Determine the pattern rule for the table and write it as an equation.​

Answer:

The rule is: y = -10x+85

Step-by-step explanation:

The rule is given by:

y = mx+b

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:

m = \frac{y_2-y_1}{x_2-x_1}

Putting the values

m = \frac{65-75}{2-1}\\m = -10

Putting the value of slope

y = -10x+b

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

75 = -10(1) +b\\75 = -10+b\\b = 75+10\\b = 85

Putting the value of b

y = -10x+85

Hence,

The rule is: y = -10x+85

Answer:

Read below |

                    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.

A scalene triangle has an angle that measures 47∘ and a second angle that measures 88∘. What is the measure of the third angle?
umka21 [38]

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
