Answer:
you did it wrong you have to subtract X from 8900.
First you want to subtract 390 from 8900 and that equals
<h2>8510</h2>
Finish your statement... I'm anxious to help!
Use the point slope formula. then, substitute the values inside the formula.
x1 =3
y1= -2
m = 23
y -y1 = m ( x - x1)
y - (-2) = 23 (x - 3)
y + 2 = 23 ( x - 3)
The average of a set of data is equal to the sum of the values divided by the number of data present. So, if we have three numbers, the average would be:
let x, y and z represent the three numbers
average = x + y + z / 3 = 45
Two number are equal in value, so let x = y. Substituting the value to the expression of average,
45 = x + x + z / 3
45 = 2x + z / 3
It said that the last number is 89 so z is equal to 89.
45 = 2x + 89 / 3
135 = 2x + 89
46 = 2x
x = 23
Therefore, the two numbers are both 23.
Answer:
y=2x+13
Step-by-step explanation:
find gradient which is -2
-7-3/0--5=-10/5 =-2
y-3 =-2. (cross multiply)
x--5
y-3=2x+10
y=2x+13
