Answer: 20
Step-by-step explanation:
Hello :
<span>8x²+7x-3+4x-8 = 8x² +(7x+4x) +(- 3 - 8)=8x²+7x - 11</span>
Answer: Both the equations when solved have different answers, the solutions for both the equation are given below. In the the first equation 4 (x-3)=16 , 4 is multiplied with both the terms in the bracket. Whereas, in the second equation 4x- 2 = 16 there is no variable to multiply with the LHS equation
Solution:
4 (x-3)=16
4x - 12 = 16
4x = 16 + 12
4x = 28
x = 7
4x - 3 = 16
4x = 16 + 3
4x = 19
x = 19/4
x = 4.75

Answer:
Extrapolation
Step-by-step explanation:
Given
Explanatory variable
Response variable
Required
Predicting y outside range of x is called
This is referred to as extrapolation.
Take for instance, the range of x is: 1 - 9
You have extrapolated when, 10 is assumed to be the value of x and this value is entered in an equation to predict y.
