What is the solution to the following system of linear equations?

Mathematics
1 answer:
djverab [1.8K]3 years ago
7 0

Answer:

There is no solution.

Step-by-step explanation:

4y − 36 = −12x

3x + y = −9

Add 12x and 36 to both sides of the first equation.

12x + 4y = 36

3x + y = -9

Multiply both sides of the second equation by -4.

12x + 4y = 36

-12x - 4y = 36

Add the two equations.

0 = 72

Since 0 = 72 is a false statement, this system of equations has no solution.

Based on the graph, what is the perimeter of an octagon?​
Ghella [55]

Answer:

The perimeter of the regular octagon is 104 units

Step-by-step explanation:

we know that

The segment LM is the length of one side of the octagon

we have the coordinates

L(-6,-2) and M(6,3)

step 1

Find the distance LM

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

substitute the values

d_L_M=\sqrt{(3+2)^{2}+(6+6)^{2}}

d_L_M=\sqrt{(5)^{2}+(12)^{2}}

d_L_M=\sqrt{169}

d_L_M=13\ units

step 2

Find the perimeter

we know that

A regular octagon has eight equal sides

so

To find out the perimeter, multiply by 8 the length of the segment LM

P=8(13)=104\ units

Leila says that 75% of a number will always be greater than 50% of any other number.
Gemiola [76]
That is not correct, it depends on the numbers you are referring to. For instance, 75% of 100 is 75, but 50% of 1000 is 500, so in this case the 50% of a number is higher than 75% of another number. Although, is true that 75% is higher than 50% of the same number always.

Express V in terms of T
Lorico [155]

Answer:

v = \frac{4t-1}{3}

Step-by-step explanation:

Given

t = \frac{3v+1}{4} ( multiply both sides by 4 to clear the fraction )

4t = 3v + 1 ( subtract 1 from both sides )

4t - 1 = 3v ( divide both sides by 3 )

\frac{4t-1}{3} = v
