Answer:
x = -2
x=-12
Step-by-step explanation:
5 | x+7| +14 = 39
Subtract 14 from each side
5 | x+7| +14-14 = 39-14
5 | x+7| = 25
Divide each side by 5
5 | x+7| /5 = 25/5
| x+7| = 5
Make two equations, one positive and one negative
x+7 =5 x+7 = -5
Subtract 7 from each side
x+7-7 = 5-7 x+7-7 = -5-7
x = -2 x=-12
Answer:
Step-by-step explanation:
lateral area=πr²h=π×3²×6=54π sq. yards
surface area=2πr²+πr²h=2π×3²+54π=18π+54π=72π sq. yards
Answer:
x=20
Step-by-step explanation:
log3(4x+1) = 4
Raise each side to the base of 3
3^log3(4x+1) = 3^4
4x+1 = 3^4
4x+1 = 81
Subtract 1 from each side
4x+1-1 = 81-1
4x= 80
Divide by 4
4x/4 = 80/4
x = 20
<span>F(x) = x + 3
y = x + 3
y - 3 = x
so
</span><span>F ^-1(x) = x - 3
</span><span>The zero of F ^-1(x) is -3
answer is
</span><span>-3</span>
Step-by-step explanation:
2/5 is closest to 1/2
5/8 is closest to 1/2
1/2 + 1/2 = 1
