X^2 -2x = 0
Get the coefficient of x
divide it by 2
square it
add it to both sides
-2 / 2 = -1
-1^2 = 1
x^2 -2x +1= 1
Take the square root of both sides
(x-1) = sq root (1)
Answer:
x =-11
Step-by-step explanation:
5 +x -2 = -8
3 +x = - 8
x = -3 - 8
x= -11
(1.90 + 7.99+ 4.33 + 5.21) ÷ 4
answer = 4.8575
So hmmm notice the picture below
get the area of the "square" that contains both triangles
and then subtract the area of that gray triangle
notice the base of the triangle, is just 14, the height is 14
the difference, is the area other two blue smaller triangles
Answer:
X = 0 4 8 12
Y = 10 7 4 1
Step-by-step explanation:
Given:
Cost of one T shirt = $15
Cost of one sweater = $ 20
To find :
The graph that will represent both number of T-shirts and sweatshirts = ?
Solution:
Let the number of t-shirts be x
The number of sweaters be y
They want to rise a found of $200
Then the equation to represent this situation is
15x + 20y = 200
By trial and error method
15(12) + 20(1) = 200
15(8) + 20(4) = 200
15(0) + 20(10) = 200
15(4) + 20(7) = 200
