1 = 1/2(0) + 1

2 = 1/2(2) + 1

3 = 1/2(4) + 1

4 = 1/2(6) + 1

hope this helps!

7/2 inches by 3/2 inches?

miskamm [114]

Answer:

5.25 inches or $5 \frac{1}{4}$ inches

Step-by-step explanation:

I believe that the question is what do they multiply to..? If so, we start by making them both in decimal form:

7 / 2 = 3.5

3 / 2 = 1.5

Now, we multiply:

3.5 * 1.5 = 5.25

If you want fraction form, we can turn .25 to 1/4.

Fraction form: $5 \frac{1}{4}$

Find the y-intercept of the quadratic function f(x) = (2x - 5)2

Vera_Pavlovna [14]

Answer: -10

Step-by-step explanation:

f(x) = (2x - 5)2

f(x) = 4x - 10

To find y-intercept put x = 0, this is because x is 0 at y-axis line.

f(0) = 4*0 - 10

f(0) = -10

Which statements about the function are true? Select two

iogann1982 [59]

Answer:

The vertex of the function is at (1,-25)

Step-by-step explanation:

I think your question missed key information, allow me to add in and hope it will fit the orginal one.

Part of the graph of the function f(x) = (x + 4)(x-6) is shown below.

Which statements about the function are true? Select two

options.

The vertex of the function is at (1,-25).

The vertex of the function is at (1,-24).

The graph is increasing only on the interval -4< x < 6.

The graph is positive only on one interval, where x <-4.

The graph is negative on the entire interval

My answer:

Given the factored form of the function:

f(x) = (x + 4)(x-6)

<=> f(x) = $x^{2} - 2x -24$

We will convert to vertex form

<=> f(x) = ( $x^{2} - 2x +1$ ) - 25

<=> f(x) = $(x-1)^{2} -25$

=> the vertex of the function is: (1,-25)

We choose: a. The vertex of the function is at (1,-25)

Let analyse other possible answers:

c. The graph is increasing only on the interval -4< x < 6.

Because the parameter a =1 so the graph open up all over its domain and the vertex is the lowest point.

So the graph is increasing in the domain (1, +∞)

=> C is wrong

d. The graph is positive only on one interval, where x <-4

Wrong, The graph is positive only on one interval, where x > 6

e. The graph is negative on the entire interval

Wrong, The graph is negative only on one interval, where -4< x < 6.

Barbara was asked by her teacher to subtract 2 from a number and to divide the result

damaskus [11]

Answer:

Step-by-step explanation:

To find the right answer, do her work in reverse

37 times 2 = 74

74 + 6 = 80

Barbara had started with the number 80

Now do the work the way the teacher asked her to do it

80 - 2 = 78

78 / 6 = 13

Hope this helps!
