Answer:

a>4 or a < 8

Step-by-step explanation:

We can start with the inequality on the left

-a + 2(4+3a) > 28

expand using the distributive property

-a + 8 + 6a > 28

5a + 8 > 28

subtract 8 from both sides to isolate the variable and its coefficient

5a > 20

divide both sides by 5 to isolate a

a > 4

moving on to the inequality on the right

2a - (3a+4) > -12

treat the minus sign as a -1

2a + (-1)(3a+4) > - 12

expand

2a - 3a - 4 > - 12

-a - 4 > -12

add 4 to both sides to isolate a and its coefficient

-a > - 8

multiply both sides by -1 but change the sign because we are multiplying by a negative number

a < 8

The Willis Tower is 1450 feet tall. Jeff
IgorLugansk [536]

Answer:

  something smaller than 1/483.33, possibly 1/500

Step-by-step explanation:

For the model to fit into the car, the scale must be less than ...

  (3 ft)/(1450 ft) = 1/483.33

It might be convenient for Jeff to use a scale factor of 1 : 500. This would result in a model ...

  (1450 ft)/500 · (12 in/ft) = 34.8 in

leaving about 1.2 inches of clearance in his mother's car.

What is the slope of a line that is perpendicular to the line y = 1?
Viktor [21]
Y = 1

Using y = mx + c.

Compare to y = 1,    y = 0x + 1 ,

We can see that the slope m = 0 and the vertical intercept, c = 1.

For the line perpendicular to  y = 1

Condition for perpendicularity  m₁m₂ = -1

m₁ = 0,  m₂ = ?

0*m₂ = -1

m₂ = -1/0 = Negative Infinite or Infinite

Slope of line perpendicular to y = 1, is  = Infinite.

Which of the following is equal to the rational expression when x*-2 or 3?<br> X^2 +5x+6<br> X^2-X-6
trasher [3.6K]

Answer:

Step-by-step explanation:

x=-2, x=3

---------------

x^2+5x+6=(-2)^2+5(-2)+6=(-2)(-2)-10+6=4-10+6=-6+6=0

x^2+5x+6=3^2+5(3)+6=9+15+6=24+6=30

---------------------------------------------------------------

x^2-x-6=(-2)^2-(-2)-6=4+2-6=6-6=0

x^2-x-6=3^2-3-6=9-3-6=6-6=0

-----------------------------------------------------
