Answer: Wait a minute, Is the answer is 144 cubic centimetres?

Step-by-step explanation: So this is the given formula volumebox = width x length x height. Measure any two sides (length, width or height) of an object or surface in order to get a two-dimensional measurement, then multiply the width, length, and the height: 12*6*2=144 cm^3.

$f-354=1221$ <em>add 354 to both sides</em>

$f+354-354=1221+354\\\\\boxed{f=1,575}\to\boxed{D.}$

Match the sets of points representing one-to-one functions with the sets of points representing their inverse functions. h = {(1

geniusboy [140]

The one-to-one functions given as sets of points and their possible inverse functions are given as
h = { (1,1), (2,2), (3,3), (4,4), (5,5), (6,6)}
g = { (1,3), (2,6), (3,9), (4,12), (5,15), (6,18)}
f = { (1,2), (2,3), (3,4), (4,5), (5,6), (6,7)}
i = { (1,1), (2,3), (3,5), (4,7), (5,9), (6,11)}

h⁻¹ = { (1,1), (2,2), (3,3), (4,4), (5,5), (6,6)}
i⁻¹ = { (1,1), (3,2), (5,3), (7,4), (9,5), (11,6)}
g⁻¹ = {(3,1), (6,2), (9,3), (12,4), (15,5), (18,6)}
f⁻¹ = {(2,1), (3,2), (4,3), (5,4), (6,5), (7,6)}

The inverse function of a given function should have the coordinates reversed.
Therefore the matches between the given functions and their inverse functions are given in the table below.

Write an equation for the line passing through the given point and having the given slope.

Nadusha1986 [10]

Answer: The equation, in "slope-intercept form" ; is:

________________________________________________

→ " y = x + 4 " .

________________________________________________

Step-by-step explanation:

________________________________________________

Use the formula for linear equations; written in "point-slope format" ;

which is:

y − y₁ = m( x − x₁ ) ;

We are given the slope, "m" ; has a value of: "1 " ;

that is; " m = 2 " .

________________________________________________

We are given the coordinates to 1 (one) point on the line; in which the coordinates are in the form of :

" ( x₁ , y₁ ) " ;

→ that given point is: "(10, 6)" ;

in which: x₁ = 10 ;

y₁ = 6 .

→ Given: The slope, "m" equals "1" ; ________________________________________________

Let's plug our known values into the formula:

→ " y − y₁ = m( x − x₁ ) " ;

_______________________________________________

→ As follows:

→ " y − 10 = 1(x − 6) ;

______________________________________________

Now, focus on the "right-hand side of the equation" ;

→ 1(x − 6) = ? ; Simplify.

______________________________________________

Note the "distributive property" of multiplication:

→ a(b + c) = ab + ac ;

As such: " 1(x − 6) = (1*x) + (1 * -6) " ;

= 1x + (-6) ;

= x − 6 ;

[Note that: " 1 x = 1 * x = x " ;

[Note that " + (-6) " = " ( " − 6 " ) .] ;

→ {since: "Adding a negative" is the same as:

"subtracting a positive."} ;

________________________________________________

Now, let us bring down the "left-hand side of the equation" ; &

rewrite the entire equation; as follows:

________________________________________________

→ " y − 10 = x − 6 " ;

________________________________________________

Note: We want to rewrite the equation in "slope-intercept form" ;

that is; " y = mx + b " ;

in which: "y" ; stands alone as a single variable on the "left-hand side" of the equation; with "no coefficients" [except for the "implied coefficient" of " 1 "} ;

"m" is the coefficient of "x" ;

and the "slope of the line" ;

Note that "m" may be a "fraction or decimal" ; and may be "positive or negative.

If the slope is "1" ; (that is "1 over 1" ; or: " $\frac1}{1}$ " ;

then, " m = 1 " ; and we can write " 1x " as simply "x" ; since the implied coefficient is "1" ;

→ since " 1" , multiplied by any value {in our case, any value for "x"} , equals that same value.

________________________________________________

"b" refers to the "y-intercept" of the graph of the equation;

that is; the "y-value" of the point at which the graphed line of the equation crosses the "y-axis" ;

that is, the "y-value" of the coordinates of the point at which the graphed line of the equation crosses the "y-axis" ;

that is, the ["y-value" of the] y-intercept" .

Note that the value of "b" may be positive or negative, and may be a decimal or fraction.

If the value for "b" is negative, the equation can be written in the form:

" y = mx - b " ;

{since: " y = mx + (-b) " is a bit tedious .}

If the y-intercept is "0" ; (i.e. the line crosses the y-axis at the origin, at point: " (0,0) " ;

then we simply write the equation as: "y = mx " ;

________________________________________________

So; we have: → " y − 10 = x − 6 " ;

________________________________________________

→ We want to rewrite our equation in slope-intercept form,

that is; " y = mx + b " ; as explained above.

We can add "10" to each side of the equation ; to isolation the "y" on the "left-hand side" of the equation:

→ " y − 10 + 10 = x − 6 + 10 " ;

to get:

→ " y = x + 4 " ;

________________________________________________

→ which is our answer.

________________________________________________

Note: This answer: " y = x + 4 " ;

→ is written in the "slope-intercept format";

→ " y = mx + b " ;

in which: "y" is isolated as a single variable on the "left-hand side of the equation" ;

The slope of the equation is "1" ; or an implied value of "1" ;

that is; " m = 1 " ;

"b = 4 " ;

→ {that is; the "y-value" of the "y-intercept" — "(0, 4)" — of the graph of the equation is: "4 ".} .

Please explain how you got the answer also, thank you

harina [27]

Answer:

See Explanation

Step-by-step explanation:

You are doing simple math within the square root. For instance where x=-2 you substitute -2 for x then add 2 which gives you 0 leaving you with -6.

for x=2 you end up with "square root 2+2" which gives you 4 and the square root of 4 is 2 so you add -6 to 2 giving you the answer of -4.
