Solutions of 3x+2y=4 and 6x+4y=8

please tell me how many solutions there are , I will mark you brainiest!!!!

Answers

Answer 1

Answer:

Infinite solutions

Step-by-step explanation:

1) First, you can solve this easily by elimination. Multiply the first equation by -2 in order to cancel out terms when adding to the second equation.

2) Then, add the new set of equations together. However, everything cancels out, bringing us to 0 = 0. This means that the lines the equations make must be the same. Thus, all real numbers must make this equation true, meaning that there are infinite solutions.

Solutions Of 3x+2y=4 And 6x+4y=8please Tell Me How Many Solutions There Are , I Will Mark You Brainiest!!!!
Answer 2

Step-by-step explanation:

3x + 2y = 4

2y = -3x +4

y = -3/2x +2

6x+4y = 8

4y = -6x +8

y = -6/4x + 8

y = -3/2x + 8

same slope, bit different intercepts. they are parallel. no solutions

A textbook store sold a combined total of 228 biology and physics textbooks in a week. The number of blology textbooks sold was three times the number of
physics textbooks sold. How many textbooks of each type were sold?

Answers

Step-by-step explanation:

Let us assume p is the number of psychology books and b is the number of biology textbooks.

set up first equation:

we know that the total number of books sold was 393

p+b=393

set up second equation:

we know that there were 79 less biology book sold that psychology so...

p = b + 79

subsitute p in the first equation to solve for b

solve value for p

Answer:

15 1/6

Step-by-step explanation:

change -8 2/3 into an improper fraction = -26/3

-4/7v = -26/3

cross-multiply:

3(-4v) = (-26)7

-12v = -182

v = 182/12

v = 15 1/6

At a concert the ratio of men to women is 5:3
The ratio of women to children is 7:4
Show that more than half of the people at the concert are men.

Answers

Men: 5 : 3 = 20 : 12
Women: 7 : 4 = 21 : 12

So for every 12 children there are 20 men to 21 women.

Neither men nor women compose more than half of the concert population.

If the base angles of a triangle are congruent, use the Law of Sines to show the triangle is isosceles.

Answers

Answer:

The Isosceles Triangle Theorem States that if a triangle contains 2 congruent sides, then the angles opposite those sides are congruent. This theorem can be proved using the Law of Sines: The Law of Sines states that: asinA=bsinB=csinC If a=c, making △ABC an isosceles triangle, then asinA=asinC!

The law of sins says: a/SinA = b/SinB = c/sinC

For this to be an isosceles triangle then side a must equal side c

so then a/sinA = c/sinC

Then you can divide both sides by a and raise to the power of -1 and you would get angle A = angle C which makes this isosceles.

In your own words, what is a radical expression?

Answers

Answer:

In mathematics, a radical expression is defined as any expression containing a radical (√) symbol. Many people mistakenly call this a 'square root' symbol, and many times it is used to determine the square root of a number. However, it can also be used to describe a cube root, a fourth root, or higher. When the radical symbol is used to denote any root other than a square root, there will be a superscript number in the 'V'-shaped part of the symbol. For example, 3√(8) means to find the cube root of 8. If there is no superscript number, the radical expression is calling for the square root.

The term underneath the radical symbol is called the radicand.

Cosx=4/5 what is sin2x cos2x and tan2x

Answers

Answer:

-24/5

Step-by-step explanation:

The solution to the problem is as follows:

cscx < 0 means 1/sinx < 0, or sinx < 0.  

sinx = -3/5 because you're dealing with a 3-4-5 triangle, and we established

sinx is negative.  

sin2x = 2sinxcosx = 2*-3/5*4/5 = -24/25  

cos(2x) = cos^2(x) - sin^2(x) = 16/25 - 9/25 = 5/25 = 1/5  

tan2x = sin2x / cos2x = -24/5
