StartFraction 3 pi Over 4 EndFraction radians
Step-by-step explanation:
Pi radians is equal to 180°
Given the minor arc angles as 135°, change this value to pi radians
180° =π radians
135° = ?
Cross multiply
135° * π radians / 180°
=135/180 * π radians
=3 π/4 radians

Plot the intercepts:
y=-1
x=?
to find the x intercept, you dont solve the equation as it is solved in the slope-intercept form. instead, you simply plug in 0 for y:
0=1/4x-4
0=1/4x-4+4
4=1/4x
4/1/4=1/4x
1/4=0.25
x=16
revise:
y=(0, -1)
x=(16,0)
graph the slope for y=-1/2x-1: start from say point (0,-1)
graph the slope for y=1/4x-4: start from say point (16,0) ; you can just ise the intercept (0,-4) since the graph is diluted small...anyways
the points intersect at (4, -3) so thats the solution to the equations
NOTE: when graphing slopes that are negative either the numerator or the denominator can be graphed negative. so I graphed the first equation with the numerator as the positive and the denominator as the negative : rise= 1 ; run: -2. once i got to the end of the provided graph i started from the -1 y-intercept again and graphed the equation using: rise=-1; run=2
*graphing messes me up, too*
Answer:
(-4,16)
Step-by-step explanation:
1/2x+18=5/2+26
1/2x=5/2x+8
-2=8 divided by -2
Equals x=-4
Plug in -4 in one of the equations
1/2(-4)=18= 16
3/20 left to read. If you start 85/100 you take 100-85 and get 15, then you end up 15/100 which reduces to 3/20.
Answer: y = ¹/₂x + 2
Step-by-step explanation: This is slope-intercept form. y = mx + b
m is the slope. Rise/run
The difference in y-values is the rise. The difference in x-values is the run.
Look for places where the graphed line intersects the grid. Count the squares. Here, the graphed line rises 1 square as it runs 2 squares.
b is the y-intercept. Here, that is 2
