Given :
The total cost can be represented by the equation 2c + (c+5) = 43.97, where c is the cost of one lower-priced cd.
To Find :
The cost of the higher priced cd.
Solution :
Solving given equation :
2c + c + 5 = 43.97
3c + 5 = 43.97
3c = 43.97 - 5
3c = 38.97
c = $12.99
Therefore, cost of higher priced cd is $( 12.99 + 5 ) = $17.99 .
Hence, this is the required solution.

What is the point-slope equation of the line that is perpendicular to the line shown and passes through (-4, -3)?
Answer:
y+3= -4x
Step-by-step explanation:
general equation is (y-y1) = m(x-x1)
m=rise/run= -4/1 (is negative because looking from left to right on the graph it goes downward)
pick any point on the line to put in. the equation for example (0,-3)

The formula for the pH of a solution of hydronium ions is given by the logarithmic equation pH=-log [H3O+], where [H3O+] is the hydronium ion concentration. Find the pH of a certain agricultural product with the hydronium ion concentration of 3.2 x 10-4
Answer:
3.5
Step-by-step explanation:
The formula for the pH of a solution of hydronium ions is given by the logarithmic equation pH=-log [H3O+], where [H3O+] is the hydronium ion concentration. Find the pH of a certain agricultural product with the hydronium ion concentration of 3.2 x 10^-4
We have the Logarithmic equation
pH=-log [H3O+],
We have the hydronium ion concentration = 3.2 x 10^-4
Hence,
pH = - log[3.2 × 10 ^-4]
pH = 3.4948500217
Approximately
pH = 3.5
Therefore, the pH of a certain agricultural product with the hydronium ion concentration of 3.2 x 10^-4 is 3.5

Kayla squared a number x and added this result to -6.5. This gave her an answer of 42.5.
What is the equation and one of the solutions to this equation?
A.X2 + (-6.5) = 42.5; 2 = 7
B.X2? + (-6.5) = 42.5; 2 = 6
C.2x+ (-6.5) = 42.5; x = 24.5
D.2x+ (-6.5) = 42.5; I = 18
Answer:
7, -7
Step-by-step explanation:
x^2-6.5= 42.5 add 6.5 to both sides
x^2= 49
The square root of 49 is 7 and -7.

Using the triangle find x and y
Classify the triangle by angles and sides
The perimeter of the triangle is 25 units
Answer:
see explanation
Step-by-step explanation:
Since the base angle are congruent, both 44° then the triangle is isosceles.
Then the 2 legs are congruent, that is
4x - 7 = 2x + 1 ( subtract 2x from both sides )
2x - 7 = 1 ( add 7 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Thus legs are both 4x - 7 = 4(4) - 7 = 16 - 7 = 9 and base = x + 3 = 4 + 3 = 7
As a check 9 + 9 + 7 = 25 → correct
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the base angles from 180 for y, that is
y = 180 - (44 + 44) = 180 - 88 = 92
Finally
x = 4
y = 92
angles are 92°, 44° and 44°
sides are 9, 9 and 7

What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The Numbers constants, variables, operations, functions, brackets, punctuation, and grouping are mathematical symbol; which can also be used to indicate the logical syntax's order of operations and other features.
Based on the law of exponents power of a power property we have:

Answer:
The rise is 5
The run is 6
The rate is 5/6
Step-by-step explanation:
Rise is the change in y, or how many units up the line goes. On this graph, y goes up 5. The run is the change in x, or how many units right the line goes; on this graph, it goes 6 units right in between the points. The rate, or slope, is rise over run, so the final answer is 5/6.
