What is the value of x in the solution to this system of equations
Y+2x=-1 y=1/2x+4

Answers

Answer:

x=-25/2, y=-9/4. (-25/2, -9/4).

Step-by-step explanation:

The solution of the given system of linear equation will be x = -2 and y = 3.

What is linear equation?

A linear equation is an algebraic equation in which each term has an exponent of 1 and, when graphed, the result is always a straight line.

Given are the equations,

y+2x=-1 ⇒ y = -1-2x

y=1/2x+4

Equating the equation,

-1-2x = 1/2x+4

x+8 = -2-4x

5x = -10

x = -2

And, y = -1+4

y = 3

Hence, the value of x and y are -2 and 3 respectively.

Find the area of the isosceles triangle. please help thanks

Answers

Answer:

1080 m^2 Don't submit m^2 in your answer.

Step-by-step explanation:

Givens

The catch is to find h

To do that, use a^2 + b^2 = c^2

a b and c are in the same 1/2 triangle.

a = 48/2 = 24 m

b = h = ?

c = 51 meters

Solution

a^2 + b^2 = 51^2                      Substitute for b^2 = h^2

24^2 + h^2 = 51^2                   Expand 24^2 and 51^2

576 + h^2 = 2601                    Subtract 576 from both sides

h^2 = 2601 - 576

h^2 = 2025                              Take the square root of both sides

h = 45

Area

Area = 1/2 b * h

Area = 1/2 48 * 45

Area = 1080

Remark

Notice that to find h you only use 1/2 of 48 because that is the base of the right triangle.

To find the area, you need to use all of 48 because 48 is the full length of the base.

what is the scale factor

Answers

Answer:

2/5

Step-by-step explanation:

Since it's from a big square to a smaller square, the smaller number will be at the top. Also, use the same side to find the scale factor, but since this is a square and all sides of a square are equal, it doesn't matter but in other shapes it does so practice i guess:

Left side of big square: 5

Left side of small square: 2

So scale is 2/5

To confirm:

5 · 2/5 = 10/5 = 2, we're right

A scale factor is usually a decimal which scales, or multiplies, some quantity. In the equation y = Cx, C is the scale factor for x. C is also the coefficient of x, and may be called the constant of proportionality of y to x.

______________________________

1.) Subtract 60 from both sides:[tex]60-60=[/tex] Cancels Out.[tex]240-60=180[/tex].

 - We subtract on both sides to get rid of the extra numbers, so at the end of the equation we'll be able to get x alone. To do so you have to do the opposite of what you see.

Equation at the end of Step 1:

[tex]15x[/tex] < [tex]180[/tex]

2.) Divide both sides by 15:[tex]180[/tex] ÷ [tex]15=12[/tex][tex]15x[/tex] ÷ [tex]15=x[/tex]

 - Since 15 is positive, the inequality direction remains the same.

Equation at the end of Step 2:

Maurice and his father are building a dog house. They are using long pieces of wood and cutting them into smaller pieces. They have a piece of wood that is 3.6 feet long and are cutting it into pieces that are each 0.75 feet. How many smaller pieces will they be able to make?

Answers

Answer:

4.8 smaller pieces

Step-by-step explanation:

Total length of wood = 3.6 feet

Length of each piece = 0.75 feet

How many smaller pieces will they be able to make?

Number of smaller pieces of wood = Total length of wood / Length of each piece

= 3.6 feet / 0.75 feet

= 4.8 smaller pieces

Number of smaller pieces of wood = 4.8
