Step-by-step explanation:

The formula of a distance between two points:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

We have the points (7, -4) and (7, 9). Substitute:

Used [tex]\sqrt{a^2}=a[/tex]

Answer:

We have the following equations:

5 + 3x - 2 and x + 2(x+1) + 1

Before checking the statements. Let's solve the syste of equations:

5 + 3x - 2 = x + 2(x+1) + 1

5 + 3x - 2 = x + 2x+2 + 1

3x + 3 = 3x + 3

Both equations are equivalent. Now, let's judge the statements:

1. The expressions are only equivalent when evaluated with odd values.

Given that the both expression are the same, the expressions are equivalent for ALL values.

Therefore, the statement IS FALSE ❌

2. The expressions are only equivalent for x=3 and x=7.

Given that the both expression are the same, the expressions are equivalent for ALL values, not only x=3 and x=7.

Therefore, the statement IS FALSE ❌

3. The expressions should have been evaluated with one odd value and one even value.

If two expressions are equivalent, they should be equivalent for ALL values. Sometimes, evaluating just one odd and one even value isn't enough. That's why the best approach is to solve the system of equations.

Therefore, the statement IS FALSE ❌

4. The expressions have equivalent values when x=6.

Given that the both expression are the same, the expressions are equivalent for x=6 (And all the real values too).

Therefore, the statement IS TRUE ✅

5. When x=0, the first expression has a value of 3 and the second expression has a value of 4.

Given that BOTH expressions are equvalent, they have the same value when x=0, which is 3.

Therefore, the statement IS FALSE ❌

6. The expressions have equivalent values for any value of x.

Given that the both expression are the same, the expressions are equivalent for ALL values of x.

Therefore, the statement IS TRUE ✅

7. When x=10, both expressions have a value of 33

Given that the both expression are the same, the expressions are equivalent for ALL values of x. That's why when x=0, both expressions have a value of 33.

Therefore, the statement IS TRUE ✅

The area of this figure is 946 square inches.

We can see that the figure is composed by two rectangles with diferrent dimensions, so, to calculate the area of the entire figure.

So,

For the first rectangle, we have:

[tex]Base=7in\\Height=28in[/tex]

The area will be:

[tex]Area=Base*Height=7in*28in=196in^{2}[/tex]

For the second rectangle, we have:

[tex]Base=25in\\Height=30in[/tex]

The area will be:

[tex]Area=Base*Height=30in*25in=750in^{2}[/tex]

Now, calculating the area of the entire figure, we have:

[tex]TotalArea=FirstRectangleArea+SecondRectangleArea\\\\TotalArea=196in^{2}+750in^{2}=946in^{2}[/tex]

Answer:

Let's solve your system of equations by elimination.

8x+9y=48;12x+5y=21

Steps:

Multiply the first equation by 5,and multiply the second equation by -9.

5(8x+9y=48)

−9(12x+5y=21)

Becomes:

40x+45y=240

−108x−45y=−189

Add these equations to eliminate y:

−68x=51

Then solve−68x=51for x:

−68x /−68 = 51 /−68  (Divide both sides by -68)

x=  −3 /4

Now that we've found x let's plug it back in to solve for y.

Write down an original equation:

8x+9y=48

Substitute

−3 /4

8x+9y=48:

8( −3 /4 )+9y=48

9y−6=48 (Simplify both sides of the equation)

9y−6+6=48+6 (Add 6 to both sides)

9y=54

9y /9  =  54 /9  (Divide both sides by 9)   y=6

Answer:  x=  −3 /4  and y=6

Step-by-step explanation:

Given that slope of the line is m = 1

And the line passes through the point (-3,5).

Now we need to graph the line using above information. So begin by graphing the point (-3,5).

Slope means rise/run

Then slope = 1 means rise/run=1=1/1

means move point 1 unit up then 1 unit right

then new point is at (-2,6).

Now draw a line joining both points to get the final graph.

Answer:

(2, 5)

Step-by-step explanation:

Given the 2 equations

y = x + 3 → (1)

- 2x + y = 1 → (2)

Substitute y = x + 3 into (2)

- 2x + x + 3 = 1

- x + 3 = 1 ( subtract 3 from both sides )

- x = - 2 ( multiply both sides by - 1 )

x = 2

Substitute x = 2 into (1) for corresponding value of y

y = 2 + 3 = 5

Solution is (2, 5)

To determine if filling a tank takes longer than an hour, calculate the tank's volume, convert it to liters, and then divide by the fill rate. With a 240π liter capacity and a 0.2 L/s fill rate, it takes approximately 1.05 hours, thus longer than 1 hour.

