y=kx

10=k15

rearrange the eqn, make k as a subject

k=10/15

k=2/3

Therefore, the answers

y=2/3x

The direct proportion equation that relates x and y is y = 2x/3.

When two quantities are directly proportional it means that if one quantity goes up by a certain percentage, the other quantity goes up by the same percentage as well.

Given that, y is directly proportional to x, when y = 10 when x = 15,

That mean,

y ∝ x

We know the rule of directly proportion,

y = kx

Where k is the proportionality constant,

To find the value of k in the given case, put, x = 15 and y = 10

10 = 15k

k = 2/3

Therefore, we can write,

y = 2/3 x

Hence, the direct proportion equation that relates x and y is y = 2x/3.

Answer:

4 feet or 4/15

Step-by-step explanation:

1. So first you have to multiply the top and bottom number of each fraction by the denominator of the opposite fraction to have the same denominator:

1/3 X 5/5 = 5/15

3/5 X 3/3 = 9/15

2. Then you compare the two fractions and subtract the smaller fraction from the bigger:

9/15 - 5/15 = 4/15

First, you need to choose a yellow marble. That is 6/15.

Next, you need to choose a blue marble. That is 5/14, because 1 yellow marble would have been "chosen" already.

So the probability altogether is 6/15 * 5/14 = 1/7, or about 14%.

Final answer:

The probability of randomly choosing a yellow marble, not replacing it, and then choosing a blue marble can be found by multiplying the probabilities of choosing a yellow marble and a blue marble from the jar.

Explanation:

To find the probability of randomly choosing a yellow marble, not replacing it, and then choosing a blue marble, we first need to find the total number of marbles and the number of favorable outcomes.

There are 5 blue marbles, 6 yellow marbles, and 4 green marbles in the jar, for a total of 15 marbles.

When we choose a yellow marble, there are 6 yellow marbles and 14 remaining marbles. When we choose a blue marble from the remaining marbles, there are 5 blue marbles and 13 remaining marbles.

So, the probability of choosing a yellow marble and then a blue marble is:

(6/15) * (5/14) = 1/7 or approximately 0.14

The number obtained when it is added with 9, multiplied by 3, subtracted by 16 and then added with 7 is 3.

Suppose the number is x

An addition of  9 to x = 9+x

Multiplication of 9+x and 3 = 3(9+x)

According to the question

3(9+x)-16+7 = 27

By solving the above equation we will get x

An equation is a statement that equates to two expressions.

So, 3(9+x) = 36

9+x=12

x=3

So, the number is x=3

Thus, the required number that satisfies the question is 3.

On a number line, a point that is 10 units away from 5 can be either 15 (if you move right) or -5 (if you move left). Both these points are 10 units away from 5.

In mathematics, if the value 5 is plotted on the number line, you can plot another point that is 10 units away from 5 by moving 10 places towards either the right or left on the number line. If you move to the right, 10 places ahead of 5 is 15. So, you can plot a point on 15. On the other hand, if you move to the left, 10 places behind 5 is -5. So, you can plot a point at -5. Either of these points (15 or -5) are 10 units away from 5.

The answer is:

b. [tex]g(x)=x^{2} +3[/tex]

To find what's the equation of the red graph, first, we need to find a function that intercepts the y-axis at 3 and its vertex is located at (0,3)

We must remember that the constant value in a quadratic equation (c) will tell us where the function intercepts the y-axis, so, we are looking for an equation which has a constant value equal to 3, it discards the options a, c and d, so the correct option would be the option b.

Option b function:

[tex]g(x)=x^{2} +3[/tex]

Where,

[tex]a=1\\b=0\\c=3[/tex]

Let's check if the option b is the correct option:

First, let's find the axis intercepts:

Y-axis intercept

[tex]f(x)=x^{2}+3\\f(0)=0^{2}+3\\y=3[/tex]

X-axis intercept

[tex]0=x^{2}+3\\x=\sqrt{-3}[/tex]

There is no x-axis intercepts since the square roots of negative numbers does not exists in the real numbers.

Finding the vertex coordinates:

The x coordinate of the vertex can be found using the following equation:

[tex]x=-\frac{b}{2a}=-\frac{0}{2*1}=0[/tex]

The x coordinate of the vertex is located at x=0, so to find the y-coordinate we must substitute the x value into the parabola equation, so

[tex]y=x^{2}+3=0^{2}+3=3[/tex]

So, the y coordinate of the vertex is located at y=3

Therefore, the vertex of the function is (0,3)

Hence, the calculated values of the option b match with the given graph.

The correct option is: b. [tex]g(x)=x^{2} +3[/tex]

Answer:

Part A. = 2,000,000,000

Step-by-step explanation:

To find the first measurements solve the equation.

10^3 = 1,000

So now 1,000 multiplied by 4

4 x 1,000 = 4,000

for the second side or measurement solve again.

10^5 = 100,000

5 x 100,000 = 500, 000

Answer:

The proportion is true.

Step-by-step explanation:

We are given the following proportion and we are to determine whether it is a true proportion or not:

[tex] \frac { 15 } { 3 } = \frac { y } { 7 } [/tex]

Finding the value of y:

[tex]y = \frac{15}{3} \times 7[/tex]

[tex]y=35[/tex]

So now we have [tex] \frac { 15 } { 3 } = \frac { 35 } { 7 } [/tex]

Checking if it is a true proportion:

[tex] \frac { 15 / 3 } { 3 / 3 } = \frac { 5 } { 1 } [/tex]

[tex] \frac { 35 / 7 } { 7 / 7 } = \frac { 5 } { 1 } [/tex]

Since the simplified fractions are equivalent, therefore the proportion is true.

The given expression, 15/3 = y/7, is a true proportion. Solving for y, we find y = 35.

The given expression, 15/3 = y/7, is a proportion. In a proportion, the product of the means (15 and 7) is equal to the product of the extremes (3 and y). To check if the given proportion is true, we can cross-multiply and check if the products are equal.

Cross-multiplying, we have 15 * 7 = 3 * y. This simplifies to 105 = 3y. Solving for y, we divide both sides of the equation by 3, obtaining y = 35.

Therefore, the proportion is true, and y = 35.
