Step-by-step explanation:
8x-9+2+9x=180 degree(being co interior angles)
17x-7=180
17x=180+7
x=187/17
x=11 degree
Answer:
11
Step-by-step explanation:
consecutive interior angles always equal to 180 degrees, so you would add both equations together and equal it to 180 degrees. you would then simplify and solve.
8x-9 + 2+9x = 180
-7 + 17x = 180
-7+7 180+7 = 187
17x = 187
17x/17 = 187/17
x=11

Help me please I really need it
Answer:
2
Step-by-step explanation:
To find the average rate of change, we use:
[tex]\frac{changeofy}{changeofx} =rate ofchagne[/tex]
To find this lets look at the graph.
We see that at x=2, y=-3, and at x=3, y=-1.
The change of y is the first y coordinates minus the second, which in this case is:
-3-(-1)=-2
Change is the absolute value of the 1st and 2nd y. So its really a change of 2, not -2.
Our change of x falls under the same formula, being:
2-3=-1, but really being 1.
Now to plug this into our first formula:
2/1=2
So the rate of change is 2.
This seems to be your first answer.
Hope this helps!

Answer:
-x²+8x-15
Step-by-step explanation:
There are two solutions: 3 and 5
First, let's write the equation in this form (pay attention, the parabola here is going up so it won't be like your graph):
(x-3)(x-5)
For resolve our problem, let's re-write it with a minus before:
-(x-3)(x-5)
You can also expand it and the result will be like this:

O a Olivia went to a dance party. She paid $12 as an entry fee. Once inside the dance party, she paid $2 per snack. She started the night with $30 and spent all her money.
which of the following represents an equation that could be used to model this situation?
A) 2x +12=30
B) 30+2x+12=0
C)2x -12= -30
D)30/2x =12
Answer: 2x + 12 = 30
12 is the initial fee, then x is the unknown variable. Since each snack costs 2 dollars, and we don't know how many she had, we can use the equation:
2x + 12 = 30

If f(x) = -2x - 14, then f'(x) =D
Enter the correct answer.
Answer:
f⁻¹(x) = 1/2x + 7
Step-by-step explanation:
To find the inverse of a function, simply switch x and y and solve for y once more.
f(x) = -2x - 14
x = -2y - 14
x + 14 = -2y
(x + 14)/2 = f⁻¹(x)
1/2x + 7 = f⁻¹(x)
what is the inverse of the function f(x) = 4x^3 - 9
Answer:
[tex]f(x)^-^1=\sqrt[3]{\frac{x+9}{4}}[/tex]
Step-by-step explanation:
Finding the inverse of a function is essentially doing a given function in backwards order. An easy trick to doing such is to treat the evaluation (f(x)) like a variable. Think of the function as an equation, then solve the function for (x) in terms of (f(x)).
[tex]f(x)=4x^3-9[/tex]
Inverse operations,
[tex]f(x)=4x^3-9\\\\(f(x))+9=4x^3\\\\\frac{((f(x))+9)}{4}=x^3\\\\\sqrt[3]{\frac{(f(x))+9}{4}}=x[/tex]
Now put this in the form of an inverse function, switch the places of the terms (x) and (f(x)), remember to indicate that it is an inverse function,
[tex]f(x)^-^1=\sqrt[3]{\frac{x+9}{4}}[/tex]

Which expression represents the second partial sum for Infinity Σ 3(1/2) HURRY PLEASE , I need help on a couple of them
Answer:
Step-by-step explanation:
The given expression has the first term n=1, so exponent = n-1 = 0
Similarly, for the second term n = 2, n-1 = 1
These exponents eliminate options 2 and 4.
Furthermore, the base is a fraction of 1/2, which applies to options 1 and 2 only.
The only viable option left that satisfies all conditions is option 1, which has exponents 0 and 1, with a base of (1/2).
The second partial sum for [tex]\sum\limit^\infty_{n=1}\; 3* (\frac{1}{2})^{n-1}[/tex] is [tex]3* (\frac{1}{2})^0 + 3* (\frac{1}{2})^1[/tex]
The correct option is (1)
What is Summation ?A summation, also called a sum, is the result of arithmetically adding numbers or quantities. A summation always contains a whole number of terms.
The given summation is:
[tex]\sum\limit^\infty_{n=1}\; 3* (\frac{1}{2})^{n-1}[/tex]
If we put two values of n i.e., n=1,2. hen we get the following summation series
=[tex]3* (\frac{1}{2})^{1-1} + 3* (\frac{1}{2})^{2-1}[/tex]
=[tex]3* (\frac{1}{2})^0 + 3* (\frac{1}{2})^1[/tex]
The option answer matches with the option 1.

