Find the slope of the line through (-1,1) and (3, -4)
jarptica [38.1K]

Answer:

    = -5/4

Step-by-step explanation:

The slope through two points can be found by

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

   = (-4-1)/(3--1)

   = (-4-1)/(3+1)

    = -5/4

A=1/2(b1-b2)h <br><br> Solve for h
Phantasy [73]

Answer:

2A/ (b1-b2) =h

Step-by-step explanation:

A = 1/2 (b1-b2) *h

Multiply each side by 2

2A = 2 *1/2*(b1-b2) *h

2A = (b1-b2) *h

Divide by (b1-b2)

2A/ (b1-b2) = (b1-b2)/(b1-b2) *h

2A/ (b1-b2) =h

How many solutions does the system of equations shown below have?
rjkz [21]

Answer:

one solution with a y value of 5

Step-by-step explanation:

/| x+y-4 = 0| x-y-6 = 0

We try to solve the equation: x+y-4 = 0

x+y-4 = 0 // - x-4

y = -(x-4)

y = 4-x

We insert the solution into one of the initial equations of our system of equations

We get a system of equations:

/| x+x-6-4 = 0| y = 4-x

2*x-10 = 0 // + 10

2*x = 10 // : 2

x = 10/2

x = 5

We insert the solution into one of the initial equations of our system of equations

For y = 4-x:  

y = 4-5

y = -1

We get a system of equations:

/| y = -1| x = 5
