the 2 equations that need to be solved are [3x+5] and x-1. If you need the answer to what x is you'd solve it by evening out the problems. so first add one to both so you'd have 3x+6=x then you'd take the 3x and subtract it from both sides making it 6=-2x. Then divide 6 by negative 2 making it -3=x.

The percentage chance of a solution, or essentially its mass/volume percent concentration, with 150 g active ingredient in a total of 1000 mL of solution is 15%.

The student is asking how to calculate the mass/volume percent concentration of a solution with a given amount of active ingredient and total solution volume. To find the percentage concentration, we use the mass of the active ingredient and the total volume of the solution. In this case, it is a 150 g active ingredient in 1000 mL of solution, assumming the solution's density is 1.0 g/mL which is typical for dilute aqueous solutions.

In order to calculate the mass/volume percent (m/v %), we use the formula:

% m/v = (Mass of solute in grams × 100) ÷ Volume of solution in mL

Plugging in the values we get:

% m/v = (150 g × 100) ÷ 1000 mL = 15%

Therefore, the solution has a mass/volume percent concentration of 15%.

Final answer:

The percentage chance of the solution with 150g of active ingredient in a total of 1000mL is 15%.

Explanation:

To calculate the percentage chance of a solution containing 150 g active ingredient in a total of 1000 mL of solution, we use the concept of mass/volume percentage. This concept is often used in chemistry to express the concentration of a solute in a solution.

Assuming the density of the solution is 1.0 g/mL, which is common for dilute aqueous solutions, the total mass of the solution will also be 1000 g.

The mass/volume percentage is hence calculated as:

% m/v = (mass of solute in grams) / (volume of solution in milliliters) x 100%

In this case, it's:

% m/v = (150 g)/(1000 mL) x 100% = 15%

So, the solution has a 15% mass/volume percentage of active ingredient.

Subtract 5 from both sides.

49 - 5 = 44

11q ≤ 44

Divide both sides by 11.

44/11 = 4

q ≤ 4

The answer is q ≤ 4

11q+5 ≤ 49

Subtracting 5 from both sides

11q ≤ 49 - 5

11q ≤ 44

Dividing both sides by 11

q ≤ 4

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.

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

Simplifying

y = 0.25x + 2

Reorder the terms:

y = 2 + 0.25x

Solving

y = 2 + 0.25x

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Simplifying

y = 2 + 0.25x

ANSWER

[tex]x = 6[/tex]

EXPLANATION

The given equation is

[tex] \sqrt{3x + 7} = x - 1[/tex]

We square both sides of the equation to obtain,

[tex](\sqrt{3x + 7} ) ^{2} =( x - 1)^{2} [/tex]

This implies that,

[tex]3x + 7 = {x}^{2} - 2x + 1[/tex]

Rewrite in standard quadratic equation form.

[tex] {x}^{2} - 2x - 3x+ 1 - 7 = 0[/tex]

[tex]{x}^{2} -5x - 6= 0[/tex]

Factor

[tex](x - 6)(x + 1) = 0[/tex]

This implies that,

[tex]x = 6 \: x = - 1[/tex]

We check for extraneous solution by substituting each x-value into the original equation.

When x=-1,

[tex]\sqrt{3( - 1)+ 7} = - 1- 1[/tex]

[tex]\sqrt{4} = - 2[/tex]

2=-2....False

Hence x=-1 is an extraneous solution.

When x=6,

[tex]\sqrt{3( 6)+ 7} = 6- 1[/tex]

[tex]\sqrt{25} = 5[/tex]

5=5 is True.

Hence x=6 is the only solution.

To graph the equation y = -2x - 3, start by plotting the y-intercept at (0, -3) and then use the slope to find more points. Connect these points to form the line.

The given equation is y = -2x - 3. To graph this equation, we can start by plotting the y-intercept, which is -3. This means that the line intersects the y-axis at the point (0, -3). From there, we can use the slope, which is -2, to find more points on the line. For example, when x = 1, y = -2(1) - 3 = -5. So, we can plot another point at (1, -5). By connecting these points, we can draw a straight line that represents the equation y = -2x - 3.

Answer:

Step-by-step explanation:

We want to scale by a factor of 1/10 so |a| = 1/10. This means that the graph is compressed vertically.

We do not reflect across the x axis so a = 1/10.

The new parabola is: y = 1/10 x^2

The new equation of the parabola will be  [tex]y=\frac{x^{2} }{10}[/tex].

The given parabola is:

[tex]y=x^{2}[/tex]

A parabola is a plane curve that is mirror-symmetrical and is approximately U-shaped.

When the parabola y=x² is scaled vertically by a factor of 1/10.

The new equation of parabola will be = [tex]y=\frac{x^{2} }{10}[/tex].

This means the graph of a new parabola will look similar to the previous parabola(symmetric about the origin) but outputs(function values) will be different.

Hence, the new equation of the parabola will be  [tex]y=\frac{x^{2} }{10}[/tex].

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.

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]
