A.) 23 degrees Celsius

b.) y=23-5x

btw I'd rearrange this as

y= -5x+23

If you want to find changes in y, let's compare differences when we change the x.

For example, if x=1

y= -5(1)+23

-5+23=18

So, when x=1, y=18

Now, let's have x=2

y= -5(2)+23

-10+23=13

So, when x=2, y=13

Let's compare the difference in y by subtraction.

18-13=5

So, with every kilometer that you fly up from the surface, the temperature decreases by 5°C

Answer:

i)  = 23 °C

ii) = 4.4° C

Step-by-step explanation:

i) The temperature on the surface of the planet.

At the surface of the planet the height is Zero

Therefore, X = 0

Thus; using the equation, the temperature, y will be;

y = 23 - 5x

y = 23 - 5(0)

 <u> = 23 °C</u>

ii) the temperature change for every kilometer from the surface,

From the equation;

y = 23 - 5x

we take, y to be 1

Therefore;

1 = 23 -5x , subtracting 23 on both sides we get

-22 = -5x

x = -22/-5

<u>  = 4.4° C</u>

If x-3 is a factor of x3+4x2+kx-30.Find the value of k.​
Bogdan [553]

Answer:

k=-11

Step-by-step explanation:

x^{3}+4x^{2}+kx-30

if x-3 is a factor,

(3)^{3}+4(3)^{2}+k(3)-30=0\\27+4*9+3k-30=0\\27+36+3k-30=0\\33+3k=0\\3k=-33\\k=-11

What is the slope of a line that is perpendicular to the line 2x-4y=24
DanielleElmas [232]

Answer: y= -2x + 24

Step-by-step explanation

2x - 4y = 24

subtract 2x from both sides

divide 4y by 4y to get y by itself

then you get y= -2x + 24

OLEGan [10]

Answer:

3

Step-by-step explanation:

To solve f(-1), entails to replace x by -1 in the function

f(-1)= (-1)^2 - (-1)+ 1

= 1 + 1 + 1

= 3
