Problem 1

<h3>The slope of the line is undefined </h3>

because this line is completely vertical. All vertical lines have undefined slopes. The x coordinates are both x = p, so there is no change in the x coordinates. Note how the slope formula below leads to a denominator of 0.

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

m = (-a - a)/(p - p)

m = (-2a)/0

We cannot divide by zero, which is why the slope is undefined.

=====================================

Problem 2

<h3>The equation is simply x = p</h3>

The equation of any vertical line is of the form x = k, where k can be replaced with any number or expression. In this case, we replace k with p. Let's say that p = 9. This would mean x = p updates to x = 9; telling us that we have a vertical line through 9 on the x axis.

=====================================

Problem 3

There is no y intercept if p is not equal to zero. This is because any vertical line is parallel to the y axis. Parallel lines never intersect. The y intercept is where the graph crosses the y axis.

If p = 0, then the entire line overlaps the y axis (yielding infinitely many y intercepts); otherwise, if p is nonzero, then there are no y intercepts.

<h3>The answer to part 3 will depend on the status of p being nonzero or not.</h3>

=====================================

Problem 4

<h3>Answer: 0</h3>

The original line is vertical, so any line perpendicular to this original one will be horizontal. All horizontal lines have a slope of zero.

Example: the horizontal line through (2,3) and (7,3) has a slope of zero as the slope formula below shows

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

m = (3-3)/(7-2)

m = 0/5

m = 0

How do I find domain and range from a graph/equation?
likoan [24]

domain represents the x values so for example in a diagonal line that continues infinitely, the domain is all real numbers or (-infinity, infinity)

range represents y values so it would also be all real numbers or (-infinity, infinity)

let’s say there is a line (refer to pic) that moves ONLY from point (-3, -1) and (2, 2)

the domain would be [-3, 2]

we use brackets because it’s a real number unlike infinity (also because it’s a closed circle on the graph; if the graph had an open circle you would use a parenthesis)

and the range would be [-1, 2]

if you have any more questions about this explanation feel free to ask!

Which model represents 2 . 36 ÷ 4 ?Which model represents 2 . 36 ÷ 4 ? A. Three groups each have three tens and 4 ones. B. There
makvit [3.9K]

Answer: C. There are four groups of three tens and six ones

Step-by-step explanation:

From the options,

A. Three groups each have three tens and 4 ones.

Three tens and 4 ones equal: = (3 × 10) + (4 × 1) = 30 + 4 = 34

Therefore, 34 ÷ 3 is incorrect.

B. There are three groups of five tens and 9 ones in each group.

Five tens and 9 ones will be equal to:

= (5 × 10) + (9 × 1)

= 50 + 9 = 59

Therefore, 59 ÷ 3 is incorrect

C. There are four groups of three tens and six ones.

Three tens and six ones equal:

= (3 × 10) + (6 × 1)

= 30 + 6 = 36

Therefore, 36 ÷ 4 is correct

D. There are three groups of five tens and nine ones in each group.

Five tens and nine ones will be equal to:

= (5 × 10) + (9 × 1)

= 50 + 9 = 59

Therefore, 59 ÷ 3 is incorrect

Therefore, the correct option is C.

Answer:

x^{2}-2+\frac{20}{x+7}

Step-by-step explanation:

x + 7) x³ + 7x²- 2x + 6 ( x²- 2

        <u> x³ + 7x²</u>

                     -2x + 6

                     <u>-2x - 14</u>

                           +20

Therefore, we can write the expression in the remainder quotient form as,

x^{2}-2+\frac{20}{x+7}
