Answer:
The answer is either (3) or (4) because drawing a line of best fit and finding its gradient is going to give you a negative answer
7 and 8 because the square root is 7.874
Answer:
$5
Step-by-step explanation:
We want to find the cost of a notepad considering a magazine costs $3 and we buy 2 notepads and the total cost of the magazine and the 2 notepads is $13 so we can set up an equation to represent this situation. Let 'n' be notepads and that's the value we are solving for so,
⇒ Form the equation
→ 2n + 3 = 13
⇒ Minus 3 from both sides to isolate 2n
→ 2n = 10
⇒ Divide both sides by 2 to find the cost of one notepad
→ n = 5
The cost of one notepad is $5 considering that a magazine cost's $3 and two notepads and total is $13.
The given equation is
Consider the slope-intercept form.
Rewriting the given equation in the slope-intercept form.
Subtracting 3x from both sides, we get
Dividing both sides by 5, we get
Compared to the slope-intercept form, we get m=-0.6 and b=1.4.
Hence the slope m= -0.60.
