find the next terms for this equation
Answer:
The next 4 terms are -2.4, -8, - 13.6, 19.2.
Step-by-step explanation:
u1 = u0 - 5.6
= 3.2 - 5.6
= -2.4.
u2 = u1 - 5.6
= -2.4 - 5.6
= -8.
Solve the system below. Then find −2xy.
x=−11−4y
2x−3y=11
Answer:
- 2xy = 6
Step-by-step explanation:
x = - 11 - 4y → (1)
2x - 3y = 11 → (2)
Substitute x = - 11 - 4y into (2)
2(- 11 - 4y) - 3y = 11 ← distribute parenthesis and simplify left side
- 22 - 8y - 3y = 11
- 22 - 11y = 11 ( add 22 to both sides )
- 11y = 33 ( divide both sides by - 11 )
y = - 3
Substitute y = - 3 into (1)
x = - 11 - 4(- 3) = - 11 + 12 = 1
solution is (1, - 3 )
Then
- 2xy = - 2 × 1 × - 3 = 6

Answer:
-2
Step-by-step explanation:
From the graph, it appears that (0, 2) and (2, -2) are points on the line. (Othere points will work, as well; you just need two points.)
Slope = (difference between the y coordinates) / (difference between the x coordinates)
One phrase to remember this is slope = "rise over run" (vertical change divided by horizontal change from point to point).
Slope = (-2 - 2) / (2 - 0) = -4 / 2 = -2
The slope is -2.

Which table could be a partial set of values for a linear function? PLEASE HELP I WILL MARK BRAINLIEST!!!
Answer:
3rd option, bottom left
3, 5, 7, 9
Step-by-step explanation:
In a linear function, every step in x has to have an equal step in y.
1.
9 to 8 = -1
8 to 5 = -3
5 to 0 = -5
The steps chance in size, so this cannot be a linear function.
2.
1 to 2 = 1
2 to 5 = 3
5 to 10 = 5
This is also not a linear function.
3.
3 to 5 = 2
5 to 7 = 2
7 to 9 = 2
This one could be a linear function.
4.
I already got the answer above and this one is clearly not linear so I won't write it out.

Explanation:
Inequalities are solved just like regular equations. The difference is that you need to take care to reverse the direction when multiplying or dividing negative numbers.
The simplest way to solve an inequality is to first solve it as an equality, and then CHECK the value to find out which way the sign should point.

Answer:
the probability of drawing a green marble is 4/25 (16% or 0.16)
Step-by-step explanation:
Total: 16+8+9+12+5= 50
# of green marbles: 8
Event G, such that a green marble is drawn:
P(G)= 8/50

You are the owner of a horse stable in Brownsville, TN. The stables charge $25 to ride a horse for 1 hour. You have to pay $75 per day for the horse feed and $0 per day for a safety inspection. If you want to make a profit of at least $500, each day, what is the minimum number of rides you must give? Write an inequality that can be used to find the minimum number of rides, r, which must give each day to make the daily profit. Round your first answer to the nearest tenth, then write the total number of rides you must give each day to make the profit. e.g. 210.8, 211 people

Answer:
Y = -1/2 x
Step-by-step explanation:
To write the equation in slope intercept form
Y = mx + c
C is y-intercept
the graph is passing through centre. That means y-intercept is zero.
so C=0
To find m which is slope,
[tex] \frac{rise}{run} [/tex]
rise = 10
run= -20
[tex] \frac{10}{ - 20} \\ \frac{ - 1}{2} [/tex]

what is number 11. solve for x
Answer:
Step-by-step explanation:
okay so the equation is 3x - 12 = 78
add 12 on both sides
3x = 90
divide both sides by 3
x = 30
Answer:
The missing value (x) is 12.
Step-by-step explanation:
Given that there are two values already known, 78° and 78°, we can add them and get 156°.
Since a triangle has a total degree of 180°, we can do this:
180°-156° = 24°
So, now we have the missing angle and its equal to 24°.
what you now do is set 24°= 3x-12 to solve for x.
24°=3x-12
36=3x
/3
12=x

Answer:

Step-by-step explanation:
pls mark brainliest! have a lovely day
The cost of one lolly is 0.5.
What is equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have LHS = RHS (left hand side = right hand side) in every mathematical equation. To determine the value of an unknown variable that represents an unknown quantity, equations can be solved. A statement is not an equation if it has no "equal to" sign.
Given:
Kate buys 2 lollies and 5 chocices for £6.50
Pete buys 2 lollies and 3 chocices for £4.30
let the price for lollies be 'x' and price for chocices be 'y'
So,
2x + 5y = 6.50
2x + 3y = 4.30
Now, solving the above equation
2y = 2.2
y= 1.1
and, x= 1/2 = 0.5
Hence, cost of one lolly is 0.5.

triangle ABC has vertices A(3,1) B(4,5) C(2,3) rotate triangle ABC 90° counterclockwise about the origin and then reflect it across the x-axis
Using translation concepts, the vertices will be given as follows:
A'(-1,-3), B'(-5,-4), C'(-3,-2).
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
The rule for a 90º counterclockwise rotation about the origin is:
(x,y) -> (-y,x).
Hence:
A': (3,1) -> (-1,3).B': (4,5) -> (-5,4).C': (2,3) -> (-3,2).The rule for a reflection across the x-axis is:
(x,y) -> (x,-y).
Hence:
A': (-1,3) -> (-1,-3).B': (-5,4) -> (-5,-4).C': (-3,-2) -> (-3,-2).The vertices are:
A'(-1,-3), B'(-5,-4), C'(-3,-2).

Aplicando el mínimo común múltiplo, se encuentra que el sonido de las dos campanas volverá a coincidir en 180 minutos.
La campana mayor suena a cada hora, o sea, a cada 60 minutos.La campana menor suena a cada 45 minutos.Para ver cuando ambas le van a suenar al mismo tiempo, se calcula el mínimum común múltiplo de los intervalos, o sea, de 60 y 45.

Helllp. A total of 510 tickets were sold for the school play. The number of student tickets sold was four times the number of adult tickets. How many adult tickets were sold?
Answer:
102 tickets
Step-by-step explanation:
x=student
y=adult
x=4y
510=x+y
510=4y+y
510=5y
102=y
There are 102 adult tickets were sold.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
A total of 510 tickets were sold for the school play.
And, The number of student tickets sold was four times the number of adult tickets.
Now,
Let number of adult tickets = x
So, The number of student tickets = 4x
Here, A total of 510 tickets were sold for the school play.
So, We can formulate;
⇒ x + 4x = 510
Solve for x as;
⇒ 5x = 510
⇒ x = 102
Thus, There are 102 adult tickets were sold.
