Answer:
Government
Step-by-step explanation: Macroeconomics is the branch of economics that studies the behavior and performance of an economy as a whole. It focuses on the aggregate changes in the economy such as unemployment, growth rate, gross domestic product and inflation.
Evaluate f(x) when x=2
x = 9y
x + 1.5y = 12
x + y = 9
x + 9y = 12
x = 1.5y
9x + y = 12
x = 1.5y
The system of equations that represents the given statements is
x + 1.5y = 12
x + y = 9
Where x is the number of pencils and y is the number of pens that Shawn bought.
To write an equation:
Given that,
A pencil at a stationery store costs - $1
and A pen costs - $1.50
Shawn spent $12 at the store. He bought a total of 9 items.
So,
Consider number of pencil = x and number of pens = y
Since he bought a total of 9 items, we can add the number of pencils and pens and equate the sum with 9
I.e., x + y = 9 ...(i)
We have cost for a single pencil and a single pen
So, to get the cost for the total number of pencils and pens that he bought, multiply the cost of a single one by the number of pencils and pens. I.e.,
1 × x and 1.50 × y
Since it is given that he spent $12 for both pencils and pens, we can write
x + 1.5 y = 12 ...(ii)
Thus, from equations (i) and (ii), the system we can write
x + 1.5 y = 12
x + y = 9
So, option 2 is the correctset of equations for the given system.

Step-by-step explanation:
x-(-11)
= x+11
= 14+11
= 25
B. y = 2x + 2
C. y = -2x + 1
D. y = -1x + 1
E. y = -3x + 1
Answer:
it would be C. y= -2x+1
Step-by-step explanation:
Y= mx+c
the c would be the y- intercept (0,1)
m is the slope the rise/run in this case the line seems to be going down which means there would be a negative sign you move 2 units down and one right the slope would be -2/1 which is -2
