Answer:

2.71

Step-by-step explanation:

Its as simple as plugging in the values of y and z.

THis would give you

      -1.46 + (-3.82) + 7.99

This plus^ you can think about having a 1 in front of it like

-1.46 + 1 (-3.82) +7.99

Multiple positive 1 with -3.82 1 times any value is that number, and positive times negative is negative. then looking like this:

-1.46 - 3.82 + 7.99 plug into a calculator and you get +2.71

Answer:

2.71

Step-by-step explanation:

We'll add the first value and the value in parentheses, being -3.82, then we'll add y, which is a negative because "-y", being -1.46. That becomes -5.28.

We'll then take our -5.28 and add 7.99, which will become 2.71.

Therefore, 2.71 is your answer.

Answer:

Option (E)

Step-by-step explanation:

[tex]\frac{a}{b}=\frac{c}{d}=k[/tex]

[tex]\frac{a}{b}=k[/tex]

[tex]b=\frac{a}{k}[/tex] ------(1)

[tex]\frac{c}{d}=k[/tex]

[tex]d=\frac{c}{k}[/tex] -------(2)

Since, [tex]\frac{6a+24}{md+6b}=k[/tex]

By substituting the values of b and d from equation (1) and (2),

[tex]\frac{6a+24}{\frac{mc}{k}+\frac{6a}{k}}=k[/tex]

[tex]\frac{k(6a+24)}{6a+mc}=k[/tex]

[tex]\frac{6a+24}{6a+mc}=1[/tex]

6a + 24 = 6a + mc

mc = 24

m = [tex]\frac{24}{c}[/tex]

Therefore, Option (E) will be the correct option.

Answer:

Yes it is

Step-by-step explanation:

The equation is proportional since as the value of x is increasing, y is also increasing

Equations can either be direct, inverse, or even joint. For instance, if y is directly proportional to x, this is expressed as:

y = kx

k is the variation constant

For a proportional equation, there an increase in a variable will lead to a decrease or increase in other variables

Given the expression y = 9x + 1/2,

when x = 1

y = 9(1) + 1/2

y = 9.5

when x = 2

y = 9(2) + 1/2

y = 18.5

We can see that the equation is proportional since as the value of x is increasing, y is also increasing

Steps/Reasons/Explanation:

Question: Equations with variables on both sides: decimals and fractions, algebra 2. [tex]0.5s + 1 = 7 + 4.5s[/tex].

Step 1: Subtract [tex]0.5[/tex] from both sides.

[tex]1 = 7 + 4.5s - 0.5s[/tex]

Step 2: Simplify [tex]7 + 4.5s - 0.5s[/tex] to [tex]7 + 4s[/tex].

[tex]1 = 7 + 4s[/tex]

Step 3: Subtract [tex]7[/tex] from both sides.

Answer:

a = 2

b = - 6

c = 0

Step-by-step explanation:

