Find two consecutive integers whose sum is -29
LuckyWell [14K]

Example:

The sum of two consecutive integers is -15.  What is the product of the two integers?

x = 1st consecutive integer

x + 1 = 2nd consecutive integer   {consecutive integers increase by 1}


x + x + 1 = -15   {the sum of two consecutive integers is -15}

2x + 1 = -15   {combined like terms}

2x = -16   {subtracted 1 from each side}

x = -8   {divided each side by 2}

x + 1 = -7   {substituted -8, in for x, into x + 1}


-8 and -7 are the two consecutive integers


Their product is 56.

A linear function is parallel to the line y= 4x + 8 and also goes through the point (2,15).What is the linear equation for this
horrorfan [7]

When written in the y=mx+q form, the slope of a line is given by the coefficient m. Moreover, two lines are parallel if the have the same slope.


Now, the slope of the known line is 4, so our line's slope will be four as well.


In general, when you know the slope m of a line and one of its points (x_0,y_0), the equation of the line can be derived from the following formula:


y-y_0 = m(x-x_0)


Which in your case becomes


y-15 = 4(x-2)


Expand the right hand side and solve for y:


y = 4x+7

What is the radius of a circle with an area of 78.5 cubic inches? Use 3.14 for pi. Enter your answer in the box.
Korvikt [17]

Answer:

r =5 in

Step-by-step explanation:

Area of a circle is given by

A = pi r^2

We know the area and pi

78.5 = 3.14 r^2

Divide by 3.14

78.5/3.14 = 3.14 /3.14 r^2

25 = r^2

Take the square root of each side

sqrt(25) = sqrt(r^2)

5=r
