Step 2: Remove the opposites.

2x - 4y = -1

Answer = 2x - 4y = -1

Step-by-step explanation:

Answer: the answer is d/f+3

sorry i couldnt find my work for this problem but i hope it helps !

An equation is formed of two equal expressions. When in the given equation the value fo b is d/(f+3).

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

fb + 3b = d

Take b as a common term from both the terms on the left side of the equation,

b(f + 3) = d

Divide both the sides of the equation by (f+3),

b(f + 3)/(f+3) = d/(f+3)

Simplify,

b = d/(f+3)

Hence, when in the given equation the value fo b is d/(f+3).

Distance = 5 km

Answer:

y = (2/3)x - 1

Step-by-step explanation:

By refering the graph, we can see that y-intercept(b) = (a point of the y-axis) which is -1.

the coordiates i have taken:

(-3 , -3) ------ (-3 =x1, -3 =y1)

and

( 3, 1 ) --------( 3 = x2, 1 = y2)

To find slope,

slope(m) = rise/run = ( y2 - y1 ) / ( x1 - x2 )

=> ( 1 - (-3) ) / ( 3 - (-3) ) -----( negative × negative = positive. Hence the signs are positive. )

=> ( 1 + 3 ) / ( 3 + 3 )

=> 4 / 6

=> 2 / 3 ------(simplied after numerator and denominator got divided by 2)

now,

b = -1

m = 2/3

x = x ----(x remains same)

Therefore,

y=> mx + b

by substituting the values, we get,

y=> (2/3)x - 1

Answer:the answer is b :)

Answer:

k = 28/7 which equals 4

Step-by-step explanation:

1/2k + 6 = 4k - 8

1/2k - 4k = -8 - 6

1/2k - 8/2k = -14

-7/2k = -14

k = -14 * - 2/7

k = 28/7 which equals 4

Step-by-step explanation:

4.67e-8 is rewritten as 4.67 x 10^-8.

Negative -> decimal with lots of places, Positive -> big, big number

Move the decimal place right 8 times so you end up with a small decimal.

Answer:

$606

Step-by-step explanation:

For the first 40 hours, she was making $12. With this, we can do 12x40, which is 480$. We can store that in a safe space for later access. Afterwards, since the problem says that "after 40 hours she earns time and a half for her work" we can assume she gets 1.5x her pay after 40 hours, which is $18 (We can get this by 12 / 2 = 6. Then do 12 + 6 = 18). Then we can do 18x7 because she worked 7 hours over 40. With that, we get 126$. Now we can do 480$ + 126$ = 606$. So, she earned 606$.

Transversal line

That is a picture of a Transversal line, a Transversal line intersects 2 or more parallel lines.

========================================================

Explanation:

Consider a triangle with side lengths a,b,c such that a < b < c

a = 3 and b = 19 are the two known sides

Let c be the missing side length

The missing side has the property that...

b-a < c < b+a

19-3 < c < 19+3

16 < c < 22

Meaning that if c is a whole number then it can take on any of these values {17, 18, 19, 20, 21}

So c = 21 is the largest possible third side, where only whole number sides are considered.

We can't have a third side of 22 because the two other sides add to a+b = 3+19 = 22 and a triangle wouldn't form (instead only a straight line would). I recommend cutting out strings of paper trying this out yourself.

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

Side note: The inequality b-a < c < b+a is a variation of the triangle inequality theorem.

Given :

The equation below can be used to determine I (simple interest) on a loan as follows :

[tex]I=Prt[/tex] ...(1)

P is principal, r the rate of the loan,  t is the length of the loan in years.

We need to find the equation to solve in terms of r. We can find the value of P.

Dividing both sides of equation (1) by rt. So,

[tex]\dfrac{I}{rt}=\dfrac{Prt}{rt}\\\\P=\dfrac{I}{rt}[/tex]

So, P can be solved as : [tex]P=\dfrac{I}{rt}[/tex].

Answer:

4.5 in. is equivalent to 337.5 ft.

Step-by-step explanation:

The given parameters are;

The scale of the scale map is 2 in. to 150 ft.

The measured length on the scale map = 4.5 inches

The actual distance of the location is given as follows;

2 in. is equivalent to 150 ft.

Therefore;

1 in. is equivalent to 150 ft./2 = 75 ft.

4.5 in. will be equivalent to 4.5 × 75 ft. = 337.5 ft.

4.5 in. will be equivalent to 337.5 ft.

Answer: 34.78 gallon

Step-by-step explanation:

Exponential equation for decay:

[tex]A=P(1-r)^t[/tex] , where p = initial amount, r= rate of decay , t= taime

As per given,

r= 8% = 0.08

For days 1 , i.e. at t= 0 , P= 32 gallons

[tex]1=32(1-0.08)^t\\\\\Rightarrow\ \dfrac{1}{32}=(1-0.08)^t \\\\\Rightarrow\ \ln \left(\frac{1}{32}\right)=t\log (0.92)\\\\\Rightarrow\ t=-\frac{5\ln \left(2\right)}{\ln \left(0.92\right)}=41.5\approx42[/tex]

Total water = [tex]\dfrac{a(1-r^n)}{1-r}=\dfrac{32(1-0.08^{42})}{1-0.08}=34.782[/tex]

hence, the the total number of gallons of water that leaked from the tank = 34.78 gallon approx.
