Factor x^2-x-30 completely. If the poem polynomial cannot be factored, write “prime” show work

Answers

Answer 1
Answer:

(x+5)(x-6)

Explanation:

The way you can figure this out is by looking at which ones multiply to be 30, but add to be -1. If you were to make a list of what multiplies to be 30, you’d probably do:

30 • 1 = 30
10 • 3 = 30
2 • 15 = 30
5 • 6 = 30

In this case, the best possible answer would be “5 • 6 = 30.” Therefore, you would get:

(x 5)(x 6)

Now, you would have to determine what makes -1. In this case, the answer would be to put a “-“ for 6 and a “+” for 5 because -6 + 5 make -1.

(If you’re still unsure, you can FOIL what you factored.)

Step-by-step explanation:

Consider ΔQST:

Use pythagorus's theorem.

a²=b²+c²

QS²=QT²+ST²

53²=QT²+28²

2809-784=QT²

QT=√2025=45

Consider ΔQRT:

Use pythagorus's theorem.

a²=b²+c²

QR²=QT²+RT²

Row 2: 541

Row 3: 637

2

349 + 4.80n

3

135

Step-by-step explanation:

1

For this, use the equation I gave you above to find the costs.

2

First, the cost of the printer will NOT change, for the number of printers Eddie needs to buy does not change, he only needs one. This already helps you figure out that 349 is not a coefficient to the variable, n. However, when it comes to the number of blank shirts Eddie needs to buy, the number of he gets does change, this is the dependent variable that makes the cost vary. Using the equation above, you can plug in any number.

For example, 20.

349 + 4.80(20) = 445

3

For this final part, I just kept using the equation until I got the closest number that is lower than 1000. In this case, 135 got me 997, and 136 was just a few decimals away from 1000, but it was still over.

3. (1) [tex]y=\frac{1}{4}x[/tex]

4. a) [tex]y=x+6[/tex]   b) [tex]42[/tex]

Step-by-step explanation:

In a proportional relationship, y=2 when x=8, the following lines will show this relationship,

1.   y = 1/4x

2.  y = x - 6

4.  y =  1/2x - 2

What is the equation of line?

The equation of a straight line is a relationship between x and y coordinates, The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept.

Given that,

The point,

x = 8 and  y = 2

We have to check all the given options,

1.   y = 1/4x

     y  = 1/4 × 8

     y  =  2

2.  y   = x - 6

         = 8 - 6

    y   =  2

3.  y   = 4x

         = 4 × 8

    y   = 32

4.  y   = 1/2x - 2

         = 1/2 × 8 - 2

         =  2

Hence, Option 1, 2, & 4 satisfies the given condition

Find the LCM

The LCM of

0,5 is 5.

Greatest common divisor is the largest number which divides two given numbers say 'a' & 'b'

Now let's say a=0 and b= 5

We know that: anything × 0 =0

Therefore 0÷5=0

In other words 5 is a divisor of 0

and 5 is the largest number which divides 5...

Therefore 5 is the greatest common divisor of of 0 and 5Or gcd(5,0)=5

Common divisors of 0 and 5 = 1,5 [0=1*0 ; 5=1*5] and [0=5*0 ; 5=5*1]

We can see that the triangle has at least one similar side and one similar angle. We can also see that the triangles meet at a point, so they must have the same angle at that point where they connect. So that leads us to our answer being ASA since they have two similar angles and one similar side. This is the answer that I think is correct just by looking at the image.

Suzy is competing in a 651 mile long-distance bicycle race. In the first 3 and 1/2 hours she completed 54 and 1/4 miles. If she plans to ride 7 hours per day, how many days will it take for her to complete the race at that pace?

Answers

Answer: 6 days

Step-by-step explanation:

1. Multiply 54 1/4 by 2 (We are multiplying my 2 because 3 1/2 hours is half of 7 hours, so you have to multiply to see how much Suzy rode for 7 hours.

2. Now, divide 651 by the answer you get in step 1 to get your answer (simplify if necessary.)

Answers

Answer: it would be 6

Step-by-step explanation

Delta math

Based on the information for the value of the account to reach $6,020? given it will take 6 years.

Value of account:

Let x represent the number of years

(2.1%×5,300)x+5,300=6,020

111.3x+5,300=6,020

Collect like terms

111.3x=6,020-5,300

111.3x=720

Divide both side by 111.3x

x=720/111.3

x=6 years