Since, -3,0 and 2 are the zeroes of the polynomial

[tex] Plug \:x = 0\: in \:p(X) \\

\implies p(0)= 0\\

\therefore 0= 0^3 +(a-1)(0)^2 +b(0)+c\\

\therefore 0= 0 +(a-1)\times 0 +b(0)+c\\

\therefore 0= 0 +0+0+c\\

\red{\bold{\therefore 0=c}}.....(1)\\\\

p(X)=x³+(a-1)x²+bx+c. \\

Plug \:x = -3\: in \:p(X) \\

[tex] \implies p(-3)= 0\\

\therefore 0= (-3)^3 +(a-1)(-3)^2 +b(-3)+c\\

\therefore 0= -27 +(a-1)\times 9 +b(-3)+c\\

\therefore 0= - 27 +9a-9 - 3b+c\\

\therefore 0= - 36+9a-3b+c\\

\therefore 36 =9a-3b+c... (2)\\

Plug \:c= 0\: in \:equation \: (2)\\

36= 9a - 3b + 0\\

36= 9a - 3b\\

36= 3(3a - b) \\

\purple {\bold{12 = 3a - b}} .... (3)\\\\

Plug \:x = 2\: in \:p(X) \\

\implies p(2)= 0\\

\therefore 0= 2^3 +(a-1)(2)^2 +b(2)+c\\

\therefore 0= 8 +(a-1)\times 4 +b(2)+c\\

\therefore 0= 8 +4a-4+2b+c\\

\therefore 0= 4 +4a+2b+c\\

\therefore - 4=4a+2b+c.....(4)\\

Plug \:c= 0\: in \:equation \: (4)\\

- 4 = 4a +2b+0\\

-4= 2(2a+b)\\

\orange{\bold{-2=2a + b}} .......(5)\\\\[/tex]

Adding equation (3) and (5), we find:

12 = 3a - b

-2 = 2a + b

_________

10 = 5a

10/5 = a

a = 2

Plug a = 2 in equation (5)

-2= 2(2) + b

-2 = 4 + b

-2 - 4 = b

-6 = b

b = - 6

Answer:

36

Step-by-step explanation:

I don’t know if this half the problem or something because you only need to know what a equals but...

1. Substitute x for 4 since x=4... so the equation would then be (4)^2+10(4)-20

2. You simplify so 4 squared is 16 because when you square something you times it by it self so 4^2 is simply 16 because 4*4=16 then 10*4 is 40 so then you get 16+40-20

3. So you can simplify that again to 56-20 and then to 36

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the amount of the school supply kit be A

The value of A is $ 25

The percentage discount of the school supply kit = 20 %

So , the value of the percentage amount is given by the equation

The cost of the school supply kit after discount = ( amount of the school supply kit - ( percentage discount of the school supply kit x amount of the school supply kit ) )

Substituting the values in the equation , we get

The cost of the school supply kit after discount = 25 - ( 20/100 x 25 )

The cost of the school supply kit after discount = 25 - ( 25 x 0.2 )

The cost of the school supply kit after discount = 25 - 5

The cost of the school supply kit after discount = $ 20

Therefore , the discounted price is $ 20

Hence ,

The amount of the school supply kit after the discounted price is $ 20

Answer:

sir the picture is black

Step-by-step explanation:

Answer:

If an atom has the same number of protons and electrons then it is electrically neutral. Not all atoms have to have the same number of atoms because the number of electrons can be changed with the element remaining the same. Protons have a positive charge while electrons have a negative charge. The net charge is dependent on the number of protons and electrons. If it has more protons it would have a higher amount of positive charge therefore making it a positive net charge. The same thing applies with electrons just opposite.

If the atom has no charge (neutral) then there are the same number of protons and electrons. The positive protons cancel out with the negative electrons to produce this neutral state. We can say the net charge is 0 here.

Now if you take away one or more electrons, then there will be more positive protons to outnumber the negative electrons. Overall, the net charge will be positive. For example, if the atom loses 3 electrons, then you'll have a net charge of [tex]3^{+}[/tex]. These positively charged ions are known as cations. You pronounce this as "cat-ion" instead of "catshun".

On the flip side, if you add electrons to an atom, then you'll make the net charge overall to be negative. So let's say we add 4 electrons. We'll have the net charge be [tex]4^{-}[/tex] and this is an anion. To pronounce "anion" you would say "an ion" instead of "anyun".

---------------

In short, the number of protons and electrons are the same if the net charge is 0 and we're not dealing with ions. If you are dealing with ions, then the two counts will not be the same. Note how in the examples above, I didn't change the number of protons. Doing so would change the overall element entirely.

Answer:

- 8° per hour

Step-by-step explanation:

Given that:

Station A = - 6°

Station B = 2°

Rate of temperature change = x° / hour ; which is the same at both stations

Temperature at station A 3 hours after the recording is the same as the temperature in station B 4 hours after the recording ;

Temperature change in Station A:

-6 + 3x

Temperature change in station B:

2 + 4x

Temperature change in A = temperature change in B

-6 + 3x = 2 + 4x

Collect like terms

3x - 4x = 2 + 6

- x = 8

x = - 8

Hence, the rate of temperature change x in both stations is - 8° per hour
