Answer:
(2, -1)Step-by-step explanation:
Given system
18x+6y=30 18x+22y=14Solve by elimination, subtract the equations and solve for y:
18x + 6y - 18x - 22y = 30 - 14-16y = 16y = -1Find x by substituting y:
18x + 6(-1) = 3018x - 6 = 3018x = 36x = 36/18x = 2The answer is: (2, -1)

Answer:
C. The y-intercepts of the two functions are opposites.
Step-by-step explanation:
The y-intercept of g(x) is -1 and the y-intercept of h(x) is 1. -1 and 1 are opposites, so the two y-intercepts are also opposites.

36 - 7p = -7 ( p - 5)
a) No Solution
b) One Solution
c) Infinite Solutions
Answer:
a) No Solution
Step-by-step explanation:
36 - 7p = -7(p - 5)
36 - 7p = -7p + 35
1 - 7p = -7p
1 = 0p
so a) No Solution
Answer:
[tex]36 - 7p = - 7(p - 5) \\ 36 - 7p = - 7p - 7 \times - 5 \\36 - 7p = - 7p + 35 \\ p \: terms \: togather \\ - 7p + 7p = 35 - 36 \\ 0p = - 1 \\ here \: we \: \: have \: 0p \\ so \: no \: solution \\ option(a) \\ thank \: you[/tex]

Answer:A
Step-by-step explanation:
The Jayden family eats at a restaurant that is having a 15% discount promotion. Their meal
costs $78.86 before the discount, and they leave a 20% tip. If the tip applies to the cost of
the meal before the discount, what is the total cost of the meal? Round your intermediate
calculations and answer to the nearest cent.
Answer: $80.44
Step-by-step explanation:
First of all, find 20% of 78.86, which is approximately 15.77.
Then, add it to the cost of the meal.
Finally, discount 15% of 94.63, which is approximately $14.19, and then subtract it from $94.63, and there's your answer.

Answer:
quintic polynomial
Step-by-step explanation:
it depends on the degree and the degree is at 5 so its quintic quin means 5
Answer:
It is a Quintic Polynomial
Step-by-step explanation:
When classifying polynomials, there is usually a list that you should get that makes classifying easier.
I put the list down below.
In order to find if it is constant (0), linear (1), quadratic (2), cubic (3), quartic (4), or quintic (5), look at the exponent with the highest value (0 through 5), and it will give you the name. So in the equation, you have above, the highest exponent is 5. So this is a quintic.
In order to find the next part of the expression, monomial, binomial, trinomial, and polynomial, look at how many terms there are in the expression. There are 4 terms, so this a polynomial.

A student tries to solve the equation 2(x-7)+x-9. The student work is shown to the right describe the errors. Then solve the equation correctly
Answer: 3x - 23
Step-by-step explanation:
To solve the equation goes thus:
= 2(x-7)+x-9.
We have to open the bracket first
= 2x - 14 + x - 9
We then collect like terms
= 2x + x - 14 - 9
= 3x - 23
Therefore, the answer is 3x - 23

Which type of transformation is described by (x, y) + (x+2, y+3)?
(А)
a translation 2 units to the right and 3 units down
(В
a translation 2 units to the left and 3 units down
a translation 2 units to the right and 3 units up
D
a translation 2 units to the left and 3 units up
(x, y) → (x+2, y+3) means a translation 2 units to the right and 3 units up.
What is transformation?Transformations are changes done in the shapes on a coordinate plane by rotation, reflection or translation.
here, we have,
Given the rule of transformation:
(x, y) → (x+2, y+3)
If we move horizontally 2 units to the right, 2 is added to the x-coordinate of any given point, and then 3 units up.
In other words,
(x, y) → (x+2, y+3) means Translation 2 units right and 3 units up.
For example,
Let say if we have the point A(4, 5)
Using the translation rule:
(x, y) → (x+2, y+3)
A(4, 5) → A'(4 + 2, 5 + 3) → A'(6, 8)
Therefore, the new position of A(4, 5) after translating 3 units right and 2 units up would be: A'(6,8).
Hence, (x, y) → (x+2, y+3) means a translation 2 units to the right and 3 units up.

Complete question :
Scottie is standing next to a lighthouse on the edge of a cliff overlooking the ocean. The cliff is 30 meters above
sea level, and the lighthouse has a height of 15 meters. There is a man fishing in a boat directly below Scottie who
has hooked a fish that is 10 meters below the surface of the water.
a. Use positive and negative numbers to represent the locations in relation to sea level.
Scottie =
Top of the lighthouse =
The boat =
The fish =
meters
b. How far is Scottie from the fish?
Answer:
30 m ;
15 m ;
0 m;
40 m
Step-by-step explanation:
Scottie's position = standing on cliff
Height of cliff = 30 m above sea level
Height of lighthouse = 15 meters
Position of fish = 10m below sea level
Above sea level = positive, +
Below sea level = negative, -
Scottie's position = 30 m
Top of lighthouse = 15m
BOAT = surface of sea = 0m
Fish = - 10 m
Distance of Scottie from fish :
Scottie's position - Position of fish
30m - (-10)m
30m + 10m
= 40m
70 of the rooms in a hotel are full if the hotel is 87.5% full then how many total rooms are there at this hotel
Answer:
80 rooms
Step-by-step explanation:
Given: 70 of the rooms in a hotel are full such that the hotel is 87.5% full.
To find: total number of rooms in the hotel
Solution:
Number of filled rooms [tex]=70[/tex]
Percentage if filled rooms [tex]=87.5\%[/tex]
Let [tex]x[/tex] denotes total number of rooms.
Therefore,
[tex]\frac{87.5}{100}x=70\\\\x= 70(\frac{100}{87.5} )\\\\x=80[/tex]
So, there are [tex]80[/tex] rooms in the hotel.

-0.1 = -10c who can answer this
Answer:
c = 0.01 | Hope I helped :')
Steps to answer:
1. Divide both sides by -10.
-0.1/-10=c
2. Simplify -0.1/-10 to 0.01.
0.01=c
3 Switch sides.
c=0.01
---------------
Checking your answer:
−0.1=−10c
1 Let c=0.01.
−0.1=−10×0.01
2 Simplify 10×0.01 to 0.1.
-0.1=-0.1

Step-by-step explanation:
Avery walked for 0.25 miles in 5 minutes. Then she stopped for 5 minutes to meet her friend.After that both of them walked 0.75 miles in 15 minutes.
Again this option is also correct.
Avery walked for 5 minutes at a pace of 20 minutes per mile. Then she stopped for 5 minutes to meet her friend.After that both of them walked for 15 minutes at a pace of 20 minutes per mile.
Because, Time taken to travel 1 mile is 20 minutes.
So, time taken to travel 0.25 miles = 20 * 0.25 = 5 minutes
Time taken to travel 0.75 miles = 20 * 0.75 = 15 minutes
One angle of a right triangle measures 34°. What is the measure of the other acute angle?
Answer:
Step-by-step explanation: one has to be 90 degrees, so 34 plus 90. The angles of a triangle always add up to 180 so, subtract the answer of 34 plus 90 from 80 and you should get the answer.

What is the value of 6x+7y−5 when x = 2 and y = 3?
Answer:
28
Step-by-step explanation:
6(2) + 7(3) - 5
12 + 21 -5
It's a good idea to get into the habit of using parenthses
when substituting numbers in for variables.
Since x = 2 and y = 3, 6x + 7y - 5 is 6(2) + 7(3) - 5.
Simplifying from here, we get 12 + 21 - 5 or 33 - 5 which is 28.
