Answer: Choice C) no solution
=============================================================
Explanation:
The first equation says that y and 3x-4 are the same thing.
So we can replace every copy of "y" in the second equation with "3x-4" like so
9x - 3y = 14
9x - 3(3x-4) = 14
9x - 9x + 12 = 14
0x + 12 = 14
0 + 12 = 14
12 = 14
The last equation is false because we get different values on either side. Because the last equation is false, it means the equation 9x-3y = 14 is false when y = 3x-4.
In short, the overall systems of equations is inconsistent and that leads to no solution (choice C).
If you were to graph each equation, you should find that both lines are parallel. Parallel lines never intersect. The solution is the intersection point of any graphed system.

A weatherman predicted 8 inches of snow would fall last night.
Instead, 20 inches of snow actually fell.
What is the percent error of the prediction?
about 12%
about 40%
about 60%
about 150%
Answer:
The correct answer is - about 60%
Step-by-step explanation:
Given:
predicted value: 8 inches
measured value - 20 inches
formula:
Prediction percentage error is the error or differences between the prediction made and the observed or actual value. Calculation of the percentage error by the following equation.
prediction percentage error = (measured value - predicted value)*100/measured value
solution:
putting value in the formula
= (20-8)*100/20
= 12*5
= 60 %

Jocelyn has 3.5 yards of ribbon . she needs 0.6 yards of ribbon to make one bow. how many bows can Jocelyn make?
Answer:
[tex]5\frac{5}{6}[/tex] bows
5 whole bows
Step-by-step explanation:
[tex]\frac{0.6}{3.5}: \frac{1}{y}[/tex]
y × 0.6 = 1 × 3.5
0.6y = 3.5
0.6y ÷ 0.6 = 3.5 ÷ 0.6
[tex]y = 5\frac{5}{6}[/tex]
Answer:
Jocelyn can make 5 bows.
Step-by-step explanation:
3.5/.6 = 5.8333333
This means that Jocelyn can make 5 full bows and have a remainder of .83333333 yards of ribbon.

Factorise and solve
Solve : 3x-2 = 0
Add 2 to both sides of the equation :
3x = 2
Divide both sides of the equation by 3:
x = 2/3 = 0.667
Two solutions were found :
x = 2/3 = 0.667
x = 0

Answer:
[tex]x=\frac{2}{3}[/tex]
x = 0
Step-by-step explanation:
Method 1: Quadratic Formula
Ignore the A before the ±, it wouldn't let me type it correctly.
[tex]x=\frac{-b±\sqrt{b^{2}-4ac } }{2a}[/tex]
3x² - 2x = 0
a = 3
b = - 2
c = 0
[tex]x=\frac{-(-2)±\sqrt{(-2)^{2}-4((3)(0)) } }{2(3)}[/tex]
[tex]x=\frac{-(-2)±\sqrt{4-4((3)(0)) } }{2(3)}[/tex]
[tex]x=\frac{-(-2)±\sqrt{4+0 } }{2(3)}[/tex]
[tex]x=\frac{2±\sqrt{4 } }{2(3)}[/tex]
[tex]x=\frac{2±2 }{2(3)}[/tex]
[tex]x=\frac{2±2 }{6}[/tex]
Two separate equations
[tex]x=\frac{2+2 }{6}[/tex]
[tex]x=\frac{2-2 }{6}[/tex]
[tex]x=\frac{4 }{6}[/tex]
[tex]x=\frac{2}{3}[/tex]
[tex]x=\frac{0 }{6}[/tex]
x = 0
Method 2: Factoring
3x² - 2x = 0
(3x - 2) · x = 0
Two separate equations
3x - 2 = 0
3x - 2 + 2 = 0 + 2
3x = 2
3x ÷ 3 = 2 ÷ 3
[tex]x=\frac{2}{3}[/tex]
x = 0

What is the value of x?
45
CLEAR ALL
Given:
In triangle PQR, QS⊥PR, QS=x, PR=90 and RS=18.
To find:
The value of x.
Solution:
According to right triangle altitude theorem (geometric mean theorem), if an altitude of a right triangle divides the base into two segments then the square of altitude is equal to the product segments of the base.
Using right triangle altitude theorem, we get
[tex]\dfrac{QS}{PS}=\dfrac{RS}{QS}[/tex]
[tex]QS^2=RS\times PS[/tex]
[tex]x^2=18\times (90-18)[/tex]
[tex]x^2=18\times 72[/tex]
[tex]x^2=1296[/tex]
Taking square root on both sides, we get
[tex]x=\sqrt{1296}[/tex]
[tex]x=36[/tex]
Therefore, the correct option is B.

