Answer:

m = - 3, c = - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

2y + 6x = - 4 ( subtract 6x from both sides )

2y = - 6x - 4 ( divide terms by 2 )

y = - 3x - 2 ← in slope- intercept form

with slope m = - 3 and y- intercept c = - 2

X + Y = 4
2x - 3Y = 6
Substitution or Elimination?

Answers

Answer:

(x, y) = (18/5, 2/5)

Step-by-step explanation:

x + y = 4

x = 4 - y

2x - 3y = 6

Substitution x

2x - 3y = 6

2(4 - y) - 3y = 6

8 - 2y - 3y = 6

-5y = 6 - 8

-5y = -2

y = 2/5

Substitution y

x = 4 - y

x = 4 - 2/5

x = 20/5 - 2/5

x = 18/5

(x, y) = (18/5, 2/5)

A ladder is leaning on a wall. The ladder is 45 feet long. The angle formed by the ladder and the ground is 32. How far does the ladder reach up the wall?

Answers

Answer:

23.85 feets

Step-by-step explanation:

Given that :

Length of ladder, L = 45 feets

Angle formed by ladder and ground, θ = 32°

Using trigonometry :

Sin θ = opposite / hypotenus

Opposite = h

Hypotenus = 45

Sin 32 = h / 45

0.5299192 * 45 = h

23.846366 = h

Hence, height of ladder = 23.85 feets

The surface area of the rectangular prism 158 square feet.

What is surface area?

The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any object is called the surface area.

The rectangular prism will have six faces. The surface area will be calculated as:-

Surface area = 2 ( 3x5) + 2 ( 8x3) + 2(8x5)

Surface area = 30 + 48 + 80 = 158 square meters

Therefore the surface area of the rectangular prism is 158 square feet.

Find the axis of symmetry and the vertex of the graph of f(x) = 4x^2-8x+3.

Answers

Answer:

(1, -1) and x= -1

Step-by-step explanation:

The vertex is (1, -1)

The parabola params are:

a=4, b=-8, c=3

v= −b/2a

- (−8)/ 2 · 4

Simplify

v=1 v=1

Plug in v=1 to find the y value

y=−1

Therefore the parabola vertex is

(1, −1)

The axis of symmetry is the line that passes through the vertex and focus.

Therefore, your axis of symmetry is

Fiona races BMX around a circular dirt course. If the radius of the course is 60 meters, what is the total distance Fiona covers in two laps of the race?

Answers

Answer:

753.6 meters

Step-by-step explanation:

Given :

Fiona races a BMX in a dirt course.

The course in circular in shape. The radius of the dirt course is 60 meters.

So the circumference of the dirt course is given by :

[tex]$C = 2 \pi r$[/tex]

   = 2 x 3.14 x 60

   = 376.8 meters

So the total outer distance of the circular dirt course is 376.8 meters.

Therefore, the total distance that Fiona covers in the two laps of the race is

= 376.8 + 376.8

= 753.6 meters
