Answer:
The rule is: y = -10x+85
Step-by-step explanation:
The rule is given by:

Here m is the gradient and b is the y-intercept.
We have to take two pairs of input-output to find the rule
Let the two pairs be:
(x1,y1) = (1,75)
(x2,y2) = (2,65)
Slope is found using the formula:

Putting the values

Putting the value of slope

Putting a pair of input-output in the equation (1,75)

Putting the value of b

Hence,
The rule is: y = -10x+85
10, 2+10=12x5=60 so when you have 2x5, which is 10, +_x5, you need to find a way to make it equal 50, so 10x5
i explained it bad sorry
Answer:
40 cm
Step-by-step explanation:
This is because the angle opposite the x is equal to the angle opposite the 40 cm making the sides equal as well.

v
Step-by-step explanation:
First line them up an take the numbers like this for ex: x + x > x
Then continue to do that with different orders.
Finally, Important: make sure the greater sign has to be like this: > not like this <. If it is = or < it is not a angle. Therefore you can find your answer.
Answer:
45°
Step-by-step explanation:
The angles of any triangle add up to 180 degrees
add the two known angles: 47+88=135
then subtract the sum from 180 to get answer: 180-135=45
