Answer:

Answer: y - 8 = x - 7

Step-by-step explanation:

SOLUTION:

General equation : (y2 - y1)/(x2 - x1) = slope

.

Substitute slope = 1 into the equation:

(y2 - y1)/(x2 - x1) = 1

.

Substitute (7, 8) into the equation:

(y - 8)/(x - 7) = 1

.

Cross multiply:

y - 8 = x - 7

.

Answer: y - 8 = x - 7

I really hope dis Helps :D

Answer:

1x - y + 1 = 0

Step-by-step explanation:

The equation for the point-slope equation is y - y1 = m(x - x1). Substitute y1 for 8, m for 1, and x1 for 7. Keep y & x as they are.

y - 8 = 1(x - 7)

<em>Use the distributive property to multiply 1 by x - 7.</em>

y - 8 = 1x - 7

<em>Now, add 8 to both sides.</em>

y = 1x - 7 + 8

<em>Add 8 to -7 to get 1.</em>

y = 1x + 1

<em>Now convert that into point slope form by doing the following: Split "1x + 1" by putting -y (opposite of y) in the middle of the left side, and then putting 0 on the right.</em>

1x - y + 1 = 0

The point slope equation of the shown question is 1x - y + 1 = 0.

HELP! ASAP!
Novosadov [1.4K]

Step-by-step explanation:

Part A:

So the height is going to be x when you fold the sides up. So that's one part of the volume but for the width it was going to be 4 but since two corners were cut out with the length x the new width is going to be (4-2x). The same thing applies for the length which should be 8 inches but since two corners were removed with the length x it's now (8-2x)

v = x(4-2x)(8-2x)

Part B:

The volume can be graphed although there must be a domain restriction since the height, width, or length cannot be negative. So let's look at each part of the equation

so for the x in front it must be greater than 0 to make sense

for the (4-2x), the x must be less than 2 or else the width is  negative.

for the (8-2x) the x must be less than 4 or else the length is negative

so the domain is going to be restricted to 0 < x < 2 so all the dimensions are greater than 0

By using a graphing calculator you can see the maximum of the given equation with the domain restrictions is 0.845 which gives a volume of 12.317

What is the domain and range for the following function and its inverse?
Basile [38]

Answer:

"f(x)  

domain: all real numbers, range: all real numbers  

f–1(x)  

domain: all real numbers, range: all real numbers"

Step-by-step explanation:

We can use the fact that the domain of a function and the range of its inverse are equal.

Also, the range of the function and the domain of its inverse are equal as well.

<em>Looking at the function f(x/ = -x + 5, we see that this is a line with a negative slope of 1 and a y-intercept of +5. </em>

As we know from the graph of lines, there is no restricting values in x and y. So for the original function,  domain is the set of all real numbers and the range is the set of all real numbers.

For the inverse, the range is set of all real numbers and domain is also the set of all real numbers.

First answer choice is right.
