Which ordered pair would form a proportional relationship with the point graphed below? 40 (-20,40) 30 20 10 -40-30-20-190 10 20 30 40 x -20 -30 -40 0 (-40, 20) 0 (-10.-20) O (15, -30) O (5, -15)
Answer:
(15,-30)
Step-by-step explanation:
By forming a proportional relationship with the marked point, what we are saying is that the same dilation if applied to each coordinates of the marked point will form the new point
The marked point is given as (-20,40)
If we dilate this by -0.75 units
That will give (15, -30)
So this forms a proportional relationship with the marked point

Answer:
Answer is 159
Step-by-step explanation:
Use PEMDAS
First, solve paranthesis
10² + 8² - 5
Then from left to right, solve the exponents
100 + 8² - 5
100 + 64 - 5
Then, add
164 - 5
Subtract
159
Answer:
=159
Step-by-step explanation:
10^2 + (3+5)^2 - 5
10^2 = 10 x 10 = 100
100+ (3+5) (3+5) - 5
100+(8)(8)-5
100+64-5
164-5
=159

frankie can build a speaker box in 120 minutes trash can build a speaker box 40 minutes faster if they work together how many minutes does it take them to build the speaker box
9514 1404 393
Answer:
48 minutes
Step-by-step explanation:
Each minute, F can build 1/120 of a speaker box, and T can build 1/80 of a speaker box. Working together, in 1 minute, they can complete ...
1/120 + 1/80 . . . . . speaker boxes
= 2/240 +3/240 = 5/240 = 1/48 . . . . speaker boxes
Then there will be 1 complete speaker box after 48 minutes.
Write an equation for the nth term of the arithmetic sequence.
2, 5, 8, 11, ...
Answer:
An equation for the nth term of the arithmetic sequence.
[tex]a_n=3n-1[/tex]
Step-by-step explanation:
Given the sequence
2,5,8,11,...
An arithmetic sequence has a constant difference 'd' and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
here
a₁ = 2computing the differences of all the adjacent terms
d = 5-2 = 3, d = 8-5=3, d=11-8=3Using the nth term formula
[tex]a_n=a_1+\left(n-1\right)d[/tex]
substituting a₁ = 2, d = 3
[tex]a_n=2+\left(n-1\right)3[/tex]
[tex]=2+3n-3[/tex]
[tex]=3n-1[/tex]
Thus, an equation for the nth term of the arithmetic sequence.
[tex]a_n=3n-1[/tex]

if ab=5 and a²+b²=25,then (a+b)² equals to.
Answer:
30
Step-by-step explanation:
Given
ab=5
a²+b²=25
So
(a+b)²=a²+ab+b²
=a²+b²+ab
=25+5
=30
Answer:
(a + b)² = 35
Step-by-step explanation:
Note the expansion of (a + b)²
(a + b)² = a² + b² + 2ab ← substitute given values
= 25 + 2(5)
= 25 + 10
= 35

If you are buying at item at a store for a price of $61, and there is a 6.7% tax added on top, what would be the total amount due at the register, to the nearest cent?
Answer:
The total amount due at the register will be: $65.09
Step-by-step explanation:
The cost of an item = $61
tax on item = 6.7%
The tax amount = 6.7% × 61
= 0.067 × 61
= $ 4.09
The total cost = cost of an item + tax amount
= $61 + $4.09
= $65.09
Therefore, the total amount due at the register will be: $65.09

O A. (-1,2)
OB. (-2,4)
O C. (2, -1)
O D. (4,-2)
Answer:
it is B
Step-by-step explanation:
Look at where both of the lines meet from there you can find that (-2,4) is the solution
The solution to the system of equations is (x, y) = (-2, 4).
Option B is the correct answer.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
We can solve this system of equations by setting the expressions for y equal to each other and solving for x, then substituting the value of x into one of the equations to find the corresponding value of y.
y = x + 6 ...(1)
y = -0.5x + 3 ...(2)
Setting equations (1) and (2) equal to each other gives:
x + 6 = -0.5x + 3
Solving for x, we get:
x + 0.5x = 3 - 6
1.5x = -3
x = -2
Substituting x = -2 into equation (1), we get:
y = -2 + 6
y = 4
Therefore,
The solution to the system of equations is (x, y) = (-2, 4).

A scuba diver is swimming in the ocean 10 feet below sea level. Then, she dives down 12 more feet to get a better look at a coral reef.
Complete question :
A scuba diver is swimming in the ocean 10 feet below sea level. Then, she dives down 12
more feet to get a better look at a coral reef.
What is the scuba diver's final position relative to sea level?
Answer:
- 22 feets
Step-by-step explanation:
Given that:
Starting position of scuba diver = 10 feets below sea level = - 10 feets
Then a further descent of 12 feets in other to get a better look of the coral Reef
Further descent = - 12 feets (below sealevel)
Hence, Final position of the scuba diver will be:
Starting position + depth of further descent
(-10 + - 12) feets
-22 feets

A temperature increase of 1 degree Celsius is equivalent to a temperature increase of 1.8 degrees Fahrenheit.
A temperature increase of
5
9
degree Fahrenheit is equivalent to a temperature increase of 1 degree Celsius.
A) I only
B) II only
C) III only
D) I and II only
Answer:
The final answer is D) I and II only
Step-by-step explanation:
Think bout what the formula is
y=mx+b
in this case
the slope of the graph is
5/ 9 , which means that for an increase of 1.
C= 5 /9 (F)
C=
5 /9 (1)= 5 /9
Therefore, statement I is true. This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of
9 /5 degrees Fahrenheit.
Statement II is also true since only answer that has both statement I and statement II as true is D, is not true since 25/81 not 1 degree.

Answer:
[tex]A_2=128.69\ in^2[/tex]
Step-by-step explanation:
The area of a circle varies directly as the square of its radius.
[tex]A=\pi r^2[/tex]
If r₁ = 2in, A₁ = 12.568 in₂, r₂ = 6.4 in, A₂ = ?
ATQ,
[tex]\dfrac{A_1}{A_2}=\dfrac{r_1^2}{r_2^2}\\\\A_2=\dfrac{A_1r_2^2}{r_1^2}\\\\A_2=\dfrac{12.568 \times 6.4^2}{2^2}\\\\=128.69\ in^2[/tex]
So, the new area of the circle is [tex]128.69\ in^2[/tex].
