Answer:

4^2 * 4^8 = B)4^10

Step-by-step explanation:

When multiplying numbers with exponents, you will always add the exponents together. Therefore, 2+8=10 which is 4^10. You can also simplify the numbers and multiply them together. For example, 4^2=16 and 4^8=65,536 and when u multiply those numbers you get 1,048,576. The one that matches is 4^10=1,048,576.

Let's give Cindy's age a variable.

Cindy's age = x

Cindy multiplies her age by 5

x(5)

Subtracted by 12

x(5) - 12

Divide by 3

(5x - 12)/3

The result was 16

(5x - 12)/3 = 16

Let's solve

Multiply both sides by 3

(5x - 12) = 48

Open brackets

5x - 12 = 48

Add 12 to both sides

5x = 60

Divide by 5 on both sides to isolate x

x = 12

Cindy is 12 years old.

Answer:

-7

Step-by-step explanation:

The line (y-1)=(2/3)(x+1) contains point (a,-3)

=> (-3-1) = (⅔)(a+1)

-4 = (⅔)(a+1(

(a+1)= -4 ÷ ⅔

a + 1 = -4 × 3/2

a+ 1 = -6

a = -6-1

a = -7

The value of 'a' will be;

⇒ a = - 7.

To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

Given that;

The equation of line is,

⇒ (y - 1) = (2/3) (x + 1)

And, The point on the line = (a, - 3)

Now,

Since, The point on the line = (a, - 3)

Hence, It satisfy the equation of line.

Substitute x = a and y = - 3, we get;

⇒ (y - 1) = (2/3) (x + 1)

⇒ (- 3 - 1) = (2/3) (a + 1)

⇒ - 4 × 3 = 2a + 2

⇒ - 12 - 2 = 2a

⇒ 2a = - 14

⇒ a = - 7

Thus, The value of a = - 7

Answer:

y=3

Step-by-step explanation:

6=2(y+2)-4

6=2y+4-4

6-4+4=2y

6=2y

3=y

The answer you are looking for is y=3.

Solution/Explanation:

First, writing out the problem,

6=2(y+2)-4.

Next, using the Distributive Property for 2(y+2), which is 2y+4,

6=2y+4-4.

Now, canceling out the 4, since 4-4=0,

6=2y+0, or 6=2y.

Finally, dividing both sides by 2,

6/2=2y/2.

6/2=3.

2y/2=y.

3=y, or y=3.

So, therefore, the final answer is y=3.

I hope that this has helped answer your question. Good day to you.

Answer:

y = [tex]\frac{ac}{a-b-c}[/tex]

Step-by-step explanation:

Given

y(a - b) = c(y + a) ← distribute parenthesis on both sides

ay - by = cy + ac ( subtract cy from both sides )

ay - by - cy = ac ← factor out y from each term on the left side

y(a - b - c) = ac ← divide both sides by a - b - c

y = [tex]\frac{ac}{a-b-c}[/tex]

The value of y is ac/ (a-b-c)

An equation in math is an equality relationship between two expressions written on both sides of the equal to sign.

For example, 3y = 16 is an equation.

Given equation:

y(a-b)=c(y+a)

Now, using distributive property

ay-by = cy + ac

ay-by-cy = ac

y(a-b-c)=ac

y= ac/ (a-b-c)

Hence, the value of y is ac/ (a-b-c).

Answer:

  21 square units

Step-by-step explanation:

The formula for the area of a parallelogram is ...

  A = bh

where h is the height measured perpendicular to the base.

Here, it is convenient to use the horizontal dimension as the height, and the vertical dimension as the base. The vertical bases are 3 units long and 7 units apart horizontally.

If a segment XZ joining two endpoints X[tex](x_1,y_1)[/tex] and Z[tex](x_2,y_2)[/tex] is divided by a point Y(x, y) externally in the ratio of m : n,

Coordinates of the point will be,

x - coordinates → [tex]\frac{mx_2-nx_1}{m-n}[/tex]

y - coordinates → [tex]\frac{my_2-ny_1}{m-n}[/tex]

If the coordinates of the endpoints X and Z are (1, 9) and (5, -11) respectively and the ratio in which a point Y divides the segment is 1 : 5,

(Since, XY : XZ = 1 : 4 therefore, XY : YZ = 1 : 5)

Therefore, coordinates of Y will be,

x- coordinates → [tex]\frac{1(5)-5(1)}{1-4}=0[/tex]

y-coordinates → [tex]\frac{1(-11)-5(9)}{1-5}=\frac{-56}{-4}=14[/tex]

Therefore, coordinates of Y will be [tex](0,14)[/tex].
