First we must take the 4 to the other side: giving us -2x = 6.
Then we take the -2 to the other side:
X = 6/-2
X = -3
Answer:
7/10 pi (radians)
Step-by-step explanation:
The formula for sector area is (angle * r^2)/2
140pi = angle*r^2/2
multiply both sides by 2
280pi = angle * r^2
r = 20 cm (substitute)
280pi = angle * (20)^2
280pi = angle * 400
Divide both sides by 400
7/10 pi = angle
1cg=10mg, so 90cg95mg=90*10+95=995 mg. 7g=7*1000=7000mg, 12cg=12*10=120mg, so 7g 12 cg 18 mg =7000+120+18=7138mg, so <span>90 cg 95 mg + 7g 12 cg 18 mg=14138mg=14000mg+100mg+38mg=14g1cg38mg.</span>
Answer:
C) Both (1 , 11) and (-1, -5)
Step-by-step explanation:
y = 8x + 3
Plugin x = 1 and y = 11 in the equation
11 = 8*1 + 3
11 = 8 +3
11 = 11
So, (1 , 11) is a solution.
Plugin x = -1 and y =-5 ,
-5 = 8*(-1) + 3
-5 = -8 + 3
-5 = -5
So, (-1 , -5) is also a solution
