how to find the vertex

In class 7, a solution is typically defined as a type of mixture where one or more substances are evenly dispersed in another substance.

The substance that is being dispersed is called the solute, and the substance that it is being dispersed in is called the solvent. Solutions can be liquids, gases, or even solids, and they can be formed by dissolving a solute in a solvent.

In class 7, students learn about different types of solutions, such as:

Liquid solutions: These are solutions where the solvent is a liquid, such as sugar dissolved in water to make a sweet drink.

Gas solutions: These are solutions where the solvent is a gas, such as air, and the solute is a gas or a solid, such as the dissolved oxygen in the air we breathe.

Solid solutions: These are solutions where the solvent is a solid, such as a metal alloy, and the solute is a metal or a non-metal.

The equation will equal 13 if the value of x is 2.

A word puzzle states that Shiya has 10 balls and Riya has 3 more than Tom. How many balls does Ria possess?

Let x represent the quantity of Balls Shiya owns.

Shiya has 10 Balls, thus x is equal to 10, and Ry has x+3 Balls.

As a result, Riya has = x + 3 = 10 + 3 = 13 Balls.

Therefore, Riya has 13 Balls total.

If the spinner is fair, it means that the probability of the arrow stopping on any given color is the same. Given that there are four colors on the spinner (green, blue, purple, and yellow), we can expect the arrow to stop on green 1/4 of the time. So if the spinner is spun 300 times, we would expect the arrow to stop on green 300 times * 1/4 = 75 times.

Given that the spinner has been spun once more, the table now shows that the spinner has been spun 301 times. We can estimate the probability of it landing on purple by using the number of times it has landed on purple divided by the total number of spins.

Purple: 48/301 = 0.159 or 15.9%

If the spinner is spun another 1000 times, we can expect it to land on blue 1000 * 1/4 = 250 times approximately, this is assuming the spinner is fair.

It is a horizontal line which crosses the y axis at -4

The y-intercept is the point at which the graph crosses the y-axis. The most important step in graphing any function with the formula y = f(x) is finding the intercepts. The x-intercept and the y-intercept are the two possible forms of an intercept for a function. The point on the axis where a function's graph intersects it is known as the intercept.

In this equation, y=-4 which means y-intercept is -4 (i.e., c= -4) and the slope of the line is 0.

Thus, it will be a horizontal line cutting the y-axis at -4

The domain of a function is the set of all input values (or independent variables) for which the function is defined, and for which the output values (or dependent variables) are real numbers. In other words, it's the set of all the values that can be plugged into the function without resulting in an error.

The number 7 is not a function, it's a constant value. Therefore, it doesn't have a domain, as it doesn't take any input value. A domain is only applicable for a function, which takes some input and produces an output. It does not make sense to speak of the domain of a constant number.

In contrast, if you have a function like f(x) = 7, the domain of this function would be the set of all real numbers since the function will produce the output of 7 for any real value of x.

The person who drink more water is Troy and he drinks 0.3 L more than Whitney

It is the transformation of a value expressed in one unit of measurement into an equivalent value expressed in another unit of measurement of the same nature.

To solve this problem, we have to do the conversion of units with the given information:

Information about the problem:

By converting the unit from mL to L, we have:

1500 mL * (1 L / 1000 mL ) = 1.5 L

Comparing the volume of water that Whitney and Troy drink we have:

1.8 L > 1.5 L

Troy > Whitney

Troy drinks more water than Whitney

Calculating how much water Troy drinks more, we get:

Volume difference = Troy - Whitney

Volume difference = 1.8 L - 1.5 L

Volume difference = 0.3 L

The number of solutions to an equation x₁ + x₂ + x₃ = 11 are 55

Consider given equation x₁ + x₂ + x₃ = 11,

wherex₁, x₂, and x₃ are non-negative integers.

We can oberve that x₁ is the number of ones before the first zero, x₂ the number of ones between the first and the second zero, x₃ is the number of ones after the second zero.

So, we can say that there is a one to one correspondence between the solutions and reorderings of 11 ones and 2 zeros.

So, the number of solutions to given equation would be,

n = ¹¹C₂

Using combination formula [tex]^nC_r=\frac{n!}{r!\times(n-r)!}[/tex],

¹¹C₂ = 11! / (2! × (11 - 2)!)

Coupon 1 will provide more discount and hence he will use coupon 1.

Percent discount is a way to express a reduction in price as a percentage of the original price. It is commonly used in sales and promotions. For example, a 20% discount on a $100 item would reduce the price to $80.

In order to check which coupon provides more discount to the Margaret we need to check for both coupon value and the coupon whose value is greater that one we will use

coupon 1 is 15 percent of initial cost.

Coupon 1 value = (15/100) * 275

The process of multiplying a number or expression by itself a certain number of times, known as its exponent.

1) 3a + 6 = 5a

3a + 6 - 5a = 0

-2a = 0

a = 0

2) 5c - 4c = c

5c - 4c - c = 0

c = 0

3) 8x8 - 4x - 3 = 16% - 7

8x8 - 4x - 3 - 16% + 7 = 0

64x - 3 - 16% = 0

64x - 3 - 16/100 = 0

64x - 0.16 = 0

64x = 0.16

x = 0.0025

Exponents are a way to represent repeated multiplication of a number by itself. To solve an equation with an exponent, we must simplify the expression by breaking down the exponent into its component parts, and then simplify the equation by solving for the variable. We can then solve for the exponent by substituting the value of the variable into the equation. For example, if we had an equation of 3a + 6 = 5a, we would first subtract 5a from both sides to get -2a = 0. We can then substitute that value into the equation to get a = 0. Exponents can be a useful tool to quickly solve equations, but can also be tricky to solve if you don't know the basics of algebra.
