For the following system,

3x + y = 8
−x − 2y = −10

if you isolated x in the second equation to use the substitution method, what expression would you substitute into the first equation?
−2y + 10
2y + 10
2y − 10
−2y − 10

Answers

Answer 1

Answer:

-2y+10

Step-by-step explanation:

-x - 2y = -10

add 2y to both sides

-x = -10 + 2y OR 2y - 10

divide both sides by -1

x = -2y+10

The citizenship clause of the Fourteenth Amendment is important because it was the first time the Constitution defined what a citizen is.

What is a clause?

A section, phrase, paragraph, or segment of a legal document, such as a contract, deed, will, or constitution, that relates to a particular point.

The Fourteenth Amendment :-

All persons born or naturalized in the United States and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside.

No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty or property, without due process of law, nor deny to any person within its jurisdiction the equal protection of the laws.

Hence, the correct statement is :- it was the first time the Constitution defined what a citizen is.

Find the surface area of this cylinder using pie.

Answers

Answer:

Thus, the surface area of a cylinder involving pie is:

[tex]\:\:\:A=36\pi \:[/tex] in²

or

[tex]A\approx 113.1[/tex] in²

Step-by-step explanation:

Given

radius = r = 2 in height = h = 7 in

Using the formula to determine the surface area of a cylinder:

[tex]A=2\pi \:rh+2\pi \:r^2[/tex]

[tex]A=\left(2\times \pi \times \:2\times 7\right)+\left(2\times \pi \times \:2^2\right)\:[/tex]

write an equation in slope-intercept form of the line that passes through the given points (-4,-2) (8,-2)

Answers

Answer:

y=-2

Step-by-step explanation:

First, find the slope using the slope formula: m=y2-y1/x2-x1

Plug the numbers into the equation and get 0

Using the slope and one of the coordinates, put the equation into point-slope form: y-y1=m(x-x2)

y+2=0(x+4)

Distribute and simplify to get the final answer.

y+2=0+0

y=-2

So you would graph the two points to make the line, then find the slope by doing rise/run. The slope equation is y=mx +b and m is slope so u would plug that in. Then you would find the y-int / b by finding the point on the line where it crosses the y acis/ when x is zero! There u hv it!
