Answer: SSS congruence postulate

Step-by-step explanation:

In the given picture , we have two triangles \triangle{QDJ}\text{ and}\triangle{MCW}.

In \triangle{QDJ}\text{ and}\triangle{MCW}, we have

\overline{QJ}\cong\overline{MW}\\\\\overline{DJ}\cong\overline{CW}\\\\\overline{QD}\cong\overline{MC}

Then by SSS congruence postulate , we have

\triangle{QDJ}\cong\triangle{MCW}

SSS congruence postulate says that any two triangles are congruent if all three sides in first triangle are congruent to the corresponding sides in the second.

The correct congruence statement is SSS, or Side-Side-Side. We see that lines QD and MC are equivalent, QJ and MW are equivalent, and lines DJ and CW are equivalent

Kyla used 550 grams of wool to knit a sweater, a hat, and a scarf. For the hat she used 5 times less wool than the sweater and 5
Brrunno [24]
This is the concept of algebra, to calculate the proportion of wool in each item we proceed as follows;
Let the amount of wool used for hat be x
amount of wool in sweater will be 5x
the amount of wool used in scarf will be x-5
 therefore the total amount of wool will be:
x+5x+(x-5)=550
x+5x+x-5=550
7x-5=550
7x=550+5
7x=555
hence;
x=555/7
x=79
the amount used in hat x=79g
amount used in sweater 5x=395g
amount used in scarf=79-5=74g

Find the 9th term of the geometric sequence 2, -10 50 -250
tigry1 [53]

Answer:

781250

Step-by-step explanation:

We first need to find the common ratio

-10 /2 = -5

50 / -10 = -5

The common ratio is -5

an = a (r) ^ (n-1)

a9 = 2 ( -5) ^(9-1)

     = 2 (-5)^8

      =781250

To solve this problem you must apply the proccedure shown below:

You must switch the variables, and then, you must solve for y, as following:

x=-\frac{1}{2} \sqrt{y} +3\\ (x-3)^{2} = (\frac{1}{2}\sqrt{y})^{2}   \\ y=4x^{2} -24x+36\\ f^{-1}  (x)=4x^{2} -24x+36

Therefore, as you can see, the answer is: f^{-1} (x)= 4x^{2} -24x+36
