PLEASE HELP !!!!!

Mathematics
1 answer:
Anastaziya [24]2 years ago
8 0

Answer:

  -10%

Step-by-step explanation:

  price elasticity of demand = % change in demand / % change in price

Here, the "price" changes from 15 to 45, so its percent change is ...

  ((new value)/(old value) -1) × 100%

  = (45/15 -1) × 100%

  = 200%

The % change in demand is given as -20%, so the price elasticity is ...

  price elasticity of demand = (-20%)/(200%) = -0.10 = -10%

Write an equation of the line that passes through (2,7) and is parallel to the line shown ( please help !! )
Anna007 [38]

Answer:

y=2x+3

Step-by-step explanation:

We will first need to determine the slope of the line shown.

We know that it passes through the two points (-2, -2) and (1, 4).

Thus, we can use the slope formula to find the slope between the two points:

\displaystyle m=\frac{y_2-y_1}{x_2-x_1}

Let (-2, -2) be (x₁, y₁) and let (1, 4) be (x₂, y₂). Substitute:

\displaystyle m=\frac{4-(-2)}{1-(-2)}=\frac{6}{3}=2

Hence, the slope of the original line was 2.

Since we want the new line to be parallel, the slope of the new line must also be 2.

We know that the slope is 2 and it passes through the point (2, 7).

So, we can use the point-slope form:

y-y_1=m(x-x_1)

We will substitute 2 for m. We will also let (2, 7) be (x₁, y₁). Substitute:

y-7=2(x-2)

Solve for y. Distribute the right:

y-7=2x-4

Add 7 to both sides. Hence, our equation is:

y=2x+3

Step-by-step explanation:

I did this mentally so sorry if it is bad

16 = 20%

+

16 = 20%

= 40% 32 students

40% +40% = 80%

32+ 32 = 64

80+20%

64+16

80 Students are in the band class
