Answer:
Step-by-step explanation:
From the coordinate geometry, equation of line that passes through two coordinates will be
y-y1 ={(y2-y1)/x2-x1)}(x-x2) where x1=3,y1= -2, x2 =6, y2 = 3. therefore substitute for the values
y-(-2) ={ 3-(-2)/6-3} x (x-6)
y+2 = 3+2/3 x (x-6)
y+2 =5/3(x-6) multiply both side by 3,
3(y+2) = 5(x-6)
3y+6 =5x-30
3y = 5x -30 -6
3y = 5x - 36. Therefore the equation of the line is
3y = 5x - 36.
Answer: 36 three-point field goals.
Step-by-step explanation:
To solve this problem, set up a system of equations. Let's call the number of one-pointers 
, the number of two-pointers 
, and the number of three-pointers 
. We are trying to find here. We also know that 
, because that is the total amount of baskets, and also that 
, which is the total amount of points. We know that there were 22 free throws, so that means we can take away 22 baskets from the first equation, and also 22 points from the second equation. Now the equations are 
and 
. Solving the equations using our knowledge of systems of equations, you get that 
. So, 36 is the answer. Let me know if anything was unclear, and I hope this helped.
20%
A change from 65 to 78 represents a positive change (increase) of 20%
Use the formula found below to find the percent change by replacing the given values:
Percent change = [(New - Old ) / |Old|] x 100%
Answer:
- <em>To solve these first swap x and y, solve for y and name it inverse function</em>
3. <u>y = -8x + 2</u>
- x = -8y + 2
- 8y = -x + 2
- y = -x/8 + 2/8
- y = -(18)x + 1/4
f⁻¹(x) = -(18)x + 1/4
-----------------------------------------
4.<u> y = (2/3)x - 5</u>
- x = (2/3)y - 5
- (2/3)y = x + 5
- y = (3/2)x + (3/2)5
- y = 1.5x + 7.5
f⁻¹(x) = 1.5x + 7.5
-----------------------------------------
5. <u>f(x) = 2x² - 6</u>
- x = 2y² - 6
- 2y² = x + 6
- y² = 1/2x + 3
- y =
f⁻¹(x) =
-----------------------------------------
6. <u>y = (x - 3)²</u>
- x = (y - 3)²
= y - 3- y = 3 +
f⁻¹(x) = 3 +
