Factoring when a=1 with and without a GCF<br> What is x2+4x-117
quester [9]

Step 1: Make sure that the trinomial is written in the correct order; the trinomial must be written in descending order from highest power to lowest power.

Step 2 : Decide if the three terms have anything in common, called the greatest common factor or GCF. If so, factor out the GCF. Do not forget to include the GCF as part of your final answer.

Step 3 : Multiply the leading coefficient and the constant, that is multiply the first and last numbers together.

Step 4 : List all of the factors from Step 3 and decide which combination of numbers will combine to get the number next to x.

Step 5 : After choosing the correct pair of numbers, you must give each number a sign so that when they are combined they will equal the number next to x and also multiply to equal the number found in Step 3.

Step 6 : Rewrite the original problem with four terms by splitting the middle term into the two numbers chosen in step 5.

Step 7 : Now that the problem is written with four terms, you can factor by grouping.

Pls help with algebra!
Serjik [45]
Part A: This data does represent a function because no value of x is repeated.
Part B: If x = 6 for the relation f(x) = 7x - 15, then f(x) will equal 27. The function f(x) = 7x - 15 will have the greater value
Part C: If f(x) is equal to 6 then x will equal 3

Weekly wages at a certain factory are
SSSSS [86.1K]

Answer:

2.15%

Step-by-step explanation:

If you were to get the z-score for both 500 and 550 and then get the probability of both those z-scores. After getting the probability you would subtract both probability and get your answer.

Z-score:

550-400/2=3

500-400/2=2

Probability:

3 (from the Z-table) is .9987

2 (from the Z-table) is .9772

.9987-.9772= .0215

.0215 as a percentage is 2.15%

Write an equation for the parabola who’s vertex is at (3,6) and which passes through (4,4)
Gekata [30.6K]

Problem

Solution

For this case we know that the vertex is given by (3,6) and the genera equation for a parabola is given by:

y= a(x-h)^2 +k

Where h = 3, k=6 and replacing we have:

y= a(x-3)^2 +6

And we can find the value of a with the point given x= 4, y=4

4= a(4-3)^2 +6

4= a +6

a= 4-6=-2

And the correct equation would be:

d. y= -2(x-3)^2 +6
