Answer:
i would say the answer is true but I'm not completely sure this is the answer.
Answer:
TRUE
Step-by-step explanation:
Find the first four terms of the sequence given by the following.
aₙ=43-3(n-1) n=1,2,3. . .
Given :-
The general term of a sequence is given by aₙ=43-3(n-1) .To Find :-
The first four terms of the sequence.Solution :-
The given expression is [tex] /[/tex]
→ aₙ=43-3(n-1)
where n > 0
Finding the first term :
Substituting n = 1 , we have ,
→ T1 = 43 - 3(1-1)
→ T1 = 43 - 3*0
→ T1 = 43 - 0 = 43
Finding the second term :
Substituting n = 2 , we have,
→ T2 = 43 -3(2-1)
→ T2 = 43 -3*1
→ T2 = 43 -3 = 40
Finding the third term :
Substituting n = 3 , we have,
→ T3 = 43 -3(3-1)
→ T3 = 43 -3*2
→ T3 = 43 -6 = 37
Finding the fourth term :
→ T4 = 43 -3(4-1)
→ T4 = 43 -3*3
→ T4 = 43-9 = 34
Hence the first four terms of the sequence are 43 , 40 , 37 and 34 .

7(-4x - 1) = 49
Not sure of steps
Answer:
Step-by-step explanation:
7(-4x - 1) = 49
-28x - 7 =49
-28x = 49 + 7 = 56
x = 56/(-28) = -2
Answer:
7 x - 4x = - 28x
7 x - 1 = - 7
-28x - 7 = 49
+7 both sides
-28x = 56
÷ - 28
x = 56/-28
x = - 2
I substitute to double check my answer:
- 4x
-4x-2 =8
7(8- 1)
7x 8 = 56
7 x - 1 = - 7
56-7= 49

Answer:
5. (x,y) = (2.3)
Step-by-step explanation:

x = 2
y = 2+1
y = 3
(x,y) + (2,3)
{3 = 1/2 x 2 + 2
{3 = 2 + 1
{3 = 3
{3 = 3
Answer:
3. no solution
5. (x, y) = (2, 3)
Step-by-step explanation:
3.-5x +y = 1
-10x +2y = -2
Multiply the first equation by -2 and add the second equation:
-2(-5x +y) +(-10x +2y) = -2(1) +(-2)
10x -2y -10x +2y = -2 -2 . . . . eliminate parentheses
0 = -4 . . . . . . . . . no variable values will make this true: NO SOLUTION
(The lines graph as parallel lines.)
__
5.y = 1/2x +2
y = x +1
Subtract the first equation from the second:
(y) -(y) = (x +1) -(1/2x +2)
0 = 1/2x -1
0 = x -2
2 = x
y = x +1 = 2 +1 = 3 . . . . use the second equation to find y
The solution is (x, y) = (2, 3).

differentiate between factors and prime factors use relavant examples in your explanations?
Answer:
The factors of a number are all of the numbers that will divide into that number with no remainder. The prime factors of a number are the prime numbers that must be multiplied together to give the number. For example: The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The prime factors of 30 are 2, 3, and 5.
Over the last three evenings, Ann received a total of 70 phone calls at the call center. The first evening, she received 6 more calls than the third evening. The second evening, she received 2 times as many calls as the third evening. How many phone calls did she receive each evening? Number of phone calls the first evening: Number of phone calls the second evening: Number of phone calls the third evening:
Let x represent the number of calls received on the second evening.
The number of calls received on the first evening is x - 10.
The number of calls received on the third evening is 2x.
The sum of calls received on the three evenings is (x - 10) + x + 2x, and this is equal to 50:
(x - 10) + x + 2x = 50
4x - 10 = 50
4x = 50 + 10
4x = 60
x = 60/4
x = 15
The number of calls received on each evening is then:
First evening: x - 10 = 15 - 10 = 5
Second evening: x = 15
Third evening: 2x = 2(15) = 30
Check: 5 + 15 + 30 = 60

Slope = -5/8
Step-by-step explanation:
Take 2 points from the graph where the line is. Point 1: (1 , 6). Point 2: (9 , 1).
We are going to use the formula for finding the slope of a line now.
y2 - y1/x2 - x1 = 1 - 6/9 - 1 = -5/8
Slope = -5/8

Graph the following equation y+2=3/5(x+3)
Answer:
Step-by-step explanation:
It is given
2x−3y=5
we can write it as
3y=2x−5
So we get
y=32x−5
Substituting x=4 in the given equation
y=32(4)−5
So we get
Y=38−5
y=33
By division we get
y=1
Substituting x=−2 in the given equation
y=32(−2)−5
So we get
y=3−4−5
y=3−9
By division we get
y=−3
x 4 -2
y 1 -3
Now draw a graph using the points (4,1) and (−2,3)
Join the point through a line and find the value of y
(i) Based on the graph
consider x=4 on X-axis
Now the line joining the two points and a point on the Y-axis gives the value of y
Therefore,when x=4 the value of y=1
(ii) Based on the graph,
Consider y=3 on Y-axis
Now the line joining the two points and a point on the X-axis the value of x
Therefore, when y=3 the value of x=7
