \ \left(- \frac{1}{3}; \frac{2}{3} \right)}$

lutik1710 [3]

Answer:

Step-by-step explanation:

First you have to follow pemdas, which says you have to follow this order:

Parentheses first, exponents second, multiply, divide, add, and then subtract. Always follow from left to right. First solve inside the parentheses.

WILL DO ABSOLUTELY ANYTHING FOR THIS ONE HELP ASAP TIMES

Rina8888 [55]

Given:

The graph of a function $y=h(x)$ .

To find:

The interval where $h(x)>0$ .

Solution:

From the given graph graph it is clear that, the function before x=0 and after x=3.6 lies above the x-axis. So, $h(x)>0$ for $x$ and $x>3.6$ .

The function between x=0 and x=3.6 lies below the x-axis. So, $h(x)$ for $0$ .

Now,

For $-1$ , the graph of h(x) is above the x-axis. So, $h(x)>0$ .

For $0$ , the graph of h(x) is below the x-axis. So, $h(x)$ .

For $1$ , the graph of h(x) is below the x-axis. So, $h(x)$ .

Only for the interval $-1$ , we get $h(x)>0$ .

Therefore, the correct option is A.

Can someone plz help me ty

Ostrovityanka [42]

Answer:

8/15

Step-by-step explanation:

you first want to change your whole number, 4, into a fraction so all you have to do is add a 1 in the denominator so it will be 4/1

then you multiply across

2/15 * 4/1

you first multiply 2 and 4 and your answer will be 8 which is the numerator

then multiply 15 and 1 which is 15, the denominator

then you get

8/15

The smaller triange was dilated to form the larger triangle. What is the value of x?

natka813 [3]

Answer:

x = 14

Step-by-step explanation:

As we can see that the bottom side is equivalent to 3 of the smallest triangle and the side of the larger triangle is equivalent to the 9

This represents that it is dilated by 3 factor

So

= 3 × 3

= 9

Now the other side i.e. 5 of the smallest triangle also need to be dilated by a 3 factor

So the new side is 15

Also the largest triangle is x + 1

So,

15 = x + 1

x = 14
