First, distribute the right side.
8*(x + 5) = 8x + 40
Then, we write the whole equation:
8x + 47 = 8x + 40
Looking at it, we can subtract 8x from both sides, so that we're left with:
47 = 40
However, we obviously know that 47 is NOT equal to 40, so there is <em>no solution</em> for this equation.
Hi there!
The perimeter of any square is the side of the square multiplied by four.
Perimeter= 4 x (5x-2)
Then distribute the four over parentheses.
Perimeter= 4(5x)-4(2)
Perimeter= 20x-8
Hope this helps :)
Answer:
the first one
Step-by-step explanation:
multiply by 4 subtract 2
Answer:
x = -4/7, y = 2/7
Step-by-step explanation:
Given: f(x) = 3x + 2 and g(x) = - 4x - 2
The point of intersection of the two functions is the point at which both functions intersect. We have to solve the functions simultaneously to get the solution.
f(x) = y = 3x + 2
y = 3x + 2 (1)
g(x) = y = -4x - 2
y = -4x - 2 (2)
Subtract equation 2 from equation 1:
0 = 7x + 4
7x = -4
x = -4/7
Put x = (-4/7) in y = 3x + 2:
y = 3(-4/7) + 2 = -12/7 + 2 = 2/7
4y+ 3 is greater than y+ 6
