1) 16y - 24x = 8 (2y - 3x)
2) 3x - 6x²y + 12x²= 3x(1 - 2x²y + 4x)
3)2x² - 10x = 2x ( x -5)
4) 15x² - 20x³ = 5x²(3 -4x)
If you explain what they mean by DOTS i might be able to help you from 5-8
hope it helps for 1-4 tho
Answer:
Step-by-step explanation:
Part A: (3,2)
connect all the points on the paper
Part B: 5 units. We know this since the x point for A is -2 and the point for B is 3. -2 to 3(absolute value of -2 plus 3)= 5
Answer:
y = - 0.9167 - 0.75x
Step-by-step explanation:
Given the data:
(−1, 0), (1, −2), (3, −3)
X : - 1, 1, 3
Y : 0, - 2, - 3
The regression model is written in the form:
y = C + mx
Where ;
C = intercept ; m = slope / gradient
Using the regression model calculator on the data values given above :
Slope (m) = - 0.75
Intercept (c) = - 0.9167
Hence,
y = - 0.9167 - 0.75x
c
Answer:
x = 80000/L f
Step-by-step explanation:
When using only three sides for fencing a rectangular area, sides will be
"x " and "y " x = 2*y x is the largest side of the rectangular area
we only fence one y side ( the other side is a river
So the perimeter is L = x + 2*y or L = 4*y
On the other hand if now the area will be 20000 f²
A = x*y = 20000 ⇒ y = 20000/ x
As the fence material is the same as that of the maximum area
L = 4*y L = 4* 20000 / x
L*x = 80000
Then x = 80000/L
Where L is the quantity of fencing material
