PLEASE HELP MEEEEE THIS IS SO HARDDD
Answer:
B and $684
Step-by-step explanation:
B, because wednesday is three days after sunday so 4 times 3 because she walks 4 more laps each day until saturday. Add the 24 laps she already walks 4(3)=12+24=36
By saturday she would've walked 48 laps, so 48 times 3 for the 3 dollars each lap. 48(3)=144 now u have to find the other days so the equation you would use is 3(24 + 4x), x for the day until saturday. 3(24+4(1))=3(28)=84,just do that for each day and then add all them together because the question asked by the end of the week, saturday, how much money so yea. 84+96+108+120+132+144=684
(honestly u could just keep adding 12 to the previous number as that's what it's increasing by.) haha rlly hope I'm not wrong on the second one. Have a nice day!

c. X+ 7x2 - 6x + 3
d. 3x - 7x2 + 8x - 3
Answer:
B.2[tex]x^3[/tex] - 7[tex]x^2[/tex] + 8x -3
Step-by-step explanation:
To multiply a binomial (2 terms) by a trinomial (3 terms):
Multiply the first term of the binomial by the each term of the trinomial.
Multiply the second term of the binomial by each term of the trinomial.
Combine the expressions and simplify.
(2x-3)*([tex]x^2[/tex]-2x+1)
(2x * [tex]x^2[/tex]) + (2x * -2x) + (2x * 1)
(2[tex]x^3[/tex]) + (-4[tex]x^2[/tex]) + (2x)
(2x-3) * ([tex]x^2[/tex]-2x+1)
(-3 * [tex]x^2[/tex]) + (-3 * -2x) + (-3 * 1)
(-3[tex]x^2[/tex]) + (6x) + (-3)
[2[tex]x^3[/tex] + -4[tex]x^2[/tex] + 2x] + [-3[tex]x^2[/tex] + 6x + -3]

There were 26 students in the class 2 of them later moved to another
school. The teacher wants to place students at an equal number at each of 4
tables. How many students did the teacher place at each table?
Answer:
6 at each table
Step-by-step explanation:
26 - 2 is 24 and 6 times 4 is 24
Answer:
6 students
Step-by-step explanation:
There's a total of 26 so take the 2 students out so now you will have 24. Just do 24 divided by 4 and you will get 6.
Find the equation of the quadratic function with vertex (-2,18) passing through (-5,0)?
Answer:
[tex]y-18=-2(x+2)^2[/tex]
Step-by-step explanation:
Equation of the Quadratic Function
The vertex form of the quadratic function has the following equation:
[tex]y-k=a(x-h)^2[/tex]
Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.
It's been given the vertex of the parabola as (-2,18):
[tex]y-18=a(x+2)^2[/tex]
Now substitute the point (-5,0) and find the value of a:
[tex]0-18=a(-5+2)^2[/tex]
Operating:
[tex]-18=a(-3)^2[/tex]
[tex]-18=9a[/tex]
Solving for a:
[tex]a = -18 / 9[/tex]
a = -2
Thus, the equation of the quadratic function is:
[tex]\mathbf{y-18=-2(x+2)^2}[/tex]
What is the solution for x in the equation?
9x - 20 - 4x = 40?
X=1/4
X=4
X=12
X=1/12
Answer:
x = 12
Step-by-step explanation:
9x - 20 - 4x = 40
Combine like terms
5x -20 = 40
Add 20 to each side
5x -20+20 = 40+20
5x = 60
Divide by 5
5x/5 = 60/5
x = 12
9x - 20 - 4x = 40
By transposition method, we get
9x - 4x = 40 + 20
By simplifying the like terms, we get
5x = 60
or, x = 60/5 = 12
The value of x is 12.

8. Ten friends go out for dinner. The total cost of the meals is $141. Some
friends have three-course meals and the rest have two-course meals. Each
of the three-course meals costs $15 and each of the two-course meals
costs $12. The number of people who have three-course meals is x, so the
number of people who have two-course meals is 10 - x. How many three
course meals are possible?
2 three-course meals
20 three-course meals
e
7 three-course meals
5 three-course meals
Answer:
7 three-course meals
Step-by-step explanation:
7 x 15= 105
141-105= 36
36/12= 3
7+3= 10
So total, there are 10 meals; 7 three-course and 3 two-course

Solve the system of equations.
\begin{aligned} &-6y+11x = -36 \\\\ &-4y+7x=-24 \end{aligned}
−6y+11x=−36
−4y+7x=−24
Answer:
The solutions to the system of equations will be:
[tex]y=6,\:x=0[/tex]
Step-by-step explanation:
Given the equation
[tex]-6y+11x=-36[/tex]
[tex]-4y+7x=-24[/tex]
solving the system of equations
[tex]\begin{bmatrix}-6y+11x=-36\\ -4y+7x=-24\end{bmatrix}[/tex]
[tex]\mathrm{Multiply\:}-6y+11x=-36\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:-12y+22x=-72[/tex]
[tex]\mathrm{Multiply\:}-4y+7x=-24\mathrm{\:by\:}3\:\mathrm{:}\:\quad \:-12y+21x=-72[/tex]
[tex]\begin{bmatrix}-12y+22x=-72\\ -12y+21x=-72\end{bmatrix}[/tex]
[tex]-12y+21x=-72[/tex]
[tex]-[/tex]
[tex]\underline{-12y+22x=-72}[/tex]
[tex]-x=0[/tex]
[tex]\begin{bmatrix}-12y+22x=-72\\ -x=0\end{bmatrix}[/tex]
solving for x
[tex]-x=0[/tex]
[tex]\mathrm{Divide\:both\:sides\:by\:}-1[/tex]
[tex]\frac{-x}{-1}=\frac{0}{-1}[/tex]
[tex]x=0[/tex]
[tex]\mathrm{For\:}-12y+22x=-72\mathrm{\:plug\:in\:}x=0[/tex]
[tex]-12y+22\cdot \:0=-72[/tex]
[tex]-12y+0=-72[/tex]
[tex]-12y=-72[/tex]
[tex]\mathrm{Divide\:both\:sides\:by\:}-12[/tex]
[tex]\frac{-12y}{-12}=\frac{-72}{-12}[/tex]
[tex]y=6[/tex]
Therefore, the solutions to the system of equations will be:
[tex]y=6,\:x=0[/tex]
