Answer:
y = x + 1
Step-by-step explanation:
We can see the line is linear so we can write the equation using y = mx + b. The components of the equation are m = slope and b = y-intercept. We can see from the graph that the y-intercept is 1 as the graph crosses the y axis at y = 1 and if we do 
or 
, we can plug in the y-intercept's coorinates and the point in red's coordinates to get the slope of 1. Therefore, the equation would be y = 1x + 1 or y = x + 1
Y > x
y = 2(3+x)
y = 3x-2
------------------------------
2(3+x) = 3x-2
2(3+x) - (3x-2) = 0
6 + 2x -3x + 2 = 0
8 -x = 0
x = 8
---------------------------
y = 2(3+x) = 2(3+8) = 22
y = 3x-2 = 3*8 -2 = 22
----------------------------------
x = 8 ; y = 22
Problem 3
Circumference = pi*diameter
C = pi*d
C = 3.14*7.6
C = 23.864
C = 23.9
<h3>Answer: 23.9 cm</h3>
=======================================
Problem 4
A = area of square
A = side*side
A = 8*8
A = 64 square cm
B = area of circle
B = pi*r^2
B = 3.14*(5.5)^2 .... radius = 5.5 is half of diameter = 11
B = 94.985
C = area of shaded region
C = B - A
C = 94.985 - 64
C = 30.985
<h3>Answer: 30.985 square cm</h3>
=======================================
Problem 5
diameter = 6
radius = 3
area = pi*radius^2
A = pi*r^2
A = pi*3^2
A = 9*pi
A = 9*3.14
A = 28.26
<h3>Answer: 28.26 square millimeters</h3>
Answer:
-26
Step-by-step explanation:
sub in the x value
-4+3-(2(-5)+5)^2
-4+3-(-10+5)^2
-4+3-(5)^2
-1-25
-26
