identify a possible pair of values for a and c so that ax^2 + 10x = c has one real solution. Then write the equation.

The solution is a = 5 and c = - 5

What is the equation?

Answers

9514 1404 393

Answer:

5x^2 +10x = -5

Step-by-step explanation:

The equation will have one solution when the discriminant is zero.

In standard form, the equation is ...

ax^2 +10x -c = 0

The discriminant of the equation ax^2+bx+c=0 is ...

b^2 -4ac

so the discriminant of your equation is ...

10^2 -4a(-c) = 100 +4ac

We want that to be zero, so we require ...

100 +4ac = 0

25 +ac = 0

ac = -25

Any pair of values of 'a' and 'c' that have a product of -25 will satisfy the requirement. As you state, one possible pair is a = 5 and c = -5. Putting these values into the given equation makes it ...

5x^2 +10x = -5 . . . . . the equation with a=5, c=-5

_____

Additional comment

Your problem statement does not require that 'a' be non-zero. If a=0, then the equation will have one real solution for any value of c.

If you restrict the solutions to integers, then possibilities include ...

(a, c) = (1, -25), (5, -5), (25, -1), (-25, 1), (-5, 5), (-1, 25)

Answer:

The equation is 5x+10x=-5

Step-by-step explanation:

Solve the equation for x:
4x2 + 15x = 4
Show steps please

Answers

4 x 2 + 15x = 4
First multiply the 4 and 2
8 + 15x = 4
Next, subtract the 8 on both sides
15x = -4

7) (Extra Credit) A chemist needs to mix a 12 % solution with a 20% solution to obtain 180 ounces of a 15% solution. How many ounces of each of the solutions must be used? 12%________ 20%__________

Answers

Answer:

Step-by-step explanation:

Let x be the amount of 12%

Let y be the amount of 20%

x + y = 180

x = 180 - y

x(0.12) + y(0.20) = 180(0.15)

(180 - y)(0.12) + y(0.20) = 27

(180)(0.12) - 0.12y + 0.20y = 27

21.6 + 0.08y = 27

0.08y = 5.4

y = 67.5 oz of 20% solution

x = 180 - 67.5 = 112.5 oz of 12% solution

In a particular country, 3% of the population is HIV positive. A test for HIV correctly
diagnoses 95% of those who have the condition, but incorrectly diagnoses 4% of those
who are not HIV positive as being HIV positive. A patient obtains a positive test result,
apparently indicating the presence of HIV. Determine the probability that the patient
really is HIV positive.

Answers

Using conditional probability, it is found that there is a 0.4235 = 42.35% probability that the patient really is HIV positive.

Conditional Probability

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened. [tex]P(A \cap B)[/tex] is the probability of both A and B happening. P(A) is the probability of A happening

In this problem:

Event A: positive test.Event B: HIV positive.

The percentages involving a positive test are:

95% of 3%(positive)4% of 100 - 3 = 97%(not positive).

Hence:

[tex]P(A) = 0.95(0.03) + 0.04(0.97) = 0.0673[/tex]

The probability of both having a positive test and being HIV positive is:

[tex]P(A \cap B) = 0.95(0.03)[/tex]

Then, the conditional probability is:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.95(0.03)}{0.0673} = 0.4235[/tex]

0.4235 = 42.35% probability that the patient really is HIV positive.

f(x) = -3/2x +5

Step-by-step explanation:

The differences between the x-values are all 2.

The differences between the y-values are all -3.

When the ratios of the differences are constant, the function is linear. The slope is ...

m = Δy/Δx = -3/2

The y-intercept is given by the table value where x=0: b=5.

Then the slope-intercept equation is ...

f(x) = mx +b