To determine if it takes longer than 1 hour to fill a water tank with a radius of 40 cm and depth of 150 cm at a rate of 0.2 liters per second, we first calculate the volume of the tank and then the total time required to fill it at the given rate.

Step 1: Calculate the Volume of the Tank

Volume of a cylinder = πr²h, where r is the radius and h is the height.
Here, r = 40 cm and h = 150 cm.

Volume = π(40²)(150) = π(1600)(150) = 240000π cm³.

Step 2: Convert the Volume to Liters

Since 1 liter = 1000 cm³, the volume in liters = 240000π / 1000 = 240π liters.

Step 3: Calculate the Filling Time

Time = volume / rate = 240π / 0.2 = 1200π seconds.
To convert to hours, divide by 3600 (the number of seconds in an hour).

Total time in hours = 1200π / 3600 = π/3 hours, which is approximately 1.05 hours.

Since it takes approximately 1.05 hours to fill the tank, it does take longer than 1 hour to fill the tank.

Answer:

a) yes they are similar

b)Proved below

c)Proved below

Step-by-step explanation:

a) rectangle 1 and 2 are similar by definition of similar rectangles.

Definition of similar rectangles states that two rectangles are similar if they have same shape but different sizes. The ratio between their corresponding sides are same, in this case as rectangle 2 is made by multiplying each dimension of Rectangle 1 by a

factor of k, where k>0 thus providing same proportion in length of different corresponding sides of two rectangles hence rectangle 1 and 2 are similar.

b) Perimeter of rectangle 1, P1= s1+ s2+ s3 + s4

As each side of rectangle 2 is formed by multiplying each dimension of Rectangle 1 by k, therefore

  Perimeter of rectangle 2, P2= k.s1+ k.s2+ k.s3 + k.s4

Taking k common

                                                  = k(s1+ s2+ s3 + s4)

Substituting P1 in above expression

                                               P2  =k(P1)

Hence the perimeter of Rectangle 2 is k times the perimeter of Rectangle 1.

c) Area of rectangle 1, A1= 2(s1)(s2)

As each side of rectangle 2 is formed by multiplying each dimension of Rectangle 1 by k, therefore

Area of rectangle 2, A2= 2(k.s1)(k.s2)

                                       = 2k^2(s1)(s2)

                                        = k^2 [2(s1)(s2)]

Substituting A1 in above expression

                                        A2 = k^2(A1)

Hence the area of Rectangle 2 is k2 times the area of Rectangle 1 !

The divisor is x-1 and dividend is [tex]4x^2+6x-2[/tex]

By synthetic division we get the following:

Thus remainder is 8

Answer:

x=-4 and x=2

Step-by-step explanation:

You are given the function

[tex]f(x)=\dfrac{x^2+2x-8}{x^2-2x-8}[/tex]

The zeros of the function are those value of x, for which [tex]f(x)=0[/tex]

First, find x for which function is undefined

[tex]x^2-2x-8\neq0\\ \\x^2-4x+2x-8\neq 0\\ \\x(x-4)+2(x-4)\neq 0\\ \\(x-4)(x+2)\neq 0\\ \\x\neq 4\text{ and }x\neq -2[/tex]

Now find points at which f(x)=0:

[tex]f(x)=0\Rightarrow x^2+2x-8=0\\ \\x^2+4x-2x-8=0\\ \\x(x+4)-2(x+4)=0\\ \\(x-2)(x+4)=0\\ \\x=2\text{ or }x=-4[/tex]

For both these values (x=-4 and x=2) function f(x) is defined, then x=-4 and x=2 are zeros of the function.

Final answer:

To find the zeros of the given function, set the numerator equal to zero and solve for x. The zeros are x = -4 and x = 2.

Explanation:

We can notice that both the numerator and denominator share the same factors (x² - 2x - 8). This means that f(x) is undefined where the denominator is zero.

Therefore, the zeros of the function f(x) = x² + 2x - 8 / x² - 2x - 8 can be found by setting the numerator equal to zero and solving for x.

By factoring the numerator and denominator, it becomes easier to identify the zeros.

x² - 2x - 8 = 0

Factoring the expression:

(x - 4)(x + 2) = 0

Therefore, the zeros of the function f(x) are x = 4 and x = -2.
