Y = 2x + 4 2x - y = 6

Mathematics
1 answer:
Oxana [17]3 years ago
3 0

Answer:

y < 2x + 4  is a dashed line that crosses the y - axis at (0,4) and is shaded below the line.

-3x - 2y ≥ 6 when solved for y: y ≤ -3/2x - 3

is a solid line that crosses the y-axis at (0, -3) and is shaded below the line

Problem 2:

first inequality is mentioned in problem 1

second inequality: 2x - y ≤ 4 when solved for y:  y ≥ 2x - 4

is a solid line that crosses the y- axis at (0, -4) and is shaded above the line

It is parallel to the first line because they have the same slope

Aleks04 [339]

Answer:

√308 or 17.5

Step-by-step explanation:

c^2=a^2+b^2

c^2-a^2=b^2

Substitute

18^2-4^2=b^2

324-16=b^2

b^2=308

b=√308 or b=17.5

A cube has an edge lengths of 5 cm. A rectangular prism has dimensions of 5 cm, 25 cm, and 1 cm. Which of the following statemen
murzikaleks [220]

The volume of cube and rectangular prism are same. Option B.

Step-by-step explanation:

Given,

The length of the edge of the cube (a) = 5 cm

The dimension of rectangular prism (l×b×h) = 5 cm×25 cm×1 cm

To find the relation between the volume of cube and rectangular prism.

Formula

The volume of a cube = a³ cube cm

The volume of rectangular prism = l×b×h cube cm

Now,

The volume of a cube = 5³ cube cm = 125 cube cm

The volume of rectangular prism = 5×25×1 cube cm = 125 cube cm

Hence,

The volume of cube and rectangular prism are same.

PLZ HELP ME I NEED THIS FAST WILL GIVE BRAINLIEST
Bas_tet [7]

Step-by-step explanation:

The formula the amusement parc use is  100y-39000=55(x-800)

The slope intercept form of a function is wriiten generally as:

y = mx+c

  • m is a slope
  • c is a constant and represents the y-intercept
  • x is a variable
  • y is the input of the function

Let's rewrite our equation in the precedent form

  • 100y-39000 = 55(x-800)
  • 100y -39000 = 55x-44000    add 39000 in both sides
  • 100y-39000+39000 = 55x-44000+39000
  • 100y = 55x-5000            divide both sides by 100
  • y = 0.55x-50

The slope intercept form of this equation is:

y= 0.55x-50
