43.97
Step-by-step explanation:
just minus both the numbers but dont forget to put the percentage after the 55
Answer:
A
Step-by-step explanation:
y = (-2/5)x + 1
By inspection of the equation, the slope of the line is -2/5 and the y-intercept is 1.
Therefore, we can immediately discount option B and D, as their y-intercepts are NOT 1.
Find the point where the line crosses the x-axis by setting the equation to 0 and solving for x:
0 = (-2/5)x + 1
⇒ -1 = (-2/5)x
⇒ -5 = -2x
⇒ x = 5/2
Therefore, the line of the function intersects the x-axis at x = 5/2 = 2.5
From inspection of the graphs, the line in option A intersects the x-axis at 2.5. Therefore, this is the correct graph.

because ur didviding 14 and too
Answer:
B
Step-by-step explanation:
Given y and x vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 27 when x = 4 , then
27 = 4k ( divide both sides by 4 )
= 6.75 = k
y = 6.75x ← equation of variation
When x = 12 , then
y = 6.75 × 12 = 81
