Can you find the grey area please
1 answer:
First, write the equation of the line.
<u>Let's find the y-intercept.</u>
- => y = mx + b
- => y = mx + 5
Now, let's find the slope.
- My chosen points: (1,2) and (-1,2)
<u>Finding the slope:</u>
- Rise/Run = -3/1 = -3
Our equation: y = -3x + 5
Now, let's <u>change</u> the sign to <u>"≤"</u> because that will tell us the area of the <u>gray region.</u> If we were using the sign <u>"≥"</u>, that would find the area of the <u>blue region.</u>
Linear inequality = <u>y ≤ -3x + 5</u>
Option B is correct.

Answer:56.8 inches
Step-by-step explanation:
For perimeter we must find the lengths of the 2 diagonal sides of the triangle which are the same because it is isosceles.
the triangle is cut directly in half so both halves of the base are 17/2
17/2 = 8.5
solve through pythagoren theorum
altitude^2 + (half of base)^2 = (diagonal length)^2
18^2 + (8.5)^2 = (diagonal length)^2
324 + 72.25 = (diagonal length)^2
396.3 = (diagonal length)^2
= diagonal length
diagonal length = 19.9
diagonal length + diagonal length + base = perimeter
19.9 + 19.9 + 17 = perimeter
56.8 inches = perimeter
