Answer:

d > - 7

Step-by-step explanation:

Here, d represents the number of dollars in John's bank account at the end of the month.

As per statement,

In John's account,

The balance must be more than -7 dollars,

That is, Number of dollars at the end of each month > - 7 ( '>' is used for more than )

⇒ d > - 7

Which is the required inequality.

D > -7. Notice that it is > and not >=, because it is more than. Curious it says -7 dollars, and not a positive value

Which is a possible number of distinct real roots for a cubic function? Select all that apply.
Neko [114]

Answer:

3

Step-by-step explanation:

3 is a possible number of distinct real roots for a cubic function.

The maximum possible number of distinct roots are equal to the degree of any polynomial function.

Hence quadratic function has 2 roots

Cubic has 3

Linear has 1

Triangle ABC has vertices A(0,6) B(4,6) C(1,3). Sketch a graph of ABC and use it to find the orthocenter of ABC. Then list the s
Allisa [31]

For line B to AC:  y - 6 = (1/3)(x - 4);  y - 6 = (x/3) - (4/3); 3y - 18 = x - 4, so 3y - x = 14

For line A to BC:  y - 6 = (-1)(x - 0);  y - 6 = -x, so y + x = 6

Since these lines intersect at one point (the orthocenter), we can use simultaneous equations to solve for x and/or y:

(3y - x = 14) + (y + x = 6) =>  4y = 20, y = +5;  Substitute this into y + x = 6:  5 + x = 6, x = +1

<span>So the orthocenter is at coordinates (1,5), and the slopes of all three orthocenter lines are above.</span>

4. Represent the ordered pairs in the mapping diagram as a set of ordered pairs and as a table.
Firlakuza [10]

Answer/Step-by-step explanation:

✔️As a set of order pairs, the mapping can be represented as (x, y), where x = input and y = output.

Thus:

{(1, 6), (2, 6), (3, 6), (4, 8)}

✔️As a table we have input as x, and y as output, such as:

x | y

1 | 6

2 | 6

3 | 6

4 | 8

Please answer this!! (In your own words.) The best answer gets brainliest!<br><br> Find the area:
Wittaler [7]

Answer:

<em>97.5 sq. ft.</em>

Step-by-step explanation:

Im presuming the question asks to find area of the shaded region.

First of all, the total figure is a rectangle. We can write an expression(in words) for the shaded area.

<em>Shaded Area = Area of Rectangle - Area of Small Triangle(White) - Area of Large Triangle(White)</em>

Now, we find respective areas.

Area of rectangle:

length * width = (5+10) * (12) = 15 * 12 = 180

Area of Small Triangle (white):

A = (1/2) * base * height = (1/2) * 5 * (12-3) = (1/2) * 5 * 9 = 22.5

Area of Large Triangle (white):

A = (1/2) * base * height = (1/2) * 10 * (12) = 60

Now, we find area of shaded region:

<em>Shaded Area = Area of Rectangle - Area of Small Triangle(White) - Area of Large Triangle(White)</em>

<em>Shaded Area = 180 - 22.5 - 60 = 97.5 sq. ft.</em>
