Answer:

Step-by-step explanation:

2x+3+4 side

add similar variables (3 + 4=7)

then you get 2x+7 = 7+5x

move 2x to opposite side to issolate x variable

subtract 2x by 5x = 3x

then you get 7=7+3x

then move 7 to opposite side to isolate

then you get 0=3x

you then divide 3x by 0

anything divided by 0 is 0 making the final answer

Answer:

x = 0.

Step-by-step explanation:

2x + 3 + 4 = 7 + 5x

We need to bring all the x terms to one side ( left) and all the numbers to the right side.

First simplify the left side:

2x + 7 = 7 + 5x

Subtract 5x from both sides

2x - 5x + 7 = 7 + 5x - 5x

-3x + 7 = 7

Subtract 7 from both sides:

-3x + 7 - 7 = 7 - 7

-3x = 0

x = 0/-3 = 0.

Answer:

1. 3

2. -2

3. (1, 2)

Step-by-step explanation:

y axis is the numbered line that looks like the |

x axis is _

so the y int is 3 because A intercepts the y axis at 3

the y int for B is -2 because it intercepts the y axis at -2

the intersection of both lines is (1, 2) because you look and the point is at 1 for x and 2 for y

Use part 1 of the fundamental theorem of calculus to find the derivative of the function. y = cos x (3 + v5)8 dv sin x

dexar [7]

It looks like

$y(x)=\displaystyle\int_{\cos x}^{\sin x}(3+v^5)^8\,\mathrm dv$

(If the limits are in the wrong order, just multiply the result by -1)

Split the integral at an arbitrary value between $\cos x$ and $\sin x$ , and write $y(x)$ as

$y(x)=\displaystyle\left\{\int_{\cos x}^c+\int_c^{\sin x}\right\}(3+v^5)^8\,\mathrm dv$

$y(x)=\displaystyle\int_c^{\sin x}(3+v^5)^8\,\mathrm dv-\int_c^{\cos x}(3+v^5)^8\,\mathrm dv$

Then by the FTC,

$\dfrac{\mathrm dy}{\mathrm dx}=(3+\sin^5x)^8\cdot\dfrac{\mathrm d\sin x}{\mathrm dx}-(3+\cos^5x)^8\cdot\dfrac{\mathrm d\cos x}{\mathrm dx}$

$\dfrac{\mathrm dy}{\mathrm dx}=\cos x(3+\sin^5x)^8+\sin x(3+\cos^5x)^8$
