Given the expression m - 5w + 3m +4n + 2w, Jeriche rewrote it as 4m - 3w + 4n while John rewrote it as 8mn - 3w Who is operatorname correct? What did the other do wrong?
Answer:
eJeriche is correct, the answer is 4m - 3w + 4n, John didn't collect the like terms correctly
Step-by-step explanation:
Answer: 4m - 3w + 4n - this is the right decision.
Step-by-step explanation:
m - 5w + 3m + 4n + 2w = m + 3m - 5w + 2w + 4n = 4m - 3w + 4n
Jericho wrote correctly, and John - not.
John put together various variables n and m, which is not allowed.

Which equation goes with the circle?
Answer:
An equation of the circle with centre (-2,1) and radius 3 is [tex]\mathbf{(x+2)^2+(x-1)^2=9}[/tex]
Option D is correct.
Step-by-step explanation:
Looking at the figure we get centre of circle C (-2,1) and radius of circle r = 3
The equation of circle is of form: [tex](x-h)^2+(x-k)^2=r^2[/tex] where (h,k) is centre and r is radius.
We have centre C (-2,1) so, we have h = -2 and k = 1
We have radius = 3 so, r = 3
Putting values in the equation and finding the required equation:
[tex](x-h)^2+(x-k)^2=r^2\\(x-(-2))^2+(x-1)^2=(3)^2\\(x+2)^2+(x-1)^2=9[/tex]
So, an equation of the circle with centre (-2,1) and radius 3 is [tex]\mathbf{(x+2)^2+(x-1)^2=9}[/tex]
Option D is correct.

Kylie buys cranberries and raspberries in the ratio of 8:9 to prepare mock tails. If she buys 64 ounces of cranberries what is the total weight of berries purchased
Answer: 136 ounces
Step-by-step explanation:
Given: The ratio of cranberries and raspberries is 8:9 .
Let quantity of cranberries= 8x , quantity of raspberries = 9x
If quantity of cranberries = 64 ounces
[tex]\Rightarrow\ 8x=64\\\\\Rightarrow\ x=\dfrac{64}{8}\\\\\Rightarrow\ x=8[/tex]
Quantity of raspberries = 9(8) = 72 ounces
Total quantity = 64 ounces + 72 ounces = 136 ounces
Hence, the total weight of berries purchased= 136 ounces

Solution,
Given,
f(x) = -4x + 7
g(x) = [tex]x^{3}[/tex]
Now,
fog(x) = f{g(x)} = f([tex]x^{3}[/tex]) = -4[tex]x^{3}[/tex]+7

X = ?
Answer:
x=6.5
Step-by-step explanation:
Don't worry I just know
Answer:
X = 13/2
Step-by-step explanation:
7(x-2)=3(x+4)
Distribute
7x - 14 = 3x + 12
-3x from both sides
4x -14 = 12
Add 14
4x = 26
Dive by 4
X = 13/2

The students in a class made graphs to keep track of the number of pages they read in their books.
Which graph shows a proportional relationship?
A.
B.
C.
D.
Step-by-step explanation:
A proportional relationship graph would show that the points can be arranged in a line that passes through the origin.
All of the points in Graphs B, C and D cannot be connected in 1 straight line, hence they are not proportional relationships.
Only Graph A shows a proportional relationship.

Which of the following is a solution to the system of two equations y = 3x – 7 and 4x – 5y = -20?
Answer:
x = 5, and y = 8
Step-by-step explanation:
You can solve this system by solving either of the equations for either x or y, and substituting that into the other.
Since the first equation is already defined for y, let's substitute that into the second equation:
4x - 5y = -20
4x - 5(3x - 7) = -20
4x - 15x + 35 = -20
4x - 15x = -20 - 35
-11x = -55
x = 5
We can then plug that into either of the original equations to find y:
y = 3x - 7
y = 3 * 5 - 7
y = 15 - 7
y = 8
We can also verify our answer by plugging one of the values into either of the original equations and seeing what we get:
4x - 5y = -20
4x - 5 * 8 = -20
4x - 40 = -20
4x = 20
x = 5
So we know the answer is correct. x is equal to five, and y is equal to eight.
