Answers
Answer and Step-by-step explanation:
Alot of these can be solved with the table up above the problems.
A, B, and C.
According to the table, every time a value has an exponent of 0, it would equal to 1. Since all A B and C values follow the 0 exponent, their value is 1.
D.
According to the table, when we have a negative exponent, the number gets turned into a fraction of [tex]\frac{1}{x^x}[/tex]
Since our value is 9^-2, do as followed :
[tex]\frac{1}{9^2}[/tex]
Solve what is 9^2 :
[tex][\frac{1}{81} ][/tex]
E.[tex]\frac{1}{x^{-5} }[/tex]
This question is different, since we have to go backwards, we have to switch the negative exponent to a positive exponent and rid the fraction.
[tex]x^5[/tex]
F.[tex]5a^3b^{-2}[/tex]
Since we have one negative exponent, follow the fraction rule but instead of having one as the numerator, have 5a^3.
[tex]\frac{5a^3}{b^{2}}[/tex]
Fill in the table :[tex]-3^4 = -3*-3*-3*-3=-81[/tex]
Since -3 is in parenthesis, we can rid the negative along with the parenthesis :
[tex](-3)^4=3^4=3*3*3=81[/tex]
Follow the negative exponent rule :
[tex](-3)^{-4}=\frac{1}{(-3)^4} =\frac{1}{3^4} =\frac{1}{3*3*3*3}= \frac{1}{81}[/tex]
Follow the negative exponent rule yet again :
[tex]-3^{-4}=-\frac{1}{3^4} =-\frac{1}{3*3*3*3} =-\frac{1}{81}[/tex]

Solutions of 3x+2y=4 and 6x+4y=8
please tell me how many solutions there are , I will mark you brainiest!!!!
Answers
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.
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

What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
The given equation is 24p + 12 - 18p = 10+ 2p - 6.
(24p-18p)+12=(10-6)+2p
6p+12=4+2p
6p-2p=4-12
4p=-8
p=-2
Therefore, option B is the correct answer.

URGENT will give brilliant mark For the reaction 2Na + Cl2 ------ 2NaCl, how many grams of sodium chloride can be produced from 500g of chlorine? ( atomic masses : Na = 23 , Cl = 35.5 g/mol) *
1 point
112 g
319 g
409 g
825 g
Answers
Answer:
825 g
Step-by-step explanation:
Here's my work:
500g Cl2 l 1mol Cl2 l 2 mol NaCl l 58.5 g NaCl
l 71 g Cl2 l 1 mol Cl2 l 1 mol NaCl
= 823.94 - the rounding can be a little off
The first thing you have to do is convert the 500 g of Cl2 into moles. So you get the mass of Cl which is 35.5, but Cl is diatomic by itself so you multiply 35.5 x 2 and get 71. now on the third column you are comparing the mol ratios of the equation. The equation is 2Na + Cl2 ---> 2NaCl, so you see that there is no coefficient in front of Cl2 so that means there is 1 mol, and then you see that in the product there is a coefficient of 2 in front of NaCl so that means there is 2 moles. Then finally you have to convert the moles backs into grams where you just add the masses of Na and Cl . You multiply across the top and then divide that number by the bottom row.

Kiran is about to start hiking on a trail that is 1.8 miles long. In his past hikes on the same trail, he had walked at a constant rate of 2.4 miles an hour, which is 0.04 mile a minute. Function (F) represents Kiran's remaining distance on the trail, in miles, t, minutes after he starts walking. Write an equation to represent this function. Use function notation.
Answers
Answer:
F(t) = 1.8 - 0.04t
Step-by-step explanation:
Given that :
Length of trail = 1.8m
Walking speed = 0.04 miles per minute
Distance left, t minutes after one statues walking :
Total distance covered after t minutes = speed * time = 0.04t
Distance left after t minutes :
Initial distance - distance covered
Hence,
F(t) = 1.8 - 0.04t
