Area = 11 11/16 = 11.6875
Width 2 3/4 = 2.75

Area = width * height
11.6875 = 2.75 * height
height = 11.6875 / 2.75
          = 4.25

4.25 feet is less than the 5 foot space. Therefore, there is enough space on the wall to hang it.

Nicky wants to surround a 25 in. by 16 in. painting with a frame that is w inches wide. Which quadratic function represents the
iVinArrow [24]

Answer:

Option "D" is the correct answer to the following question.

Step-by-step explanation:

Given:

Length of painting = 25 inch

Height of painting = 16 inch

Width of frame = w inch

Find:

Area of Picture with frame

Computation:

New length of painting = 25 + w + w

New length of painting = 25 + 2w inch

New height of painting = 16 + w + w

New height of painting = 16 + 2w

Area = l x b

So,

Area of Picture with frame = [25 + 2w][16 + 2w]

Area of Picture with frame = 400 + 50w + 32w + 4w²

Area of Picture with frame = 4w² + 82w + 400

Find the output, h, when the input, x, is -18
erastovalidia [21]

Answer:

The output H is 20 when the input, x, is -18

Step-by-step explanation:

H= 17 + x/6

When the input, x, is -18 then the output H will be:

H= 17 + 18/6

H= 17 + 3

H = 20

Answer: The output H is 20 when the input, x, is -18

9x-7=-7 how do you solve this problem
borishaifa [10]
<span>9x-7=-7 
You would add 7 to both sides because you want to get to the point were your variable is alone. 9x = 0 Then you would dicide each side by 9 because after doing this your variable would be alone. x = 0 would be your final answer.

20 POINTS WILL GIVE BRAINLIEST HELP QUICKLY!!
SVETLANKA909090 [29]

Answer:

1.function 1 has a greater rate of change than function 2

3. Function 1 has a greater y-intercept than function 2

Step-by-step explanation:

Using the table we can find the slope using

m = (y2-y1)/ (x2-x1)

m = (29-5)/ (8-0)

     = 24/8

    = 3

The rate of change for the table is 3

The y intercept is (0,5)  


Using the graph  (0,-1)  and (2,0)

m = (y2-y1)/ (x2-x1)

m = (0--1)/ (2-0)

     = (0+1)/2

    = 1/2

The y intercept is (0,-1)


Since 3>1/2 , function 1 has a greater rate of change than function 2

Since 5>-1, function 1 has a greater y-intercept than function 2

The function below is written in vertex form or intercept form. Rewrite them in standard form and show your work.
lora16 [44]

Answer:

The standard form as y=5x^2+30x+41

Step-by-step explanation:

Given: A function which is written in vertex form or intercept form.

We have to re-write it  in standard form that in terms of

Given y = 5(x+3)^2-4

Squaring  using (a+b)^2=a^2+b^2+2ab , we get,  

y=5(x^2+9+6x)-4

Multiply 5 inside , we get,

y=5x^2+45+30x-4

Solving further , we get,

y=5x^2+30x+41

Thus , we have obtained the standard form as y=5x^2+30x+41
