subtract (2y + 3x-x²) from (5x²-y2-2x)

Answers

Answer:

6x² - 5x - y² - 2y

Step-by-step explanation:

We have

5x² - y² - 2x - (2y + 3x - x² ) ← distribute parenthesis by - 1

= 5x² - y² - 2x - 2y - 3x + x² ← collect like terms

= 6x² - 5x - y² - 2y

a woman is 5 times as old as her daughter in 15 years time to be two times as old as her daughter to find a mother's presentsage

Answers

Answer:

25 years.

Step-by-step explanation:

Given that a woman is 5 times as old as her daughter, while in 15 years time it will be two times as old as her daughter, to find a mother's presents age the following calculation must be performed:

5 x 5 = 25

25 + 15 = 40

40/2 = 20

5 + 15 = 20

Thus, the present age of the mother is 25 years, while that of her daughter is 5 years, with which the mother is five times the age of her daughter. In 15 years, the mother will be 40 and her daughter 20, with which she will only be twice her age.

If x and y vary directly and x=25 when y=100 find x when y=24.
PLEASE HELP FASTTTTTTT

Answers

Answer:

x = 6

Step-by-step explanation:

Given that x and y vary directly then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition x = 25 when y = 100 , then

100 = 25k ( divide both sides by 25 )

4 = k

y = 4x ← equation of variation

When y = 24 , then

24 = 4x ( divide both sides by 4 )

6 = x

Find the area of the inner and the outer circles, shown in the figure below. Use 3.14 for pi.

Answers

The radius of the outer circle is 17 so you put that in the formula to find the area of a circle and solve to get 153.86 squared meters as the final answer. The radius of the inner circle is 7 because it shows that the upper part of the circle is 10 and the whole thing is 17, so you do 17-10 to get 7 as the radius. Then put it in the formula and get the final answer as 907.46 squared meters.

Convert the following quadratic equation to vertex form. 2) 3x2 - 12x - 5

Answers

Answer:

2*12x-5

Step-by-step explanation:

In geometry, a vertex form is a point where two or more curves, lines, or edges meet. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedra are vertices. For example, a square has four corners, each is called a vertex.

Exponential functions are used to describe situations where the amount of change is proportional to the amount.

If the amount of change is a constant, then the function is linear.

A. video subscribers change by an amount proportional to their number, so is an exponential function.

B. the change in number of bricks in a row is a constant, so the function is a linear function.

C. The amount of change is proportional to the value, so the function is an exponential function.

Apply the distributive property to simplify the expression 7(11-7).

Answers

Answer:

Step-by-step explanation:

The Distributive property uses the number outside the parenthesis and combines it (using multiplication) with the ones inside.

So, the number 7 will be multiplied with the numbers inside the parenthesis.

7(11-7)

7 × 11 = 77

7 × -7 = -49 (It will just be the same way you multiply but with a added negative sign.)

77-49=

find the variable

Answers

5/x = -9

5 = -9x (we have multiplied x out from the denominator)

5/-9 = x (divided by -9 to isolate x)

Answer:

x = -5/9

Step-by-step explanation:

5/x = -9

multiply by x on both sides

5 = -9/x

multiply by 1/-9 on both sides

-1/9*5 = -1/9 *-9/x

-5/9 = x
