2x – 9y = 14
x= -6y +7
Answer:
(7,0) ---> (x = 7) and (y = 0)
Step-by-step explanation:
2x – 9y = 14
x= -6y +7 <-- (Substitute for x to above equation)
---------------------------------------------------------------------------------------------------------
2(-6y +7)– 9y = 14
-12y + 14 - 9y = 14 <-- combine like terms
-21y + 14 = 14
-14 = -14 <-- inverse operation on both sides
-21y = 0 <-- Divide
y = 0 <--- Substitute for y to get x ↓
-------------------------------------------------------------------------------------------------------
2x – 9y = 14
2x – 9(0) = 14 <-- Substituted y from above
2x = 14 <-- Divide
x = 7
Does this graph show a function? Explain how you know.
Answer:
C
Step-by-step explanation:
It passes the vertical line test
the vertical line test is taking a vertical line and putting it anywhere on the graph, and if it passes 2 points, it fails, and since if you put the line anywhere, it only passes one point of the parabala, so it passes the line test
Answer: C
Step-by-step explanation: The easiest way to determine if a
relation is a function is to use the vertical line test.
The vertical line test tells us that if we can draw a vertical line
that intersects more than one point on the graph of a relation,
then the relation is not a function.
However, in this case, notice that there is no way to draw a
vertical line that intersects more than one point on the graph.
Therefore, this relation must be a function.

Solve for m: 3m2 + 30m – 168 = 0.
Step-by-step explanation:
On simplifying its
M2 + 10m - 56 = 0.......... (divide both side by 3)
M2 - 4m + 14m - 56=0
M(M-4) + 14(m-4) =0
(M+14) + (m-4)=0
M =4, - 14.
If the condition is given that you cannot put m's value negative. Than the answer is M=5....
THANKU
Answer:
m = 4
m = -14
Step-by-step explanation:
here's your solution
=> 3m^2 + 30m - 168
=> firstly we will make it in simplest form
=> take 3 common
=> 3(m^2 + 10m - 56)
=> we get , (m^2 + 10m - 56)
=> now, factories it by using middle term split
=> m^2 + 14m - 4m - 56
=> now take common
=> m(m + 14) - 4(m + 14)
=> (m - 4) (m + 14)
=> m - 4 = 0
=> m= 4
=> (m+14) =0
=> m = -14
There are 45 students in a school play. 3/5 of the students are preforming and the remainder of students are pert of the backstage crew.
Answer:
Assuming the question is: How many students are performing:
There are 45 students. The number of students performing is 3/5 of this total number of students.
This number is actual figures is:
= 3/5 * 45
= 27 students
The number of students in the backstage crew is therefore:
= 45 - 27

Help ASAP I’ll mark you as brainlister
Answer:
Step-by-step explanation:
1. I can't see the first one very well.
2. Find the area of each triangle by doing 1/2 * base * height. This should give you [tex]40m^{2}[/tex]
3. The area of a trapezium is [tex]\frac{1}{2} (a+b)h[/tex] where a is the top edge, b is the bottom edge and h is the height.
We can work out the bottom edge using pythagoras - split the trapezium into 2 triangles on each side and a rectangle in the middle. This gives you the length of the bottom edge which is 2 + 2 + 2 = 6'
Work out the area by doing 1/2(2+6)4 = 16' squared.
4.Split this shape into a triangle and rectangle. We know the right hand edge of the triangle= 9-4 = 5'.
To find the bottom edge of the triangle, use tanθ=opposite/adjacent line. Therefore tan45=bottom edge of triangle/5'. tan 45=1 therefore bottom edge = 5'.
The bottom edge of triangle gives us the height; use 1/2(a+b)h to work out the area of the trapezium. 1/2(4+9)5 = 32.5' squared
A vacation resort offers surfing lessons and parasailing. If a
person takes a surfing lesson and goes parasailing, she will pay
a total of $175. On Friday, the resort collects a total of $3,101 for
activities. How much does each activity cost?
After solving the equations, the cost of parasailing will be 99.75 and the cost of surfing will be equal to 75.25.
What is an Expression?Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both.
Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.
The given information in the question is,
Assume the cost of parasailing is x and the cost of surfing is y.
x + y = 175
Total number of people in Parasailing = 16 people
Total number of people in Surfing = 20 people
Total collection done by resort = $3,101
16x + 20y = 3,101
So, the equations will be,
16x+20y=3,101 (i)
x + y = 175 (ii)
Now, multiply the equation (ii) by 16 and solve the equation,
16x+20y=3,101
16x+16y= 2,800
4y = 301
Now, find the value of y,
y = 301/4
y = 75.25
Then, the value of x will be equal to,
x + y = 175
x+75.25 =175
Solve for x:
x=175-72.25
x = 99.75

