How many solutions does the following system of equations have?
{4x + 6y = 24
2x + 3y = 12
Answer:
Infinitely many solutions
Step-by-step explanation:
Note that 2(2x+3y=12) is 4x+6y=24, which is the first equation. Therefore, by canceling the equations out, you have 0=0, which means whatever one side equals, the other side ALWAYS equals that.

[tex]\sqrt{x^{2}-16 }-3\sqrt{x-4}=0[/tex]
Answer:
[tex]\tt{} x_{1} = 4 \\ \tt{} x_{2} = 5 \\ [/tex]
Step-by-step explanation:
[tex]\tt{} \sqrt{ {x}^{2} - 16 } - 3 \sqrt{x - 4} = 0[/tex]
[tex]\tt{} \sqrt{ {x}^{2} - 16 } = 3 \sqrt{x - 4} [/tex]
[tex]\tt{}{x}^{2} - 16 = 9(x - 4)[/tex]
[tex]\tt{}(x - 4).(x + 4) = 9(x - 4)[/tex]
[tex]\tt{}(x - 4) \times (x + 4 - 9) = 0[/tex]
[tex]\tt{}( x - 4) \times (x - 5) = 0[/tex]
[tex]\tt{}x - 4 = 0 \\ \tt{}x - 5 = 0[/tex]
[tex]\tt{}x = 4 \\ \tt{}x = 5 \\ \\ [/tex]
[tex]\tt{} x_{1} = 4 \\ \tt{} x_{2} = 5 [/tex]
Answer:
x = 4, 5.
Step-by-step explanation:
√(x^2 - 16) - 3√(x - 4) = 0
√(x^2 - 16) = 3√(x - 4)
Square both sides of the equation:
x^2 - 16 = 9(x - 4)
x^2 - 9x - 16 + 36 = 0
x^2 - 9x + 20 = 0
(x - 4)(x - 5) = 0
x = 4, 5.
As the original equation contained square roots:
We test for extraneous solutions:
x = 4:
√(4^2 - 16) - 3√(4 - 4) = 0 - 3*0 = 0 so x = 4 is OK.
x = 5:
√(5^2 - 16) - 3√(5 - 4) = √9 - 3√1 = 0 so x = 5 is also OK.

2 1/3 + 3 1/4 as a fraction
Answer:
67/12 (just in case if they would ask you for the simplified form the answer in is 5 7/12)Step-by-step explanation:
convert both mixed fractions to improper fractions first
2 1/3 = 7/3 3 1/4 = 13/4
(cross multiplication method, to make both fractions have the same denominator)
7/3 + 13/4
7/3 × 4/4 = 28/12
13/4 × 3/3 = 39/12
28/12 + 39/12 = 67/12 (just add, denominator will remain the same)
67/12 (simplify)
67/12 = 5 7/12 (simplified)

Brainliet ko maka sagot
Answer:
first multiply 3 with −8 and we get − 24
then find two numbers that if we add or subtract we get + 10 and if we multiply we get − 24
and the numbers are + 12 and −2
then we place those numbers as follow :-
3x²+12x−2x−8
then we group them
(3x2+12x)(−2x−8)
now take the common factor out.
3x(x+4)−2(x+4)
then group the numbers outside of the brackets
(3x−2)(x+4)
And that is the answer:
Proper Solution:-
1.) 3x2+10x−8
2.) 3x2+12x−2x−8
3.) (3x2+12x)(−2x−8)
4.) 3x(x+4)−2(x+4)
5.) (3x−2)(x+4)
A pet store has 15 birds and 75 fish.
In simplest form, what is the ratio of birds to fish in the pet store?
O1/6
O1/5
O5/1
I don't know
Answer:
1/5
Step-by-step explanation:
For every bird in the store there will be 5 fish.
Because there is 5 times more fish then birds.
Using the ratio concept, the number of birds to fish expressed as a ratio is 1/5
Given the Parameters :
Number of birds = 15 Number of fishes = 75Ratio of the number of birds to fish can be expressed thus :
Number of birds : Number of fishes15 : 75
Divide both sides by 15
1 : 5
Hence, the ratio of birds to fish is 1/5
