Quadrilateral b, is not a scaled copy of Quadrilateral a.

The side length of Quadrilateral a=2,3,5, and 6.

The side length of Quadrilateral b=4,5,8 and 10

Now comparing the Ratio of the Corresponding Sides of two quadrilaterals a and b

2/4 ≠ 5/8

3/5 ≠  6/10

Since the ratio of corresponding opposite sides is not equal. The two Quadrilateral are Not Similar.

So, We can say that Quadrilateral b, is not a scaled copy of Quadrilateral a.

The value of the function f(-8) if f(x) = -x^2 +8x + 4 is f(-8) = -124

The equation of the function is given as

f(x) = -x^2 +8x + 4

The expression f(-8) means that x = -8

So, we have:

f(-8) = -(-8)^2 + 8(-8) + 4

Evaluate the exponent and the product

f(-8) = -64 - 64 + 4

Evaluate the sum and the difference

f(-8) = -124

Hence, the value of the function f(-8) if f(x) = -x^2 +8x + 4 is f(-8) = -124

The possible coordinates of point G on this number line are either -10 or 14.

A number line can be defined as a type of graph with a graduated straight line which contains both positive and negative numerical values that are placed at equal intervals along its length.

Given the following data:

E = 2.

EG = 12.

On this number line, the coordinate of EG is given by this mathematical expression:

EG = |E - G|

Substituting the given parameters into the expression, we have;

12 = |2 - G|

2 - G = ±12

G = 2 ± 12

Simplifying and evaluating the above expression, we have:

G = 2 + 12

G = 14.

OR

G = 2 - 12

G = -10

Therefore, the possible coordinates of point G on this number line are either -10 or 14.

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

Explanation:

The term "rate of change" is the same as "slope" for linear equations.

Use the slope formula to get the steps shown below.

[tex](x_1, y_1) = (-3, 3.6) \text{ and } (x_2, y_2) = (5, 2)\\\\m = \frac{y_2 - y_1}{x_2 - x_1}\\\\m = \frac{2-3.6}{5-(-3)}\\\\m = \frac{2-3.6}{5+3}\\\\m = \frac{-1.6}{8}\\\\m = \frac{-16}{80}\\\\m = -\frac{1}{5}\\\\m = -0.2\\\\[/tex]

The decimal value is exact without any rounding done to it.

A slope of -1/5 means we go down 1 unit and to the right 5 units.

slope = rise/run = -1/5

rise = -1 = go down 1

run = 5 = go to the right 5

To solve the equation, add 18 to both sides, then divide by 6. The solution is t = 8.

A linear equation is an equation of which the highest degree of its variables is 1.

Steps to solve linear equations:

Recall that if  we subtract or add the same number to both sides of an equation, it does not change the equality.

The given problem:

Solve 6t-18 = 30

The variable is t. Isolate the variable by adding 18 to both sides:

6t -18 +18 = 30 +18

6t = 48

Divide both sides by 6

6t : 6 = 48 : 6

Let the dimensions be represented by x and x+2.

The perimeter of a rectangle is:

Using complementary and supplementary angles, we have that:

c. The angles are complementary, hence the equation is 4x - 3 + 2x + 1 = 90 and the solution is x = 15.33.

d. The angles are supplementary, hence the equation is 43x + 16 + 110 = 180 and the solution is x = 18.

When the measures of two angles add to 90º, the angles are complementary.

This is the case in item c, hence:

4x - 3 + 2x + 1 = 90

6x = 92

x = 92/6

x = 15.33.

When the measures of two angles add to 180º, the angles are supplementary.

This is the case in item d, hence:

3x + 16 + 110 = 180.

3x = 54

Let in 3 hours of driving, they completed the 'x' miles of distance from their home.

So, they complete the rest of the trip of 544 - x miles on the second day.

Let t be the time in hours they drive on the second day.

Their average speed is 64 miles per hour.

Answer: 36 years old

Step-by-step explanation:

T=Tanya. M=Marcus

T=M+28

T+6=3(M+6)

T+6-6=3(M+6)-6

T=3(M+6)-6

M+28=3(M+6)-6

M+34=3M+18

34=2M+18

2M=16

M=8

T=M+28

T=8+28

T=36 years old

The current age of Tanya is equivalent to 45 years old.

Given is that Tanya is 28 years older than Marcus. In 6 years, Tanya will be three times as old as Marcus

Assume the initial age of Tanya is {x} years and that of Marcus is {y} years old. So, we can write -

x = y + 28         ....... Eq[1]

x + 6 = 3y         ........ Eq[2]

Using Eq[1] in Eq[2], we get -

y + 28 + 6 = 3y

y + 34 = 3y

2y = 34

y = 17

Than, we can write [x] as -

x = 17 + 28

x = 45

Therefore, the current age of Tanya is equivalent to 45 years old.
