Answer: OPTION D .

Step-by-step explanation:

1. By definition the function cut or intersects the y-axis when the value of x is equal 0 (x=0).

2. Therefore, you can observe the table given in the problem and see the value of y when x is equal to zero.

3. Keeping this on mind you can see that when x=0, y=8.

Therefore, you can conclude that the y-intercept in the table is 8.

4. As you can see in the graph, the y-intercept is at 5.

5. Then, since 5<8, the answer is the option D

Answer:

Option D is correct

Step-by-step explanation:

The y-intercept is the point where the graph of a function crosses the y-axis. At this point, the x-coordinate is usually zero. Thus, the y-intercept of the function on the table is 8 while on the graph this value is 5.

Nathan opens a new savings account and makes an initial deposit of $400.

AfilCa [17]

Answer:

The answer to the first one is 6

Step-by-step explanation:

If the time frame given is 9 months, then we can find that 9 months is 3/4 of a year. 3/4 x 2% = 0.015. 0.015 x 400 = 6. He would have made 6 dollars in 9 months.

Answer the the second one:

4.5% x 5 (years) = 0.225. 0.225 x 10,000 = 2,250. Since this is a car loan and not a bank interest for example, we add it to the total cost. I'm pretty sure its the third one.

How many positive four-digit integers are multiples of 5 and less than 4,000

Volgvan

Answer:

Number of positive four-digit integers which are multiples of 5 and less than 4,000 = 600

Explanation:

Lowest four digit positive integer = 1000

Highest four digit positive integer less than 4000 = 3999

We know that multiples of 5 end with 0 or 5 in their last digit.

So, lowest four digit positive integer which is a multiple of 5 = 1000

Highest four digit positive integer less than 4000 which is a multiple of 5 = 3995.

So, the numbers goes like,

1000, 1005, 1010 .....................................................3990, 3995

These numbers are in arithmetic progression, so we have first term = 1000 and common difference = 5 and nth term(An) = 3995, we need to find n.

An = a + (n-1)d

3995 = 1000 + (n-1)x 5

(n-1) x 5 = 2995

(n-1) = 599

n = 600

So, number of positive four-digit integers which are multiples of 5 and less than 4,000 = 600

The slope-intercept form of a linear equation is y=mx + b, where x and y are

HACTEHA [7]

Answer:

m = $\frac{y-b}{x}$

Step-by-step explanation:

Given

y = mx + b ( isolate the term in m by subtracting b from both sides )

y - b = mx ( divide both sides by x )

$\frac{y-b}{x}$ = m

Find the domain and range of the exponential function h(x) = –343x.

Amanda [17]

The function is supposed to be;

h(x) = -343^(x)

Answer:

The domain will be a set of real numbers while the range will be y ≤ 0 and on the interval (-∞, 1)

As x is increasing, h is decreasing and as x is decreasing, h is increasing

Step-by-step explanation:

We are given the function as;

h(x) = -343^(x)

The formula is;

y = a^(x) since it's symmetrical to the x-axis

However in this case;

y = -a^(x)

Now, the domain is y and the range is a set of values of x.

I've attached a graph of this function drawn on desmos.

From the graph we can see that The domain will be a set of real numbers while the range will be on the interval (-∞, 1)

For a value of x = 0,we have;

h(0) = -343^(0)

h(0) = -343

When we increase the value of x to 3,we have;

h(3) = -343^(3)

h(3) = -40353607

When we decrease the value of x to -3, we have;

h(-3) = -343^(-3)

h(-3) = 0.00000002478

Thus, we can conclude that;

As x is increasing, h is decreasing and as x is decreasing, h is increasing
