The temperature 6 hours after day break is 53 degrees

Step-by-step explanation:

The temperature was 65 degrees at daybreak. Then it dropped two degrees per hour until dusk. This decrease in temperature can be modeled by the equation,

y = -2x + 65

according to this equation

y= temperature after day break

x= no of hours ( in this case 6)

So equation becomes

y= -2 (6) +65

y=  65- 12

y=   53 degrees

So the temperature 6 hours after day break is 53 degrees

Ok so to start you plug in what’s in the parentheses for x

4c=8-5(4c)
2-k=8-5(2-k)
4p+3=8-5(4p+3)

In the first one you distribute the -5
4c=8-20c
Then add 20c to both sides
24c=8
And divide by 24
C=8/24 or 1/3

Distributing the -5 on the second one gets you
2-k=8-10+5k
Then you combine like terms
2-k=-2+5k
Subtract 5k from both sides
2-6k=-2
Subtract 2 from both sides
-6k=-4
Divide by -6
K=4/6 or 2/3

and lastly the equation is 4p+3=8-5(4p+3)

So you distribute -5
4p+3=8-20p-15
Combine like terms
4p+3=-20p-7
Add 20p to both sides
24p+3=-7
Subtract 3 from both sides
24p=-10
And then divide by 24
P= -10/24 or -5/12

Answer:

Graph (a)

Step-by-step explanation:

When we take x = 0 and replace in the given formula we get:

y = 0.5 (0.5)ˣ = 0.5 (0.5)⁰ = 0.5 · 1 = 0.5  and this corresponds to graph (a).

God with you!!!

A point is dilated with respect to the origin. Determine the value of K and state whether the dilation is an expansion or contra
vlabodo [156]
Scale Factor (K) = (new length/measure)/ (original length/measure)
for x-coordinate  = 8/2 = 4
for y-coordinate  = 16/4 = 4

K=4, expansion

K is the representation of "scale factor". Scale factor is the ratio of the lengths involved of the similar figures. It can be used to identify the kind of dilation, whether it is contraction or expansion. If the Scale Factor is greater than 1, then that means expansion and if it is less than 1, then it signifies contraction.
