Answer:
y = ( x-4)(x+7)
Step-by-step explanation:
When we know the zeros of the equation, we can write the equation in the form
y= a(x-z1) (x-z2) where a is a constant and z1 and z2 are the zeros (solutions)
y = a( x-4)(x--7)
y =a( x-4)(x+7)
Since its says write an equation, we can pick a and I will let a=1
y = ( x-4)(x+7)
Step one: common denominators ex. 25/100, 79/100
step two: add the numerators and keep the denominators the same (addition)
step three: biggest fraction first!! subtract the numerators keep the denominators the same (subtraction)
step four: have a nice time with fractions
Compute the correlation coefficient for the data set. (2,19), (3,22), (4,26), (5,20), (6,35), (7,30), (9,40), (10,42), (11,35) E

Explanation
We are asked to compute the correlation coefficient using a graphing calculator
To do so, we have the following:
From the data plot above, we have the correlation coefficient as:
So the answer is 0.87 (to 2 decimal places)
Answer:
polygon is 15 side
Step-by-step explanation:
Here sum of interior angels is 2340 degrees. Therefore, the polygon is 15 side
35 degrees.
Sum of angles in triangle: 180
35 = 180 - (180-88) - (180-127)
