Answer: 1x + 2y = 4
Step-by-step explanation:
The equation of the line is y = -1/2x + 2.
First, let's make 4 on one side of the equation. First, bring x to the left. y + 1/2x = 2. Then multiply the whole equation by two. Thus, 1x + 2y = 4.

Answer:
624
Step-by-step explanation:
The sequence is 49, 47, 45,...., 7, 5, 3. This is an arithmetic sequence, because the difference between terms is the same.
The sum of the first n terms of an arithmetic sequence is:
S = n/2 (a₁ + an)
where a₁ is the first term and an is the nth term.
Here, we know that a₁ = 49 and an = 3. But we need to find what n is. To do that, we use definition of an arithmetic sequence:
an = a₁ + (n-1) d
where d is the common difference (in this case, -2)
3 = 49 + (n-1) (-2)
2(n-1) = 46
n - 1 = 23
n = 24
So there are 24 terms in the sequence.
The sum is:
S = 24/2 (49 + 3)
S = 12 (52)
S = 624
There are 624 bricks in the wall.
Answer:
(-5, 0) and (0,4)
Step-by-step explanation:
Given equation: -4x + 5y = 20
Sub. in the values
When x = -5 and y = 0 (-5,0),
When x = 0 and y = 4 (0,4),
That's how I would do it, not sure if your school has another method. Hope this helps :)
Answer:
The next time she will have both meetings on the same day again is 24 days time
Step-by-step explanation:
The given information are;
The frequency of the Junior Optimist club meeting = Every 3 days
The frequency of the Drama club meeting = Every 8th day
The club meeting Anna will attend today = Both meetings
The next time she will have both meetings on the same day again is given as follows;
The next time she will have both meetings on the same day again = The number of days the complete cycles of both meetings will coincide = The product of the cycles of both meetings
The next time she will have both meetings on the same day again = 8 × 3 = 24 days
The next time she will have both meetings on the same day again = 24 days time.
