Answer:

  a) (a, b) = (3, 5) or (3, -5)

  b) (a, b) = (2, 3)

Step-by-step explanation:

Generally, you solve systems like this by dividing one equation by the other. This gives you the value of the base (b). Substituting that into either equation gives you the scale factor (a).

__

a) Since b^0 = 1, you already have the solution for 'a': 3 = a. Substituting that into the second equation gives ...

  75 = 3b^2

  b = √(75/3) = √25 = 5

Since both exponents of b are even, there is no reason why b could not be -5.

Possible solutions: (a, b) = (3, 5) or (3, -5).

__

b) Dividing the second equation by the first gives b:

  [tex]\dfrac{54}{18}=\dfrac{a\cdot b^3}{a\cdot b^2}\\\\3=b \qquad\text{simplified}\\\\18=a\cdot3^2\qquad\text{substitute for b}\\\\\dfrac{18}{9}=a=2\qquad\text{divide by 9}[/tex]

The solution is (a, b) = (2, 3).

_____

Additional comment

Usually, we're only interested in positive solutions for 'b'. Negative values usually only make sense when the exponent is an integer, as in the case of an exponential sequence.

The image shows a rectangle and its two diagonals. The measurement of angle A is 25º. The measurement of angle B is also 25°. What is the measurement of angle L? Complete the steps below to solve the problem.

Part A

From the given angle measurements, you can't directly find the measure of angle L. However, you can find the measurement of angle C, which is supplementary to angle L. Describe how to find the measurement of angle C using the measurements of angle A and angle B.



Part B
write a numerical expression for the measurement of angle C.

Part C. what is the measurement of Angle C.

part D. Describe how to find the measurement of angle L using angle C.

Part E. Write an expression for measurement of angle L using the measurement of angle C found in part C.

Part F. What is the measurement of angle L.

(no way anyone is gonna do all this if you can that would be amazing)

​

Answers

Answer:

part A : Angles A, B, and C form a triangle. The sum of the angle measurements of a triangle is 180°. So, I can find the measurement of angle C by subtracting the measurements of angle A and angle B from 180°.

part B: Angle A and angle B each measure 25°. Find the measurement of angle C by subtracting the measurements of angle A and angle B from 180°. The numerical expression for the measurement of angle C is 180° – 25° – 25°.

part C: The measurement of angle C is given by the expression 180° – 25° – 25°. So, angle C measures 130°.

part D:Angle L and angle C are supplementary angles. The sum of supplementary angles is 180°. So, I can find the measurement of angle L by subtracting the measurement of angle C from 180°.

part E: Angle C measures 130°. Find the measure of angle L by subtracting the measurement of angle C from 180°. The numerical expression for the measure of angle L is 180° – 130°.

part F: The measurement of angle L is given by the expression 180° – 130°. So, angle L measures 50°.

(b)The perimeter of a rectangular painting is 374 cm. If the width of the painting is 88cm, what is its length?

Answers

Answer:

part a is 54            part b is 99

Step-by-step explanation:

72 x ? =3888

x=54

374 is the perimeter. You have a side that is 88cm so the opposite side will be 88 cm as well. 374-176=198

so between the last 2 sides we have 198. The sides will be equal so you just divide it by 2  

so the top and bottom of the rectangle are 99 and both sides are 88
