Answer:We can fill all the boxes with help of below explanation.

Explanation:

Since here, ABCD is a parallelogram with vertices A, B, C and D and diagonals AC and BD.

Where, it is given A≡(0,0), B≡(a,0) and D≡(b,c)

According to the given figure,

The coordinates of C are (a+b, c) ( since, Both points C and D are equally far from X-axis therefore, they both have same y-coordinate.)

Now, again from the diagram, E is the midpoint of both Diagonals BD and AC.

where, coordinates of E are (\frac{a+b}{2} ,\frac{c}{2})

Thus, by the definition of midpoints AE\cong CE and BE\cong ED.

Also, BD and AC are intersecting at point E.

Therefore AC and BD bisect each other.

Lara bought 3 yards of fabric and a spool of thread for $28.10. If the spool of thread cost $1.25, how much did the fabric cost
Lyrx [107]

Answer: $8.95 per yard of fabric

Step-by-step explanation:

Define the following:

x = cost of fabric per yard

Make an equation:

⇒ 3x + 1.25 = 28.10

⇒ 3x = 26.85

⇒ x = 8.95

∴ $8.95 per yard of fabric

5x-2 what’s the slope and y-int ?
uranmaximum [27]

Answer:

Slope = 5.

y-int = (0, -2).

Step-by-step explanation:

y = 5x - 2

The slope intercept form is

y = mx + b  where m = the slope and b = the y-intercept.

So here,  the slope = 5 and the y-intercept is where y = -2.  That is the point (0, -2).

What is the mistake NEED ANSWER ASAP​
julsineya [31]

Answer:

The answers are in the image.

Step-by-step explanation:

Charlie made the mistake by not getting the equation equal to zero.

x^2 - 9x + 8 = 16

Subtract 16 to both sides making it equal to 0.

x^2 - 9x - 8 = 0

Using Quadratic Formula to Solve for x.
