Show the inequality for x. Show each step of the solution 12x>7(4x+5)-19

Mathematics
1 answer:
Dima020 [189]3 years ago
3 0

Answer:

x<-1

Step-by-step explanation:

12x>7(4x+5)-19

<u><em>Solve the right side</em></u>

12x > 28x+35-19

12x > 28x+16

<u><em>Make x the subject</em></u>

12x-28x > 16

-16x > 16

-x > 16/16

-x > 1

Multiplying by -1 on both sides

x < -1  

If you multiply ">" with minus sign, its direction changes. It is similar to switching the positions of x and -1.  

<u><em>Simplify</em></u>

x < -1

The inequality of x is x<-1

Solve the differential equation dy dx equals the quotient of x squared and y squared for y = f(x) with the initial condition y(0
Gnoma [55]
\displaystyle\frac{dy}{dx} = \frac{x^2}{y^2}\ \Rightarrow\ y^2 dy = x^2 dx\ \Rightarrow\ \int y^2 dy = \int x^2 dx\ \Rightarrow\textstyle\ \frac{1}{3}y^3 = \frac{1}{3}x^3 + C. \\ \\&#10;\text{Now } y(0) = 2\ \Rightarrow\ \frac{1}{3}(2)^3 = \frac{1}{3}(0)^3 + C\ \Rightarrow\ \frac{8}{3} = C,\text{ so } \frac{1}{3}y^3 = \frac{1}{3}x^3 + \frac{8}{3}. \\ \\&#10;y^3 = x^3 + 8\ \Rightarrow\ y = \sqrt[3]{x^3 + 8}

Write the equation of the line in slope-intercept form that goes through the points: (2,4) and (7,-1)
IgorC [24]

Answer:

y= -x+8

Step-by-step explanation:

slope int. form: y=mx+b

first, we need to find the slope (m)

the two points are (2,4) and (7,-1).

to find the slope we do (y2-y1)/(x2-x1)

doing this we get -5/5=-1

now we can plug in point (2,4) and the slope into y=mx+b

doing this we get:

4=-1(2)+b

4=-2+b

b=8

now we have the equation:

y= -x+8

If the circle below is cut from the square of plywood below, how many square inches of plywood would be left over? Use π = 3.14,
Elis [28]

Answer:

86in²

Step-by-step explanation:

Find the complete question attached

Area of the circle = πr²

Area of the square = L²

Length of the side of the square

r is the radius of the circle

r = L/2 = 20/2 =10in

Given

Length of the side of the circle = 20in

Area of the square = 20²

Area of the square = 400in²

Area of the circle =π(10)²

Area of the circle = 3.14(100)

Area of the circle= 314in²

Amount of plywood left over = 400in²-314in² = 86in²
