Answer:
<h2>
3x + 5y = 12 </h2>
Step-by-step explanation:
3x + 5y = 7 {subtract 3x from both sides}
5y = -3x + 7 {divide both sides by 5}
y = -³/₅x + ⁷/₅ ← slope-intercept form
y=m₁x+b₁ ║ y=m₂x+b₂ ⇔ m₁ = m₂
{Two lines are parallel if their slopes are equal}
y = -³/₅x + ⁷/₅ ⇒ m₁ = -³/₅ ⇒ m₂ = -³/₅
(-1, 3) ⇒ x₁ = -1, y₁ = 3
The point-slope form:
y - 3 = -³/₅(x - (-1))
y - 3 = -³/₅(x + 1) {myltiply both sides by 5}
5y - 15 = -3x - 3 {add 3x to both sides}
3x + 5y - 15 = - 3 {add 15 to both sides}
<u>3x + 5y = 12</u>
Answer:
Answer D, Construct the bisector of corner J
Step-by-step explanation:
These are the steps:
1. Bisect one of the angles.
2. Bisect another angle.
3. Where they cross is the center of the inscribed circle, called the incenter.
4. Construct a perpendicular from the center point to one side of the triangle.
From point 1. we can see that the answer must be Answer D, Construct the bisector of corner J
The answer to the question is 1.03
Answer:
25.82 is my answer in two decimal places
numbers above 4 are rounded to add 1
while numbers below 4 are rounded to add zero
from the last 5... round to add 1 to 2 before it
then the 2 +1 becomes 3
the 3 is rounded to add zero to 1, before it
then 1 +0 is still 1
then 1 is rounded to add zero to 6
then 6+0 is still 6
6 is then rounded to add 1 to 1
then 1+1 becomes 2, which is rounded to add zero to 9
then 9 is rounded to add 1 to 8
the the 8+1 becomes 9, which is rounded to add 1 to 3
then 3+1 becomes 4, which is rounded to add zero to 2.
stops here, since it's to two decimal places
answer is 25.82
