Solve this system of equations by graphing. First graph the equations, and then type the solution. y=2x+2 y=x–2
Solution:
The equation of a straight line is in the form y = mx + b, where m is the slope of the graph and b is the y intercept (value of y when x = 0). To graph the line, online geogebra graphing calculator was used for plotting the two graphs by writing the equation of the graphs.
After plotting the two graphs, the intersection of the two lines should be traced to get the x coordinate and y coordinate of the point. This point is the solution of the two graph equations, hence:
The solution = (-4, -6)
Answer:
(-4-6)

Polynomials are closed under an operation if it produces a polynomial.
5x⁴, x² + 2x + 1 and x³ - 10x³ + 28x - 15
are all polynomials of x.
x - 3 + (-3)/(x - 2) is not a polynomial because x can be found in the denominator of a fractional term.

Answers
Answer:
the volume at 606k is 2.22....the third one
Step-by-step explanation:
v1=1.00 t1=273 v2=? t2=606
v1/t1=v2/t2
1.00/273=v2/606
1.00×606=273v2
606=273v2
606/273=v2

Which of the following shapes are rectangles ? Please choose 2 correct answers !!!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!
Answers
Answer:
Hello there! Your answer would be D and A
Step-by-step explanation:
I cant see A but as I go through all the others I get A. You know that a rectangle has 4 sides like a quad. but each of the opposite sides has to be equal. So you can see that D is without needing to look closer. It gets harder after that. We know that C is not one because none of the sides are even. Now there is B and A if you turn your computer/paper you will see that B is a square. So because of that, I think that A is a rectangle. :]
The shapes that present the rectangle will be B and D.
What is a quadrilateral?The quadrilateral has four sides and four angles. The sum of internal angles is 360 degrees.
If the opposite sides of the quadrilateral are parallel then the quadrilateral is known as a parallelogram.
And if all the angles of the parallelogram will be equal. Then the parallelogram will be known as a rectangle.
It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.
The shapes that present the rectangle will be B and D.

The expression represents the number of comic books a friend has is F = 3c + 5.
What is an expression?A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
A statement expressing the equality of two mathematical expressions is known as an equation.
As per the given,
A friend has 5 more than triple c
Suppose a friend has an "F" number of comic books then,
F = 3c + 5
Hence "F = 3c + 5 is an expression that indicates how many comic books a friend owns".

A car covers a distance of 60 km in 3 hours. However, for the first 40 km it travels 16 km/hr. At what speed must it travel for the rest of the distance in order to complete the journey on time?
Answers
Answer:
40 km/hr
Step-by-step explanation:
Given that:
Total distance covered in 3 hours = 60km
Speed during first 40 km = 16km/hr
Hence, time spent during the first 40 km ;
Recall:
Time = distance / speed
Time = 40 / 16
Time = 2.5 hours
Hence, speed required to cover the remaining (60 - 40) = 20km in (3 - 2.5) hours =0.5 hours
Speed = distance / time
Speed = 20 / 0. 5
Speed = 40 km / hr
