Answer:
x=-24
Step-by-step explanation:
Remember that to find the zeroes of a quadratic expression of the form

we could either factor it or use the quadratic formula. When

, like in our case, is often way easier and faster factor the expression than using the quadratic formula. The only thing we need to do to factor the expression is find tow number whose product is 48 and its sum is 14; those numbers are 6 and 8.

and

. Now we can factor our quadratic like follows:

Since we are trying to find the zeroes of the function, we are going to set each one of our factored binomial equal to zero and solve for x:


and


We can conclude that the zeroes of the function

are

and

.
Answer:
The number associated with point M is 5.64
Step-by-step explanation:
notice that there are 10 divisions marked with ticks in between 5.6 and 5.7. So that means that the difference between these two numbers : 5.7 - 5.6 = 0.1
has been subdivided into 10: 0.1/10 = 0.01
Therefore we can assign a real number to each of the ticks by adding successively increments 0.01 (starting from the left "5.6"), and learn which number corresponds to the point M.
Please see the attached image that illustrates this, and shows in red the number assigned to the tick where point M is located: 5.64
Answer:
Answer is in the link
Step-by-step explanation:
There is no link UWU
It is instructed to subtract (2a−3b+4c) from the sum of (a+3b−4c),(4a−b+9c) and (−2b+3c−a).
So, First we will do the sum of the three given polynomials,
Sum =(a+3b−4c)+(4a−b+9c)+(−2b+3c−a)
=(a+4a−a)+(3b−b−2b)+(−4c+9c+3c)
=4a+8c
Now, we can perform the subtraction,
∴ Required difference
=(4a+8c)−(2a−3b+4c)
=4a+8c−2a+3b−4c
=2a+3b+4c
