-3x+2y=-39 and 5x+4y=21 Algebra elimination
The solution of the system of equations is x = 9 and y = -6.
What is the system of equations?One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
We have a system of equations,
-3x+2y = -39 {equation 1}
and 5x+4y = 21 {equation 2}
To eliminate the variable y:
Multiply by 2 to the equation 1 and subtract to the equation 2,
5x + 6x + 4y - 4y = 99
11x = 99
x = 9
And y =-6
Therefore, the solution is x = 9 and y = -6.

- Which expression is equivalent to 2(3x + 4)(x - 1)(x-3)? *
Answer: 6x^3−16x^2−14x+24 is your answer
have a good day
Yours,
Nathaniel
Step-by-step explanation:
The expression 2(3x + 4)(x - 1)(x-3) is equivalent to the expression 6x³ - 16x² - 14x + 24 option (A) is correct.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
It is given that:
The expression is:
= 2(3x + 4)(x - 1)(x-3)
After the multiplication of the polynomial:
= 2(3x² + x - 4)(x - 3)
Again multiplication:
= 2(3x³ - 8x² - 7x + 12)
= 6x³ - 16x² - 14x + 24
Thus, the expression 2(3x + 4)(x - 1)(x-3) is equivalent to the expression 6x³ - 16x² - 14x + 24 option (A) is correct.

Step-by-step explanation:
To find Y
divide both sides with -3
-3y=-2x+12/:-3
y=2/3x-4
to find x
2x=3y+12
divide both sides with 2
2x=3y+12/:2

Find all real square roots of 25
Answer:
All real square roots of 25 is +5 and -5.
Step-by-step explanation:
When you square root something, you take the positive and negative of the number, so the square root of 25 would be 5 and -5.
When you do 5 times 5, you get 25 and when you do -5 times -5, you get 25 as well, this is why we do the negative as well.
#teamtrees #WAP (Water And Plant)
It is found that all the real square roots of 25 are 5 and -5.
How to find the closest integer less than and greater than the square root of a number?The function is strictly increasing function for x ≥ 0.
Assuming that all the values of x are ≥ 1, whenever there is increment in the value of 'x', the value of y increases too Perfect square are those integers whose square root is an integer. Let x-a be the closest perfect square less than x, and let x+b be the closest perfect square more than x, then we get: x-a < x < x+b (no perfect square in between x-a and x+b, except possibly x itself).
When we do square root of something, we take the positive and negative of the number, so the square root of 25 would be 5 and -5.
When we do 5 times 5, we will get 25 and when we do -5 times -5, we will get 25 as well, this is why we do the negative as well.
Hence, all the real square roots of 25 are 5 and -5.

Pre-cal Problem, please, help is very much appreciated!
Let y be the length of the third side. By the Pythagorean theorem,
y² + x² = 3² = 9
so that
y = √(9 - x²)
(taking the positive root because one expects length to be positive)
Then by the definitions of sine, cosine, and tangent, we have
sin(θ) = x / 3 → θ = sin⁻¹(x / 3)
cos(θ) = √(9 - x²) / 3 → θ = cos⁻¹(√(9 - x²) / 3)
tan(θ) = x / √(9 - x²) → θ = tan⁻¹(x / √(9 - x²))
Twenty students went to a fast food restaurant. Everyone ordered a hamburger and a drink. Hamburgers cost $3.25 each and drinks cost $1.15 each. How much did the students spend in all?
Answer:
The total amount spent was $88.

The information provided is:
Twenty students went to a fast food restaurant. Everyone ordered a hamburger and a drink. Hamburgers cost $3.25 each and drinks cost $1.15 each.Compute the total cost as follows:
[tex]\text{Total Cost}=\$3.25\cdot \text{No. of Hamburgers}+\$1.15\cdot \text{No. of Drinks}[/tex]
[tex]=(\$3.25 \times 20)+(\$1.15 \times 20)\\\\=\$65+\$23\\\\=\$88[/tex]

70% of Ms. Miller's class passed the test on the first try. Those who failed were able to retake and half of those students passed on their second try. If there are 20 students in the class, what overall percentage passed the test?
Answer:
85%
Step-by-step explanation:
Calculate how many students passed on their first try. 20 x 70% is 14, so 14 students passed on their first try. 6 students retook the test. Half of 6 is 3. Add 3 to the 14 students that passed earlier.Calculate the percent with the equation 17/20 = 0.85. 0.85 = 85%.
