Answer:
You have a thing on there saying the answer is c. If you got the answer there is no point of asking it.
Answer:
The constant proportionally of the graph is:
Step-by-step explanation:
We know that when 'y' varies directly with 'x', we get the equation
y ∝ x
y = kx
k = y/x
here 'k' is called the constant of proportionality.
From the graph, it is clear that:
at x = 0.5, the value of y = 4
so substituting x = 0.5 and y = 4 in the equation
k = y/x
k = 4/0.5
k = 8
at x = 1, the value of y = 8
so substituting x = 1 and y = 8 in the equation
k = y/x
k = 8/1
k = 8
Therefore, the constant proportionally of the graph is:
Answer:
9+t= 54
Step-by-step explanation:
The amount of money Emma receives in this scenario is £35.
<h3>What is Ratio?</h3>
This is defined as a comparison of numbers that indicates their sizes in relation to each other.
Helen and Emma = 2 : 5
2 = 5
x = x+21
We then cross multiply
5x = 2 ( x+21)
5x = 2x + 42
5x - 2x = 42
3x = 42
x = 42/3 = 14
Emma received x+21
= 14+21 = £35

Answer:
Slope of Function B = 2 x Slope of Function A.
Step-by-step explanation:
The graph of Function B shows its slope to be 4 units up for 1 unit to the right, so 4.
The equation for Function A shows its slope to be the coefficient of x, so 2.
___
4 is 2 times 2, so ...
the slope of Function B is 2 times the slope of Function A.
