Answer:
3^2+2^2-5×2-6
9+4-10-6
-3
Step-by-step explanation:
-3 is the answer
Answer:
It could be solved by filling in "x" as 2.
Step-by-step explanation:
F(x) = 2^3 + x^2 - 5(2) - 6
f(x) = 8 + 4 -10 - 6
f(x) = 12 -16
= -4

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%

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.

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%.

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.

Find the area of the shape below.
16 cm
7 cm
7 cm
20 cm
Answer:
Area = 230 cm
Step-by-step explanation:
We can split this shape into different parts: a rectangle and a triangle (I attached an image below as a visual aid).
The area of a rectangle is given as:
[tex]Area = width * length[/tex]
and the area of a triangle is given as:
[tex]Area = \frac{1}{2} *base * height[/tex]
Let's first solve for the area of the rectangle. The width of the rectangle is 20cm, and the height of the rectangle is 7cm. So, the area is 7 × 20 = 140cm.
Now, let's solve for the area of the triangle. The base of the triangle is 20 cm, and the height of the rectangle is 16 - 7 = 9cm. So, the area is [tex]\frac{1}{2} * 20 * 9[/tex] = 90cm.
We add the two values together to get the combined area of the shape. 140 + 90 = 230 cm.

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]
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

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°
