Answer:

Its 5

Step-by-step explanation:

you substitute the X

so you would write 2(2)+1

you would then multiply 2×2 which gives you 4

then add 4+1=5

It’s 5 y=2(2)+1 you have to substitute the x with 2

Q # 14. help me please to resolve

ivolga24 [154]

A(n) =2+9(n-1)= 2 + 9n - 9= 9n -7

A(n-1)= 2+9[(n-1)-1]= 2 + 9(n-2)= 2+ 9n - 18= 9n -16

A(n)- A(n-1)= (9n-7)-(9n-16) = -7+16=9

A(n)= A(n-1) +9 is the answer

QUESTIONS The average price of wheat per metric ton in 2012 was $30575. Demand in millions of metric tons) in 2012 was 672. The

soldi70 [24.7K]

Answer: -0.9 ; inelastic

Explanation:

Given:

The average price of wheat per metric ton in 2012 = $305.75

Demand (in millions of metric tons) in 2012 = 672

The average price of wheat per metric ton in 2013 = $291.56

Demand (in millions of metric tons) in 2013 = 700

We will compute the elasticity using the following formula:

ε = $\frac{\frac{(Q_{2} - Q_{1})}{\frac{(Q_{2} +Q_{1})}{2}}}{\frac{(P_{2} - P_{1})}{\frac{(P_{2} +P_{1})}{2}}}$

ε = $\frac{\Delta Q}{\Delta P}$

Now , we'll first compute $\Delta Q$

i.e. $\frac{\Delta Q}{\Delta P}$ = $\frac{(700 - 672)}{\frac{(700 +672)}{2}}$

$\Delta Q$ = 0.04081

Similarly for $\Delta P$

i.e. $\Delta P$ = $\frac{(291.56 - 305.75)}{\frac{(261.56 +305.75)}{2}}$

$\Delta P$ = -0.0475

ε = $\frac{0.04081}{-0.0475}$

ε = -0.859 $\simeq$ -0.9

$\because$ we know that ;

If, ε > 1 ⇒ Elastic

ε < 1 ⇒ Inelastic

ε = 1 ⇒ unit elastic

$\because$ Here , ε = -0.859 $\simeq$ -0.9

Therefore ε is inelastic.

Which of the following coordinate points is the point of intersection of these two lines? y - 6x = -4 and y - 2x = 8

Nimfa-mama [501]

Answer:

(x,y)=(3,14)

Step-by-step explanation:

y-6x=-4 , y=-4+6x

y-2x=8, y=8+2x

(y=)-4+6x=8+2x

6x-2x=8+4

4x=12

x=12/4

x=3, then

y=-4+6*3=-4+18=14

(x,y)=(3,14)
