Answer 1

Answer:

y=2x-3

Step-by-step explanation:

y=mx+c

m=gradient=

5-(-5)/4-(-1)

=10/5

=2

c=y intercept=-3

y=2x-3

Answer 2

Answer:

y = 2x - 3

Step-by-step explanation:

(4, 5) and (0, -3)

m=(y2-y1)/(x2-x1)

m=(-3-5)/(0-4)

m=(-8)/(-4)

m=2

y - y1 = m(x - x1)

y - 5 = 2(x - 4)

y - 5 = 2x - 8

y = 2x - 3

A school is planning to construct two rectangular play areas in the playground.
The length of play area A must be 1 foot longer than four times its width. The width of play area B must be 2 feet longer than the width of play
area A, and the length must be 2 feet longer than three times its own width. In
addition, the areas of the two play areas must be equal.
Write a system of equations to represent this situation, where y is the area of the play areas and x is the width of play area A. Which statement
describes the number and viability of the system's solutions?
ОА.
The system has two solutions, but only one is viable because the other results in a negative width.
B.
The system has only one solution, and it is viable because it results in a positive width.
c. The system has two solutions, and both are viable because they result in positive widths.
d. The system has only one solution, but it is not viable because it results in a negative width.

Step-by-step explanation:

If we're trying to find an area of a rectangle, we're going to use the following formula:

a=l×w

A being our answer, area, l being length, our 19km, and w, being our width, our 10km.

We multiply 19 and 10 and get the result 190km!

hellllp pllzzzzzzzz plzzzz i want to learn how to solve it​

Answers

Answer:

The answer would be : F.

Step-by-step explanation:

for this you should on look at the x axis line.

The left side is the negative side and the right side is the positive side.

As you can see the line from the circle on the negative side of the x axis is going to the positive side.

Meaning that X will be greater than -9

Thus we have this part of the answer so far

-9<x

(Before we proceed remember if the circle is not colored in that means it is either greater than or less then. So you would use these </>. But if it is colored in then it is either less than or equal to OR greater than or equal to. I don't have the symbols on my phone keyboard but they are just "<" or ">" with a line under them.)

The next point on the positive/right side is colored in and going towards the negative/left side therefore, X will be less than or equal to 2.

(2 being where the point is on the x axis line)

so we will get : -9 < x (less than or equal to sign) 2

What will happen to a number, if it was added to its inverse?

Answers

Answer:

The word "inverse" in the question is ambiguous, since x usually has inverses under both addition and multiplication. ... If the question is asking about the additive inverse (opposite), then the sum is always 0 for any x . So the sum takes its maximum value for any x .

Step-by-step explanation:

Answer:

Zero

Step-by-step explananation:

An inverse is the opposite of another number, so if you add them together it would equal zero.

Here are a few examples.

5+-5=0

9+-9=0

150+-150=0

-220+220=0

-476+476=0

The inverse is simply the originall number, but on the opposite side of the number line. Meaning you add or take away the negative sign, depending on the original number.

Hope I explained well:)
