Answer:

x = -5 and 1

Step-by-step explanation:

1. Subtract 6 from both sides to get x²+4x-5=0

2. Factor the quadratic equation. Find two numbers that have a sum of 4 and a product of (-5). The numbers 5 and (-1) add to 4 and multiply to get -5

3. The factored equation is (x+5)(x-1)=0

4. Set each factor to equal zero and solve for x.

x+5=0 ... x=-5

x-1=0 ... x=1

Once you know your basic operations addition, subtraction,multiplication, division you will encounter story problems also known as word problems that require you to read a problem and decide which operation to perform in order to get the answer. There are key words here that often indicate which operation you will use. We will give you a list of them, but remember that for many problems there may not be a key word and you’ll have to use your best judgment in order to figure out what to do.

Enter the appropriate value to answer the question or solve the problem.

Licemer1 [7]

Answer:

slope 2.500

x intercept 1.80000

m intercept 4.50000

Step-by-step explanation:

step 1:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

5*(x+4)-(-2*(-4-m)+3)=0

step 2:

-4 - m = -1 • (m + 4)

(5•(x+4))-((0--2•(m+4))+3) = 0

step 3:

5 • (x + 4) - (2m + 11) = 0

step 4:

5x - 2m + 9 = 0

step 5:

Solve 5x-2m+9 = 0

ValentinkaMS [17]

Answer:

y = -(2/3)x - 5

Step-by-step explanation:

y-int = -5

m = rise/run

m = (-5-(-3))/(0-(-3))

m = -(2/3)

therefore,

y = -(2/3)x - 5
