Answer:

f= 11

Step-by-step explanation:

Plug in 7, for the variable t. It will equal 14 because 2 times 7 is 14. Subtract 3 from 14, and the answer is 11.

Here is the work shown.

f= 2t - 3, t= 7

f= 2(7) - 3

f= 14 - 3

f= 11

I hope this helps. :)

Answer:

f= 11

Explanation:

f= 2t-3 when t= 7 (just plug in 7 for the variable t!)

f= 2(7)-3

f= 14-3

f= 11

We know that in order to solve a math problem, we need an equation. Luckily there's an equation to find the slope and intercept of a (straight) line!

Because of the equation:

Y = mx + b

You can use it to find the Y intercept, and then therefore slope (or the other way around)!

First, look at the point where the line meets with the y axis.

It's not clear, but it's 7.

That's your 'Y intercept'. Easy!

Then, to find the slope. There are a couple of ways to find it, but I'll show you the one using the y = mx + b equation.

In the equation, 'b' represents the Y intercept. Since we already know our Y intercept on the graph is 7, we can plug that into the equation.

Y = mx + 7

What's m? M is the slope of the line. In order to find this, we need more numbers to work with. Numbers from the line's coordinate points.

Since coordinates in a graph have x and y, we can plug in any coordinate from the graph's line into our equation (y = mx +7).

I choose...this point (points at random coordinate on line).

(3, 10) aka (x, y)

It's on the line, right? So it will be a reliable x and y.

Put the numbers in...

10 = 3m + 7

This looks a bit easier, right? Now we solve for m (the slope)!

Combine like terms.

10 - 7 = 3m

Divide the 3.

3/3 = m

m = 1.

That's your slope!

So, taking the solution, we can determine that the slope of the line is 1, and the intercept of the line is 7.

Y = x + 7

Hope it helps! This is the most I can do for you :)

Explain work please
Softa [21]

Answer:

12 yards of silk

Step-by-step explanation:

okay so 1 yard = 36 inch so 2+3+6= 11 yards

now 1/2 of 36 is 18 inchs

6 inchs

and 1/3 of 36 is = 12

now add 12+18+6 = 36 = 1 extra yard so add that to 11 to get 12

Approximtely how many 27cubic volume cabinets will a container98,000cbic volume hold?
babymother [125]

Answer: 3630

Step-by-step explanation:

Given that:

Volume of container = 98,000 cubic volume

Volume of cabinet = 27 cubic volume

The number of cabinets which the container will. Hold equals:

Volume of container / volume of cabinet

= 98000 cubic volume / 27 cubic volume

= 3629.6296

The container will hold approximately 3630 27 cubic volume of cabinet.

madreJ [45]
7 1/2 = 15/2
Multiply 7 and 2, then add 1 = 15
Keep the denominator

3 2/3 = 11/3
Multiply 3 and 3, then add 2 = 11
Keep the denominator
