For the equation, complete the given ordered pairs.
3x-y=4
{0,_} [1,_} {_,4}
Can someone help me
Answer:
{0,-4} [1,-1} {8/3,4}
Step-by-step explanation:
3x - y = 4
{0,_} [1,_} {_,4}
For x = 0:
3x - y = 4
0 - y = 4
y = -4
For x = 1
3x - y = 4
3 - 3 - y = 4 - 3
-y = 1
y = -1
For y=4
3x - y = 4
3x -4 = 4
3x = 8
x = 8/3
Solution:
{0,-4} [1,-1} {8/3,4}

Find 25% of 200:
Find 75% of 200:
Answer:
0
200
100
50
150
Step-by-step explanation:
0% of 200 = 0
100% of 200
= ( 100 / 100 ) x 200
= 1 x 200
= 200
50% of 200
= ( 100% of 200 ) / 2
= 200 / 2
= 100
25% of 200
= ( 50% of 200 ) / 2
= 100 / 2
= 50
75% of 200
= ( 75 / 100 ) x 200
= ( 75 x 200 ) / 100
= 75 x 2
= 150

Two friends, Chespirito and Quico, are racing down a mountain. Quico is 17.6 miles away from the Finish Line and runs 2.6 miles per hour. Chespirito is 22.8 miles from the Finish Line, but runs 3.9 miles per hour. How many hours will it take Chespirito to catch up with Quico? It will take Chespirito hours to catch up with Quico.
Answer:
4 hrs
Step-by-step explanation:
22.8-17.6=5.2
so they are 5.2 miles apart.
Let they meet after t hrs.
distance coverd by Quico in t hrs=2.6t
distance covere by Chespirito in t hrs =3.9t
3.9t-2.6 t=5.2
or 1.3 t=5.2
t=5.2/1.3 =4

slope: 10 m/srepresents speed in meters per secondStep-by-step explanation:
The slope is the change in the quantity on the vertical scale, divided by the corresponding change in the quantity on the horizontal scale.
Here, the line goes from 0 to 100 meters on the vertical scale, corresponding to a change from 0 to 10 seconds on the horizontal scale. So, the slope is ...
m = (100 m)/(10 s) = 10 m/s . . . . slope of the line
The ratio of distance to time is given the name "speed", so ...
the slope represents the sprinter's speed in meters per second.

Rewrite the following as a multiplication and use an array to write it in standard form (15m + 24) ÷ 3.
Answer:
5m + 8
Step-by-step explanation:
Dividing by 3 is the same as multiplying by 1/3.
1/3 (15m + 24)
Distribute the 1/3
1/3 * 15m = 5m
1/3 * 24 = 8
5m + 8

A rectangle has side lengths of 3 inches and square root 5 inches. Which statement
must be true
about the area of the rectangle?
Answer:
B
Step-by-step explanation:
Firstly, we will take a look at the equation and the options listed to choose from.
Secondly, we notice these options are reffering to rational and irrational numbers.
A rational number is a number that can be expressed in a ratio of 2 integers. (Form example whole numbers such as 1 (1/1), 2(2/1) 5(5/1, 10/2) and even decimals like 3.75 (375/100) or (750/200) etc.
As for irrational numbers, these can NOT be simplified between a ratio 2 integers. For example the question states 3 multiplied by the square root of 5. The square root of 5 is 2.2360679... multiplied by 3 we get 6.7082..... Numbers such as those can go on for infinity and can not be simplified as integers therefore they are irrational numbers.
.............................................................................................................
With this knowledge, it means then options A and C are out. So lets take a look at B and D which statement is true and which is false?
With this knowledge, it means then options A and C are out. So lets take a look at B and D which statement is true and which is false?B is true because we already know that the product of the numbers was 6.708.... irrational number based on our workings above.

So lets take a look at B and D which statement is true and which is false?B is true because we already know that the product of the numbers was 6.708.... irrational number based on our workings above.D is false because if the product is 6.708 it can not be the square root of 15 (3.872)
B. It is an irrational number because the product of the side lengths is [tex]3\sqrt{5}[/tex], an irrational number.
According to this question, we know the lengths of the two sides of the rectangle, the length of a side is an positive integer and the length of the other one is an positive irrational number. The area of the rectangle is the product of the two sides lengths mentioned above.
By algebra, we know that the product between an integer and an irrational number leads to other irrational number. Therefore, the area of the rectangle is represented by an irrational number.
[tex]A = (3)\cdot \sqrt{5}[/tex]
[tex]A = 3\sqrt{5}[/tex]
Hence, the right answer is B.

Answer:
Step-by-step explanation:
this is about the volume of each size of candle. so the area of the circle , times the height of the candle is the amount of wax needed or it's volume.
area of a circle is = [tex]\pi[/tex][tex]r^{2}[/tex]
then the big candle is [tex]\pi[/tex][tex]2^{2}[/tex] = 12.56637
times 10 for it's height = 125.6637
so that's the big candles volume
then make 20 of those = 2513.27
a small candle is [tex]\pi[/tex][tex]1.5^{2}[/tex] = 7.068583471
and it's 6 cm tall so times 6 = 42.41150082
Now divide the small candle volume into the 20 big ones to see how many small ones can be made
2513.27 / 42.41150082 = 59.259
so just a bit over 59 small candles can be made from 20 big candles

How to solve (x+7)(x-9)>0
9514 1404 393
Answer:
(x < -7) ∪ (x > 9)
Step-by-step explanation:
The zeros of the function are the values of x that make the factors zero.
x +7 = 0 ⇒ x = -7
x -9 = 0 ⇒ x = 9
When this is expanded, we can see that the leading coefficient is positive.
x² -2x -63 > 0
This means the parabola opens upward. It will be greater than 0 for x-values to the left of the left zero, and to the right of the right zero. (It is less than zero between those values.)
The solution is x < -7 or x > 9.
_____
In general, for polynomial inequalities, look for the locations of the zeros. The sign of the polynomial will have the sign of the leading coefficient for values of x to the right of the right-most zero. (Here, positive for x > 9.) As you progress farther to the left along the number line, the polynomial changes sign at each zero.
Here, the polynomial becomes negative between the values x=9 and x=-7. Then it is positive again for x < -7.
The residents of a certain dormitory have collected the following data: People who live in the dorm can be classified as either involved in a relationship or uninvolved. Among involved people, 15 percent experience a breakup of their relationship every month. Among uninvolved people, 30 percent enter into a relationship every month. What is the steady-state percentage of residents who are uninvolved?
Answer:
33.33%
Step-by-step explanation:
Given :
Breakup percentage = 15
New relationship percentage = 30
To obtain the steady state percentage of residents who are uninvolved, we could relate the scenario to the natural unemployment rate relation : seperation rate ÷ (seperation rate * finding rate)
Hence, we could use the Relation as this ;
Breakup percentage ÷ (Breakup percentage + new relationship rate)
15% ÷ (15% + 30%)
0.15 ÷ (0.15 + 0.30)
0.15 ÷ 0.45
= 0.33333
= 33.33%

PLEASE ASNWER ASAP WITH WORK IN A TABLE PLEASE
Answer:
Step-by-step explanation: Given is a function as 1 divided by the quantity x minus 10 squared
Mathematically translating we get
the function
Since the function become undefined at x=10 we get
vertical asymptote is
x=10
Limit x tends to 10 of f(x) will exist since both limits are equal
This is because let x tends to 0 from left.
Then we have
f(x) =
Right limit also will be +infinity
This is because the curve is symmetrical about x=10 and hence limit would be +infinity.
