Pls help ive been stuck on this for hours

38 i ised my brain i think

Answer:

28

Step-by-step explanation:

4 / 7 * x = 16

4 * x = 16 * 7

x = 4 * 7

x = 28

Answer:

the answer would be 28 becuase you would factor the numerator and denominator and cancel out the commen factors. i could explain more if needed :)

Answer:

Four over nine looks like 4/9 and 2 over nine looks like 2/9.

Since they have the same denominator, which is 9, 4/9 would be bigger than 2/9, because 4 is bigger than 2.

Step-by-step explanation:

Hope this helps you :)

Answer is 2/3

because

16/3 / 8=2/3

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

Step-by-step explanation:

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

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

Step-by-step explanation:

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) .

(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:

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:

-99%

Step-by-step explanation:

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

8,000 - 80 = 7,920

7,920 / 8,000 = 0.99

0.99 x 100 = 99%

-99%

(they might be asking for just 99% though too!)

You can plug it inot a calculator, or can make a factor tree, in which the 2 factors would be 11, so 11^2=121 and [tex]\sqrt121[/tex]=11

Answer:

11

Step-by-step explanation:

its something you basically have to just memorize and know... i dont know how to explain it, but like basically not all numbers have an even number square root. to have an even number for a square root, the number has to be able to be divided by the same 2 numbers. like 121, for it to have a whole number square root, it has to be able to be divided by 2 same numbers. or doubles... 11 times 11

11 squared is 121

square root of 121 is 11

hope this helps.
