aliina [53]3 years ago
4 0

Answer:

 (2h-3k)^2           [(2h-3k)^2] x 6hk             6hk(2h-3k)

------------------ =  ---------------------------   = ------------------------

  5(2h-3k)               5(2h-3k)                             5  

  --------            

   6hk

   

Step-by-step explanation:

after 1st equation, move 6hk to top, this is because (b is 1 in this case):

    a

  -----

    b

------------- = (a/b) / (c/d) = (a/b) * (d/c) = (a*d)/(b*c)

    c

   ----

     d

after 2nd equation, crossed out (2h-3k)

There are 6 ouces of dough and 4 ounces of suase for each person at a party including yourself once you have a total of guest yo
zepelin [54]

Answer:

Number of guests = 13

Sauce = 52 ounces

Dough = 78 ounces

Step-by-step explanation:

you are having a pizza making party. You will need 6 ounces of dough and 4 ounces of sauce for each person at the party (including myself the host) Once you have a total count of guests you have exactly the amount needed for ingredients. the dough and sauce that I have is 130 ounces all together. How many ounces of dough did I buy? Explain How many ounces of sauce did I buy? Explain How many guests are coming to the party? Explain

Dough = 6 ounces

Suase = 4 ounces

Dough + sauce = 6 + 4 = 10

Let x = total number of guests

Dough ingredients + sauce ingredients = 130

10x = 130

Divide both sides by 10

x = 130/10

= 13

x = 13

Number of guests = 13

Total ounces of dough = 6 ounces × 13 guests

= 78 ounces of dough

Total ounces of sauce = 4 ounces × 13 guests

= 52 ounces of sauce

Therefore,

Number of guests = 13

Sauce = 52 ounces

Dough = 78 ounces

Help with this question please. Doesn't make sense at all.​
snow_lady [41]

Answer:

  a. FG ≈ 6.983 cm

  b. FH = 13.16 cm

Step-by-step explanation:

<h3>a)</h3>

Corresponding sides of similar triangles are proportional. This means ...

  FG/GH = CD/DE

  FG = GH(CD/DE) = (9.4 cm)(2.6/3.5) . . . . . . multiply by GH; fill in values

  FG ≈ 6.983 cm

__

<h3>b)</h3>

And ...

  FH/GH = CE/DE

  FH = GH(CE/DE) = (9.4 cm)(4.9/3.5)

  FH = 13.16 cm

__

<em>Additional comment</em>

Corresponding vertices are listed in the same order in the similarity statements. This means, for example, segment FG (which names the first two vertices in the name of ΔFGH) will correspond to segment CD (which names the first two vertices of ΔCDE).

Which represents where f(x) = g(x)? A) f(4) = g(4) and f(0) = g(0) B) f(–4) = g(–4) and f(0) = g(0) C) f(–4) = g(–2) and f(4) =
saul85 [17]

Answer:

B. f(-4) = g(-4), and f(0) = g(0)

Step-by-step explanation:

We are given two functions that have been graphed already. The points on the coordinate plane  where the  curve of g(x) intercepts that of f(x), are the values of x for each function, that would give us the same output (y).

Thus, for f(x) intercepts g(x) at the point where x = -4, y = 4.

Also, f(x) and g(x) intercepts at the point where x = 0, y = 4.

Therefore, the correct answer is f(-4) = g(-4), and f(0) = g(0)

Answer:

Yes, the transformation is a 270°  clockwise rotation

Step-by-step explanation:

(-3, 4) ,( -4, 7) and (-2,7) transformed to (-4, - 3), (-7, -4) and (-7, -2).

Rule for 270° clockwise rotation:

(x, y) --> (- y, x)

A transformation that doesn't change the size or shape of an object.

So answer is:

Yes, the transformation is a 270°  clockwise rotation
