Step-by-step explanation:
Maricella solves for x in the equation 4 x minus 2 (3 x minus 4) + 4 = negative x + 3 (x + 1) + 1. She begins by adding –4 + 4 on the left side of the equation and 1 + 1 on the right side of the equation. Which best explains why Maricella’s strategy is incorrect?
Answer:
It is wrong because she should simplify both sides of the equation,distribute, combine like terms,subtract and divide to get the final answer.
4x−2(3x−4)+4=−x+3(x+1)+1
Step 1: Simplify both sides of the equation.
4x−2(3x−4)+4=−x+3(x+1)+1
4x+(−2)(3x)+(−2)(−4)+4=−x+(3)(x)+(3)(1)+1(Distribute)
4x+−6x+8+4=−x+3x+3+1
(4x+−6x)+(8+4)=(−x+3x)+(3+1)(Combine Like Terms)
−2x+12=2x+4
−2x+12=2x+4
Step 2: Subtract 2x from both sides.
−2x+12−2x=2x+4−2x
−4x+12=4
Step 3: Subtract 12 from both sides.
−4x+12−12=4−12
−4x=−8
Step 4: Divide both sides by -4.
−4x−4=−8−4

Last year, the hiking club had 25 members. This year, there’s 37. What is the percent increase?
Answer:
The hiking club's member count increased by 48%.
Step-by-step explanation:
We are given two data values: 25 members and 37 members. We need to determine how many members the club gained first. We can set up an equation where we solve for an unknown, or x, in this case.
[tex]25 + x = 37\\\\x = 12[/tex]
The club increased by 12 members, so now we can divide this value by the initial amount of members and multiply the decimal we receive by 100 to express it in percentage form.
[tex]\frac{12}{25} =0.48\\\\0.48 \times 100 = 48\%[/tex]
Therefore, the club's member count increased by 48%.
Answer:
25+12=37
There would be 48%.

Point M is the midpoint of A and B
What are the coordinates of point B?
Answer:
(6, 7) is where B is.
Step-by-step explanation:
If you go down 1/2 and right 5, you get to M. If you go another 1/2 down and right 5, you will get to B.
This is because M is the midpoint, or center point, of line AB. That means there is equal distance going from A to M and equal distance going from B to M.

f(x) = x2+ x–1 and g(x) = x+ 3, what is f o g(x)
Answer:
Step-by-step explanation:
[tex]f(x) = x^2 + x - 1\\g(x) = x +3\\\\\\(f\:o\:g)(x) = f(g(x))[/tex]
we input the function g(x) into every x in f(x)
[tex]f(g(x)) = (x+3)^2 + (x + 3) - 1\\f(g(x)) = x^2 + 6x + 9 + x + 3 - 1\\f(g(x)) = x^2 + 7x + 11[/tex]

On the Cartesian plane, the midpoint between two points $A(a,b)$ and $B(c,d)$ is $M(m,n)$. If $A$ is moved vertically upwards 8 units and horizontally to the right 2 units, and $B$ is moved vertically downwards 2 units and horizontally to the left 10 units, then the new midpoint between $A$ and $B$ is $M'$. What is the distance between $M$ and $M'$?
Answer:
5
Step-by-step explanation:
The distance between M and M' is 5 units in the cartesian plane.
What is Distance?The length along a line or line segment between two points on the line or line segment.
The midpoint M of A(a,b) and B(c,d) is given by:
M(a+c/2, b+d/2)
After the two points are moved, the new coordinates are A'(a+2,b+8) and B'(c-10,d-2).
The new midpoint M' of A'(a+2,b+8) and B'(c-10,d-2) is given by:
M'(a+2+c-10/2 , b+8+d-2/2)
M'(a+c-8/2 , b+d+6/2)
To find the distance between M and M', we can use the distance formula:
d(M,M')=√((a+c)/2 - (a+c-8)/2)²+((b+d)/2-(b+d+6)/2)²
=√4²+(-3)²
=√16+9
=5 units
Hence, the distance between M and M' is 5 units.

A meteorologist predicted 28 mm of rain on Friday. The actual amount of rain measures 35 mm. What's the percent error in the meteorologist's prediction? Help plz
Given:
Predicted value of rain = 28 mm
Actual amount of rain = 35 mm
To find:
The percent error.
Solution:
We know that,
[tex]\text{Percent error}=\dfrac{\text{Predicted value - Actual value}}{\text{Actual value}}\times 100[/tex]
On substituting the values, we get
[tex]\text{Percent error}=\dfrac{28-35}{35}\times 100[/tex]
[tex]\text{Percent error}=\dfrac{-7}{35}\times 100[/tex]
[tex]\text{Percent error}=\dfrac{-1}{5}\times 100[/tex]
[tex]\text{Percent error}=-20\%[/tex]
Therefore, the percent error is -20%.

As soon as a new car is purchased and driven away from the dealership, it begins to lose its value, or depreciate. Alonso bought a 1994 Plymouth Neon for $9559. One year later, the value of the car was $8500. What was the percent of decrease of the value of the car?
P.S. This is a percent increase/decrrease
from: 9559
to: 8500
%/100 = differences of to and from/ from ( before the number )
( no negative difference, bigger number subtract smaller number)
Answer:
11%
Step-by-step explanation:
$9559-$8500=1059
1059/9559= .110786
.110786 x 100= 11.0786%
11.0786%= 11%

Answer:
8. 95°
9. 85°
10. 49°
11. 53°
Step-by-step explanation:
8) m + 28° + 57° = 180°
m = 180°–28°–57°
m = 95°
9) m∆4 + m∆5 = 180°
95° + m∆5=180°
m∆5 = 180°–95°
m∆5 = 85°
10) 180°–36°–95°=49°
11) 180°–42°–85°=53°
