Answer:

y = 2/3x + 4

Step-by-step explanation:

Slope-intercept form of a line:

y = mx + bwhere m = slope and b = y-intercept

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:

Slope formula: [tex]\displaystyle \bf \frac{y_2-y_1}{x_2-x_1}[/tex]

Plug the two points into the formula.

[tex]\displaystyle \frac{4-0}{0-(-6)}[/tex]

Subtract and simplify this fraction.

[tex]\displaystyle \frac{4}{6} =\frac{2}{3}[/tex]

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.

y = 2/3x + 4

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

Answer:

y = 2/3x + 4

Step-by-step explanation:

Slope-intercept form of a line:

y = mx + b

where m = slope and b = y-intercept

what is 3/4b>15 solution

Answers

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

How to solve the inequality?

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.

which of the following quadratic will have a maximum value at x=3
(A) y=x^2-6x+19
(B) y=-4x^2+24x-21
(C) y=-2x^2+20x-49
(D) y=2x^2-3x+7

Answers

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.

Step-by-step explanation:

   Divide the number by 100 (move the decimal place two places to the left).

Answer- 171.75
You multiply your original cost (229) by the percent it’s on sale for (.25) then you get $57.25. That is how much is being taken off of the original price so you would subtract 229 by 57.25 to get your answer of $171.75.

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.

(e) A cable customer feels that the monthly cost of cable TV increased the most. A grocery customer feels that the cost of a dozen eggs increased the most. Is it possible for both customers to be correct? Explain your response in one or two complete sentences.

Answers

Answer and explanation:

Cable tv cost changed by $67-$55= $12= 12/55×100=21.818%

Cable TV cost increased by 21.818% of original cost

Dozen of eggs cost changed by $2.19-$1.79= $0.4= 0.4/1.79×100= 22.636%

Dozen of eggs cost increased by 22.636% of original cost

Therefore both customers can't be correct, cost of a dozen of eggs increased the most.

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

If Earth's total mass is 6 x 10^24 kg, what proportion of this is lost every year?

Answers

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.
