Step-by-step explanation:

what did it mean to have an x-(axis-)intercept ?

just imagine the function curve gets closer and closer to the x-axis, and then finally intersects it.

that means there is a point on this function that is also on the x-axis.

what are the coordinates of points on the x-axis ?

well, sure, for x any value from -infinity to +infinity is possible.

but what about y ? what values can y have for points on the x-axis ? greater than 0 ? lower than 0 ?

no, if y would have any value different than 0, this point would not be ON the x-axis.

so, we know, the interception point must have y = 0.

and that is what we use in our function equation :

0 = 3 - 5x

5x = 3

x = 3/5

so, at x=3/5 there is the x-interception with the point coordinates (3/5, 0).

Need help with 2,3,4

Harman [31]

Answers:

In these exercices are ilustrated the representations of the fractions

2) Firstly, we have 3 equal segments, each one representing $\frac{1}{4}$ , hence:

$\frac{3}{4}$ is 3 copies of $\frac{1}{4}$

Let's prove it, taking into account we are adding fractions with the same denominator:

$\frac{1}{4}+\frac{1}{4}+\frac{1}{4}=\frac{3}{4}$

There are 4 equal parts that make a whole

Four copies of $\frac{1}{4}$ make $\frac{4}{4}$ or 1 whole

$\frac{1}{4}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4}=\frac{4}{4}=1$

3) Here we have a line divided into four segments, each one of $\frac{1}{5}$ . Hence:

This is $\frac{4}{5}$ of a line. $\frac{4}{5}$ is 4 lengths of $\frac{1}{5}$

$\frac{1}{5}+\frac{1}{5}+\frac{1}{5}+\frac{1}{5}=\frac{4}{5}$

If we draw one more $\frac{1}{5}$ we will have $\frac{5}{5}$ or 1 whole.

Then:

5 lengths of $\frac{1}{5}$ make $\frac{5}{5}$ or 1 whole.

4) In this part the answer is in the attached image. If we have two equal segments, each one of $\frac{1}{3}$ we will have as a result $\frac{2}{3}$ .

If we add another $\frac{1}{3}$ segment, we will have three segments of $\frac{1}{3}$ , having as a result $\frac{3}{3}=1$

Least to greatest;]

alexandr1967 [171]

Answer:

Least to greatest is: 0.0625, 6.75% and $\frac{7}{10}$ .

Step-by-step explanation:

Given:

The three quantities to compare are:

6.75%, 0.0625, and $\frac{7}{10}$

Let us convert each into percentage.

6.75% is already in percentage.

We multiply a number by 100 to convert it to percentage form.

So, $0.0625\times 100=6.25\%$

$\frac{7}{10}\times 100=\frac{700}{10}=70\%$

Now, on comparing all the three percentage, we conclude that,

70% is the greatest and 6.25% is the least.

So, order from least to greatest is:

$6.25\%$

What are the explicit equation and domain for an arithmetic sequence with a first term of 5 and a second term of 3?

meriva

Any arithmetic sequence can be expressed as:

a(n)=a+d(n-1), a=initial term, d=common difference, n=term number

In this case a=5, and d=-2 so

a(n)=5-2(n-1) which can be simplified...

a(n)=5-2n+2

a(n)=7-2n

The domain is restricted to integers from 1 to +oo.
