Answer:
Laila gets £470
Step-by-step explanation:
Let John's share=x
Laila's share=x+80
The sum of their individual shares should equal 860
therefore x+x+80=860
2x=860-80
2x=780
x=390
Therefore each person's share:
John-£390,Laila-£470
Answer:
(- 2, 15 ) and (2, 7 )
Step-by-step explanation:
Given the 2 equations
y = 3x² - 2x - 1 → (1)
2x + y = 11 → (2) ← subtract 2x from both sides
y = 11 - 2x → (3)
Substitute y = 3x² - 2x - 1 into (3)
3x² - 2x - 1 = 11 - 2x ( subtract 11 - 2x from both sides )
3x² - 12 = 0 ( add 12 to both sides )
3x² = 12 ( divide both sides by 3 )
x² = 4 ( take the square root of both sides )
x = ±
= ± 2
Substitute these values into (3) for corresponding values of y
x = - 2 : y = 11 - 2(- 2) = 11 + 4 = 15 ⇒ (- 2, 15 )
x = 2 : y = 11 - 2(2) = 11 - 4 = 7 ⇒ (2, 7 )
Answer:
The answer is
![\huge y = 4x - 2](https://tex.z-dn.net/?f=%20%5Chuge%20y%20%3D%204x%20-%202)
Step-by-step explanation:
To find an equation of a line given the slope and a point we use the formula
![y - y_1 = m(x - x_1)](https://tex.z-dn.net/?f=y%20-%20%20y_1%20%3D%20m%28x%20-%20%20x_1%29)
From the question the point is (-1,-6) and slope 4
The equation of the line is
![y + 6 = 4(x + 1) \\ y + 6 = 4x + 4 \\ y = 4x + 4 - 6](https://tex.z-dn.net/?f=y%20%2B%206%20%3D%204%28x%20%2B%201%29%20%5C%5C%20y%20%2B%206%20%3D%204x%20%2B%204%20%5C%5C%20y%20%3D%204x%20%2B%204%20-%206)
We have the final answer as
![y = 4x - 2](https://tex.z-dn.net/?f=y%20%3D%204x%20-%202)
