What is the y-intercept?

(0, –5)
(0, –2)
(0, 2)
(0, 4)

Answer:

just go down negative 7 on the y int and that's ur starting point, then go down -1 and over 4 to the right, repeat this step 2 or 3 times then draw ur line.

The line with the equation y= - 1/4x -7 graph is shown below.

Suppose the considered function whose graph is to be made is

f(x)

The values of 'x' (also called input variable, or independent variable) are usually plotted on horizontal axis, and the output values

f(x)

are plotted on the vertical axis.

They are together plotted on the point

(x,y) = (x, f(x))

This is why we usually write the functions as:

y = f(x)

Given;

y= - 1/4x -7

Now, the graph of the function is given in the image.

Answer:

5.0090, 5.05, 5.054, 5.5

Answer:

Step-by-step explanation: (Equation 2) = 12(-12+9y/4) - 10y = -8

-144+108y/4 - 10y = -8

-144 + 108y - 40y/4 = -8

-144 + 108y - 40y = -32

108y - 40y = -32+144

68y = 112

Y= 1.64

2-4x+9y=14

12x-10y= -8

2-14+9y = 4x

-12 + 9y = 4x ( equation 3)

(Put in equation 2)

Answer:

-4x + 9y = 14 answer is x = [tex]\frac{9}{4}y+ \frac{-7}{2}[/tex]

12x - 10y = -8 answer is x = [tex]\frac{5}{6}y +\frac{-2}{3}[/tex]

Step-by-step explanation:

solve for x

-4x + 9y = 14

add -9y to both sides

-4x + 9y + -9y = 14 + -9y

-4x = -9y + 14

divide both sides by -4

-4x/-4 = -9y + 14/-4

Anwser

x = [tex]\frac{9}{4}y + \frac{-7}{2}[/tex]

solve for x

12x - 10y = -8

add 10y to both sides

12x - 10y + 10y = -8 + 10y

12x = 10y -8

Divide both sides by 12

12x/12 = 10y - 8/12

Anwser

x = [tex]\frac{5}{6}y +\frac{-2}{3}[/tex]

Step-by-step explanation:

Answer:

a = 3, b = 1, c = - 3

Step-by-step explanation:

Substitute n = 1, 2, 3 into the n th term

a + b + c = 1 → (1)

4a + 2b + c = 11 → (2)

9a + 3b + c = 27 → (3)

Subtract (1) from (2) term by term to eliminate c

Subtract (2) from (3) term by term to eliminate c

3a + b = 10 → (4)

5a + b = 16 → (5)

Subtract (4) from (5) term by term to eliminate b

2a = 6 ( divide both sides by 2 )

a = 3

Substitute a = 3 into (4) and evaluate for b

3(3) + b = 10

9 + b = 10 ( subtract 9 from both sides )

b = 1

Substitute a = 3, b = 1 into (1) and evaluate for c

3 + 1 + c = 1

4 + c = 1 ( subtract 4 from both sides )

c = - 3

Then a = 3, b = 1 and c = - 3

The measure of a, b and c is  3, 1 and - 3 respectively.

A quadratic sequence is a sequence whose nth term is given by the general formula -

A{n} = an² + bn + c.

Given are the 4 terms of the quadratic sequence as 1, 11, 27 and 49.

Now, we can the following equations as -

A{1} = a + b + c = 1

a + b + c = 1

c = 1 - a - b              ........ Eq[1]

A{2} = 4a + 2b + c = 11

4a + 2b + c = 11

c = 11 - 4a - 2b           ........ Eq[2]

A{3} = 9a + 3b + c = 27

9a + 3b + c = 27

c = 27 - 9a - 3b               ........ Eq[3]

A{4} = 16a + 4b + c = 49

16a + 4b + c = 49

c = 49 - 16a - 4b             ........ Eq[4]

Equate Eq[1] and Eq[2] -

1 - a - b  =  11 - 4a - 2b  

1 - 11 = - 4a - 2b + a + b

- 10 = - 3a - b

3a + b = 10                ........... Eq[5]

Equate Eq[3] and Eq[4] -

27 - 9a - 3b = 49 - 16a - 4b  

- 9a - 3b + 16a + 4b = 49 - 27

7a + b = 22          .......... Eq[6]

We can write -

7a + 10 - 3a = 22

4a + 10 = 22

4a = 12

a = 3

and

b = 10 - 3a

b = 10 - 9

b = 1

At last -

c = 1 - a - b

c = 1 - 3 - 1

c = - 3

Therefore, the measure of a, b and c is  3, 1 and - 3 respectively.

Answer:i need points

Step-by-step explanation:

The cost to buy the rectangular window is $ 912.60

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

Let the cost to buy rectangular window be represented as A

Now , the value of A is

The length of the rectangular window be L = 10 feet

The width of the rectangular window be W = 13 feet

Let the cost per square foot be c = $ 7.02

Area of Rectangle = Length x Width

Substituting the values in the equation , we get

Area of rectangular window = 10 x 13 = 130 feet²

The cost to buy the rectangular window A = 130 x cost per square foot

Substituting the values in the equation , we get

The cost to buy the rectangular window A = 130 x 7.02

The cost to buy the rectangular window A = $ 912.60

Hence , the cost to buy the window is $ 912.60

Answer:

x=0

Step-by-step explanation:

We can first add 49 to both sides to get (x+7)^2=49

We can then take the square root of both sides and get x+7=7

Subtract 7 to both sides and you get x=0

Answer:

[tex]x=-14\text{ and } x=0[/tex]

Step-by-step explanation:

We are given:

[tex](x+7)^2-49=0[/tex]

And we want to solve for x.

First, we can add 49 to both sides:

[tex](x+7)^2=49[/tex]

Now, we can take the square root of both sides. Since we are taking an even root, we will need plus-minus. Hence:

[tex]x+7=\pm\sqrt{49}[/tex]

Evaluate:

[tex]x+7=\pm7[/tex]

Subtract 7 from both sides:

[tex]x=-7\pm7[/tex]

So, we have two solutions:

[tex]x=-7+7\text{ and } x=-7-7[/tex]

Evaluate:

[tex]x=0\text{ and } x=-14[/tex]

So, from least to greatest, our solutions are:

[tex]x=-14\text{ and } x=0[/tex]

Answer: Twenty one meeters!!

Answer:  The area of the path running around the inside edge of the field is  731.2 m²

If the path is across the middle of the field, the area of that path is about 245m²

Step-by-step explanation:

The radius of the field is 35m, subtracting 3.5 from that leaves the radius of the inside edge of the path at 31.5 m

The area of the path will be the difference between the two areas.

π × 35² = 3848.45

π × 31.5² = 3117.25

3848.45 - 3117.45 = 731.2

If the path is across the middle of the field, use the diameter, 70m,  times the width of the path, 3.5m,  to find the area of that path: 245m²
