Answer:
(a)
Step-by-step explanation:
To determine if the points are a solution to the equation.
Substitute the coordinates of the point into the left side of the equation and if equal to the right side then they are a solution.
(2, 5)
- 3(2) + 4(5) = - 6 + 20 = 14 ← True
(4, 6)
- 3(4) + 4(6) = - 12 + 24 = 12 ← False
Thus (2, 5) is the only solution to the equation → (a)
Answer: 40 questions
Step-by-step explanation:
set it up as an equation
38/x = 95/100
cross multiply
95x=3800
solve for x
x=40
The equation of the line will be y = -3.9, and the height after rounding off will be -4.
<h3>What is a straight line?</h3>
A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
The horizontal line can be defined as:
y = a
Where a is the constant.
Here a = -3.9
y = -3.9
The height = -3.9 ≈ -4
Thus, the equation of the line will be y = -3.9, and the height after rounding off will be -4.

-x + 2y = 6 then x = 2y - 6
6y = x +18 then x = 6y - 18
-----------------------substract
0 = -4y + 12
4y = 12
y = 3
-x + 2y = 6
-x + 2(3) = 6
-x = 6 - 6
x = 0
answer: x = 0 (second choice)
