Answer:
5 in
Step-by-step explanation:
AC = the diameter
FA = the radius
diameter=2*radius
10=2*FA
FA=10/2
FA=5 in
Answer:
x=0
y=-21/7
Step-by-step explanation:
Let the two unknown be x and y
x+y=-7...(1)
x-y=14...(2)
From (1) make x the subject of formula
x=-7-y...(3)
Substitute (3) into (2)
-7-y-y=14
-7-2y=14
Add 7 to both sides
-2y=21
Add both sides by-2
y=-21/2
Substitute the value of y into (3)
x=-7-(-21/2)
x=-7+21/3
Lcm
x=-21+21/3
x=0/3
x=0
Answer:
Step-by-step explanation:
1) Write 8x+14 as 2(4x+7) and now multiply by 1/2 so that we get 4x+7
2)Subtract 7 from both sides
4x+7=39
-7 -7
4x=32
3) Divide by 8
x=8
Thus we get x=8 as answer
So reasons are
i) Distributive property
ii) Subtraction property of equality
iii) Division property of equality
Answer:
-4
Step-by-step explanation:
y = -4x + 6 is the equation and -4 is the slope
