Find the value of c that completes the square

x^2-16x+c

Please help me with how to do this, and show me. Thank you.

Answers

Answer 1

Answer:

c = 64

Step-by-step explanation:

Given

x² - 16x + c

To complete the square

add ( half the coefficient of the x- term )² to x² - 16x

x² + 2(- 8)x + 64

= (x - 8)²

Thus

x² - 16x + 64 = (x - 8)² ← a perfect square

with c = 64

what is the 9th term of the linear sequence below 2 5 8 11 14​

Answers

answer is 26!
the difference from each increment is +3 and since you’re trying to find the 9th term there will be 8 ‘gaps’ so u multiply 8 by 3 to find the total increase before adding it to 2, which is the initial no.

2 + (3x8) = 26

What is proportion?

The ratio of two numbers a and b is given by a divided by b and represented by a/b or a:b. While the proportion is the relation between two ratios of a/b and c/d is represented by a:b::c:d or a/b=c/d.

Given that, there are 8 big fish for every 10 small fish, we need to find how many are there for 4 big fish for every.

We will solve this by using proportion,

Let the number of small fishes be x

Therefore,

8 / 10 = 4 / x

x = 5

Hence, there are 5 small fish for every 4 big fishes.

Answers

wouldn’t it be y=-4x+1
Answer:  y = -4x+1

========================================================

Explanation:

The two points on this line are (-1,5) and (0,1)

Let's use the slope formula

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

m = (1-5)/(0-(-1))

m = (1-5)/(0+1)

m = -4/1

m = -4

The slope is m = -4

If we started at (-1,5) and moved down 4 and to the right 1, then we arrive at (0,1). The motion "down 4, right 1" is directly tied to the slope -4 since -4 = -4/1 = rise/run

The y intercept is b = 1 since this is the location where the graph crosses the y axis.

With m = -4 and b = 1, we go from y = mx+b to y = -4x+1

y = 6x - 29
y = 6x + 19
y = 6x - 19
y =6x + 29

Answers

Answer:

[tex]y=6x-19[/tex] is the function which best

represented by this graph.

The graph is also attached.

Step-by-step explanation:

As the point-slope form is

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope

Given

m = 6 and the point (4, 5)

substituting the values in the point-slope form

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y - 5 = 6 (x - 4)[/tex]

[tex]y - 5 = 6x-24[/tex]

[tex]y=6x+5-24[/tex]

[tex]y=6x-19[/tex]

Therefore, [tex]y=6x-19[/tex] is the function which best

An independent study commissioned by the stadium showed that running a cable TV ad 5 times daily for a week generated 1,200 ticket sales. The stadium wants to sell out an upcoming show, which requires the sale of 13,200 tickets. How long should the stadium run the cable ad in order to reach this target?

Answers

Answer

I think 55 times

Step-by-step explanation:

13,200/1,200 = 11

5/1200 =  x/13,200

so if 1,200*11=13, 200 then 5*11= 55.

btw , could u give me the brainliest if i am right?

The total time the stadium runs the cable ad in order to reach this target is 11 days and this can be determined by using the unitary method.

Given :

Running a cable TV ad 5 times daily for a week generated 1,200 ticket sales. The stadium wants to sell out an upcoming show, which requires the sale of 13,200 tickets.

The following steps can be used in order to determine the total times the stadium run the cable ad in order to reach this target:

Step 1 - The unitary method can be used in order to determine the total times the stadium runs the cable ad in order to reach this target.

Step 2 - According to the given data, running a cable TV ad 5 times daily for a week generated 1,200 ticket sales.

Step 3 - If running TV ad 5 times daily sales 1200 tickets then to sell 13200 tickets the total times the ad is running is:

[tex]=\dfrac{13200}{1200}\times 5[/tex]

= 55 times

Step 4 - Now, if 5 times ad running in one day then 55 times ad running in:

[tex]=\dfrac{55}{5}\times 1[/tex]

= 11 days

What is the value of x in the figure?

Answers

Answer:

Step-by-step explanation:

You need to set up a proportion.

(21 - 15) / 21  = 4/(x + 4)

6 / 21 = 4/(x + 4)

2/7 = 4/(x + 4)

2(x + 4) = 7*4

2x + 8 = 28

2x + 8-8= 28 - 8

2x = 20

x = 20/2
