Answer:
They often have more than one solution.
Answer:
Step-by-step explanation:
Quadratic equations are equations that when rearranged using the 5 operations can yield a polynomial of degree 2 on one side of the equation and 0 on the other. There are 3 commonly taught methods for solving quadratic equations. These methods are factoring, completing the square, and the quadratic formula. These functions are most commonly used to model projectiles, disregarding air resistance.
When using the factoring method one attempts to write a degree 2 polynomial as the product of two degree 1 polynomials. This method works because if we multiply two degree one polynomials together we find
For example: When factoring , we want to find two number a, b whose product is 6 and sum to 5. The values of a and b we are looking for are 2 and 3.
The method of completing the square centers around using the five operations to replace the original equation with an equivalent equation of the form by taking advantage of the fact that
The absolute value function takes the value of a number, regardless of whether it is positive or negative. Some problems that the absolute value is useful for modeling include an object bouncing on the ground.
For example, , since we do not care about the negative sign.
Example: Solve
Solution: Since the absolute value does not care about whether a number is positive or negative, if then or . Then we can solve each equation individually to find that x = 1 or 5.

The solution set in which all the the possible values of x which satisfy the given compound inequality is -
x ∈ A , where A = (- ∞, -1)
What is inequality?
In mathematics, inequality refers to a relationship that makes a non-equal comparison between two numbers or other mathematical expressions.
Given is the following compound inequality -
2(x – 2) + 7 > –1
and
5 – 4x > 9
Inequality - 1
2(x – 2) + 7 > –1
2x - 4 + 7 > - 1
2x + 3 > - 1
2x + 3 - 3 > - 1 - 3
2x > -4
x > -2
x < 2
Inequality - 2
5 – 4x > 9
5 - 5 - 4x > 9 - 5
- 4x > 4
-x > 1
x < - 1
Since x < - 1 and x < 2, therefore the inequality → x < -1 represent all the solutions. We can write the solution set as -
x ∈ A , where A = (- ∞, -1)
Therefore, the solution set in which all the the possible values of x which satisfy the given compound inequality is -
x ∈ A , where A = (- ∞, -1)

Joel’s veterinarian tells him that he can give his dog 11 5/8 mg of Benadryl for relief of his dogs allergies. Joel’s dog weighs 15 1/2 pounds.
Part a: what is the Benadryl dosage per pound for Joel’s dog?
Part b: If Joel’s veterinarian always uses the same milligrams per pound for prescribing aspirin to dogs, what would she prescribe for a dog that weighs 12 pounds?
Step-by-step explanation:
Given that,
The dosage of Benadryl for Dog is [tex]11\dfrac{5}{8}\ mg[/tex]
Weight of Joel's Dog is [tex]15\dfrac{1}{2}\ \text{pounds}[/tex]
(a) Benadryl dosage per pound for Joel’s dog is calculated as :

Answer:
so here we are told that angle CED is 39 degrees and in this diagram we have three angles the first one is Angle CED the next one is angle CEL and the last one is angle LED so angle c e l + angle LED is equals to angle c e d so in this case 3 x - 6 + x + 25 should be equal to 39 degrees collect the like terms 3 x + x + 25 - 6 is equals to 39 degrees 4X + 19 is equals to 39 cross the 19 over the equals sign that you have 4 x is equals to 39 + 19 4 x is equals to 68 divide both sides by 4 and x is equals to 17 then substitute replace where there is x with seventeen so in this case angle c e l will be 3 * 17 -6 we are multiplying 3 by 17 because it was 3 x and we got the value of x to be 17 so 3 * 17 is 51 -6 is 45 so angle CEL is 45 degrees you can do the same with the other angle that is angle LED and you get x to be 42

a leftward shift of the supply curve for widgets, ceteris paribus will cause equilibrum price to
A. Rise and equilibrium quantity to rise
B. fall and equilibrium quantity to fall
C. Rise and equilibrium quantity to fall
D. Fall and equilibrium quantity to remain unchanged
Answer: c. Rise and equilibrium quantity to fall
Step-by-step explanation:
The supply curve shows the relationship that exists between the price of a product and the quantity that's been sold by the consumer.
A leftward shift of the supply curve for widgets implies that there's a reduction in the quantity supplied. Since there's a reduction, there'll be few widgets which will lead to increase in equilibrium price and fall in the quantity.

