68 is the 22nd term of the following sequence.

<u>Step-by-step explanation:</u>

  • The given sequence is with the same common difference between the two consecutive number in the series thus it is said to be the  Arithmetic progression ( AP).
  • For finding the nth term in the AP we have a formula tn = a + (n-1) × d
  • Here a is the first term , n is the number of the term to be founded and d is the common difference between the two consecutive number in the series.
  • Thus here tn = 5 + ( 22 - 1 ) × 3.
  • On subtracting we get tn = 5 + (21 ) × 3
  • On multiplying we get tn = 5 + 63
  • After adding we get tn = 68. It is the 22nd term in the given series.

Solve the Quadratic Equation by factoring. 3r^2-16r-7=5
Alex Ar [27]
So first set one side to zero

subtract 5 from both sides
3r^2-16r-12=0
factor

to find the factor in
ax^2+bx+c form when a>1
multiply a and c together
find what 2 numbers add up to b and multiply to ac so

a=3
b=-16
c=-12

ac=3 times -12=-36
factors that add up to -16
2 and -18 is the answer since 2 times -18=-36 and 2-18=-16 so

split the middle number up
3r^2-16r-12=0
3r^2-18r+2r-12=0
group
(3r^2-18r)+(2r-12)=0
factor out common factors
(3r)(r-6)+(2)(r-6)=0
reverse distribute (ab+ac=a(b+c) so
(3r+2)(r-6)=0

set each to zero
r-6=0
add 6
r=6


3r+2=0
subtract 2
3r=-2
divide 3
r=-2/3


r=6 or -2/3

2x+y=-4 if y=mx+b and m is the slope, state the slope
Tamiku [17]

Answer: The slope is -2x. The slope intercept form is Y = -2x - 4

Step-by-step explanation:

Get y by itself just like you are solving for it, all you need to do is subtract 2x

y = -2x - 4
