Answer:

Sample Answer: When a linear function is expressed in different forms, its slope and y-intercept remain the same. The slope from the equation is -1, and the y-intercept from the equation is 3. The slope from the table is -1, and the y-intercept from the table is −3. These are not the same functions.

Answer:

The slope formula is y2 - y1/x2 - x1.

Step-by-step explanation:

First plug in x = 1, x = 2, and x = 3 in to the equation y = 4x to find the first 3 points(Like the first three are shown for the table.) which are (1, 4), (2, 8), and (3, 12).

The slope of the table would be 9 - 3/3 - 1, after subtracting you get 6/2. You would then divide 6 by 2, which gives you 3. 3 is the slope of the table.

The slope of the equation goes through the same process. 12 - 4/3 - 1, after subtracting it's 8/2, and after dividing you get 4. The slope of the equation is 4.

This means the equation has the greater slope.

Leona [35]

Answer: Discounted function will be

$C(x)=6750+150t$

Step-by-step explanation:

Since we have given that

Initial cost of solar energy = $9000

Average annual cost of heating a home with solar energy = $200

Rate of discount he received on the total cost = 25%

Let the number of year will be t

According to question, we need to write a discounted cost as a function of number of years.

So, our function becomes,

$C(x)=\frac{100-25}{100}(9000+200t)\\\\C(x)=\frac{75}{100}(9000+200t)\\\\C(x)=0.75(9000+200t)\\\\C(x)=9000\times 0.75+200\times 0.75t\\\\C(x)=6750+150t$

Hence, discounted function will be

$C(x)=6750+150t$

Jacob is dividing 6 aquariums into of an aquarium sections for his different animals. How many 's are there in Jacob's 6 aquariu

anastassius [24]

Answer:

Jacob is dividing 6 aquariums into 1/8 of an aquarium sections for his different animals. How many 1/8's are there in Jacobs aquariums?

To get the number of 1/8 in Jacobs aquariums,we simply divide 6 by 1/8

6 ÷ 1/8

But whenever you are dividing by a fraction, you can simply change the division to multiplication in order to make your work easier, all you need to do to change the division to multiplication is to simply turn the number over, that is; the denominator becomes the numerator and the numerator becomes the denominator,

In this case 8 becomes the numerator and 1 becomes the denominator

Hence;

6 × 8 /1 = 6 × 8 = 48

Therefore, the number of 1/8's in Jacobs aquariums are 48

Hope this helps, have a great day/night, and stay safe!
