To graph the equations (sorry i dont have a camera), use the up/down line and on the 6 put a dot, then move one space to the right, and four squares down to place your next dot. This is for y = -4x+6. To graph y = 4x - 2, go back to the up/down line, to the -2 part, and put a dot. then go to the right once, and up four times to place your next dot. when the lines connect, you should be able to find your point, at (1, 2)
£560 is divided between Kate, Nima & Roshana so that Kate gets twice as much as Nima, and Nima gets three times as much as Roshana. How much does Nima get?
Answers
Answer:
£168
Step-by-step explanation:
Amount to be shared = 560
Roshana's share = x
Nima's share = 3x
Kate's share = 2 * 3x = 6x
X + 3x + 6x = 560
10x = 560
x = 560 / 10
x = 56
Nima's share = 3x
Nima's share = 3* 56 = £168
Question 1
Rationalise the denominator.
9
√7-2
Answers
Answer:
[tex]\displaystyle \frac{9}{\sqrt{7}-2}=3\sqrt{7}+6[/tex]
Step-by-step explanation:
Rationalizing the Denominator
Rationalizing the denominator means to get rid of any radicals in the denominator.
We use the conjugate of the denominator to rationalize. The conjugate of a binomial is obtained by changing the sign that is between the two terms while keeping the same order of the terms. For example, the conjugate of
[tex]\sqrt{7}-2[/tex] is [tex]\sqrt{7}+2[/tex].
We need to use the algebraic identity:
[tex](a-b)(a+b)=a^2-b^2[/tex]
Let's rationalize
[tex]\displaystyle \frac{9}{\sqrt{7}-2}[/tex]
Multiply numerator and denominator by the conjugate of the denominator:
[tex]\displaystyle \frac{9}{\sqrt{7}-2}=\frac{9}{\sqrt{7}-2}\cdot\frac{\sqrt{7}+2}{\sqrt{7}+2}[/tex]
Operate in the numerator and apply the identity in the denominator
[tex]\displaystyle \frac{9}{\sqrt{7}-2}=\frac{9(\sqrt{7}+2)}{(\sqrt{7}-2)(\sqrt{7}+2)}[/tex]
[tex]\displaystyle \frac{9}{\sqrt{7}-2}=\frac{9\sqrt{7}+18}{(\sqrt{7})^2-2^2}[/tex]
[tex]\displaystyle \frac{9}{\sqrt{7}-2}=\frac{9\sqrt{7}+18}{7-4}=\frac{9\sqrt{7}+18}{3}[/tex]
Dividing:
[tex]\boxed{\displaystyle \frac{9}{\sqrt{7}-2}=3\sqrt{7}+6}[/tex]

Answers
Answer:
x = 2 and y = 1
Step-by-step explanation:
Given equations are :
2x-y=3 ...(1)
3x+y=7 ...(2)
Add equation (1) and (2) as follows :
2x-y + 3x+y = 3 + 7
2x + 3x = 10
5x = 10
x = 2
Put the value of x in equation (1)
2(2)-y=3
4-y = 3
y = 4-3
y = 1
Hence, the solution of the given equations are (2,1).
