Black: y = 3x + 2
B. You find the ordered pair (x, y) that is a solution for both functions ( find the point where the two lines cross)
C. There’s two ways you can solve algebraically (using the equations); substitution and elimination. I don’t know which you need to use to answer but feel free to use my notes on how to do substitution for help. I don’t really have any on elimination ( it’s so easy you don’t even really need notes) or I would use them to explain.

Matthew had to make a bridge for his math class. It had to be at least 1 1/2 feet long. Harold made a bridge that was 2/13 times as long as Matthew’s. Write and solve an equation that will help you figure out how long Harold’s bridge was. Explain the steps you took to solve the problem.
Answers
Answer:
Step-by-step explanation:
2 / 13 = 15.38% or 15.38..... If Matthew's bridge is 1 1/2 feet long which is 45.72cm then 45.72 + 15.38 = 61.1cm > convert into feet > 1.55194 ft.

B. -144; no real roots
C. 0; one real root
D. 0; two real roots
Answers
Discriminant and the number of real roots for this equation are 0, one real root.
What is discriminant?Discriminant of a polynomial in math is a function of the coefficients of the polynomial.
The discriminant of a quadratic equation ax2 + bx + c = 0 is in terms of its coefficients a, b, and c. i.e.,
Discriminant = [tex]\sqrt{b^{2} -4ac}[/tex]
Given equation
[tex]4x^{2} +12x+9 = 0[/tex]
Discriminant = [tex]\sqrt{b^{2} -4ac}[/tex]
= [tex]\sqrt{12^{2}-4(4)(9) }[/tex]
= [tex]\sqrt{144-144}[/tex]
D = 0
Therefore, number of real roots is one.
Hence, discriminant and the number of real roots for this equation are 0, one real root.

The width of a rectangular room is 80% of its length. If the length of the room is 20 meters, what is the area of the room? A= length x width
Answers
Answer:320ft^2
Step-by-step explanation:
80% of 20 is 16, because 80% is 4/5 and 20 divided by 5 is 4, multiplied by 4 is 16. Area is L x W, so 16 times 20 is 320, and don't forget unit of measurement, ft^2 for area
Length x width = area
