Find the equation of the linear function represented by the table below in slope-intercept form.

Mathematics

tatuchka [14]3 years ago

Answer:

y=x-4

Step-by-step explanation:

the values we have are:

x       y

-3     -7

2      -2

7       3

12     8

This means that the y value when x = -3 is y = -7, and the y value when x = 2 is y = -2, and so on with the rest of the table.

We can see that the y value is always 4 less than the x value:

-7 is 4 less than -3

-2 is 4 less than 2

3 is 4 less than 7

8 is 4 less than 12.

Thus, the equation of this linear function in the slope-intercept form  ( y=mx+b ) is:

y=x-4

How am I supposed to find ‘t’ here?
Softa [21]

You can solve for (T)

y =  - 16t {}^{2} + 400 \\ add \: both \: side \: by \:  - 16t {}^{2}   \\  - 16t {}^{2}  =  - 400  \\ divide \: both \: side \: by16 \\ t {}^{2} =  - 25 \\ t =  \sqrt{25}   \\ t = 5 \\ \: also \: it \: can \: be \:  - 5 \\  +  - 5 \\  \\

Hope this help :)

The 6% state income tax on a 42'000 salery​
Romashka [77]

Answer:

well, simply, it would be $2520.

in reality, an income tax does not work that simply. income taxes are figured using brackets, where (just making up numbers) the first $15000 might be taxed at 2%, earnings between $15,001 to $30,000 are taxed at 4%, and so on.

Thus, without knowing the tax tables to know the different rates and brackets, it's impossible to give an answer.

But in straight math terms, 6% of $42,000 is $2520

42000×.06= 2520

Martin combined different amounts of orange juice, pineapple juice, and strawberry juice to make 1850 milliliters (ml) of fruit
stealth61 [152]
The answer is 450 ml.

First, we need to solve x (the amount of orange juice):
<span>x + (x + 100) + one half x = 1850
</span>x + x + 100 + 1/2 x = 1850

We can represent 1/2 as 0.5:

2x + 100 + 0.5x = 1850
2.5x = 1850 - 100
2.5x = 1750
x = 1750 ÷ 2.5
x = 700.

Thus, in the fruit punch, there is 700 ml of orange juice.

<span>The amount of pineapple juice combined was 100 ml more than the amount of orange juice. Therefore, there is 800 ml of pineapple juice (700 ml of orange juice + 100 ml more).
</span>
The amount of strawberry juice was half the amount of orange juice. Therefore, there is 350 ml of strawberry juice (700 ml of orange juice ÷ 2).

<span>The difference in the amounts of pineapple juice and strawberry juice Martin combined is 450 ml:
</span>the amounts of pineapple juice - the amounts of strawberry juice =
800 ml of pineapple juice - <span>350 ml of strawberry juice = 450 ml.

</span>
