Assuming the x stands for multiplication... follow the ordering rules:

First let's take care of the exponents. 4²=16 and (-6)²=36. At the same time I will add some spacing between the terms:

3x16 - 36 + 4 - 6x4

Now do the multiplications:

48 - 36 + 4 - 24

The rest is just addition and subtraction

48 - 36 + 4 - 24 = -8

To describe a specific arith-
Bezzdna [24]

Answer:

f(x) = 7x + 30

Step-by-step explanation:

We need at least two points to write the equation of a straight line.

The recursive formula that Elijah wrote is:

f(0) = 30

f(n + 1) = f(n) + 7

When we substitute n=0, we get:

f(0 + 1) = f(0) + 7

f(1) = 30 + 7

f(1) = 37

The points (0,30) and (1,37) lies on this line.

The equation of this line is of the form:

f(x) = mx + b

where b =30 is the y-intercept and m=7 is the slope.

We plug in these values to get:

f(x) = 7x + 30

Note that the slope of the line is equal to the common difference of the Arithmetic Sequence.

You could also use the two points to find the slope:

m =  \frac{37 - 30}{1 - 0}  = 7

spayn [35]

Answer:

Their mass at the start was 400 kg.

Step-by-step explanation:

Given:

The tyres on a car during a grand prix race are reduced in mass by 3%. Their mass is 388 kg at the end of the race.

Now, to find the mass at the start.

<u>Let the mass at the start be x.</u>

According to question:

x - 3 \%ofx= 388

⇒x-\frac{3}{100}\times x = 388

⇒x-0.03x =388

⇒0.97x=388

<em>Dividing both sides by 0.97 we get:</em>

⇒x=400

Therefore, their mass at the start was 400 kg.
