Answer:
There are 9 highlighters and 8 gel pens
Step-by-step explanation:
The value of y is 56 when x = 8.
Given
y = 343 when x = 49
Value of y varies directly with x
Therefore, y ∝ x
We can write the equation with a constant 'k'
y = kx
When y = 343 and x = 49
343 = k × 49
k = 343/49
k = 7
When x = 8,
y = kx
y = 7 × 8
y = 56
The value of y is 56 when x = 8.

Step-by-step explanation:
An equation is formed of two equal expressions. The solution to the equations is (-4,0) and (4,0).
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The solution of the two of the given equation is the points at which the two equations intersect. Therefore, the solution to the equations is (-4,0) and (4,0).
