Answer:
∠MEJ=25°
Step-by-step explanation:
step 1
Find the value of x
we know that
arc LJ+arc KM+arc KL+arc MJ=360° ----> complete circle
substitute the values
(4x+50)°+6x°+(x+10)°+4x°=360°
solve for x
(15x+60)°=360°
x=300°/15=20°
step 2
Find the measure of angle MEJ
we know that
The measurement of the external angle is the semi-difference of the arcs which comprises
∠MEJ=(1/2)[arc MJ-arc KL]
arc MJ=4(20°)=80°
arc KL=20°+10°=30°
substitute the values
∠MEJ=(1/2)[80°-30°]=25°
Answer:
A
Step-by-step explanation:
Argument
C and D are wrong right off the top. When you have x + 2 in synthetic division the divisor (2) must change signs.
B is incorrect because you don't change the signs of the polynomial that is being divided into. So that only leaves A and it is correct.
Summary
- Change the sign of the binomial doing the dividing (2 goes to - 2)
- Leave the polynomial's coefficients alone.
Answer:
y= -3x-16
Step-by-step explanation:
slope intercept form is written as y=mx+b. m is the slope, and b is the y-intercept. -3=m
we know that (-5,-1) is 5 points away from the origin, and that the slope is -3, so 5 times -3 equals -15. subtract 15 from -1 (y-coordinate) in order to get the y-intercept (when x=0).
So do you need it as a percent or a fraction?
