The ratio of blue marbles to red marbles in a box is 3 to 2. if there are 12 blue marbles in a box then how many red marbles are there?
Answer:
8 red marbles.
Step-by-step explanation:
The ratio is 3:2, blue to red. If there's 12 blue marbles and the first part of the ratio's 3, then:
12/3=4
Then you take the 4 and multiply it by 2, the second half of the ration to get 8.
And so, the answer's 8. If you divide 12:8 by 4 each you get your original ratio of 3:2, so that's your way to check.

Two numbers have a sum of -15 and a
product of -100. What are the numbers?
Answer:
the numbers are -20 and 5
Step-by-step explanation:
The value of a = -20 and b = 5.
Let the numbers be a and b
a + b = -15 ...... i
a × b = -100 ....... ii
From equation i,
a = -15 - b ..... iii
Put equation iii into ii
a × b = -100
(-15 - b) × b = -100
-15b - b² = -100
-15b - b² + 100 = 0
b² + 15b - 100 = 0
b² + 20b - 5b - 100 = 0
b(b + 20) - 5(b + 20) = 0
b - 5 = 0
b = 0 + 5 = 5
a + b = -15
a + 5 = -15
a = -15 - 5
a = -20
Therefore, the value of a = -20 and b = 5.

Answer:
8.5
Step-by-step explanation:
The opposite of -8 is 8.
\frac{1}{2}+8
Convert 8 to fraction \frac{16}{2}.
\frac{1}{2}+\frac{16}{2}
Since \frac{1}{2} and \frac{16}{2} have the same denominator, add them by adding their numerators.
\frac{1+16}{2}
Add 1 and 16 to get 17.
\frac{17}{2}

Graph the rational function f(x)=(3x-1)/(x-5)
To graph the rational function f(x) = (3x - 1) / (x - 5), follow these steps. Find the vertical asymptote(s) by setting the denominator equal to zero and solving for x.
x - 5 = 0
x = 5
The vertical asymptote of the function is x = 5.
Step 1: Find the horizontal asymptote by comparing the degrees of the numerator and denominator polynomials. Since the degree of the numerator (3x - 1) is 1, and the degree of the denominator (x - 5) is also 1, the horizontal asymptote is given by the ratio of the leading coefficients:
Horizontal asymptote: y = 3/1
Horizontal asymptote: y = 3
Step 2: Find the x-intercept by setting the numerator equal to zero and solving for x:
3x - 1 = 0
3x = 1
x = 1/3
The x-intercept is (1/3, 0).
Step 3: Find the y-intercept by setting x to zero and evaluating the function:
f(0) = (3 * 0 - 1) / (0 - 5)
f(0) = -1 / -5
f(0) = 1/5
The y-intercept is (0, 1/5).
Step 4: Find additional points to sketch the graph. Choose some x-values around the vertical asymptote (x = 5) and calculate the corresponding y-values. For example, you can use x = 4, x = 6, and x = 8.
x = 4:
f(4) = (3 * 4 - 1) / (4 - 5)
= 11 / -1
= -11
x = 6:
f(6) = (3 * 6 - 1) / (6 - 5)
= 17 / 1
= 17
x = 8:
f(8) = (3 * 8 - 1) / (8 - 5)
= 23 / 3
≈ 7.67
Step 5: Plot the points obtained from Steps 2 to 5 and draw the graph. The graph should approach the horizontal asymptote (y = 3) as it approaches the vertical asymptote (x = 5).
The graph of the rational function f(x) = (3x - 1) / (x - 5) should look like this:
