Which of the following equations is not a linear equation?
(LOOK AT PHOTO!!!)
Answer:
I think that B is not a linear equation.
Step-by-step explanation:
Linear eqautions can not contain exponents in them. B has x to the power of 3 and y to the power of 2, ruling it out to be a linear equation.
I hope this helps! :)
[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]
Linear equation has a degree of 1, that means the maximum power of a variable in a linear equation/expression should be 1. if an equation doesn't satisfy this condition then it's not a linear equation.
So, by Observing the choices, we get to the conclusion that the one which isn't a linear equation is B
[tex]\qquad \sf \dashrightarrow \: {x}^{3} - 5 {y}^{2} = 4[/tex]
Here, the variables have greater powers tham one, and degree is 3. so it's the required Answer ~

Answer:
56 degrees
Step-by-step explanation:
The total amount of degrees in a triangle is 180: all three angles add up to 180. We can set up an equation to solve this.
40 + 2x + 3x = 180
Let's add like terms:
40 + 5x = 180
Subtract 40 on both sides:
5x = 140
Divide by 5 on both sides to solve for x:
x = 28
Angle A is equal to 2x. Plug in 28 for x. 2*28 = 56. Therefore, Angle A is 56 degrees.
Answer:
∠ A = 56°
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
2x + 3x + 40 = 180
5x + 40 = 180 ( subtract 40 from both sides )
5x = 140 ( divide both sides by 5 )
x = 28
then
∠ A = 2x = 2(28) = 56°
SBC is an isosceles triangle with main vertex S.
→ Let D be the symmetric of B with respect to C and A the symmetric of C with respect to B.
1) Compare AB and CD
2) Compare the angles SBA et SCD.
3) Deduce that the triangles SBA and SCD are congruent.
4) What is the nature of the SAD triangle?
Help me if u help me u get points I’m poor help me I don’t have much time :(
Answer + Step-by-step explanation:
1) D be the symmetric of B with respect to C then CD = BC
A the symmetric of C with respect to B then AB = BC
We obtain :
CD = BC
AB = BC
Then AB = CD
2) m∠SBA = 180 - SBC = 180 - SCB = m∠SCD
3) we have :
BA = CD
BS = CS
m∠SBA = m∠SCD
Then
the triangles SBA and SCD are congruent
4)
the triangles SBA and SCD are congruent Then SA = SD
Therefore SAD is an isosceles triangle.

309,303,297,... Find the 31st term.
Answer:
129
Step-by-step explanation:
The easiest thing to do would be an equation.
Since the value is decreasing by 6 each time you have -6x
-6x+?=?
Next thing you do, to get the y-intercept, would be to add 6 to the 309, which is the first term in order to get the zeroth term. This would make 315 the y-intercept
-6x+315=?
To solve for the 31st term, plug in 31 for x to get 129

The measure of angle C is 122 degrees.
We have given that,
In triangle ABC, m∠A=23° and m∠B=33°
We have to determine the remaining angle of the triangle.
What is the sum of the angle of the triangle?
The sum of the angles in a triangle is 180 degrees.
Therefore we get
angle A+ angle B+ angle C= 180 degrees
23+33+angle C=180
angle C=180-56
angle C=122
Therefore the measure of angle C is 122 degrees.

The bonds of the products store 27 kJ more energy than the bonds of the reactants. How is energy conserved during this reaction?
A. The reaction system absorbs 27 kJ of energy from the surroundings.
B. The reaction creates 27 kJ of energy when bonds form.
C. The surroundings absorb 27 kJ of energy from the reaction system.
D. The reaction uses up 27 kJ of energy when bonds break.
As per the law of conservation of energy:
C. The reaction system absorbs 22 kJ of energy from the surroundings
Law of conservation of energy:This law of energy states that the energy remains conserved its neither created nor destroyed. It remains conserved throughout the reaction.
when an amount of heat gets absorbed during the reaction from the surroundings this type of reaction is known as an endothermic reaction.
So, for fulfilling law of conservation, same amount of energy must be asborbed.

How many protons, neutrons, and electrons are found in a neutral atom of carbon-13?
Since both are neutral, we know that each has 6 electrons as well. The sum of protons plus neutrons equals the mass number 12 in 12-C, so carbon-12 has 12 – 6 protons = 6 neutrons. The sum of protons plus neutrons equals the mass number 13 in 13-C, so carbon-13 has 13 - 6 protons = 7 neutrons.

Step-by-step explanation:
Tritium is a radioactive isotope of hydrogen that decays by about 5% per year. A large bottle of water that contained 450,000 tritium atoms remained undisturbed for 11 years. How much tritium does the bottle contain now?
If necessary, round your answer to the nearest whole number
Using an exponential function, it is found that the bottle contains 255,960 atoms of tritium after 11 years.
What is an exponential function?A decaying exponential function is modeled by:
[tex]A(t) = A(0)(1 - r)^t[/tex]
In which:
A(0) is the initial value.r is the decay rate, as a decimal.In this problem:
The bottle initially contained 450,000 tritium atoms, hence A(0) = 450000.The amount decays by about 5% per year, hence r = 0.05.Thus, the equation is given by:
[tex]A(t) = A(0)(1 - r)^t[/tex]
[tex]A(t) = 450000(1 - 0.05)^t[/tex]
[tex]A(t) = 450000(0.95)^t[/tex]
After 11 years, the amount is given by:
[tex]A(11) = 450000(0.95)^{11} = 255960[/tex]
The bottle contains 255,960 atoms of tritium after 11 years.
