Answer:
y = x² - 3x - 4
Step-by-step explanation:
Given that the x- intercepts are x = - 1 and x = 4, then the corresponding factors are
(x + 1) and (x - 4) and the quadratic is the product of the factors, that is
y = (x + 1)(x - 4) ← expand using FOIL
y = x² - 3x - 4

The number of people that can be safely carried in a lift depends on their mass. A lift will safely
carry 8 people with an average mass of 75 kg. How many people with an average mass of
100kg can safely travel in the lift?
Pls pls explain it with working (worry for exam) guys it’s maths not physics
Answer:
Step-by-step explanation:
If a lift will carry 8 people safely with an average mass of 75kg each we multiply to find the weight the lift can safely carry.
8 x 75kg = 600kg
If the average mass of the people is 100kg each, we divide to find the number of people it can carry. We know the lift can carry 600kg.
600kg/100kg = 6
So the lift can carry 6 people if their average mass is 100kg.
Please I need help and the calculation of which contract is better.
The monthly contract I am considering costs $30 per month with 75 minutes of free calls and 100 free text messages. Additional calls cost 10¢ per minute and additional text messages 10¢ each. An alternative is ‘Pay as you go’ which has no monthly charge but all calls cost 30¢ per minute and texts cost 10¢ each. I typically make 100 minutes of calls and 60 text messages each month. Which would be the better contract for me and by how much?
Answer:
You should go with the 1st, because it's cheaper.
Step-by-step explanation:
1st plan:
30$ which include 75 mins of free calls and 100 free text messages
25 more mins * 10¢ /min(0.1$/min) = 2.5$
You will pay 32.5$
2nd plan:
(calls)100*0.3$=30$
(text messages)100 * 0.1$=10$
30+10 = 40$

Answer:
m ≤ - 3
Step-by-step explanation:
Given
- 24 - 6m ≥ 4(m + 1) + 2 ← distribute parenthesis and simplify
- 24 - 6m ≥ 4m + 4 + 2
- 24 - 6m ≥ 4m + 6 ( subtract 4m from both sides )
- 24 - 10m ≥ 6 ( add 24 to both sides )
- 10m ≥ 30
Divide both sides by - 10, reversing the symbol as a result of dividing by a negative quantity.
m ≤ - 3
Answer:
uhhhhhh
m ≤ - 3

How can you determine whether the sum of several numbers, such as 13 + 45 + 24 +17, is odd or even without actually calculating the sum?
Answer:
Step-by-step explanation:
Hello,
odd + odd gives even
odd + even gives odd
so odd + odd + even + odd = even + even + odd = even + odd = odd
So the sum is a odd number
thanks
The sum of three odd numbers is odd and that added to an even number results in an odd number.
What are some other related concepts?An even number raised to the even or odd power is even and an odd number raised to the power of even or odd is always an odd number.
We know the sum of two even numbers is even, the sum of two odd numbers is also even and the sum of an odd and even number is odd and vice versa.
Given four numbers first two numbers are odd so their sum is even.
The next two numbers are even and odd so their sum is odd, Now the sum of even and odd is odd.

What is the smallest value of x that makes this inequality true?
2/3(4x-1)-6 is greater than or equal to, 7-(2x+9)
Answer:
it may be helpful for youAnswer:
x = 1 is trueStep-by-step explanation:
2/3(4x - 1) - 6 ≥ 7 - (2x + 9)
remove parenthesis:
2/3*4x - 2/3*1 - 6 ≥ 7 - 2x + 9
simplify:
8x/3 - 2/3 - 6 ≥ 2x - 2
combine similar terms:
8x/3 + 2x ≥ -2 + 2/3 + 6
simplify 14/3x ≥ 14/3

Answer:
m∠EBC = 62°
m∠EBA = 124°
m∠CBA = 62°
Step-by-step explanation:
It's given in the question that a line BC bisects angle EBA.
And m∠EBC = 62°
Since, BC is an angle bisector of ∠EBC,
Therefore, m∠EBC = m∠CBA = 62°
Since, m∠EBA = 2(m∠EBC)
Therefore, m∠EBA = 2 × 62° = 124°
