Answer: x=8 or x=-2

Step-by-step explanation:

It would be the first option on the test.

You should subtract 25 on both sides to get this equation x^2-6x-16 in order to factor.  There are three multiplication equations to get to the number 16 which is 1*16, 2*8, and 4*4.  1*16 wouldn't work since you would get either 17, 15 or -15, 4*4 would also not work since you would get +/-8 or 0, which would finalize our two numbers 2 and 8.

Since the c value is negative you would need to get one of your numbers negative which would be -8 since -8 + 2 = -6 which would factor out to (x-8)(x+2).  Subtract -8 and 2 for each x values to get 8 and -2.

x=-2 or x=8 are the  values of x in the equation x²-6x + 9= 25.

A quadratic equation is a second-order polynomial equation in a single variable x , ax2+bx+c=0. with a ≠ 0 .

The given equation is x²-6x + 9= 25

We need to find the values of x.

x²-6x + 9= 25

Let us convert this equation to a quadratic equation.

x²-6x + 9 - 25 = 0

x²-6x -16=0

Now let us factorize the equation

x²-8x+2x -16=0

Take common terms

x(x-8)+2(x-8)=0

(x+2)(x-8)=0

x=-2 or x=8

Hence, x=-2 or x=8 are the  values of x in the equation x²-6x + 9= 25.

Answer:

[tex]\frac{23}{12}[/tex]

Step-by-step explanation:

Start by making a common denominator. In this case, it would be 12.

Multiply -1/3 by 4 to get -4/12

Multiply -9/4 by 3 to get -27/12

Then subtract

- [tex]\frac{4}{12}[/tex] - (- [tex]\frac{27}{12}[/tex] ) =23/12

You can also visualize this on a number line. Once you've made the denominator the same, start at -4/12 and move 27 units to the left to land on 23/12.

4x⁴ = 1 - 3x²

4x⁴ + 3x² - 1 = 0

Factor the left side:

(4x² - 1) (x² + 1) = 0

((2x)² - 1²) (x² - i ²) = 0

(2x + 1) (2x - 1) (x - i ) (x + i ) = 0

Then

2x + 1 = 0   or   2x - 1 = 0   or   x - i = 0   or   x + i = 0

Solve for x :

x = -1/2   or   x = 1/2   or   x = i   or   x = -i

Answer:

The correct option is;

90 degrees counterclockwise rotation

Step-by-step explanation:

The coordinates of the preimage before rotation = K(17, -12)

The coordinate of the image of the preimage after rotation = K'(12, 17)

Therefore, the rotation transformation, transforms, the preimage (x, y) to the image (-y, x), which is equivalent to a rotation of 90 degrees counterclockwise

A salesperson earns 4% commission on furnace sales

The furnace sales have worth $33,000

We need to find the commission that the salesperson earns

∵ The salesperson earns 4% commission on furnaces sale

∵ The furnaces sale have worth $33,000

- Find the 4% of 33,000

∴ The salesperson earns 4% of 33,000

∵ 4% × 33,000 = \frac{4}{100}1004 × 33,000 = 1320

∴ The salesperson earns $1320

The commission that the salesperson earns on the sale is $1320

∵ The salesperson doubles his sales of furnaces

∴ The commission would be double

That because the commission is a constant percent from his sales of furnaces, so if the amount of his sales of furnaces doubles , then his commission also doubles, it is a direct proportion relationship

Commission = constant (4%) × amount of furnaces sale

The commission would be double when he doubles his sales of furnaces

Answer:

80 Grams =

0.08 Kilograms

Step-by-step explanation:

A gram is a unit of weight equal to 1/1000th of a kilogram. A gram is the approximate weight of a cubic centimeter of water.

The kilogram, or kilogram, is the base unit of weight in the Metric system. It is the approximate weight of a cube of water 10 centimeters on a side.

   so basically you divided 80 divided by 10

Answer:

Rosaria purchased 50 bracelets and 70 necklaces

Step-by-step explanation:

Let the number of bracelets be b and the number of necklaces be n

b + n = 120 •••••(i)

Secondly;

10b + 11n = 1270 ••••(ii)

Total cost of b bracelets at 10 per 1 is 10b

Total cost of n bracelets at 11 per 1 is 11n

Adding both gives 1270

From i, b = 120-n

Substitute this into ii

10(120-n) + 11n = 1270

1200 - 10n + 11n = 1270

n = 1270-1200

n = 70

b = 120-n

b = 120-70

b = 50
