Answer:
-3, uh its a short answer
Answer:
NO, It’s not a right triangle
Explanation:
Using the converse of Pythagoras’ theorem if the triangle is right then
Square on longest side = sum of square of the other sides
70^2= 4900
55^2 + 42^2 = 4789
Since 4900 ≠ 4789 not a right triangle
Answer:
Solution of the equations is (1, -2).
Step-by-step explanation:
Two linear equations given in the question are
y = -3x+1-------------(1)
and y = 2x-4 ------------(2)
To solve these equations by substitution method we will substitute the value of y from equation (1) to equation number (2).
-3x+1 = 2x-4
Now we add 3x on both the sides of the equation
3x-3x+1 = 3x+2x-4
1 = 5x-4
we will add 4 on both the sides
1+4 = 5x-4+4
5 = 5x
Then we divide the equation by 5
5/5 = 5x/5
x = 5/5 = 1
Now we solve the equation (1) for the value of y by putting x = 1
y = -3(1)+1 = -3+1 = (-2)
So the solution will be (1 -2).
Answer:
It might be B so yeah sorry if it isn't
Answer:
The correct answer is a.
Step-by-step explanation:
This is the so-called double fraction that can be displayed in this way
( y∧2 + y / y∧2-2y) : ( 4y + 4 / y∧2 -4y+4) = (y∧2+y / y∧2-2y) (y∧2-4y+4 / 4y+4)=
Divided with one fraction is the same as multiplying with its reciprocal value
We will draw out common denominators
= ( y(y+1) / y(y-2) ) ( (y-2)∧2 / 4(y+1) ) or ( y(y+1) / y (y-2) ) ( (y-2) (y-2) / 4 (y+1) )
Good luck!!!!
