Which equation represents a line that passes through the two points in the table x 1,5 and y 1,6
aleksandrvk [35]

For this case we must find a linear equation of the form:

y = mx + b

Where,

m: slope of the line

b: cutting point with vertical axis.

For the slope we have the following equation:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}

Substituting values we have:

m = \frac {6-5} {1-1}\\m = \frac {1} {0}

We observe that the slope of the line is not defined.

Therefore, the line is vertical.

Thus, the equation of the line is given by:

x = 1

Answer:

The equation of the line is given by:

x = 1

Mary purchases four book online. The book were the same price each, and the shipping fee was $7.25. If the total cost was $55.25
Sonja [21]

Answer:

The price per book that Mary purchased is $12

Step-by-step explanation:

Mary's total cost can be expressed as;

C=(p×n)+s

where;

C=total cost

p=price per unit of books

n=number of books purchased

s=shipping fee

In our case;

C=$55.25

p=unknown

n=4

s=$7.25

replacing;

55.25=(4×p)+7.25

4 p+7.25=55.25

4 p=55.25-7.25

4 p=48

p=48/4

p=12

The price per book that Mary purchased is $12

Explain how you know 21 over 30 is greater than 2 over 3
Lisa [10]
<span>So we need to explain how we know 21/30 is greater than 2/3. Well lets expand 2/3 by multiplying the numerator and the denumerator by 10. That way we get 20 / 30. Since 21/30 has 1/30 more than 20/30 we can clearly see that 21/30 is greater than 20/30 or 2/3.</span>

What are the solutions to the equation (x-6)(x+8)=0?
Zepler [3.9K]

Answer:

x = 6, -8

Step-by-step explanation:

If (x - 6)(x + 8) = 0, that would imply that either (x - 6) or (x + 8) would equal zero. Using this, we can find that solving the two equations:

x - 6 = 0

and

x + 8 = 0

would yield the two solutions to the equation.

x - 6 = 0

Add 6 to both sides of the equation.

x = 6

So one of the solutions would be x = 6.

x + 8 = 0

Subtract 8 from both sides of the equation.

x = -8

So the other solution would be x = -8.

The two solutions are x = 6 and x = -8.

I hope you find my answer and explanation to be helpful. Happy studying.
