Answer:
Step-by-step explanation:
m = 3
(1 , 6)
y - y1 = m(x -x1)
y - 6 = 3(x - 1)
y - 6 = 3x - 3
y = 3x - 3 + 6
y = 3x +3
Standard form:
-3x + y - 3 = 0

Complete Question:
Jocelyn said that the triangle below is not a right triangle. Her work is shown below. Explain what she did wrong, and show Jocelyn the correct solution.
We need to check if 27² + 45² = 36² is a true statement. The left side of the equation is equal to 2,754. The right side of the equation is equal to 1,296. That means 272 + 452 = 362 is not true, and the triangle shown is not a right triangle
Answer/Step-by-step explanation:
Jocelyn used a wrong equation and statement.
Here's what she should have stated and done.
Using the converse of Pythagorean Theorem, which says that a triangle with sides a, b, and c is a right triangle if it satisfy the statement: a² + b² = c².
Where, c is the hypotenuse which is the longest leg. While a and b are the side lengths of the other two legs.
Therefore, in this case,
c = 45
b = 27
a = 36
Thus, what we need to check to be true would be:
36² + 27² = 45² (this is where Jocelyn made a mistake. Jocelyn wrote 27² + 45² = 36² rather)
Let's check if it's true.
2,025 = 2,025 (this is true)
Therefore, the triangle is a right triangle.

Connor and Angie helped take attendance during their school's practice
fire drill. Connor counted 470 in attendance and Angie counted 479. The
actual attendance was 470. What is the percent error? (ROUND TO THE
NEAREST TENTH.) *
0.019
1.2%
1.9%
12%
Answer: 1.9%
Step-by-step explanation:
The percent error formula is [tex]\frac{accepted-experimental}{accepted}[/tex] so input our values also keep in mind when we do percent error we use absolute error which means no negative percentages so 470-479/470= -9/470 or 9/470
as a decimal 9/470 is 0.019 or 1.9% so the answer is 1.9%

Answer:
9x+2
Step-by-step explanation:
It's a simple problem, to find the perimeter, add a+b+c. In this case, it's with binomials, but it follows the same idea.
(2x+2)+(3x+1)+(4x-1)
2x+2+3x+1+4x-1
Combine like terms.
2x+3x+4x=9x
2+1-1=2
Left with 9x+2 as your perimeter binomial.
