Answer:2(xy-7)= -20
Step-by-step explanation:
Plug in -1 for x and 3 for 3, as the question says that x and y represent those values.
2(xy-7) = ?
2((-1)(3) - 7) = ?
2(-3-7)=?
2(-10)
-20
2(xy - 7) = -20
Answer:
k = -4 or 2
Step-by-step explanation:
For the lines to be parallel, the lines would need to be the same slope. This means to find the slope of each we would take the difference of the rise over the run.

and

To find K, set them equal.

Factor the quadratic and solve for K.

k+4=0 so k=-4
k-2=0 so k=2
Answer:
419 ft
Step-by-step explanation:
1063 ft is about 324002.4 mm
324002.4/477 to get the scale ratio. Which is 679.25:1
I am halfway through the problem and notice I should have converted mm to ft and not the other way around. It gives the same answer it just takes an extra step.
188*679.25=127699mm for one side.
Convert that back to ft and you get 418.959 which would just be 419 ft
<u>ANSWER</u>


<u>EXPLANATION</u>
To find the value of a function, f(x) at a given value x=a, we plug in x=a into f(x) to obtain f(a) in simplified form.
The first function is

To find f(7), we substitute x=7, into the function.

The second function is

To find f(4), we replace x with 4 to obtain,
