There you go hope you are satisfied with my answer
-2(x + 5) - (4x + 10)
(-2x + -10) - (4x + 10)
(-2x + -10) -4x -10
-2x + -10 -4x -10
-6x = 0
x =0
Answer:
A(3,-1) and B( -2,1)
Step-by-step explanation:
2x+5y=1. , or. y=(1–2x)/5………….(1)
x^2+5xy-4y^2+10=0…………………..(2)
Putting y=(1–2x)/5 from eqn. (1)
x^2+5x.(1–2x)/5–4/25.(1–2x)^2 +10=0
or. 25x^2+25x.(1–2x)-4.(1+4x^2–4x)+250 = 0
or. 25x^2+25x-50x^2–4–16x^2+16x+250=0
or. 41x^2–41x-246=0
or x^2– x - 6=0
or. (x-3).(x+2)=0
=> x= 3 or -2
But y=(1–2x)/5
=> y= (1–6)/5 or. (1+4)/5
hence, y= -1. or. 1
Answer:
Option B
Step-by-step explanation:
Given are three tables in x and y and we have to find which table shows a linear relation.
We know in a linear relation between x and y the graph would be a straight line and also the slope would be constant
i.e. change of y/change of x for any pair in the table would be a constant.
Out of three tables given, only second table satisfies this.
Hence B is the answer
Lets look at it as the Pythagorean theorem, so A²+B²=C²
First step: find the X (a) and the Y (b)
|6-0| = 6
|-4-2|= 6
Second step: 6²+6²=c²
36+36=C²
72=C²
√72=√C²
8.49=C
your final answer would be 8.49 units
