What is 4x+y=4 x+y=-2 ?

Mathematics
1 answer:
Pani-rosa [81]2 years ago
6 0

Answer: x = 2, y = -4

<u>Step-by-step explanation:</u>

4x + y = 4     -->      y = 4 - 4x

Substitute "y" with 4 - 4x into the other equation and solve for "x":

x + y = -2

x + (4 - 4x) = -2

      4 - 3x = -2

         - 3x = -6

             x = 2

Substitute "x" with 2 into one of the original equations to solve for "y":

x + y = -2

(2) + y = -2

       y = -4

If you rotate a equilateral triangle by a side, what is the name of the resulting 3d shape
Katyanochek1 [597]
<h2> ☞ANSWER☜</h2>

<h3>3D shapes</h3>
  • Cube Cuboid
  • Sphere Square-based pyramid
  • Cylinder Triangular prism
  • Pentagonal pyramid Hexagonal prism

<h2> ☞EXPLANATION☜</h2>

<em><u>A solid of revolution is a three-dimensional figure obtained by rotating a two-dimensional figure (or curve) around a straight line (called the axis) that lies in the same plane. ... Since the triangle's interior is shaded, it creates the interior of the cone, creating a solid figure.</u></em>

<em><u>Three dimensional shapes are obtained by rotating the two dimensional shapes. When a circle is rotated we get sphere; when a triangle is rotated we get cone; when rectangle or square is rotated we get cylinder</u></em>

Joe earns $425 a week for working 40 hours and an additional $20 an hour for each hour over 40. Last week, Joe made $485. Write
Tasya [4]

Answer:

Joe worked 3 hours overtime.

Step-by-step explanation:

Let t = number of hours overworked

425 + 20 × t = 485

425 + 20t = 485

20t = 485 - 425

     = 60

\frac{20t}{20} = \frac{60}{20}

t = 3

\therefore Joe worked 3 hours over time.

Hope this helps :)

I need to solve the three representations (the table, rule/equation, and the graph)
Hitman42 [59]
Figure #5 shows 5 squares which I would assume means (5, 5)
In the table you have the point (3, 7)
From this you can find the slope: (7 - 5)/(3 - 5) = -1 
Completions of table:
x     y
0   10
1     9
2     8
3     7
4     6
5     5
6     4

Rule/Equation:
y = -x + 10

Graph: Plot the ordered pairs from the table

There are 10 total marbles and three are pink. So you are to determine the probability of choosing a pink marble, placing it back in the bag and choosing another pink marble.
The probability of choosing a pink marble is # of pink marbles to # of all marbles which is 3/10. Since we place the marble back in the bag, the probability is the same for the second time.
To determine the probability of both occurrences, we need to multiply 3/10 x 3/10 which is 9/100. This can be written as 9:100 as a ratio.
