Answer:

y = -2x + 28

Step-by-step explanation:

We are given the slope and a point on the line so first we use the point-slope form :-

y - y1 = m(x - x1)

Substituting the given values:-

y - 12 = -2(x - 8)

Now convert to the slope-intercept form (which is y = mx + c):-

y = -2x + 16 + 12

y = -2x + 28   (answer)

perimetrul unui paralelogram este de 30 cm.una dintre laturi are lungimea de 6 metri . dterminati lungimile celolrarte laturi
zzz [600]

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

1. By definition, the opposite sides of a parallelogram are parallel and have equal length.

2. The figure attached shows that the opposite sides with equal length are:

a=c\\b=d

3. Keeping this on mind, you have that the side <em>c</em> and <em>a</em> are equal and measure six centimeters.

4. To find the length of the other sides, you must apply the following formula for calculate the perimeter of a parallelogram:

P=2(a+b)

4. If you solve for <em>b</em>, you will obtain the measure of <em>b </em>and<em> d:</em>

30cm=2(6cm+b)\\30cm=12cm+2b\\b=9cm

Therefore the answer is:

 The lengths of the sides are: 6 cm, 6 cm, 9 cm and 9 cm.

Can someone please help me with this
Alex_Xolod [135]

Answer:

  135°

Step-by-step explanation:

The reference angle appears to be about 45°, so a reasonable estimate of the angle size is 180° -45° = 135°.

__

You can do an eyeball comparison with the figure attached to see that the angle is about 135°

This is also the value I see when I place my protractor against the screen.

Yu and Elena each bought between 7 and 9 yards of ribbon. Yu
Mumz [18]

Given: Yu, Nailah, and Elena each bought between 7 and 9 yards of ribbon  Yu bought 3 pieces of ribbon. Nailah bought 5 pieces of ribbon. Elena bought 6 pieces of ribbon.

To find: Who can buy which ribbon

Solution:

Ribbon Sizes

1 2/3 = 5/3  yard

4/5  yard

3 1/2  = 7/2 Yard

Yu, Nailah, and Elena each bought between 7 and 9 yards of ribbon

Yu bought 3 pieces of ribbon

=> 3 * 5/3  = 5

  3 * 4/5  = 2.4

  3 * 7/2   = 10.5

Nailah  bought 5 pieces of ribbon

=> 5 * 5/3  = 8.33

   5 * 4/5  =  4

   5 * 7 /2   = 17.5

Elena bought 6 pieces of ribbon

=> 6 * 5/3  = 10

  6 * 4/5  = 4.8

  6 * 7 /2   = 21

Only value between 7 & 9 is 5 * 5/3  = 8.33

hence Nailah only can buy 1 2/3 = 5/3  yard ribbon

or there is some mistake in the data
