Answer:x=1

Step-by-step explanation:(4x+-7)=(2x+-9)

We move all terms to the left:

(4x+-7)-((2x+-9))=0

We add all the numbers together, and all the variables

(4x-7)-((2x-9))=0

We get rid of parentheses

4x-((2x-9))-7=0

We calculate terms in parentheses: -((2x-9)), so:

(2x-9)

We get rid of parentheses

2x-9

Back to the equation:

-(2x-9)

We get rid of parentheses

4x-2x+9-7=0

We add all the numbers together, and all the variables

2x+2=0

We move all terms containing x to the left, all other terms to the right

2x=-2

x=-2/2

x=-1

(4x+-7)=(2x+-9)

We move all terms to the left:

(4x+-7)-((2x+-9))=0

We add all the numbers together, and all the variables

(4x-7)-((2x-9))=0

We get rid of parentheses

4x-((2x-9))-7=0

We calculate terms in parentheses: -((2x-9)), so:

What is the product? (x 3)(2 x minus 1) 2 x squared minus 3 2 x squared 6 x 2 x squared 5 x minus 3 2 x squared 6 x minus 3.

prohojiy [21]

The product of the function is 2x^2+ 5x - 3

We are to find the product of the functions x + 3 and 2x -1

let f(x) = x+ 3

g(x) = 2x - 1

Taking the product:

f(x)g(x) = (x+3)(2x -1)

f(x)g(x) = x(2x) - x(1) + 3(2x) + 3(-1)

f(x)g(x) = 2x^2 - x + 6x - 3

f(x)g(x) = 2x^2+ 5x - 3

Hence the product of the function is 2x^2+ 5x - 3

Solve the differential equation. question is pictured with answer choices

Nimfa-mama [501]

Integrate both sides with respect to t :

∫ dy/dt dt = ∫ -12t ² dt

y(t) = -4t ³ + C

Use the initial condition to solve for C :

5 = -4•0³+ C

C = 5

y(t) = -4t ³ + 5

and the answer is D.

Alternatively, you can directly apply the fundamental theorem of calculus:

$\dfrac{\mathrm dy}{\mathrm dt}=-12t^2\implies y(t)=y(0)+\displaystyle\int_0^t -12u^2\,\mathrm du$

$\implies y(t)=5-4u^3\bigg|_0^t$

$\implies y(t)=5-4t^3$
