Quadrilateral W X Y Z is shown. Diagonals are drawn from point W to point Y and from point Z to point X and intersect at point C. Line segments Z C and C X are congruent. The length of W C is 2 x + 5 and the length of C Y is 3 x + 2. In quadrilateral WXYZ, WC = 2x + 5 and CY = 3x + 2. What must x equal for quadrilateral WXYZ to be a parallelogram? x =

Answers

The value of x must be 3, for quadrilateral WXYZ to be a parallelogram

The given parameters are:

[tex]\mathbf{CY = 3x + 2}[/tex]

[tex]\mathbf{WC = 2x + 5}[/tex]

From the question, we understand that:

Segments ZC and CX are congruent

This means that:

Segments WC and CY are congruent

So, we have:

[tex]\mathbf{WC = CY}[/tex]

This gives

[tex]\mathbf{3x +2 = 2x + 5}[/tex]

Collect like terms

[tex]\mathbf{3x + 2x =-2 + 5}[/tex]

[tex]\mathbf{x =3}[/tex]

Hence, the value of x must be 3, for quadrilateral WXYZ to be a parallelogram

Betty is baking cakes to sell slices in her bakery. Each cake has 8 slices. She carefully adds an icing design, using 1/3 cup of icing for each slice. If she plans to bake 4 1/2 cakes, how many cups of icing will she use?

Answers

Answer: 12 cups

Step-by-step explanation:

Number of slices in a cake = 8 slices

Number of cups of icing used by each slice = 1/3

Number of cups of icing for each cake will then be:

= 1/3 × 8

= 8/3

= 2 2/3 cups of icing

If she plans to bake 4 1/2 cakes, the number of cups of icing will she use will be:

= 4 1/2 × 2 2/3

= 9/2 × 8/3

= 72/6

= 12 cups of icing

What is the equation linear function in point-slope form M=-1/5 and f(0)=7

Answers

Answer:

y-7= -1/5x

Step-by-step explanation:

general formula (y-y1)= m(x-x1)

m is the slope and in this case m=-1/5

(x1, y1) is a point on thhe line in this case is (0, 7) because f(x)=y

substitute your given in the equation

(y-7) = -1/5(x-0)

y-7= -1/5x

Step-by-step explanation:

....................

You need to follow the order of operations, so you would solve what is in the parentheses first. (I'm assuming that is the variable x in 2x and not a multiplication symbol. If it is, then just multiply 5 by 3 to get 15, and then multiply that by 2 to get 30) This will give you 15. Then you multiply 2x by 15 to get 30x.

Answer:

yes

Step-by-step explanation:

For some integer n, the squirrel lands on numbers that are ...

5n +6

We want to see if n is an integer when ...

5n +6 = 101

5n = 95

n = 19 . . . . yes, an integral number of jumps will get the squirrel to 101

Solve the equation
x2 + 4x - 7 = 0
by completing the square.
Give your answers correct to 2 decimal places.

Answers

Answer:

x ≈ 1.32, x ≈ - 5.32

Step-by-step explanation:

Given

x² + 4x - 7 = 0 ( add 7 to both sides )

x² + 4x = 7

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(2)x + 4 = 7 + 4

(x + 2)² = 11 ( take the square root of both sides )

x + 2 = ± [tex]\sqrt11}[/tex] ( subtract 2 from both sides )

x = - 2 ± [tex]\sqrt{11}[/tex]

Thus

x = - 2 - [tex]\sqrt{11}[/tex] ≈ - 5.32 ( to 2 dec. places )

x = - 2 + [tex]\sqrt{11}[/tex] ≈ 1.32 ( to 2 dec. places )
