A student performed the following steps to find the solution to the equation
x2 - 2x - 8 = 0. Where did the student go wrong?
Step 1. Factor the polynomial into (x-4) and (x - 2)
Step 2. X-4 = 0 and x - 2 = 0
Step 3. x = 4 and x = 2
A. The student did not make any mistakes, the solution is correct
B. in Step 2
C. in Step 1
D. in Step 3
Answer:
step 1, c
Step-by-step explanation:
he was wrong in step 1.
when factoring out (x-4) and (x-2), you have to distribute x*x, x*-2, -4*x, and -4*-2
if you do it you get x^2 - 2x -4x + 8
the correct way to factor will be (x-4)(x+2)
when you factor out you will get the original equation you started with.

draw an ordered stem and leaf diagram to show infomation 245
Answer:
if asked to find stem leaf 245 scale key then 2 | 45 is what we could show to one side of the diagram.
We then use organise all numbers in numerical order lowest to highest in a horizontal list to copy.
Then draw a vertical line for your stem hopefully it is on lined paper.
single digits 1-9 go right side.
tenths get split keeping digits rights side
hundred units get split keeping tenth and single digits right side
and so forth so that nly the first number of larger numbers is on the left, just first digit. Being the first digit of numbers higher than 9.
Larger numbers that have 3 digits are more than double digits I've called 100th units
Numbers lower than 9 will be on rights side on the first line.
1-9 = 0 | 1 2 3 4 5 6 7 8 9
10-19 1 | 0 1 2 3 4 5 6 7 8 9
20-29 2| 0 1 2 3 4 5 6 7 8 9
100-110 = 1 | 00 01 02 03 etc.. becomes our first 100th line
We use thsi by counting how many numbers we have before drawing and by writing the scale key ie) 1|1 if 11 is shown etc. sometimes just called key.
Step-by-step explanation:
3x - 5y = 4
-2x + 6y = 18
Answer:
From 1st eqn .,
3x=4+5y
X=4+5y/3
From 2nd eqn ..,
-2x+6y=18
-2(4+5y/3)+6y=18
-8+10y/3 +6y=18
-8+10y+18y/3=18
-8+28y/3=18
-8+28y=54
28y=54+8
y=62/28
y=31/14
Therefore the value of y is 31/14
Again,
Putting the value of y in ..
X=4+5y/3
=(4+5*31/14)/3
=(211/14)/3
=211/42
Step-by-step explanation:
So the value of X and y is 31/14 &211/42 respectively.

The pyramid of Khafre measured 143.5 meters high. The pyramid of Menkaure measured 65.5 meters high. Write and solve an equation to find d, the difference in the heights of these two pyramid.
Answer:
See belowStep-by-step explanation:
The pyramid of Khafre measured 143.5 meters high.The pyramid of Menkaure measured 65.5 meters high.The difference in the heights of the two pyramids:
d = 143.5 m - 65.5 md = 78 mLets see
d is difference between the heights
143.565.5So
d=143.5-65.5d=78mA stack of 30 science flashcards includes a review card for each of the
following: 10 insects, 8 trees, 8 flowers, and 4 birds.
What is the probability of randomly selecting an insect?
The probability of randomly selecting an insect is 2/15.
What is probability?
It is a measure of happening or non happening of the outcomes of a random experiment.
Formula for probabilityP(E) = number of favorable outcomes/Total number of outcomes
Where, P(E) is the probability of any event.
Let E be an event of selecting an insect.
According to the given question
We have
Total number of insects = 10
Total number of trees = 8
Total number of flowers = 8
Total number of birds = 4
Now, the total number of outcomes = 10 + 8 + 8 + 4 = 30
Total number of favorable outcomes = 4
Therefore,
The probability of selecting an insect = [tex]\frac{4}{30} =\frac{2}{15}[/tex]

Which ordered pairs are solutions to the inequality 2x +y > -4? Select each correct answer. (0, 1) (-3,0) (4 – 12) (-1, -1) (5,- 12 )
Answer:
(5,-12)
(-3,0)
(-1,-1)
Step-by-step explanation:
For (4, −12): 2(4) - 12 = 8 - 12 = -4 [false]
For (−3, 0): 2(-3) = -6 < -4 [false]
For (5, −12): 2(5) - 12 = 10 - 12 = -2 > -4 [true]
For (0, 1): 2(0) + 1 = 1 > -4 [true]
For (−1, −1): 2(-1) - 1 = -2 - 1 = -3 > -4 [true]
Therefore, (5, -12), (0, 1) and (-1, -1) satisfies the inequality 2x + y > -4
For (7, 12): 12 - 2(7) = 12 - 14 = -2 > -3 [false]
For (0, −2): -2 - 2(0) = -2 > -3 [false]
For (5, −3): -3 - 2(5) = -3 - 10 = -13 < -3 [true]
For (−6, −3): -3 - 2(-6) = -3 + 12 = 9 > -3 [false]
For (1, −1): -1 - 2(1) = -1 - 2 = -3 [true]
Therefore, (5, -3) and (1, -1) satisfy the inequality y - 2x ≤ -3

what is [tex]−3.64⋅|5.3|−1.5^3[/tex]
Answer:
- 22.667
Step-by-step explanation:
1.5^3 = 1.5 x 1.5 x 1.5 = 3.375
- 3.64 ⋅ | 5.3 | - 1.5^3
= ( - 3.64 ⋅ | 5.3 | ) - 1.5^3
= ( - 3.64 ⋅ 5.3 ) - 1.5^3

Area = 15 × 5
Area = 75
perimeter = 15 + 6 + 15 + 6 = 42

Area = (10 × 15) ÷ 2 = 75
perimeter = 18 + 10 + 15 = 43

Area = (25 × 10) ÷ 2 = 125
perimeter = 31.6 + 25 + 11.2 = 67.8
