Answer with explanation:

Ordered Pair = {(–8, –6), (–5, 2), (–8, 1), (7, 3)}

Preimage (x)                                 Image(y)

  -8                                                    -6

  -5                                                      2

   -8                                                     1

    7                                                       3

Element , -8 more than 1 image that is , -6 and 1.

→→So, if an element in a set that is in preimage, has more than one image then that relation is not a function.

So, the given relation is not a function.

⇒→Ordered Pair ={(–3, –6), (–1, –6), (5, –6), (8, –6)}

Preimage (x)                                 Image(y)

 -3                                                      -6

 -1                                                       -6

  5                                                        -6

 8                                                         -6

All the elements in preimage has same image that is , -6.No two same element in preimage has more than one image.

So, the given relation is a function.

So, the relation is a Function.

For altitudes up to 36,000 feet, the relationship between ground temperature and atmospheric
Verizon [17]

Answer:

The equation for a is a=-\frac{2000}{7}*(t-g)

The altitute is 101,428.57 feet

Step-by-step explanation:

You know that the relationship between ground temperature and atmospheric  temperature can be described by the formula

t = -0.0035a +g

where:

  • t is the atmospheric  temperature in degrees Fahrenheit
  • a is the altitude, in feet, at which the atmospheric temperature is  measured
  • g is the ground temperature in degrees Fahrenheit.

Solving the equation for a:

-0.0035a +g=t

-0.0035a= t - g

a=\frac{t-g}{-0.0035}

a=-\frac{2000}{7}*(t-g)

<u><em>The equation for a is </em></u>a=-\frac{2000}{7}*(t-g)<u><em></em></u>

If the atmospheric temperature is -305 °F and the ground temperature is 50 °F, then t= -305 °F and g= 50 °F

Replacing in the equation for a you get:

a=-\frac{2000}{7}*(-305-50)

a=-\frac{2000}{7}*(-355)

a= 101,428.57

<u><em>The altitute is 101,428.57 feet</em></u>

Which part of the graph best represents the solution set to the system of inequalities y&lt;_ x+1 and y+x&lt;_ -1
Pavel [41]

Hello!

Remember that the symbols: ≤ and ≥ are graphed as a solid line. While the symbols: < and > are graphed as a dotted line.

Also, before graphing, it would be better to convert both equations to slope-intercept form.

y ≤ x + 1 is already in slope-intercept form.

y + x ≤ -1 is not written in slope-intercept form. (Slope-intercept form: y = mx + b)

y + x ≤ - 1 (subtract x from both sides)

y ≤ -x - 1

Graphing those lines, you get the graph below. You can see that Part C best represents the solution set systems of inequalities, because that is where both of the shaded lines intersect.

Answer: Part C
