Function NotationThe y-intercept is the y value when x = 0. Another way to reword that is when the graph crosses the y-axis.Step-by-step explanation:
Step 1: Define
f(x) = x² - 8x + 15
Step 2: Find y-intercept
Substitute x = 0: f(0) = 0² - 8(0) + 15Exponents: f(0) = 0 - 8(0) + 15Multiply: f(0) = 0 + 15Add: f(0) = 15Rewrite: (0, 15)The nth term of a sequence is 8-n

f(x) = 16* and
19(x) = 161/2
related?
Answer:
F(x) = 16^x = 8^2x
g(x) = 16^1/2x = 8^x
So you can see the relationship. They are all of the type a^bx form, with same base of a, f(x) will have larger increasing rate.

what is the equation of a line perpendicular to 2x-3y=6 and passes through the point (6,-1) ?
Answer:
y=-3/2x+8
Step-by-step explanation:
Alright so first we need to convert this equation to Y=mx+b form.
We get y=2/3x-2
In order for it to be perpendicular, we must use -3/2 as the slope.
y=-3/2x+b
Next we need to find the y-intercept of this
Plug in 6 for x and -1 for y and solve for b
b=8

8/11 x (5/9 - 1/6) ÷ 1 5/9
Answer:
28/165
Step-by-step explanation:
You always use the order of operations, and the order of operations says to solve parentheses first, so you would solve 5/9 - 1/6, and get 7/18.
You would do exponents next, if there were any, but there is not, so you move on to the next operation(s).
The next operations are multiplication and division. From left to right, multiplication is first, so you solve 8/11 x 7/18 and get 28/99. Then, there is a division problem to solve. The problem is 28/99 ÷ 15/9. If you solve that correctly, you will get the answer 28/165.
The next step would be to simplify 28/165, but it cannot be simplified, so you are left with the answer 28/165.

Answer:
20
Step-by-step explanation:
because angle 5 is found on the same line as 45 degrees (don't remember what that's called), we can subtract from 180 to find
angle 5 = 135
angle 5 and 5x+35 are alternate interior angles, so they have the same value
135=5x+35
100=5x
20=x

-5(n-1)=7(n+3)
Solve for the missing variable please help!
Answer:
n = - [tex]\frac{4}{3}[/tex]
Step-by-step explanation:
Given
- 5(n - 1) = 7(n + 3) ← distribute parenthesis on both sides
- 5n + 5 = 7n + 21 ( subtract 7n from both sides )
- 12n + 5 = 21 ( subtract 5 from both sides )
- 12n = 16 ( divide both sides by - 12 )
n = [tex]\frac{16}{-12}[/tex] = - [tex]\frac{4}{3}[/tex]
Answer:
Step-by-step explanation:
To solve this you have to use the distributive property.
So first you would distribute the -5 to n and -1.
So the new equation will be -5n + 1 = 7 (n + 3)
Next, distribute the 7 to n and 3.
The new equation will be -5n + 1 = 7n + 21
Next you simplify by adding 5n to both sides which will give you 1 = 12n + 21
Then you subtract 21 from both sides and get -20 = 12n
So then you divide both sides by 12 to get n by itself and you are left with -5/3 = n

a 20% sugar syrup is mixed with 10% sugar syrup.The result is 600 g of 12% sugar syrup. How many grams of each syrup are in the mixture.
Answer:
120 grams of 20% sugar and 480 grams of 10% sugar
Step-by-step explanation:
The reason that the answer is what it is is because the total of the sugar syrup must be 600 grams. It is 12% which means that its 1/5 20% and 4/5 10% and if you divide 600 by 5 you get 120 therefore 120 grams of 20% sugar is correct and for the rest just subtract 120 from 600 the get the answer.
There are 120 g of 20% sugar syrup and 480 grams of 10% of sugar syrup.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
A 20% sugar syrup is mixed with 10% sugar syrup.
And, The result is 600 g of 12% sugar syrup.
Now,
It is 12% which means that its 1/5 of 20%.
Hence, Amount of sugar grams = 600 / 5
= 120 grams
And, It is 12% which means that its 4/5 of 10%.
Hence, Amount of sugar grams = 600 / (4/5)
= 480 grams

Deb is searching online for airline tickets. Two weeks ago, the cost to fly from Hartford to Boston was
$210. Now the cost is $335. What is the percent increase? What would be the percent increase if the
airline charges an additional $50 baggage fee with the new ticket price?
The percent increase of the airline ticket is %.
(Round to the nearest percent as needed.)
Answer:
Percent increase = 60%
Percent increase with baggage = 83%
Step-by-step explanation:
Given that:
Old price of the ticket = $210
New price of the ticket = $335
Increase amount =335-210 = $125
Percent increase = [tex]\frac{Inrease\ amount}{Old\ price}*100[/tex]
Percent increase = [tex]\frac{125}{210}*100 = 0.595*100[/tex]
Percent increase = 59.52% = 60%
Additional charges = $125+$50 = $175
Percent increase = [tex]\frac{175}{210}*100[/tex]
Percent increase = 83%
Hence,
Percent increase = 60%
Percent increase with baggage = 83%

Solve the system of linear equations. Y=-1/6x+5 and x+6y=30 Can you explain the steps?
Answer:
Infinitely many solutions
Step-by-step explanation:
y = -1/6x + 5
x + 6y = 30
We can solve this system by using substitution or elimination. Since we are given an isolated y-value, I'll be using the substitution method.
Substitute y = -1/6x + 5 into the second equation for y.
x + 6(-1/6x + 5) = 30Distribute 6 inside the parentheses.
x - x + 30 = 30Combine like terms.
30 = 30Since this is a true statement, we can conclude that this system has a solution of all real numbers, or infinitely many solutions.
We can also see that these equations are indeed equivalent by multiplying the top equation by 6.
6 * (y = -1/6x + 5) → 6y = -x + 30
Adding x to both sides and rearranging terms gives us x + 6y = 30, which is the same as the second equation.

An art teacher has a total of 5/8 pound of clay.The teacher puts 1/32 pound of clay at each work station.How many total work station will the art teacher be able to set up
Answer: Total work stations = 20
Step-by-step explanation:
Total clay = [tex]\dfrac58[/tex] pound
Clay at each work station = [tex]\dfrac1{32}[/tex] pound
Total work stations = (Total clay ) ÷ (Clay at each work station )
[tex]=\dfrac58\div\dfrac{1}{32}\\\\=\dfrac58\times32\\\\= 5\times4\\\\= 20[/tex]