Scott needs to get a vehicle. He decides to buy a new Ford F250. NYE Auto sells Scott the truck for $36,900. a. NYE Auto charges a destination fee of $450. They also charge $550 for a license fee. If he is also charged 8.25% of the cost of the truck for sales tax, what is the total cost of the truck to Scott?
Answer:
Car price= $36900
Sales tax 8.25%= $36900 x 8.25% = $3,044.25
Total fees= $1000
Cost of car= 36900+ 3044.25 +1000 = $40,944.25

∘
and m\angle B=(6x+17)
∘
, then find the value of x.
Answer:
x=25
Step-by-step explanation:
We know vertical angles are equal
<A = <B
7x-8 = 6x+17
Subtract 6x from each side
7x-6x-8 = 6x-6x+17
x-8 = 17
Add 8 to each side
x-8+8 = 17+8
x=25
To get a shade of blue, a painter mixes blue paint and white paint in the ratio of 4:1.
How many litres of blue paint and white paint would be needed to get 60 litres of the required
shade of blue?
Which one is correct
55 blue and 5 white
48 blue and 12 white
45 blue and 15 white
40 blue and 20 white
Answer:
48 blue and 12 white
Explanation:
60 ÷ 5 = 12
4 × 12 = 48
12L white
48L blue
To check:
48 + 12 = 60
48 liters of blue paint and 12 liters of white paint would be needed to get 60 liters of the required shade of blue.
What is ratio?"I is the comparison of two quantities of the same kind."
What is an equation?"It is a mathematical statement that consists of equal symbol between two algebraic expressions."
For given question,
To get a shade of blue, a painter mixes blue paint and white paint in the ratio of 4:1
Let 'x' be the common factor of the ratio.
[tex]\Rightarrow \frac{4}{1} = \frac{4\times x}{1\times x}[/tex]
A painter needed 60 liters of the required shade of blue.
So, we get an equation,
⇒ 4x + 1x = 60
where 4x is the amount of blue paint and 1x is the amount of white paint.
We solve above equation.
⇒ 4x + 1x = 60
⇒ 5x = 60
⇒ x = 12 liters
And the value of 4x would be,
⇒ 4x = 4 × 12
⇒ 4x = 48 liters
Therefore, 48 liters of blue paint and 12 liters of white paint would be needed to get 60 liters of the required shade of blue.

How many different committees can be formed from 12 teachers and 43 students if the committee consists of 3 teachers and 4 students?
The committee of 7 members can be selected in BLANK
different ways.
Answer:
[tex] \displaystyle 27150200[/tex]
Step-by-step explanation:
we are two conditions
committees can be formed from 12 teachers and 43 studentsthe committee consists of 3 teachers and 4 studentsIn choosing a committee, order doesn't matter; in case of teachers we need the number of combinations of 3 people chosen from 12
remember that,
[tex] \displaystyle\binom{n}{r} = \frac{n!}{r!(n - r)!} [/tex]
with the condition we obtain that,
[tex]n = 12[/tex][tex]r = 3[/tex]therefore substitute:
[tex] \displaystyle\binom{12}{3} = \frac{12!}{3!(12 - 3)!} [/tex]
simplify Parentheses:
[tex] \displaystyle\binom{12}{3} = \frac{12!}{3! \cdot9!} [/tex]
rewrite:
[tex] \rm \displaystyle\binom{12}{3} = \frac{12 \times 11 \times 10 \times 9 \times 8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1}{(1 \times 2 \times 3 )\cdot1 \times 2 \times 3 \times 4 \times 5 \times 6 \times 7 \times 8 \times 9} [/tex]
reduce fraction:
[tex] \rm \displaystyle\binom{12}{3} = \frac{12 \times 11 \times 10}{1 \times 2 \times 3 } [/tex]
rewrite 12 and 10:
[tex] \rm \displaystyle\binom{12}{3} = \frac{3 \times 2 \times 2 \times 11 \times 10}{1 \times 2 \times 3 } [/tex]
reduce fraction:
[tex] \rm \displaystyle\binom{12}{3} = 2 \times 11 \times 10[/tex]
simplify multiplication:
[tex] \rm \displaystyle\binom{12}{3} = 220[/tex]
In case of students we need the number of combinations of 4 students choosen from 43 therefore,
[tex] \displaystyle\binom{43}{4} = \frac{43!}{4!(43 - 4)!} [/tex]
simplify which yields:
[tex] \displaystyle\binom{43}{4} = 123410[/tex]
hence,
The committee of 7 members can be selected in BLANK different ways is
