Hello, My Shining Love
3 erasers cost $4.41
What equation would help determine the cost of 4
erasers?
Answer:
Well you can divide 4.41 by 3 and then use that number and multiply it by 4
Step-by-step explanation:
Answer:
Using this equation: f(x) = 1.47x
The cost of 4 erasers is 5.88
each costs 1.47
f(x) = 4x + 7
f(8) = 11
I'm not sure exactly what you're trying to ask, but this statement is not true.
to solve a function, you would input a number ,and in this example 8, and replace the x's with 8.
f(8)=4(8)+7
f(8)=32+7
f(8)=39, so when you input 8, your output is 39, not 11.
the function is linear.
Can somebody help me in these questions? Will be marked as brainlest! :)
Answer:
2. A(n) = 8+(n-1)-6
3. (-3-(-4))/(-6-8)
= -1/14
Answer:
see explanation
Step-by-step explanation:
(2)
The explicit formula for an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 8 and d = a₂ - a₁ = 2 - 8 = - 6 , thus
[tex]a_{n}[/tex] = 8 - 6(n - 1) = 8 - 6n + 6 = 14 - 6n
(3)
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (8, - 4) and (x₂, y₂ ) = (- 6, - 3)
m = [tex]\frac{-3+4}{-6-8}[/tex] = [tex]\frac{1}{-14}[/tex] = - [tex]\frac{1}{14}[/tex]
please hurry Solve: -23 = x - 23 *
Answer:

substitute x for 0, and the equation is still correct
It takes 404040 ink cartridges and 200200200 pages to print a book, and it takes 303030 ink cartridges and 808080 pages to print a magazine. Sarah wants to print books and magazines with at most 300300300 ink cartridges and 120012001200 pages. Let BBB denote the number of books she prints and MMM the number of magazines she prints.
Answer:
40B +30M ≤ 300
200B +80M ≤ 1200
Step-by-step explanation:
The inequality functions are as follows:
For 40 cartridges per book and 30 cartridges per magazine and at most 300 cartridges are used
So the function would be
40B +30M ≤ 300
Now the another would be
There are 200 pages for printing a book and 80 pages are required for printing a magazine also she used at most 1,200 pages
So, the function would be
200B +80M ≤ 1200

Solve with cramer's rule x+2y+3z=11, 2x+y+2z=10, 3x+2y+z=9
Answer:
x = 2 , y = 0 , z = 3
Step-by-step explanation:
Cramer's rule is a rule through which we can find the solution of linear equation.
we have the three linear equations as
x+2y+3z=11
2x+y+2z=10
3x+2y+z=9
AX=B
A: coefficient matrix
X= unknown vectors(x,y,z)
D = values of the linear equation (11 , 10 , 9)
now we find the determinant of the given linear equation
determinant of the matrix will be
A = [tex]\left[\begin{array}{ccc}1&2&3\\2&1&2\\3&2&1\end{array}\right][/tex] = 1(1-4) - 2(2-6) + 3(4 - 3)
= 1(-3) - 2(-4) + 3(1)
= -3+8+3 = 8
also D[tex]\neq 0[/tex]
so the determinant is Non zero we can apply Cramer's rule
we will be replacing the first column of the coefficient matrix A with the values of D
by replacing the first column we will get the value of the variable 'x'
Dx = [tex]\left[\begin{array}{ccc}11&2&3\\10&1&2\\9&2&1\end{array}\right][/tex] = 11(1-4) -2(10-18) + 3(20-9) = -33+16+33 = 16
x = [tex]\frac{Dx}{D}[/tex] = [tex]\frac{16}{8}[/tex] = 2
similarly
Dy = [tex]\left[\begin{array}{ccc}1&11&3\\2&10&2\\3&9&1\end{array}\right][/tex] = 1(10-18) -11(2-6) + 3(18 -30) = -8 +44 -36 = 0
y = [tex]\frac{Dy}{D}[/tex] = 0
Dz= [tex]\left[\begin{array}{ccc}1&2&11\\2&1&10\\3&2&9\end{array}\right][/tex] = 1(9 - 20) -2(18 - 30) + 11(4 -3) = -11 +24 +11 = 24
z = [tex]\frac{Dz}{D}[/tex] = [tex]\frac{24}{8} = 3[/tex]
so we have the solution as
x = 2 , y = 0 , z = 3
Therefore the solution for the given linear equations is (2,0,3).

4x ≥ 2
x ≥ [tex]\frac{1}{2}[/tex]
4x + 7 ≥ -9
4x ≥ -16
x ≥ -4

Answer:
y = -4/3x + 2Step-by-step explanation:
Use two points from the graph:
(0, 2) and (3, -2)Slope intercept formula:
y = mx + by-intercept is b = 2 as per the first point
Slope is found using slope formula:
m = (y2 - y1)/(x2 - x1)m = (-2 - 2)/(3 - 0) = -4/3So the equation is:

In her last basketball game, Carla scored 46 points. In the current game, she has scored 24 points so far. How many more two-points baskets must she make if she wants her total score in her current
game to be at least as great as her score in the last game?
Answer:
Carla needs to make at least 11 two-pointer shots in the surrent game
Step-by-step explanation:
The first thing we can do is to find the difference between the number of points that Carla scored in her first game and her second game.
This will be 46 - 24 = 22 points difference
Carla needs to make a certain number of two-pointers to get at least the same score she had in her previous game.
We can get this number of two-pointers that needed to be made by dividing the difference in scores by 2
i.e number of two-pointer shots = 22/2 =11 shots
Therefore, Carla needs to make at least 11 two-pointer shots to be able to get the same score in her current game.

The equation y = 40x shows the number
of words Diego types in x minutes. What is
the constant of proportionality?
Answer:
40
Step-by-step explanation:
i would say 40? because it will be a constant for how many times you do X. for example if it's Y = 40 (2) it would equal 80 because no matter what number you put in X 40 will have to be multiplied
Sushil was thinking of a number. Sushil subtracts 3.8 from the number and gets an answer of 53.6. Form an equation with
x
from the information.
Answer:
x = 3.8 + 53.6
Step-by-step explanation:
From the info that they gave you, you can tell that the original number is unknown, so that is x. Since Sushil is subracting 3.8, meaning, to get x, you're going to have to do the opposite which is........addition! So, to get x, you have to add 3.8, and 53.6. I hope I make sense!!
