Answer:

Both of them work

Step-by-step explanation:

by multiplying the first equation by 2 it creates the same coefficient in front of "p" for both equations. same for the second equation and "q".

Both strategies works since we can easily eliminate a variable from both equations.

Given the simultaneous equation solved by Tyler

4p + 2q = 62

8p - q = 59

In order for him to eliminate a variable to solve the system of equations, he must ensure that the coeffiecient of the variable to be eliminated are equations in both expressions. To do that;

8p + 4g = 124

8p - q = 59

Subtract

4q + q = 124 + 59

5q = 183

The second required strategy is  to Multiply 8p-q=59 by 2, then add the result to 4p + 2q = 62, to have:

16p-2q=118

4p + 2q = 62

Adding up

16p + 4p = 118 + 62

20p = 180

p = 9

We can see that both strategies works since we can easily eliminate a variable from both equations.

Answer:

B(-3, -3)

Step-by-step explanation:

If a point O(x, y) divides line segment XY in the ratio of n:m and the endpoints of the segment are [tex]X(x_1,y_1)\ and\ Y(x_2,y_2)[/tex], the coordinates of O is:

[tex]x=\frac{n}{n+m}(x_2-x_1)+x_1 \\\\y=\frac{n}{n+m}(y_2-y_1)+y_1[/tex]

Given that A(6, -6) and C(-6, 2). Pont B is on AC such that:

AB = (3/4)AC

AB/AC = 3/4

Therefore point B divides the line AC in the ratio of 3:1. Let point B be at (x, y), therefore:

[tex]x=\frac{3}{3+1}(-6-6)+6=\frac{3}{4}(-12)+6=-9+6=-3\\ \\y=x=\frac{3}{3+1}(-2-(-6))-6=\frac{3}{4}(4)-6=3-6=-3[/tex]

Therefore the location of B is at (-3, -3)

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).

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$. So, she earned 606$.

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: The congruent corresponding parts:

∠P≅∠T  (first letter)  , ∠Q≅∠S (second letter), ∠R≅∠R (third letter)

segment PQ ≅ segment  TS , segment  QR≅ segment  SR , segment PR ≅ segment TR.

Step-by-step explanation:

We know that if two triangles area congruent then the corresponding parts area congruent.

Given: ΔPQR ≅ ΔTSR

Then, ∠P≅∠T  (first letter)  , ∠Q≅∠S (second letter), ∠R≅∠R (third letter)

segment PQ ≅ segment  TS , segment  QR≅ segment  SR , segment PR ≅ segment TR.

Hence, the congruent corresponding parts:

∠P≅∠T  (first letter)  , ∠Q≅∠S (second letter), ∠R≅∠R (third letter)

segment PQ ≅ segment  TS , segment  QR≅ segment  SR , segment PR ≅ segment TR.

The corresponding parts of a triangle are parts that have the same measurement.

The corresponding parts are: P & T, Q & S and R & R

The given parameter is:

[tex]\mathbf{\triangle pqr \cong \triangle tsr}[/tex]

The above congruence equation means that:

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

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.

The given function is [tex]y=x^2+7[/tex].

Minimum or maximum value:

At the extremum (maximum or minimum) value, the function will have zero slope. So, differentiate the given function once and equate it to zero to get the extremum point.

dy/dx=0

[tex]\Rightarrow 18x=0\cdots(i)[/tex]

[tex]\Rightarrow x=0[/tex]

Now, check whether the point x=0 is corresponding to the maximum value or minimum value by differentiating the function twice,

[tex]\frac {d^2y}{dx^2}=18[/tex]

As [tex]\frac {d^2y}{dx^2} >0[/tex] for all value of x, so x=0 is the point corresponding to minima.

Put x=0 in the given function to get the minimum value.

[tex]y_{min}=9(0^2)+7[/tex]

[tex]y_{min}=7[/tex]

Domain and range:

The function defined for all the values of the independent variable, x.

So, the domain is [tex](-\infty, \infty)[/tex].

The range of the function is the possible value of y.

The minimum value, for x=0, is y=7.

The maximum value, as [tex]x\rightarrow \infty \;or\; -\infty, y\rightarrow \infty[/tex].

Hence the range of the function is [tex][7,\infty)[/tex].

The value of x for which the function is increasing and decreasing:

If the slope of the function is negative than the function is decreasing, so

Then, from equation (i), the value of x for which dy/dx<0,

18x<0

[tex]\Rightarrow x<0[/tex]

Hence, the function is decreasing for [tex]x\in {-\infty, 0)[/tex] .

While if the slope of the function is positive than the function is increasing, so

Then, from equation (i), the value of x for which dy/dx<0,

18x>0

[tex]\Rightarrow x>0[/tex]

Hence, the function is increasing for [tex]x\in {0,\infty)[/tex]

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.
