Vsevolod [243]

~Hello There!~

area of parallelogram = base x height

area = 9.2 x 3.8

area = 34.96cm^2

perimeter = 9.2 + 9.2 + 4.1 + 4.1

perimeter = 26.6cm

Hope This Helps You!

Good Luck :)

Have A Great Day ^_^

Help! Find x, y, z <br> Worth 20 points
GenaCL600 [577]

Answer:

x= 113

y= 67

z= 49

Step-by-step explanation:

a triangle equals to 180° so lets start with the triangle that has two given degrees

28 + 39 + x = 180 solve

x = 113

no we can find y by using x + y = 180 since it's a straight line

we know the value of x so 113 + y = 180. solve.

y= 67

now do the same thing we did from the start since we have two given degrees on the other triangle.

67 + 64 + z = 180

z= 49

There are 118 boys and 121 girls signed up for a volleyball league. The coaches first make teams of 9 players and then assign an
AleksandrR [38]
What the question here? If how many team are there it would go
118+121=9+10p
239=9+10p
Subtract 9 from both sides
230=10p
Divide by 10
23=p
Correct form
P=23

NEED HELP NOW!!!!
Dovator [93]

Answer:

f(x) = -3x --->#6

f(x) = |x-1|+3 --->#5

f(x) = √(x+3) --->#3

1/2x² --->#1

f(x) = (x+1)²-3 --->#4

4|x|--->#2

Step-by-step explanation:

Recall for transformations:

  • Adding a number outside the function moves it up
  • Subtracting a number outside the function moves it down
  • Adding inside the function moves it to the left
  • Subtracting inside the function moves it to the right
  • Multiplying to the function by a number less than 1 compresses
  • Multiplying to a function by a number greater than 1 stretched it
  • Multiplying by a negative flips the graph

f(x) = -3x

This is multiplication by a number greater than 1 and a negative so this stretches and flip. This is #6, a reflection.

f(x) = |x-1|+3

Subtraction inside the function shifts it to the right 1 and addition outside shifts it up 3. This is #5.

f(x) = √(x+3)

Addition inside the function shifts it to the left 3. This is #3

1/2x²

Multiplication by 1/2 which is less than 1 compresses it. This is #1.

f(x) = (x+1)²-3

Addition inside the function shifts the function to the left once. This is #4.

4|x|

Multiplying by 4, a number greater than 1, stretches it. This is #2.
