Answer:

the first one should be (0,-5)

the second should be (-2,1)

Step-by-step explanation:

You substitute the given value of y into your equation. 6x-y=5

6x-(-6x-5)=5

x=0

y=-6 * 0-5

y=-5

(x,y)=(0,-5)

AND

7x-6(4x+9)=-20

x=-2

y=4x(-2)+9

y=1

(-2,1)

hope this helps!

"Bill’s nominal income in 1990 was $1,009 per month. The CPI had a value of 149 in 1990 and had a value of 192 in 2017. What is
Bas_tet [7]

Answer:

$677.18

Step-by-step explanation:

Data provided in the question:

Bill’s nominal income in 1990 = $1,009 per month

CPI value in the year 1990 = 149

CPI value in the year 2017 = 192

Now,

The Consumer price index ( CPI ) is given as :

CPI = \frac{\textup{Cost of basket in the current year}}{\textup{Cost of basket in the base year}}\times100

thus,

for the given case of year 1990

149 = \frac{\textup{1,009}}{\textup{Real income in the year 1990}}\times100

or

Real income in 1990 = \frac{\textup{1,009}}{\textup{149}}\times100

or

Real income in 1990 = $677.18

insens350 [35]

Answer:

It is the one on the bottom right

Step-by-step explanation:

First of all, we have to start at (0,0), so we can cross out the one on the top left and top right, as they does not.

Also, the one on the bottom right does not go back to the ground, though just stays in the air, but the one on the bottom right dows go back to the ground.

So, its the one on the bottom right

Answer:

V = 43323 mm³

(second answer is already correct)

Step-by-step explanation:

these pennies make up the shape of a cylinder, so, we can solve this question by solving for the volume of a cylinder.

the volume of a cylinder can be found with the formula:

V = πr²h

(V = volume ; π = pi ; r = radius ; h = height)

We know the diameter of this cylinder is 19.05 mm. Diameter is two times the length of the radius, (diameter is all the way across, radius is from center to outer / halfway across) meaning that we can find the radius by dividing 19.05 by 2.

diameter = 19.05

radius = 19.05 / 2 = 9.525

so, r = 9.525

we also are given the height of this cylinder, 38 mm

so, h = 38

π = 3.14159 (π is a constant)

plugging our measurements into the volume formula:

 V = πr²h

V = (3.14159)(9.525²)(38)

V =  (3.14159)(362.9025)(38)

V = 43323.4894628

[rounded to V = 43323 mm³]

And yes, the volume is not affected by a change in shape. (you are correct)

hope this helps!!
