Week = w
1 hour = d

Formula

w = dm + c

The m is the gradient

The c is the d when w is 0

First let’s do m
m is basically how much the d changes from one point to another

So how much does d changes from 20 to 15.5

Which figure does not always have congruent diagonals?
fomenos
If you cut a diagonal line across a square, both sides look equal. A rhombus also looks equal and so does a rectangle. However when you look at trapezoid, it has shorter top and a larger bottom. Cut that in half diagonally and you can see that one half would be smaller than the other.

raffle tickets are being sold for a fundraiser. The relationship between n, number of raffle tickets sold, and A, amount of mone
jolli1 [7]

Answer:

D. N(a) = (a + 20)/3

Step-by-step explanation:

A(n) = 3n - 20

A is a function of n. The inverse will be: N is a function of a.

Change A(n) to y and n to x.

y = 3x - 20

Switch x and y.

x = 3y - 20

Solve for y.

x + 20 = 3y

3y = x + 20

y = (x + 20)/3

Now switch y to N(a) and x to a.

Answer: N(a) = (a + 20)/3

find the equation of the line that passes through P(7,20) and Q the midpoint of R (-3,5) and S (5,11)
sergejj [24]
First we have to find midpoint of R and S.
We can use formula such for it.Qx= \frac{Rx+Sx}{2} and Qy= \frac{Ry+Sy}{2}.
We obtained coordinates of point Q 
Qx= \frac{-3+5}{2}=1 and Qy= \frac{5+11}{2}=8

Now, we can find the line equation using formula y=ax+b. 
We can substitute coordinates of P and Q to this formula and solving system of equation get the answer.

After substituting we obtaind such system
\left \{ {{20=7a+b } \atop {8=a+b}} \right.

From the system of equation we obtain result
\left \{ {{a=2} \atop {b=6}} \right. 

Now we can put our resuts to general line equation.
y=2x+6
