Which is the equation of the perpendicular line?

Emily is 4 times as old as Tiffany. In ten years time, Emily will be twice as old as Tiffany. Find their ages.

\(4x + 10 = 2(x + 10) \\ = 4x + 10 = 2x + 20 \\ = > 4x - 2x = 20 - 10 \\ = > 2x = 10 \\ = > x = \frac{10}{2} \\ = > x = 5\)

Emily's age is 20 years and Tiffany's age is 5 years.

Initial value C is 1.9, Decay factor =0.41 and Growth factor = 0.59 when the function f(x)=1.9(0.41)ˣ.

Given that,

The equation f(x)=1.9(0.41)ˣ.

We have to state the initial value C, the growth or decay factor a, and percent change R for each unit increase in x.

We know that,

In order to translate their graphs over the 2D coordinate plane, I will offer the vertex form of an exponential equation for both the growth and decay functions.

In the case of growth, f(x) = a(1+r\()^{x-h}\)+k, where b = 1+r

Decay is defined as f(x)=a(1-r)(x-h\()^{x-h}\)+k, where b=1-r.

Consider the function  f(x)=1.9(0.41)ˣ.

We write as

f(x)=1.9(1-0.59)ˣ

So, initial value C is 1.9

Decay factor =0.41

Growth factor = 0.59

Therefore, Initial value C is 1.9, Decay factor =0.41 and Growth factor = 0.59 when the function f(x)=1.9(0.41)ˣ.

The baker can only make peanut butter cookies and cannot make any chocolate chip cookies with the given amount of ingredients.

Let's denote the number of batches of peanut butter cookies as "x" and the number of batches of chocolate chip cookies as "y."

From the given information, we can set up the following system of equations:

For the flour:

2x + 3y = 26

For the butter:

34x + y = 9

To solve this system of equations, we can use the substitution method or the elimination method. Let's use the elimination method:

Multiply the first equation by 17 (to make the coefficients of x in both equations the same):

34x + 51y = 442

Now we have the system of equations:

34x + y = 9

34x + 51y = 442

Subtract the first equation from the second equation:

34x + 51y - (34x + y) = 442 - 9

50y = 433

Divide both sides by 50:

y = 433/50

Since the number of batches of cookies cannot be fractional, we need to find a whole number solution for y. However, in this case, y is a fraction, indicating that the given amount of butter is not sufficient to make even one batch of chocolate chip cookies.

The values of x if the two expressions equal are all real numbers.

What is Algebraic expression ?

Algebraic expression can be defined as the combination of variables and constants.

Given expression ,

(x-2) (x+6) / 7 (x+6)  =  x-2/ 7

So, in LHS x+6 can be cancelled

and we get,

=x-2/ 7

which is same as the RHS from the given expression .

So, As the both LHS and RHS are equal , if put any value Both remains same

Hence, The values of x if the two expressions equal are all real numbers.

The graph with the slope of 2 is the second graph.

The slope of a line is a measure of its steepness. The slope of a line is the change in dependent variable with respect to the change in the independent variable.

Therefore, let's find the slope of the graph to know the one with the slope of 2.

Hence,

slope = y₂ - y₁ / x₂ - x₁

Using the second graph,

(-1, -1)(0, 1)

slope = 1 + 1 / 0 + 1

slope = 2 / 1

slope = 2

Therefore, the graph with slope of 2 is the second graph.

The probability that Emily chooses a blue chip and Josie chooses a red chip is 3/28.

Events that are mutually incompatible cannot take place at the same moment. If one thing happens, the other thing can't happen. For instance, if we flip a coin, receiving heads and getting tails are mutually exclusive events. The likelihood of two mutually exclusive occurrences happening simultaneously is zero.

Events that are independent of one another are said to be independent. The likelihood of the other event happening is unaffected if one event happens.

Given, 3 blue chips and 2 red chip from a total of 8 chip we have:

P(Emily chooses blue and Josie chooses red) = P(Emily chooses blue) × P(Josie chooses red after Emily chose blue)

= (3/8) × (2/7)

= 6/56

= 3/28

Hence, the probability that Emily chooses a blue chip and Josie chooses a red chip is 3/28.

Step-by-step explanation:

1 foot= 12 inches

12÷3=4

This means that 1/3 of a foot is 4 inches

5 inches is larger than 4 inches

Answer:

Yes

Step-by-step explanation:

1/3 is 0.33333333333333 foot which  = 4 inches.

Formula: multiply the value in feet by the conversion factor '12'.

So, 0.33333333333333 foot = 0.33333333333333 × 12 = 4 inches.

The other value is 5 inches.

5 inches is greater than 4 inches.
