A system of equations is created by using the line represented by2x+4y=0And the line represented by the data in the table below
What is the X value of the solution to the system if x -1 and y is 8

Answers

Answer:

x = 2

Step-by-step explanation:

From the data, we obtain the slope :

-1, 8 ; 3, - 4

Slope = Rise / run

Rise = y2 - y1 = (-4 - 8) = - 12

Run = x2 - x1 = (3 - (-1)) = 4

Slope, m = - 12 / 4 = - 3

Recall:

Equation of line :

y - y1 = m(x - x1)

y - 8 = - 3(x + 1)

y - 8 = - 3x - 3

y = - 3x - 3 + 8

y = - 3x + 5

Substituting y = - 3x + 5 into the equation 2x+4y= 0

2x + 4(-3x + 5) = 0

2x - 12x + 20 = 0

-10x = - 20

x = 2

Answers

Answer:

(2x + 5)(3x - 7), (x + 4)(x - 2)

Step-by-step explanation:

a = 6, b = 1, c = -35

? × ? = ac = 6 × -35 = - (2 × 3 × 7 × 5)

? + ? = b = 1

3 × 5 -(negative sign from above) 2 × 7 = 15 - 14 = 1 = b

[tex]\frac{1}{6}(6x + 15)(6x + (-14))[/tex]

= [tex]\frac{1}{6}(3)(2x + 5)(2)(3x - 7)[/tex]

= [tex](2x + 5)(3x - 7)[/tex]

a = 1, b = 2, c = -8

? × ? = ac = 1 × -8 = -(2 × 2 × 2) = 4 × -2

? + ? = b = 2

4 + (-2) = 2 = b

[tex]\frac{1}{1}(1x + 4)(1x + (-2))[/tex]

= [tex](x + 4)(x - 2)[/tex]

The two triangles are similar. Given that a = 7, b = 17, and c = 23, find the value of x. Round your answer to the nearest hundredths place.

O 10 < 1.85.1 +0.50
O 10 > 1.852 +0.50
O 10 > 0.503 +1.85

Answers

Answer:

[tex]10 > 1.85 + 0.5m[/tex]

Step-by-step explanation:

Price of the scooter:

Fixed price of $1.85 to activate plus $0.50 for each mile. This situation can be represented by a linear function, and it is given by:

[tex]P(m) = 1.85 + 0.5m[/tex]

Mikael has a gift card for $10 and he can not spend more on the scooter.

The spendings have to be less than 10. So

[tex]10 > P(m)[/tex]

[tex]10 > 1.85 + 0.5m[/tex]

A bridge is built in the shape of a parabolic arch. The bridge has a span of feet and a maximum height of feet. Choose a suitable rectangular coordinate system and find the height of the arch at distances of​ 10, 30, and 50 feet from the center.

Answers

Answer:

Height of the arch at distances of​ 10, 30, and 50 feet from the center is as follow:

Put x = 10 we get

the value of y = 0.695

Put x = 30

the vale of y = 6.26

Put x = 50

the value of y = 17.37

Step-by-step explanation:

The prabolic arch for bridge has span of 120 feet and height f 25 feet. The rectangular corordinate system is

such as

height = h = 25

Distance = x

(x-h) = -4a(y-k)

x² = -4ay

60 = -4a(-25) and

where the value of a =36

therefor the parabolic arch is

x = -144y

For distance of 10 , 20 and 30 let take the feet from center then we have

put x = 10 we get

10² = -144 y

100 / 144 = y

the value of y = 0.695

Put x = 30

30² = -144y

30/144 = y

the vale of y = 6.26

Put x = 50

50² = -144 y

50/144 = y

the value of y = 17.37

For that you can use the foil method to check the choices given are equal to x2+9x-22. Foil stands for First term Outside term Inside term Last term. We can directly cross off a because it


doesn’t equal to x2+9x-22. Let’s check choice c you get x2-2x-11x+22 that doesn’t give us x2+9x-22 . You can also directly cross out choice d . Only b is the correct answer.
