Answer:
the answer is y^3+11y^2+22y-6
Answer:
y³ + 11y² + 22y - 6
Step-by-step explanation:
(y + 3)(y² + 8y - 2)
y(y² + 8y - 2)+ 3(y² + 8y - 2)
y³ + 8y² - 2y + 3y² + 24y - 6
y³ + 11y² + 22y - 6
Please answer these questions for me I wanna enjoy being outside today.
Answer:
1. y = 3x - 3
2. y = -2 1/2x + 10
10/-4 = -2 1/2 is the slope
3. undefined
4. y = x - 4
5. y = x - 5
6. 6x + 2y = 4 and -3y = 9x + 12
7. -3x + y = 7, y = 3x + 1, and y =3x
8. y = 2x + 5

The ages of the racers in a bicycle motocross race are 14, 22, 20, 25, 26, 17, 21, 30, 27, 25, 14, and 29. The 30-year-old drops out of the race and is replaced with a 15-year-old. How are the mean, median, and mode of the ages affected?
Answer:
The mean is decreased by 1.25.
The mode remains the same.
The median is decreased by 2 .
Step-by-step explanation:
Re arranging the data 14, 22, 20, 25, 26, 17, 21, 30, 27, 25, 14, and 29.
Gives
14, 14,17,20, 21, 22, 25,25, 26, 27, 29,30,
Now the mean = 14, +14,+17, +20, +21,+ 22, +25,+25,+ 26, + 27, +29,+30/12
Mean= 270/12=22.5
The Mode ( the repeated value) = 14,25
Median ( the average of middle value) = 22+25/2= 23.5
When 30 is replaced is by 15
Now the mean = 14, +14, +15,+17, +20, +21,+ 22, +25,+25,+ 26, + 27, +29/12
The Mean becomes = 255/12=21.25
The Mode ( the repeated value) = 14,25
Median ( the average of the middle value) = 21+22/2= 21.5
The difference between the 2 means is = 22.5- 21.25= 1.25
The mode remains the same.
The median is decreased by 2 .
The mean is decreased by 1.25 which is more than 50 % of the value obtained between the ratio of the omitted and added value (30/15=) i.e. 2
x increase by 10 is equal to 33
Answer:
x=23
Step-by-step explanation:
let's make this question into equation form
x increase by 10; or x+10
is equal to 33; or =33
so it would look like this; x+10=33
now we can solve it in reverse
33-10=23 so x is 23.
hope this helped, have a great day.

Answer would be (2x-3)
Henry and Gavin win some money and share it in the ratio 5:3. Henry gets £14 more than Gavin. How much did they get altogether?
Answer:
Total amount = £56
Step-by-step explanation:
Let Henry and Gavin be H & G respectively.
Let Henry's and Gavin's share be x.
Given the following data;
Ratio of H to G = 5:3
Henry = G + £14
Translating the word problem into an algebraic expression, we have;
5x = 3x + 14
5x - 3x = 14
2x = 14
x = 14/2
x = £7
Next, we determine the amount earned by Gavin;
Gavin = 3x
Gavin = 3*7
Gavin = £21
For Henry;
Henry = G + £14
Henry = £21 + £14
Henry = £35
Now, to find the total amount earned by Henry and Gavin.
Total amount = H + G
Total amount = 35 + 21
Total amount = £56

Solve the system of equations -3x+7y=-18 and 4x-4y=8 by combining the equations
Answer:
(-4, -3)
Step-by-step explanation:
Using elimination by addition and subtraction works best here.
Suppose we decide to eliminate x temporarily. To do this, we multipy the first row by 4, obtaining
-12x + 28y = -72
4x - 4y = 8
Next, multiply the second row by 3, obtaining the "equivalent system"
-12x + 28y = -72
12x - 12y = 24
Combining these equations, column by column, we get:
16y = -48. So y = -3.
Now let's find x. Substitute -3 for y in the second equation:
4x - 4(-3) = 8, or
4x + 12 = 8, or
4x = 8 - 12 = -4. This tells us that x = -4.
The solution is thus (-4, -3).

Answer:
The y intercept is added to the new parent function.
Step-by-step explanation:
The parent function changed because the y intercept (SLOPE) was added into the new parent function. In order to prove that the change took place with the y intercept being added to the function, you can use any value from 2 and up.
Completion of substitution for X:
Original parent function: Plug in 2 for x
(2)^3 = 8
Completion of substitution for X with NEW parent function: plug in 2 for x
(2)^3 + 2 = 10

Work out the area of the trapezium ABDE.
A
В.
7.5 cm
2.5 cm
С
5 cm
E
Answer:
Area = 50 cm²
Step-by-step explanation:
Area of a trapezium ABDE = ½(a + b)h
where,
a = BD = 2.5 cm
b = AE = 7.5 cm
h = DE = ?
We need to find DE ti be able to calculate the area.
DE = CE - CD
DE = CE - 5
Since ∆ACE is similar to ∆BCD, therefore:
AE/BD = CE/CD
Plug in the values
7.5/2.5 = CE/5
Cross multiply
CE*2.5 = 7.5*5
CE*2.5 = 37.5
Divide both side any 2.5
CE = 37.5/2.5
CE = 15
Thus, DE = CE - 5 = 15 - 5
DE = 10
✅Area of trapezium = ½(BD + AE)DE
= ½(2.5 + 7.5)*10
= ½(10)10
= 50 cm²
Chang knows one side of a triangle is 13 cm. Which set of two sides is possible for the lengths of the other two sides of this triangle?
Answer:
Choice D - 8cm and 9cm.
Explanation:
The other sides are not greater than 13.
A: 5 + 8 = 13
B: 6 + 7 = 13
C: 7 + 2 = 9
However, D is greater than 13 and is the correct answer.
D: 8 + 8 = 16.

1A) Quad ABCD is inscribed in the circle. Find x. *
1B) Using your answer from above, what is angle A? *
Step-by-step explanation:
2x + 9° + 3x + 1° =180° (opposite angles of a cyclic quadrilateral are supplementary)
5x + 10° = 180°
5x = 180° - 10°
5x = 170°
x = 34°
Now
Angle A
= 2 * 34° + 9°
= 77°
Hope it will help :)❤
Anyone good at geometry proofs? Help with math please. Thank you!
Answer and Step-by-step explanation:
1. Given
This part is given at the beginning of the problem.
2. Corresponding Angles Postulate
Because the lines are parallel, these two angles will be congruent by the corresponding angles postulate.
3. Same-Side Interior Angles Theorem
The same-side interior angles theorem has it so that the angles within parallel lines will add up to 180.
4. Substitution
We can use substitution here because we already determined that the measure of angle UTY is congruent to the measure of angle HGY.
I hope this helps!
#teamtrees #PAW (Plant And Water)
Answer:
Below.
Step-by-step explanation:
m <UTY + m <UTR = 180 degrees ( Angles on a straight line YR)
But m < UTR = m<RWX ( Corresponding angles in the parallel lines SU and VX)
So substituting for m< UTR in the first equation:
m <UTY + m<RWX = 180.
