Answer:
b = {0, 1, 2, 3, 4, 5}
Step-by-step explanation:
The domain of a function is simply all the possible values the independent variable can assume that the function will work and will give a real number.
In this question, we have:
m = 45 – 8b
b is the independent variable because the money, m, depends on the number of books, b, bought.
Since we can't have negative value for m as it represents an amount of money, then the values b can assume can be gotten through:
45 – 8b = 0,
8b = 45
b = 45/8 = 5.625
For the m, money, to remain positive b shouldn't go beyond 5.625
Also we should note that b, books, can't be a negative (no such thing as negative books) or a fractional value (no such thing as buying parts of a book) as well. Therefore, b = {0, 1, 2, 3, 4, 5}
Ok so first find the area on the triangle where is gives the length and width and the formula for the area of a triangle is Length x widthsx 0.5 so 5.2x8x0.5=20.8 square inches . Then to find the area of the other triangle you have to use Pythagorean’s theorem to find the length because we know the hypotenuse is 6.8 and the width is the same as the other side so width is 5.2 the we will do a^2=c^2-b^2 so a^2=6.8^2-5.2^2 a^2=46.24-27.04 a^2= 19.2 and the square root of 19.2= 4.38 so find the area of that triangle 5.2x4.38x0.5=11.4 square inches then add the two areas together to get 32.2 square inches
Answer:
Step-by-step explanation:
To solve systems of algebraic equations containing two variables, start by moving the variables to different sides of the equation. Then, divide both sides of the equation by one of the variables to solve for that variable. Next, take that number and plug it into the formula to solve for the other variable.
That’s the answer with steps