this is due tonight and i really need this answer, whoever answers god bless.
Answer:
a. f(1) = -4
b. One value of x for which f(x) = -1 : 2 (or -2)
Step-by-step explanation:
a. To find f(1), we would have to find what the value of the function would be when x = 1. By using the given graph, we can find the f(1) by finding what the y-value is when x = 1. Looking at the graph, we can see that when x = 1, y = -4. Thus, f(1) = - 4.
b. Now we are also asked to find one value of x for which f(x) = -1. In other words, what values of x would make the value of the function equal to -1? We can find values of x for which f(x) = -1 by using the graph and seeing for which x-values would the y-value be -1. We can see that y = -1 at x = -2 and x = 2. So the values of x at which f(x) = -1 are -2 and 2. You can choose either one of these values.

Eagletrons are all electric cars produced by Mogul motors. One of the concernsof Mogul is that the Eagletrons be capable of achieving appropriate maximumspeeds. To monitor this, Mogul executives take samples of 8 Eagletrons at atime. For each sample, they determine the average maximum speed and the rangeof the maximum speeds within the sample. They repeat this with 35 samples toobtain 35 sample means and 35 ranges. They find that the average sample mean is88.50 mph and the average range is 3.25 mph. Using these results, theexecutives decide to establish an R chart. They would like this chart to beestablished so that when it shows that the range of a sample is not within thecontrol limits, there is only approximately a .0027 probability that this is dueto natural variation. What will the upper control limit (UCL) and the lowercontrol limit (LCL) in this chart?
Trying to confirm that what I came up with is correct.
Answer:
upper control limit = 6.058
lower control limit = 0.442
Step-by-step explanation:
Given that:
The numbers of sample n Mogul executives took = 8 Eagletrons at a time.
They find out that the average sample mean is 88.50 mph and;
the average range [tex]\overline r[/tex] is 3.25 mph.
From the tables:
[tex]\text {Table values for n = 8 } \left \{ {{D_4=1.864} \atop {D_3=0.136}} \right.[/tex]
Control Limit = [tex]\overline r[/tex] = 3.25
Therefore; the upper control limit and the lower control limit can be computed as follows:
upper control limit = [tex]D_4 \overline r[/tex]
upper control limit = 1.864(3.25)
upper control limit = 6.058
lower control limit = [tex]D_3 \overline r[/tex]
lower control limit = 0.136(3.25)
lower control limit = 0.442

Point A is located at negative 4 over 6 and point B is located at negative 1 over 6. What is the distance between points A and B?
negative 4 over 6 minus negative 1 over 6 = negative 3 over 6; therefore, the distance from A to B is absolute value of negative 3 over 6 equals negative 3 over 6 units
negative 4 over 6 minus negative 1 over 6 = negative 3 over 6; therefore, the distance from A to B is absolute value of negative 3 over 6 equals 3 over 6 units
negative 4 over 6 plus negative 1 over 6 = negative 5 over 6; therefore, the distance from A to B is absolute value of negative 5 over 6 equals 5 over 6 units
negative 4 over 6 plus negative 1 over 6 = negative 5 over 6; therefore, the distance from A to B is absolute value of negative 5 over 6 equals negative 5 over 6 units

We want to write a paragraph proof to prove the following theorem:
If ∠N and ∠M are congruent and supplementary, then ∠N and ∠M are right angles.
Each sentence is numbered:
1) Because ∠N and ∠M are congruent, m∠M = m∠N by the definition of congruent angles.
2) Because ∠N and ∠M are supplementary, m∠M + m∠N = 180.
3) Substitute m∠M to m∠N to get m∠M + m∠M = 180, or 2m∠M=180.
4) The Division Property of Equality then yields m∠M = 90.
5) Substitute m∠N for m∠M to get m∠N = 90.
6) By the definition of right angles, ∠N and ∠M are right angles.
