Help Me I am really confused on how to solve this math problem

Answer:

e(x) = d(x)+4

Step-by-step explanation:

d(x) = ( x +2)^2 -4

Add 4 to each side

d(x) +4 =  ( x +2)^2 -4+4

d(x) +4 =  ( x +2)^2

We know that (x=2)^2 = e(x)

d(x) +4 =  e(x)

e(x) = d(x)+4

Reorder the following equations in ascending order of steepness: y= 15x + 5 y= 0.15x - 1 y=x y= x + 100
Gre4nikov [31]

Answer:

y= 0.15x - 1, y = x, y = x + 100, y = 15x + 5.

Step-by-step explanation:

When the slope of a line is less than 1 (if the slope is a decimal), the slope will not be steep. But when the slope is more than 1, the slope will be steeper than the average.

According to that rule, the steepest will be y = 15x + 5.

The next steepest equations will be y = x and y = x + 100 (they are both at the same degree of steepness; the intercept does not impact the steepness of the line).

The least steepest will bey = 0.15x - 1.

So, the order, from least steep to most steep, will be y= 0.15x - 1, y = x, y = x + 100, y = 15x + 5.

Hope this helps!

Step-by-step explanation:

given,

measures of 3 angles of triangle,

angle 1 = 3x

angle 2 = 2x + 15°

angle 3 = 3x + 5 °

sum of the angles should be 180°

so,

angle 1 + 2 + 3 = 180°

after inserting the values we got,

3x + 2x + 15 + 3x + 5 = 180°

→ 8x + 20 = 180°

→ 8x = 180 - 20 = 160°

→ x = 160/8 = 2

→ x = 20

therefore,

angle

1 = 3x = 3 × 20 = 60

2 = 2x + 15 = 2(20) + 15 = 55°

3 = 3x + 5 = 3(20) + 5 = 65°

as given,

their sum should be 180° so,

60 + 55 + 65 = 180°

Step-by-step explanation:

First, we add all of the ingredients and we have 31 1/8. Now, we divide this by 8 because there are 8 hikers. Our answer is 3.890625 (Of course we can always round).
