Answer: The correct option is

(B) 1 solution.

Step-by-step explanation: We are given to find the number of solutions that the following equation has :

$2x+3=4x+2~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

To find the number of solutions, we must try to solve the given equation first.

The solution of equation (i) is as follows :

$2x+3=4x+2\\\\\Rightarrow 4x-2x=3-2\\\\\Rightarrow 2x=1\\\\\Rightarrow x=\dfrac{1}{2}.$

Since we can find only one value of x from the equation, so there will be only one solution.

Option (B) is CORRECT.

Answer:

x = 1/2

Step-by-step explanation:

2x + 3 = 4x + 2

-2x -2x

3 = 2x + 2

-2 -2

1 = 2x

Divide both sides by 2x

x = 1/2

Answer:

42+x+90+8=180° linear pair

x=180-140=40°

x=40°

10+x+90+3x=180 linear pair

4x=180-100

x=80/4=20

x=20°

Evaluate the integral by making an appropriate change of variables.

VARVARA [1.3K]

By inspecting the integrand, the "obvious" choice for substitution would be

u = y + x

v = y - x

Solving for x and y, we would have

x = (u - v)/2

y = (u + v)/2

in which case the Jacobian and its determinant are

$J=\begin{bmatrix}x_u&x_v\\y_u&y_v\end{bmatrix}=\dfrac12\begin{bmatrix}1&-1\\1&1\end{bmatrix}\implies|\det J|=\left|\dfrac12\right|=\dfrac12$

The trapezoid R has two of its edges on the lines x + y = 8 and x + y = 9, so right away, we have 8 ≤ u ≤ 9.

Then for v, we observe that when x = 0 (the lowest edge of R), v = y ; similarly, when y = 0 (the leftmost edge of R), v = -x. So

-x ≤ v ≤ y

-(u - v)/2 ≤ v ≤ (u + v)/2

-u + v ≤ 2v ≤ u + v

-u ≤ v ≤ u

So, the integral becomes

$\displaystyle\iint_R5\cos\left(7\frac{y-x}{y+x}\right)\,\mathrm dA=\int_8^9\int_{-u}^u\frac52\cos\left(\frac{7v}u\right)\,\mathrm dv\,\mathrm du$

$=\displaystyle\frac52\int_8^9\frac u7(\sin7-\sin(-7))\,\mathrm du$

$=\displaystyle\frac57\sin7\int_8^9u\,\mathrm du$

$=\displaystyle\frac5{14}\sin7(9^2-8^2)=\boxed{\frac{85}{14}\sin7}$
