The x-intercept = (7, 0)
The y-intercept = (0, -3.5)
Explanation:The given equation is:
-2x + 4y = -14
Find the x-intercept by setting y = 0
-2x + 4(0) = -14
-2x + 0 = -14
-2x = -14
x = -14/-2
x = 7
Therefore, the x-intercept = (7, 0)
Find the y-intercept by setting x = 0
-2(0) + 4y = -14
0 + 4y = -14
4y = -14
y = -14/4
y = -3.5
Therefore, the y-intercept = (0, -3.5)
Considering the x and y-intercepts, the graph is plotted

There are 245 bottles to fill the milk.
What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
A farmer gets 24.5 L of milk from each of his cows per day.
And, He milks all five cows and pours the milk equally into 0.5-L bottles.
Now,
Since, A farmer gets 24.5 L of milk from each of his cows per day.
And, He milks all five cows.
So, The total amount of milk = 24.5 x 5 L
= 122.5 L
Since, He pours the milk equally into 0.5-L bottles.
So, The number of bottles = 122.5 L ÷ 0.5 L
= 245
Thus, There are 245 bottles to fill the milk.

Solve for y: y + 10 = -15
Answers
According to the given data we have the following equation:
y + 10 = -15
To solve the variable y of the equation above we would make the following:
y + 10 = -15
We would move the number 10 to the other side, so it would change its sign.
y=-15-10
Finally add the numbers So:
y=-25
The result of the y would be -25
y + 10=-15
y=-15-10
y=-25

Factor the numbers in a sequence that will have you using 21 numbers.
Answers
The sequence of numbers uses 21 numbers whereas each number in the sequence must be a factor or multiple of the previous number is 1, 7, 21.
We are given numbers from 1 to 24.
We need to find the longest sequence using the number 21 such that each number in the sequence must be a factor or multiple of the previous number.
Let the last number be 21.
The previous number of 21 must be a factor or multiple of 21.
From the given numbers we can only choose 7 as it is a factor of 21.
So, the sequence will be ...., 7, 21.
Now,
The previous number of 7 must be a factor or multiple of 7.
From the given numbers we can only choose 1 as it is a factor of 7.
So, the sequence will be 1, 7, 21.
There is not any previous number to 1.
So, our final sequence will be 1, 7, 21.
Thus, the sequence of numbers uses 21 numbers whereas each number in the sequence must be a factor or multiple of the previous number is 1, 7, 21.

48% in simple fraction
Answers
To transform a percentage to a simple fraction we divide the number by a 100, then we have:
[tex]\frac{48}{100}=\frac{12}{25}[/tex]Therefore 48% in simple fraction is equal to 12/25
First we start to convert 48% to a fraction.
48% = 48/100
Now we find the (GCF) or the greatest common factor of 48 and 100.
4 is the greatest common factor.
We divide the numbers by the greatest common factor to simplify the fraction to its’ simplest form.

The equation for a straight line can be found if its slope and coordinate of the point it passes through is given. The equation for the given graph is c = 60w. The correct answer is option C.
What is the equation for a straight line?A straight line can be written in the form of equation as, y = mx + c.
Two straight lines intersect each other only at one point.
When two straight lines are parallel to each other the angle between them is zero.
Given that,
The cost of food delivery is taken as c.
The number of weeks is w.
Since the graph given in the problem is a straight line, in order to find its equation its slope has to be found as follows,
From the graph, it is clear that at w = 2, c = 120.
Now, there are two points for the given straight line as (0, 0) and (2, 120).
Thus, the slope is given by (120 - 0) / (2 - 0) = 60
Then the equation for the straight line is,
(c - 0) / (w - 0) = 60
=> c = 60w
Hence, the equation of the given graph is c = 60w.

Answers
50% means 50/100 = 0.5
300% means 300/100 = 3
Now,
A number, let it be "100" (you can take any number, the answer would be the same).
It is decreased by 50%, so
100 - (0.5)(100) = 50
Then, it is increased by 300%, so
50 + 3(50) = 200
So, we started off with 100 and now we're at 200.

So, original was 100 and final is 200, essentially:
100 is what percent of 200??
100/200 = 0.5
