Answer:

$\boxed { - 4}$

Step-by-step explanation:

Substitute y = x-4 in the first equation.

$3x - 2(x - 4) = 4$

Distribute -2 in the expression.

$3x - 2x + 8 = 4 \\ x = 4 - 8 \\ x = - 4$

Because we only want to find the value of x.

Therefore the answer is -4.

Evaluate the upper and lower sums for f(x) = 2 + sin(x), 0 ≤ x ≤ π, with n = 2, 4, and 8. Illustrate with diagrams like the figu

larisa [96]

$f(x)=x+sin(x)\\ a=0\\ b=\pi \\ x_i=a+idelta(x)\\ Upper sum for n=2:\\ \\ delta(x)=\frac{b-a}{n} =\frac{\pi-0}{2} =\frac{\pi}{2}$

$x_0=0, x_1=\frac{\pi}{2} ,x_1=\pi \\$

Length of the subintervals: $[0,\frac{\pi}{2}], [\frac{\pi}{2}, \pi}]$

Using Upper Riemann sum,

$\int\limits^0_\pi{x+sin(x)\, dx =$ ∑Max{f(x_i) delta(x)

$=[max{(f(x_1))+max(f(x_2))]delta(x)\\ =(3+3)\frac{\pi}{2} \\=9.42$

Lower sum for n=2:

The minimum value for the function on $[0,\frac{\pi}{2}], [\frac{\pi}{2}, \pi]$ is 2.

$\int\limits^0_\pi {x+\sin x} \, dx =\sum_{n=0}^{n=2} min {f(x_i)} delta (x)\\$

$= (2+2)\frac{\pi}{2}\\ =6.28$

The fence around a rectangular horse ranch is 450 m long. If the ranch is 80 m wide, fine its area.

vazorg [7]

The total length of the fence is 450 m

2L + 2W = perimeter

2l + 2w = 450
2l + 160 = 450
2l = 290
l = 145

area = (145)(80)
= 11,600 m^2
