it equals an answer that answers the question
The graph is given below. Then the intersection point will be (-9, 11).
<h3>What is the linear system?</h3>
A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
An unknown number y is 20 more than an unknown number x.
The number y is also x less than 2.
The equations to find x and y are shown below:
y = x + 20 ...1
y = −x + 2 ...2
Add both equations, then we have
2y = 22
y = 11
Then put the value of y in equation 1, then we get
11 = x + 20
x = 11 - 20
x = -9
Then the intersection point will be (-9, 11)

Answer:
a trapezoid
Step-by-step explanation:
A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs
Characteristics of a trapezoid
It has 4 vertices and edges
If both pairs of its opposite sides of a trapezoid are parallel, it becomes a parallelogram
Area of a trapezoid = x (sum of the lengths of the parallel sides) x height
Perimeter = sum of lengths of sides of a trapezoid
Answer:
what are your options for select all that apply
Step-by-step explanation:
---------------------------------------------------------------------------
Irina:
---------------------------------------------------------------------------
Irina takes 7 hours to paint the room.
In 1 hour, Irina can paint 1/7 of the room.
---------------------------------------------------------------------------
Paulo:
---------------------------------------------------------------------------
Paulo takes 6 hours to paint the room.
In 1 hour, Paulo can paint 1/6 of the room.
---------------------------------------------------------------------------
Both paint together:
---------------------------------------------------------------------------
In one hour they can paint (1/7 + 1/6) of the room.
1/7 + 1/6 = 13/42
So, it takes 13/42 of the room takes 1 hour.
---------------------------------------------------------------------------
Find the number of hours
---------------------------------------------------------------------------
13/42 of the room = 1 hour
Whole room = 1 ÷ 13/42
Whole room = 1 x 42/13
Whole room = 3.23 hours
---------------------------------------------------------------------------
Answer: They need 3.23 hours to paint the room.
