Answer:
n = 6.2/-10.4=0.5962
Step-by-step explanation:
What is the value of n in the equation. we would make n the subject formula -1.2(2n+4)+6=-9+4(2n+1)
Opening the brackets,
-1.2×2n -1.2×4 + 6= -9 +4×2n + 4×1
-2.4n -4.8 +6 = -9 +8n + 4
-2.4n -4.8 +6 = -9 + 4 + 8n= -5+8n
Collecting like terms
-2.4n-8n = -5+4.8-6
-10.4n =-6.2
n = -6.2/-10.4= 0.5962
Let's check, put n= 0.5962 in the equation
-2.4n -4.8 +6 = -9 +8n + 4
Lefthand side
-2.4×0.5962-4.8+6= -0.230
Right hand side
-9+ 8× 0.5962 +4
=-9 +4.7696 +4
=0.230
Right hand side = left hand side
3x + 1 = 8
move +1 to the other side
sign changes from +1 to -1
3x+1-1= 8-1
3x= 7-1
divide by 3 for both sides to get x by itself
3x/3= 7/3
Answer:
x= 7/3 and x= 2 1/3
Answer:
Yes, No, No, No
Step-by-step explanation:
To decide whether the point lies on the circle, what you need to do it simply substituting the x and y values into the equation and check if it add up to be 25
(-5)² + 0² = 25, = RHS [Yes]
1² + (√7)² = 8, ≠ RHS [No]
(√21)² + (-3)² = 30, ≠RHS [No]
0² + 7² = 49, ≠RHS [No]
Any second part or anything else to look at?
