Answer:

h = 209

Step-by-step explanation:

So we want to solve h, therefore, we must get it by itself on one side. We can do that by somehow removing the three that is with h. So how could we do that? Well, by multiplying h/3 by 3, we get h because the threes cancel out. However, whatever we do to one side, we must do it to the other too because then the equation does not hold true. So, 3 x (69 + 2/3) = 209

Answer:

(5,0)

Step-by-step explanation:

Switch the second equation around so it matches up with the first one :

4x-6y = 20

Then solve by elimination :

-2 (2x-3y = 10) = -4x+6y = -20

-4x+3y = -20

+ 4x-6y = 20

--------------------

-3y = 0

y = 0

Plug y as 0 into one equation :

2x-3(0) = 10

2x = 10

x = 5

Your solution would be (5,0) .

[tex]5 - 4x < 95 \\ - 4x < 95 - 5 \\ - 4x = 90 \\ x = - \frac{90}{4} \\ \boxed{ x = - \frac{45}{2} }[/tex]

(A)

Step-by-step explanation:

To be able to compare the growth rates of these two people, we need to develop an equation to describe Ioana's growth history, just like Valentin did.

Let [tex]P_1(5, 102)[/tex] and [tex]P_2(10, 127).[/tex] Using the equation for the slope of a linear function,

[tex]m = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]

and this will represent the growth rate for Ioana. The slope in Valentin's equation also represents the growth rate. Using the values of the points that we picked, we get

[tex]m = \dfrac{127 - 102}{10 - 5} = \dfrac{25}{5} = 5[/tex]

The slope-intercept form of the equation that describes Ioana's growth can be written as

[tex]h_I = 5(a - 5) + b[/tex]

Note that we used (a - 5) instead of the usual variable a because the twins started recording their heights at the age of a = 5. Next, we need to figure out b, essentially Ioana's height at age 5. From the table, we can see that that b = 102. Hence, the equation for Ioana's height is

[tex]h_I = 5(a - 5) + 102[/tex]

Let's compare this with Valentin's equation for his height:

[tex]h_V = 4.5(a - 5) + 104[/tex]

We can see here that the slope for Ioana's equation is larger than Valentin's, which means that Ioana's growth rate is faster than that of Valentin, even though Valentin was taller when they first started.

Answer:

113

Step-by-step explanation:

supplementray means 180-67=113

113

The diagonal line is a straight line which means when another straight line passes through it, both sides will add up to 180

The relationship between the x and y variables in the scatter plot is

approximately linear.

(a) Increase in the y-variable follows from an increase in the x-variable

(b) The regression coefficient is approximately 0.9465

(c) The slope of the regression line is 2.5

(d) The equation of the regression line is approximately; y = 2.5·x + 10.5

(e) If x = 25, the value of y is 73

Reasons:

(a) From the attached graph, we have;

The increase in the x-variable gives a corresponding increase in the y-

variable.

(b) The correlation coefficient is given by plotting the given points using

MS Excel and finding the regression line, from which we have;

The regression coefficient is R ≈ √(0.8958) ≈ 0.9465

(c) The slope of the regression line is given by the slope of the line with

points (7, 28), and (9, 33), as follows;

[tex]Slope = \dfrac{33 - 28}{9 - 7} = 2.5[/tex]

The slope of the regression line is approximately 2.5

(d) Using the slope, m = 2.5, we get;

Equation of regression line, is y - 33 = 2.5·(x - 9)

Which gives;

y - 33 = 2.5·(x - 9) = 2.5·x - 22.5

y = 2.5·x - 22.5 + 33 =

The equation of the line is; y = 2.5·x + 10.5

(e)  If x = 25, we have;

y = 2.5 × 25 + 10.5 = 73

Therefore, if x = 25, y = 73

9 * 11 = 99 dollars for adults.  16 * 5.50 = 88 dollars for kids.

Togther it would be 99 + 88 = 187

Answer:

49 degrees

Step-by-step explanation:

Answer:

m<E = 49°

Step-by-step explanation:

Using the straight angle theorem, we can add the angles measuring 63, 68, and the angle above the 68(let's call it x) add to 180. We can write an equation:

63 + 68 + x = 180

This means:

x = 49

Angle x is alternate interior to angle E, meaning the two are congruent and have the same measure. This means m<E = 49

Answer:

Step-by-step explanation:

Use proportions.

Answer:

False

or

3951

Step-by-step explanation:

F(m) represents an equation that when the "m" is changed within the parenthesis, all the m's in the equation change as well. The function determines the value of the equation.

In this case, "m = 6" or in basic terms:

f(6) = m^5 + 3m^4 - 21m^3 - 12m^3 - 12m^2 = 31m - 33

Replace all m's with 6.

[tex]f(6) = (6)^5 + 3(6)^4 - 21(6)^3 - 12(6)^3 - 12(6)^2 = 31(6) - 33[/tex]

And do the exponents + coefficients.

6^5 = 7776

3(6^4) = 3888

-21(6)^3 = -4536

-12(6)^3 = -2592

-12(6)^2 = -432

31(6) = 186

-33 = -33

Our final equation is:

7776 + 3888 - 4536 - 2592 - 432 = 186 - 33

Add/subtract all together:

4104 = 153

Now because of your question being quite vague, there could be two ways of answering.

One: Determining whether the equation is true or false, which in this case. 4104 does indeed not equal 153, therefore making it false.

Two: Getting one single number, which we would have to subtract 153 from both sides to get the answer:

4104 - 153 = 153 - 153

Since it is going down, it'll be negative.
