Answer:

1. [tex]x-3=-15[/tex]
2.[tex]2x=-24[/tex]
3.[tex]2x-3=-27[/tex]

Step-by-step explanation:

Given the following question:

[tex]2x+9=-15[/tex]

To find three equations that have the same solution as the given equation we have to first solve the equation.

[tex]2x+9=-15[/tex]
[tex]9-9=0[/tex]
[tex]-15-9=-24[/tex]
[tex]2x=-24[/tex]
[tex]2x\div2=x[/tex]
[tex]-24\div2=-12[/tex]
[tex]x=-12[/tex]

Equation one:
[tex]x-3=-15[/tex]
[tex]-3+3=0[/tex]
[tex]-15+3=-12[/tex]
[tex]x=-12[/tex]

Equation two:
[tex]2x=-24[/tex]
[tex]2x\div2=x[/tex]
[tex]-24\div2=-12[/tex]
[tex]x=-12[/tex]

Equation three:
[tex]2x-3=-27[/tex]
[tex]-3+3=0[/tex]
[tex]-27+3=-24[/tex]
[tex]-24\div2=-12[/tex]
[tex]x=-12[/tex]

16 sq ft = 2 ft x 8 ft

               4 ft x 4 ft

but..

4 ft x 4 ft x 4 ft = 64 cubic ft

So 4 cannot be the height of this crate.

h represents the height of the crate (defined variable)

2 ft x 8 ft x h = 48 cubic ft

16h = 48

h = 3 ft

The height of the crate is 3 feet.

Check:

2 ft x 8 ft x 3 ft = 48 ft ³

Answer:

Step-by-step explanation:

m∠AED = (360-2(63))/2

m∠AED = 117°

solve for first:

(4x - 3)

(4(30) - 3)

117° ............matches.

solve for third:

5x - 33

5(30) - 33

117° ........matches

Hence the first option and third is correct. rest two are wrong.

The table is an illustration of an exponential function

The equation of the table is [tex]y = 148 * 0.997^x[/tex]

Given that 1995 corresponds to x = 0, then

The initial value (a) of the function is:

a = 148.0

The equation of the function is:

[tex]y = ab^x[/tex]

When x= 1, we have:

[tex]147.6 = ab^1[/tex]

[tex]147.6 = ab[/tex]

This gives

[tex]147.6 = 148b[/tex]

Divide both sides by 148

[tex]b = 0.997[/tex]

Hence, the equation of the table is:

[tex]y = 148 * 0.997^x[/tex]

Step-by-step explanation:

Harrison's Butcher Shop sells 1/3 pounds of bee

for $1.50. If you need to buy 5 pounds of beet

for a cookout, how much would the beef cost?

Setup a proportion to answer the problem.

$27.50

$7.50

$15.00

$22.50

1.50 * 3 = 4.5 (cost 1 pound)

4.5 * 5 = 22.5 (total cost)

The cost of 5 pounds of beef for a cookout given the cost of 1/3 pounds is $22.50

Equate the ratio

1/3 : 1.50 = 5 : x

1/3 ÷ 1.50 = 5/x

1/3 × 1/1.50 = 5/x

1/4.5 = 5/x

1 × x = 4.5 × 5

x = $22.5

Answer:

The standard deviation of the residuals calculates how much the data points spread around the regression line. The result is used to measure the error of the regression line's predictability.

Step-by-step explanation:

STDEV. S(errors) = (SQRT(1 minus R-squared)) x STDEV. S(Y). So, if you know the standard deviation of Y, and you know the correlation between Y and X, you can figure out what the standard deviation of the errors would be be if you regressed Y on X.

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

The value for R in the table which is most likely to indicate an association between the conditional variables is 0.79.

The association between the conditional variables, exist when the relative frequencies between the two variables are not similar.

The more the difference in the values shows the stronger the association between two.

The table given in the problem is attached below. The given option for the R value in the table is, 0.09,  0.10,  0.13, and 0.79.

As it is known that the bigger the difference, gives the stronger the association. Here, the R value with 0.79 is the most opposite to the value above the R.

Hence, the value for R in the table which is most likely to indicate an association between the conditional variables is 0.79.

The first step of finding the percent tip, we must find how much tip she paid:

     Tip = $38.61 - $33 = $5.61

To find the percent tip, we must divide the tip amount by the amount she paid before the tip

     $5.61 / $33 = 0.17 --> 17%

Thus the percent tip is 17%

Answer:

The question simplified is 3x.

or 3

Step-by-step explanation:

Answer:

(f-g)(x)= f(x) - g(x)

= x^2 + 8x - ( 3x - 5)

= x^2 + 8x - 3x + 5

= x^2 + 5x + 5

(f-g)(x)= x^2 + 5x + 5

The required expression of (f-g)(x) = x^2+5x+5.

f(x) = X^2+8x; g(x) = 3x - 5
(f-g)(x) to determine.

It is defined as the number of composition, constitute the whole.

Here, (f-g)(x)= f(x)-g(x)
                  = x^2+8x-3x+5
                  = x^2 + 5x + 5

Thus, the required expression of (f-g)(x) = x^2+5x+5.

Step-by-step explanation:

are you sure the fuel consumption is given by 6,8 km/l ?

normally it is given by l/100km.

but ok, let's assume this is correct.

it would mean the car can drive 6,8 km with every liter of fuel in the tank.

how many liters will the car need to go 450 km ?

well, as many liters as 6,8 fits into 450 :

450/6,8 = 66.17647059... liters

this is not a very fuel efficient car ...
