Pls someone answer pls

The solution set of the given inequality is  {b| b > 20}.

Here we have the inequality (3/4)b > 15 and we want to solve it. To do so, we just need to isolate the variable b.

And to do it, we can work with this like we would do with any equation, we can just multipy both sides by (4/3) so we get:

(4/3)*(3/4)*b > 15*(4/3)

b > 20

Then the solution set can be written as {b| b > 20}

That is the set of all values larger than 20.

Answer:

x+1 SQUARE units

Step-by-step explanation:

Area of a rectangle is height times width or you could just say the length on one side times the length of a side right next to it.

If the rectangle is x+1 units long and 1 unit high, then the answer is (x+1)  x 1  = x +1 because anything times 1 is always just what you started with.

Answer:

121

Step-by-step explanation:

If you add them all up, 87+105+135+92= 419

the pentagon is equal to 540 degrees so minus 540 by 419

then you get 121

Step-by-step explanation:

This is well within the mass uncertainty of 0.01% (6×1020 kg), so the estimated value of Earth's mass is unaffected by this factor. Mass loss is due to atmospheric escape of gases. About 95,000 tons of hydrogen per year (3 kg/s) and 1,600 tons of helium per year are lost through atmospheric escape.

Answer:

x= 2

Step-by-step explanation:

7x = 13x -12

0= 13x-12-7x

12= 13x-7x

12= 6x

2= x

you need to bring all the X's to one side then solve from there

Answer:

x=2

Step-by-step explanation:

7x=13x-12

Subtract 13x from both sides

7x-13x=13x-12-13

-6x=12

Divide both sides by -6

-6x/-6=-12/-6

Answer:

y = 2/3x + 4

Step-by-step explanation:

Slope-intercept form of a line:

To find the equation of a line, we need two points that the line passes through.  

We can use the x-intercept and y-intercept of the line: (-6,0) and (0,4), respectively.

Find the slope of the line using these two points:

Plug the two points into the formula.

Subtract and simplify this fraction.

The slope of this line is m = 2/3.

Now we can look at the graph to determine the y-intercept of this line; the line intersects the y-axis at (0,4) so the constant b = 4.

We can use the slope, m, and the y-intercept, b, and substitute these values into the slope-intercept form of a line.

The equation of the line is y = 2/3x + 4.

Answer:

y = 2/3x + 4

Answer:

sine D = 0.9459

sine E = 0.3243

Step-by-step explanation:

Mathematically, sine is the ratio of the opposite to the hypotenuse

The hypotenuse is the longest side and we have it as 37 in the diagram given

the opposite to angle E is 12

So the sine of E = 12/37 = 0.3243

For D , its opposite is 35

The sine of D = 35/37

sine of D = 0.9459

Answer:

25 (with assumptions)

Step-by-step explanation:

ASSUMING ES=SD and FT=TG, then the difference between EF and ST is the same as the difference between ST and DG.  Since ST - EF = 19 - 13 = 6, then DG - ST = 6 or DG - 19 = 6, add 19 to both sides and DG = 25

The x = 3 the quadratic equation D) y = 2x² -3x +7 will have maximum value.

The maximum and minimum values of a function:

The maximum and minimum values are the highest and lowest values that a function can reach over a particular domain.

For example, in a quadratic function, the maximum or minimum value is the highest or lowest point on the graph, respectively.

If a function has a maximum value, it means that the function reaches its highest point at a certain value of x.

On the other hand, if a function has a minimum value, it means that the function reaches its lowest point at a certain value of x.

Here we have

(A) y = x²-6x +19  

At x = 3

y = (3)² - 6(3) + 19  

= 9 - 18 + 19 = 10

(B) y = -4x²+24x -21

At x = 3

y = -4 (3)² + 24(3) - 21

= - 4(9) + 72 - 21

= 15

(C) y= -2x² +20x -49

At x = 3

y = - 2 (3)² + 20(3) - 49

= - 18 + 60 - 49

= - 7

(D) y = 2x² -3x +7    

At x = 3

y = 2(3)³ - 3(3) + 7

= 18 - 9 + 7

= 16

Therefore,

The x = 3 the quadratic equation D) y = 2x² -3x +7 will have maximum value.