Answer:
-2?
Step-by-step explanation:
use y2-y1 over x2-x1 to find the answer. So you would do -2--5/3 over 4--2. The two negitives turn into a positive. SO it is now -2+5/3 over 4+2. -2+5/3= -1/3 over 4+2=6 it is now -1/3/6 which equals -2. So I think the answer is -2. I do not know if you should trust me on this but I tried.
Suppose we are interested in bidding on a piece of land and we know one other bidder isinterested. The seller announced that the highest bid in excess of $10,000 will be accepted.Assume that the competitor’s bid x is a random variable that is uniformly distributedbetween $10,000 and $15,000.a. Suppose you bid $12,000. What is the probability that your bid will be accepted?b. Suppose you bid $14,000. What is the probability that your bid will be accepted?c. What amount should you bid to maximize the probability that you get theproperty?d. Suppose you know someone who is willing to pay you $16,000 for the property. Wouldyou consider bidding less than the amount in part (c)? Why or why not?
Answer:
a. 0.4 = 40% probability that your bid will be accepted
b. 0.8 = 80% probability that your bid will be accepted.
c. $15,000.
d. Bidding $15,000 guarantees you a profit of $1,000, while trying to bid less than $15,000, you can end up without a profit, thus, you should not consider bidding less than the amount in part (c).
Step-by-step explanation:
Uniform probability distribution:
An uniform distribution has two bounds, a and b.
The probability of finding a value of at lower than x is:
[tex]P(X < x) = \frac{x - a}{b - a}[/tex]
Assume that the competitor’s bid x is a random variable that is uniformly distributed between $10,000 and $15,000.
This means that [tex]a = 10, b = 15[/tex], considering the measures in thousands of dollars.
a. Suppose you bid $12,000. What is the probability that your bid will be accepted?
Probability that the other bidder's bid is less than 12000(X < 12). So
[tex]P(X < 12) = \frac{12 - 10}{15 - 10} = \frac{2}{5} = 0.4[/tex]
0.4 = 40% probability that your bid will be accepted.
b. Suppose you bid $14,000. What is the probability that your bid will be accepted?
Probability that the other bidder's bid is less than 14000(X < 14). So
[tex]P(X < 14) = \frac{14 - 10}{15 - 10} = \frac{4}{5} = 0.8[/tex]
0.8 = 80% probability that your bid will be accepted.
c. What amount should you bid to maximize the probability that you get the property?
The upper bound of the uniform distribution, that is, $15,000.
d. Suppose you know someone who is willing to pay you $16,000 for the property. Would you consider bidding less than the amount in part (c)? Why or why not?
Bidding $15,000 guarantees you a profit of $1,000, while trying to bid less than $15,000, you can end up without a profit, thus, you should not consider bidding less than the amount in part (c).

natally needs to cut a pice of paper so that she has exactly 1/3 of it.if the length of the paper is 11 inches, how long will be the paper if she cuts . help me please
Answer:
3 [tex]\frac{2}{3}[/tex] inches long
Step-by-step explanation:
Find how long the paper will be by dividing 11 by 3. This will find how much 1/3 of the 11 inch paper is.
11/3
= 3 [tex]\frac{2}{3}[/tex]
So, if she cuts the paper, the paper will be 3 [tex]\frac{2}{3}[/tex] inches long

all the cubes root of
[tex] \sqrt{3 + i} [/tex]
If you're looking for the cube roots of √(3 + i ), you first have to decide what you mean by the square root √(…), since 3 + i is complex and therefore √(3 + i ) is multi-valued. There are 2 choices, but I'll stick with 1 of them.
First write 3 + i in polar form:
3 + i = √(3² + 1²) exp(i arctan(1/3)) = √10 exp(i arctan(1/3))
Then the 2 possible square roots are
• √(3 + i ) = ∜10 exp(i arctan(1/3)/2)
• √(3 + i ) = ∜10 exp(i (arctan(1/3)/2 + π))
and I'll take the one with the smaller argument,
√(3 + i ) = ∜10 exp(i arctan(1/3)/2)
Then the 3 cube roots of √(3 + i ) are
• ∛(√(3 + i )) = ¹²√10 exp(i arctan(1/3)/6)
• ∛(√(3 + i )) = ¹²√10 exp(i (arctan(1/3)/6 + π/3))
• ∛(√(3 + i )) = ¹²√10 exp(i (arctan(1/3)/6 + 2π/3))
On the off-chance you meant to ask about the cube roots of 3 + i, and not √(3 + i ), then these would be
• ∛(3 + i ) = ⁶√10 exp(i arctan(1/3)/3)
• ∛(3 + i ) = ⁶√10 exp(i (arctan(1/3)/3 + 2π/3))
• ∛(3 + i ) = ⁶√10 exp(i (arctan(1/3)/6 + 4π/3))
