Find the 82nd term of the arithmetic sequence -10,6,22
Answer:
a(82) =1286
Step-by-step explanation:
a(n) = a +(n-1)d
a=-10
d=6+10=22-6=16
°.° a(n) = -10 +(n–1)16
a(82) = -10 +(82–1)16
=-10+(81x16)
=1286

What is the lowest common denominator
Answer:
3 and 8
Step-by-step explanation:
3 and 8 because 8 can only divide by 2 or four and get 4 and 2, and 3 can not get to any of these number.
Which is the equation of a line that has a slope of -5 and passes through point (-3,-1)? O y=-3x+1 O y=-3x+3 O y=-x-1 O y=-x-3 3
Note: Your answer choices are not clear, thus I have solved the complete question which anyways should be able to clear your concept.
Answer:
The equation of a line that has a slope of -5 and passes through the point (-3,-1) will be:
y = -5x - 16Step-by-step explanation:
Given
slope = m = -5point = (-3, -1)We know that the slope-intercept form of the line equation is
[tex]y=mx+b[/tex]
Here:
m is the slopeb is the y-interceptNow, substituting m = -5 and (-3, -1) in the slope-intercept form of the line equation to determine the y-intercept 'b'
[tex]y=mx+b[/tex]
-1 = -5(-3) + b
switch sides
-5(-3) + b = -1
15 + b = -1
b = -1 - 15
b = -16
Now, substituting m = -5 and b = -16 in the slope-intercept form of the line equation to determine the equation of a line
[tex]y=mx+b[/tex]
y = -5x + (-16)
y = -5x - 16
Therefore, the equation of a line that has a slope of -5 and passes through the point (-3,-1) will be:
y = -5x - 16Note: Your answer choices are not clear, thus I have solved the complete question which anyways should be able to clear your concept.

can someone help me plz 2a+1=1
Answer:
0
Step-by-step explanation:
2a+1=1
2a=0
--- ---
2 2
a=0
Answer:
A=0
Step-by-step explanation:
2a+1=1
2a=1-1 (i moved +1 to the other side ...coz our goal is to isolate "a", and in order to do this, look for numbers that are freer)(moving the +1 to the other side made it -1)(you just need to remember that when we move any number to the other side it will claim its opposite operation so +1 will turn to -1)
2a=0 (1-1=0)
a=0/2 (now, 2 is being multiplied with a, and to isolate "a" we move 2 to the other side, and this will make to divide ((because the opposite of multiplication is division)) )
a=0 (the ans!)
