Step-by-step explanation:
7x+5y=25 ×3 7×-1.5+5y=25
5x+3y= -23 ×5 -10.5 +5y =25
5y= 25 + 10.5
21x+15y=75 5y= 35.5
25x+15y=69 y= 7.1
-4x=6
x=-1.5
Answer:what ever x equals times 3
Step-by-step explanation:
Answer:
Given expressions are equivalent.
Step-by-step explanation:
Given expression:
4 (x + 3) + 2x and 6 (x + 2)
Find:
Given equivalent expressions or not
Computation:
By taking LHS
4 (x + 3) + 2x
4x + 12 + 2x
6x + 12
By taking RHS
6 (x + 2)
6x + 12
We say that
LHS = RHS
So,
Given expressions are equivalent.
To find the area between the x-axis and the parabolic curve, take the integral of the area in which the curve is above the x-axis.
function of the graph is
y = 4x - x²
We can tell by the function (specifically -x²) that the parabola will point downward.
To find the domain in which y>0, let's find the roots (0's) of the function:
0 = 4x - x²
0 = x (4 - x)
x = 0 or x = 4
Between x=0 and x=4, the curve is above the x-axis. To find the area of the graph, let's take the integral on this range:
First, take the antiderivative of 4x - x²:
2x² - (1/3) x³
Then, plug x=4 into the anti-derivative, and subtract the anti-derivative at x=0:
2(4)² - (1/3)(4³) - (0 - 0)
32 - 64/3
96/3 - 64/3 = 32/3
