Step-by-step explanation:
6x = 23² - 17²
6x = (23 + 17)(23 - 17)
6x = 40 * 6
Hence x = 40.
f(x)=4x 2 +6x−2 find f(-5)

Step-by-step explanation:
To work this out, we simply need to divide 1 3/4 miles by 4 9/10 miles.
1 3/4 ÷ 4 9/10
Start by converting both terms to improper fractions:
(4/4 + 3/4) ÷ (40/10 + 9/10)
= 7/4 ÷ 49/10
To divide, we simply multiply by the reciprocal of the second fraction:
7/4 * 10/49
= 70 / 196
Now we can take out common factors of the 70 / 196
70 / 196
= (5 * 2 * 7) / (14 * 2 * 7)
= 5 / 14
So the straight section of the track is five fourteenths of the entire length.
10. A local
meteorologist
estimated 3.5 inches of
rain for the month of
April. The actual rainfall
was 5.8 inches. What
was the percent error of
the estimate to the
nearest tenth of a
percent?
Answer:
39.7%
Step-by-step explanation:
(actual value - estimated value) / actual value
5.8 - 3.5 = 2.3
2.3 / 5.8 = 0.3965 = 39.65%

-4n(5n+6)-5(3+3n)
Answer: -20n^2 - 39n - 15
Step-by-step explanation:
first, we remove the parenthesis (multiply everything out).
-20n^2 - 24n - 15 - 15n
then, we simply collect like terms.
-20n^2 - 39n - 15
Answer:
-20n^2-39n-15
Step-by-step explanation:
Given: -4n(5n+6)-5(3+3n)
Use the distributive property: -20n^2-24n-15-15n
Combine like terms: -20n^2-39n-15
Your simplified expression is -20n^2-39n-15

Answer:
The system is consistent; it has one solution ⇒ D
Step-by-step explanation:
A consistent system of equations has at least one solution
The consistent independent system has exactly 1 solutionThe consistent dependent system has infinitely many solutionsAn inconsistent system has no solution
In the system of equations ax + by = c and dx + ey = f, if
a = d, b = e, and c = f, then the system is consistent dependent and has infinitely many solutionsa = d, b = e, and c ≠ f, then the system is inconsistent and has no solutiona ≠ d, and/or b ≠ e, and/or c ≠ f, then the system is consistent independent and has exactly one solutionIn the given system of equations
∵ -2y + 2x = 3 ⇒ (1)
∵ -5y + 5x = 12 ⇒ (2)
→ By comparing equations (1) and (2)
∵ -2 ≠ -5
∵ 2 ≠ 5
∵ 3 ≠ 12
→ By using the 3rd rule above
∴ The system is consistent independent and has exactly one solution
∴ The system is consistent; it has one solution

The ratio of sugar to flour in the recipe is 1 to
2. If you use 5 cups of sugar, how much flour do
you need to use?
Answer:
10 flour
Step-by-step explanation:
1:2
5:x all you have to do is multiply by 2, sense the ratio is 1:2, flour will always be 2 times greater than sugar. so the answer is 5 x 2 =10
A bookstore costs $96 a day to keep open, and it spends $12 for each book that it sells. If each book sells for $18, what is the break-even point
for this bookstore?
Answer: The break even point is when they have sold 16 books and have made $288
Step-by-step explanation: The costs are modeled in the equation y = 12x + 96. x is the number of books sold.
The earnings are modeled by he equation y = 18x.
Substitute 18x for y and solve for x.
18x = 12x + 96 Subtract 12x from both sides.
6x = 96 Divide both sides by 6
x = 16
Substitute into the original equations to solve for y
y = 12(16) + 96
y = 192 + 96
Y = 288
y = 18(16)
y = 288

Is this sequence arithmetic, geometric, or neither?
Answer:
Geometric sequence
.Step-by-step explanation:
Geometric sequences are defined by an initial value and a common ratio . If a sequence does not have a common ratio or a common difference, it is neither an arithmetic nor a geometric sequence. You should still try to figure out the pattern and come up with a formula that describes it.
Answer: Neither
Step-by-step explanation:
The difference between the roots of the quadratic equation x2 -14x +q =0 is 6. Find q
9514 1404 393
Answer:
q = 40
Step-by-step explanation:
When the quadratic has roots p and r, it can be factored as ...
(x -p)(x -r) = x² -(p+r)x +pr
So, the sum of the roots is 14, and their difference is 6. This lets us find the roots from ...
p + r = 14
p - r = 6
2p = 20 . . . add the two equations
p = 10
r = 14 -p = 4
The value of interest is then ...
q = pr = (10)(4)
q = 40
__
The graph shows the roots to be 4 and 10, as we found.

What are the domain and range of each relation?
Drag the answer into the box to match each relation.
Answer:
Please check the explanation.
Step-by-step explanation:
We know that the domain of a function is the set of input or argument values for which the function is real and defined.Thus, the domain of the first relation is: {-2, -1, 0, 2}
We also know that the range of a function is the set of values of the dependent variable for which a function is defined.Thus, the range of the first relation is: {-4, -2, 2}
Given the second relation
x y
-4 -2
-2 1
1 4
4 4
We know that the domain of a function is the set of input or argument values for which the function is real and defined.Thus,
The domain of the second relation is: {-4, -2, 1, 4}
We also know that the range of a function is the set of values of the dependent variable for which a function is defined.Thus,
The range of the second relation is: {-2, 1, 4, 4}
A list contains 7 consecutive even numbers in ascending order.The largest number is 30 and the smallest is 12 less than this.The mode is 20 and median is 22.If the sum of the two remaining numbers is 50,find all the number
Answer:
18, 20, 20, 22, 24, 26, 30
Step-by-step explanation:
We know that the largest number of the list is 30 and the smallest number is 12 less than that, which is 30 - 12 = 18.
This is our list so far: 18, __ , __ , __ , __ , __ , 30
The median of a set is the middle number of the set. In this case, since there are 7 terms in the set, the median, which the problem states is 22, must be the 4th number, since the 4th number is in the middle.
This is our list now: 18, __ , __ , 22, __ , __ , 30
Now, let's deal with the mode. The mode of a set is the term that shows up the most. Since the set is in ascending order and 20 < 22, we know that the two numbers in between 18 and 22 must be 20 and 20. This means that no term can show up more than once, with the exception of 20 because it is the mode.
This is our list now: 18, 20, 20, 22, __ , __ , 30
Finally, we'll deal with the last two numbers. We know that they must be even and that they both must be in between 22 and 30 (since the set is in ascending order). We also know that the two numbers must be different (see last paragraph) and that they sum to 50. The only two numbers that satisfy all of these conditions are 24 and 26, so they must be our last two numbers.
Therefore, the answer is 18, 20, 20, 22, 24, 26, 30. Hope this helps!

Calculate the frequency of light that has a wavelength of
4.25 x 10^-9m and a velocity of 300 m/s.
Answer:
The velocity of light, v, is the product of its wavelength, λ , and its frequency, f. This means that the wavelength is the velocity, v, divided by the frequency, f.
Wavelength of light = velocity of light / frequency of light
λ = v/f
λ = Wavelength of light, meters
v = Velocity of light (c = 3.0 x 108 m, for speed of light if not otherwise defined)
f = frequency of light, Hz
