Answer:

x squared -3× =x(x-3)

Step-by-step explanation:

Since the common factor is x,one comes out to multiply the other to give it x squared and since one x has been written outside already we just write the 3 so that when we multiply it we will get the answer we were asked to factorise

Answer:

x = 50°

y = 130°

z = 130°

Step-by-step explanation:

the central angle is equal to it's arc in degrees.

y = 180° - 50° = 130°

Answer:

The model is not a good fit

Step-by-step explanation:

The correlation Coefficient is a metric used to evaluate the strength of the relationship between 2 variables, the correlation Coefficient ranges from - 1 to + 1 with values closer to either ±1 depicting the strongwr and better relationship. A value of 0 means no relationship exists and values close to zero means the relationship is weak. Wutb a correlation Coefficient value of 0.02, this value is very close to 0 and hence shows that the relationahip is extremely weak. Hence, the model is not a good fit.

Answer:

x=7

Step-by-step explanation:

8x-5y=16

8x-40=16

8x=56

x=7

143 is the answer.

Step-by-step explanation:

The line that has the 1, and the 37° is a total of 180°.

To find the value of 1, simply subtract 37° from 180°:

[tex]180-37 = 143[/tex]

<1 = 143

Answer:

x=-2

y=5

Step-by-step explanation:

x=28-6y

2x-3y=-19

(substitute the value of x)

2(28-6y)-3y=-19

y=5

x=28-6*5

x=-2

Answer:

717.25 that's the answer

5738 divided by 8 but you only want the R and the R is 2869

Answer:

Pi is the least, then the square root of 10 and then 3.5

Step-by-step explanation:

pi is 3.14, square root of 10 is 3.16 and then 3.5

Answer:

6.4 ft

Step-by-step explanation:

Let “a” be the light post height

Let “b” be the length of the shadow

Let “c” be the distance from the top of the light post to the end of the light post’s  shadow.

Then:

(a X a) + (b X b) = c X c

The Pythagorean Theorem will work pretty well here:

(4 X 4) + (5 X 5) = 16 + 25 = 41

The square root of 41 is: 6.4023

So, about 6.4 ft from the top of the post to the end of the shadow

Answer:

6.4ft

Answer:

x^2 + 5x - 84 = 0

x = 7

Step-by-step explanation:

let the sister's age = y

sister's age (y)  = 5 + x  equation 1

xy = 84  equation 2

Make y the subject of the formula in equation 2

y = 84/x

equate equation 1 and 2

84/x = 5 + x  equation 3

Multiply equation 3 by x

84 = 5x + x^2

x^2 + 5x - 84 = 0

tjis can be solved using quadratic equation

x^2 -7x + 12x -84 = 0

x(x + 12) -7(x + 12)

x = 7 or - 12

age cant be negative so his age is 7

Answer: .618033989 or 618033989/1000000000 or 61% (Not rounded)

Step-by-step explanation:

-1+ (the sign)5 =  1.236067977 and if you divide that by two you get .618033989 or 618033989/1000000000 or 61% (Not rounded)

Answer:                        0.61803398   Or just put 0.6

Step-by-step explanation:

So, you break the randicand up into a product of known factors.

  Or, in other words, find the square root of 5 which is 2.2. Then, you subtract

-1 which gives you ( 2.2 - 1 ) 1.2. Finally, divide by 2 and you final answer is 0.6

Answer:

y=-2(x+8)²-7

Step-by-step explanation:

Given: y=-2x²+5

After transformations: y=-2(x+8)²-7

Vertex would be (h,k) -> (-8,-7) instead of (0,5)

Answer: -6.3 lb after 3.5 hours

Step-by-step explanation:

-1 (4)/(5) = -9/5 = -1.8

0.5hr = -0.9

1hr = -1.8

2hr=-3.6

3hr=-5.4

3.5hr = -6.3

Answer:

x > 9.

Step-by-step explanation:

Here it is just simplifying the inequality.

6 - 2/3x < x - 9

Add 2/3x to both sides.

6 < 5/3x - 9

Add 9 to both sides.

15 < 5/3x

Multiply by 3/5.

9 < x

Flip it.

x > 9.

Answer:

x > 9

Answer:

$1573.50

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year,

then, solving our equation

I = 31470 × 0.05 × 1 = 1573.5

I = $ 1,573.50

The simple interest accumulated

on a principal of $ 31,470.00

at a rate of 5% per year

for 1 year is $ 1,573.50.

Answer:

A red marble

Step-by-step explanation:

First, add all of the possible combinations of marbles that can be picked from the box ( 2 + 2 + 3 + 5 = 12 ). Next, write down the amount of each marble ( 2 purple marbles, 2 blue marbles, 3 green marbles, and 5 red marbles). Then, find the marble that appears most in the box. (red marble). Finally, not only have you found that the red marble is most likely to be picked, you also know the probability of picking a red marble, (5/12).

Answer: red

Step-by-step explanation:

Answer: The answer to this question is measure of angle DGE = 1/2 (measure of arc DGE - measure of arc DE).

Step-by-step explanation:

The formula for an angle outside of the arc can be written as measure of angle x is equal to the larger arc starting from the ends of the segments forming x subtracted to the smaller arc starting from the ends of the segments forming x divided by 2.
