Answer:

She can buy no more than 22 decorations

Step-by-step explanation:

The costs for the party are food and decorations

Cost = food + decorations * costs per decoration

We can spend no more than 300

Food is 75

Decorations are 10 each

Let d= the number of decorations

300 >= 75 + 10 * d

Subtract 75 from each side

300-75 >= 75-75 + 10 * d

225 >= 10d

Divide each side by 10

225/10 >=10d/10

22.5 >=d

She can buy no more than 22 decorations

Which is the graph of y = 5log(x+3)

Maurinko [17]

Answer:

We are given a equation as:

5log(x+3)=5

We are asked to find a graph that is used to solve the above equation.

We can write the given equation as:

we will divide both side of the equation by 5 to obtain:

log(x+3)=1

Now we have to determine which graph represents the function:

y=log(x+3)

since we know that when x=-2.

y=log(-2+3)=log(1)=0

Hence, the graph should pass through (-2,0).

Hence, the graph that satisfies this is attached to the answer.

F(x)=x²+4x-7 determine the vertex

asambeis [7]

Answer:

The vertex of this parabola is $(-2,-11)$

Step-by-step explanation:

One way of finding the x-coordinate of the vertex of a parabola is by using the equation $-\frac{b}{2a}$

From the function $f(x)=x^2+4x-7$ , we can see that

$a=1\\b=4\\c=-7$

This means that

$-\frac{b}{2a}=-\frac{4}{2(1)} =-2$

So, the x-value of the vertex is -2. Now, we can plug this x-value into the function to find the y-coordinate of the point.

$f(x)=x^2+4x-7\\\\f(-2)=(-2)^2+4(-2)-7\\\\f(-2)= 4-8-7\\\\f(-2)=-11$

Thus, the vertex of this parabola is $(-2,-11)$