My three cars can travel the same distance on a tank of gas. My second car gets 6 kilometers per liter more than
my first, but its tank holds 3 fewer liters than my first. My third car gets 6 kilometers per liter less than my first, but its tank holds 6 more liters
than my first. How many kilometers can each car travel on a tank of gas?
Answer:
16
Step-by-step explanation::
wrote on NEML, got it right,
Distance traveled by an car is the ratio of the mileage gives by the car to the total fuel the tank holds. The millage of 6 kilometre per liter in 3 liter the cars can travel 18 kilometre.
Given information
All three cars can travel the same distance on a tank of gas.
The second car gets 6 kilometres per liter more than the first, but its tank holds 3 fewer liters than the first.
The third car gets 6 kilometres per liter less than the first, but its tank holds 6 more liters than the first.
Suppose the first car runs m. kilometre per liter. Then the second car will run (m+6) kilometre per liter and third car runs (m-3) kilometre per liter.
Suppose the first car has l liter in the tank. Then the second car has (l-3) liter and third car has (l+6) liters in her tank.
DistanceDistance traveled by an car is the ratio of the mileage gives by the car to the total fuel the tank holds.
As the distance traveled by the first car is same as the second one. Hence,
[tex]\begin{aligned}\\\dfrac{m}{l} &=\dfrac{m+6}{l-3} \\ml-3m&=ml+6l\\m&=-2l\\\end[/tex]
Let the above equation is equation 1.
As the distance traveled by the second car is same as the third one. Hence,
[tex]\begin{aligned}\\\dfrac{m-3}{l+6} &=\dfrac{m+6}{l-3} \\ml-3m+9-3l&=ml+6l+6m+36\\l+m&=-3\\\end[/tex]
Put the value of m in the above equation from equation 1,
[tex]l-2l=-3\\l=3[/tex]
[tex]m=2\times3=6[/tex]
Thus the value of the m is 6.
With the millage of 6 kilometre per liter in 3 liter the cars can travel 18 kilometre.

The isotope Herodium-100 decreases by half every minute, Herodium-100 is there
isotope that gives a super hero their strength. Once the amount depletes to 4 ml, a
superhero becomes tired and need to leave the fight. If Mathman has 2000mL in his
body, when will he have to rest and replenish, rounded to the nearest minute?
Answer:
After about 9 minutes.
Step-by-step explanation:
We can write an exponential function to model the decay of Herodium-100.
We are given that it decreases by half every minute.
The standard exponential function is given by:
[tex]f(m)=A(r)^m[/tex]
Where A is the initial amount, r is the rate, and m is the rate (in this case, in minutes).
Mathman initially has 2000 mL of Herodium-100. Therefore, A = 2000.
And since it decreases by half every minute, r = 1/2. Thus:
[tex]\displaystyle f(m)=2000\Big(\frac{1}{2}\Big)^m[/tex]
Mathman needs to rest when the Herodium-100 levels drop to 4 mL. Therefore, we can substitute 4 for f(m) and solve for m:
[tex]\displaystyle 4=2000\Big(\frac{1}{2}\Big)^m[/tex]
Solve for m. Divide both sides by 2000:
[tex]\displaystyle \frac{4}{2000}=\frac{1}{500}=\Big(\frac{1}{2}\Big)^m[/tex]
We can take the natural log of both sides:
[tex]\displaystyle \ln\Big(\frac{1}{500}\Big)=\ln\Big(\frac{1}{2}^m\Big)[/tex]
By logarithm properties:
[tex]\displaystyle \ln\Big(\frac{1}{500}\Big)=m\ln\Big(\frac{1}{2}\Big)[/tex]
Therefore:
[tex]\displaystyle m=\frac{\ln(1/500)}{\ln(1/2)}\approx 8.9657\approx 9\text{ minutes}[/tex]
Mathman will have to rest and replenish after 9 minutes.
