The sum of 7 times a number and 6 is 9

Mathematics
1 answer:
lara [203]3 years ago
7 0

Answer:

x≈ -4.71

Step-by-step explanation:

7(x+6)=9

Distribute the 7 into the parenthesis.

7x+ 7(6)= 9

Multiply the numbers.

7x+ 42= 9

Subtract from both sides.

7x+42= 9

    -42  -42

Now, divide to both sides.

<u> 7x</u>= <u>-33</u>

7       7

x= -4.71428571429

x≈ -4.71

Graph y=-1/2x^2-1. Identify the vertex of the graph. tell whether it is a minimum or maximum. (To clarify, 1/2 is a fraction *x^
ahrayia [7]
y= -\frac{1}{2} x^{2}-1 is a quadratic function, so its graph is a parabola.

Notice that the coefficient of x is 0, this always means that the axis of symmetry is the y-axis.

That is, the vertex of the parabola is in the y-axis, so the x-coordinate of the vertex is 0.

for x=0, y=-1. So the vertex is (0, -1)

The coefficient of x^{2} is negative. This means that the parabola opens downwards, so the vertex is a maximum.


Answer: (0, -1) , maximum (none of the choices)

Which statement about the function is true?
krok68 [10]

Answer:

The function is negative for all real values of x where -6< x < -2

Step-by-step explanation:

Given f(x) = (x + 2)(x + 6)

The graph of the function is as shown in the attached figure.

As shown, we can deduce the following:

The function is positive for all real values of x where x > -2 and x < -6

The function is zero at x = -2 and x = -6

The function is negative for all real values of x where -6 < x <-2

Compare the observations to the given statements:

So, The true statement is The function is negative for all real values of x where -6 < x <-2
