Find f(h(-1)) 2 -9 11 -11

kumpel [21]

Answer:

(d) -11

Step-by-step explanation:

Each of the functions is evaluated in the usual way: put the number where the variable is in the expression and simplify.

h(-1) = -2(-1)² -3(-1) +1 = -2 +3 +1 = 2

f(2) = (2(2) +7)/(2 -3) = 11/-1 = -11

Then f(h(-1)) is ...

f(h(-1)) = f(2) = -11

The length of OM is 4/3 the length of OJ, and the length of ON is 4/3 the length of OK. Thus, two pairs of sides from the triangles are proportional to each other.

Also, angle O from one of the triangles is equal to angle O of the other triangle because they are the same angle.

Thus, the two triangles are similar by SAS (side-angle-side) similarity theorem. This theorem is quite similar to the SAS congruence theorem.

To make a similarity statement, we just have to match corresponding parts when naming the triangle.

Similarity statement: ΔOJK~ΔOMN

Emily brought $35 to the fair. At the fair, she spent $16 on ride tickets and she also bought lunch. She had $7 when she left th

MatroZZZ [7]

Answer:

Emily spend $12 on lunch.

The correct option is Option A i.e 23 plus x equals 35; x equals 12

Step-by-step explanation:

Let amount spent on Lunch = x

Total money Emily brought to the fair = $35

Money Spend on ride tickets and lunch = 16+x

Money Left with Emily = $ 7

We need to find how much Emily spend on lunch

SO,

We can write the equation $16+x+7=35\\$

As, total money is 35 and $7 are still with emily

Solving to find value of x

$16+x+7=35\\x+23=35\\x=35-23\\x=12$

So, Emily spend $12 on lunch.

The correct option is Option A i.e 23 plus x equals 35; x equals 12

goblinko [34]

Answer:

12 Pieces

Step-by-step explanation:

Number of candies in Jane's bag = x

she gives 8 to her friend;

x - 8

Then jane's grandmother buys 5 more pieces than jane had originally; add (x + 5)

x - 8 + x + 5

Now jane has 27 pieces of candy

x - 8 + x + 5 = 27

Solve for x;

x - 8 + x + 5 = 27

2x - 3 = 27

2x = 27 -3

2x = 24

x = 12
