Find all the whole number solutions to the equation a+b+c+d=15

Allushta [10]

Answer:

a=−b−c−d+15

Step-by-step explanation:

Step 1: Add -b to both sides.

a+b+c+d+−b=15+−b

a+c+d=−b+15

Step 2: Add -c to both sides.

a+c+d+−c=−b+15+−c

a+d=−b−c+15Step 3: Add -d to both sides.

a+d+−d=−b−c+15+−d

a=−b−c−d+15

Which expression could help you find the distance between (10,4) and (-6,4) ?

lina2011 [118]

Answer:

Option D. |10| + |-6|

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

(10,4) and (-6,4)

substitute

$d=\sqrt{(4-4)^{2}+(-6-10)^{2}}$

$d=\sqrt{(0)^{2}+(-16)^{2}}$

$d=16\ units$

therefore

The expression that could help to find the distance is

$|10| + |-6|=10+6=16\ units$

A line that includes the point (0, -2) has a slope of -3. What is its equation in slope-intercept form?

denpristay [2]

Answer:

$y=-3x-2$

Step-by-step explanation:

Equation of straight line in slope intercept form is given as

$y=mx+b$ -------- (1)

Here $m=-3$ and $(x_1, y_1)=(0, -2)$

$y-y_1 = m(x-x_1) \\ y+2 = - 3(x-0) \\ y =-3x-2$ ----------- (2)

Comparing (1) and (2)

m=-3 and b=-2

Equation (2) is equation of straight line with slope -3 and y-intercept -2 in slope intercept form
