Answer:
r = 4
Step-by-step explanation:
If we clearly observe a point and the slope of the line are given.
Point=(5, -6) slope= -5
We know that the equation of the line having slope m and passing through point () is
Now the equation of the line is
Now given that (3,r) lies on this line
r = 4

What is equation of a line?
The general equation of a line in two variables of the first degree is represented as Ax + By +C = 0, A, B ≠ 0 where A, B and C are constants which belong to real numbers.
When we represent the equation geometrically, we always get a straight line.
Given that, an equation of a line y = -3x+9, we need to determine the slope and the y-intercept of this line,
The slope of a line tell about the steepness and the y-intercept tells the point where it intersects the y-axis,
The slope-intercept form of the equation of a line is given by ;
y = mx+c
Here, m is the slope and c is the y-intercept,
So, the given equation is y = -3x+9
Comparing with the slope-intercept form,
m = -3 and y-intercept = 9
Hence, the slope and y-intercept of the given line are -3 and 9 respectively.

Charlie got 24 more sweets than Adrian.
Work out the total amount of sweets.
Answers
Answer:
240 sweets total
Step-by-step explanation:
We know the ratio Adrian:Ben:Charlie=7:4:9. We can put one sweet as x:
- 7x+4x+9x=20x
- Charlie has 24 more sweets that Adrian– 9x-7x=2x=24
- So– x=12
- Now– 7(12)+4(12)+9(12)=20(12)=240
Check your work:
- 84:48:108
- 108-84=24
- 84+48+108=240
Answers
Answer:
A. 25%
25% is equivalent to 1/4 and when you multiply 75 by 4 you get 300. Which means 75 is equivalent to 1/4 and 1/4 is equivalent to 25%. So the answer is 25%. I'm so sorry if this explanation is bad
