Answer:

The equation is y=x-9

Step-by-step explanation:

If we want a line parallel to the line in the problem it will have the same slope. The equation given in the problem is already in slope intercept form so we can take the slope for the new equation directly from this equation.

The slope-intercept form of a linear equation is:  y=mx+b

Where  m  is the slope and  b  is the y-intercept value.  

y=1x-2

Therefore the slope is  

m=1

We can now use the point-slope formula to write the equation of the parallel line:

The point-slope formula states:  

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

Where  m  is the slope and  (x1,y1) is a point the line passes through.  

Substituting the information from the problem gives:

(y- (-7)=1(x-2)

(y+7)=1(x-2)

Or, we can solve for  y  to put the equation in slope-intercept form:

y+7=x-2

y+7-7=x-2-7

y+0=x-9

y=x-9

The perimeter of a rectangular painting is 272 cm if the width of the painting is 61 cm, what is its length?
Semmy [17]

Answer: length = 75 cm

Step-by-step explanation:

61 x 2 = 122

272-122= 150

150 divided by 2 = 75

check: 75+61= 136

136 x 2 = 272

Answer:

<em>See the Venn diagram attached</em>

<u>Numbers given:</u>

  • <em>Total</em>: 100
  • Either a cat of a fish: 70
  • Cat: 46
  • Cat and fish: 16

<u>Neither a cat or a fish:</u> 100 - 70 = 30

<u>Fish:</u> 70 - (46 + 16) = 70 - 62 = 8

<u>Required probabilities are:</u>

  • a) P(neither) = 30/100 = 0.3
  • b) P(f) = (16 + 8)/100 = 0.24
  • c) P(f not c) = 8/100 = 0.08
