Find the value of x. Round to the nearest tenth.

Treat the,, >, or sign as a = sign when graphing an inequality.

Draw a circle over the number to begin plotting an inequality on a number line, such as x>3 (e.g., 3). The circle should be filled in if the sign also includes equal to (or). Leave the circle blank if the sign doesn't contain the equal to symbol (> or ).

By treating the,, >, or sign as a = sign, the inequality can be shown graphically. Make a dotted line graph of the equation if the inequality is either or. Make a solid line out of the equation if the inequality is either or.

Using a straight line and either an open circle or a closed circle to indicate the end points, we can depict inequalities on a number line by displaying the range of integers. The value is not included, as indicated by the open circle. The value is included, as indicated by the closed circle.

The solution set of the system of linear equations represented by the augmented matrix is (x1, x2, x3, x4) = (2, 4, 2, -1)

To determine the values, first express the system of linear equation as represented by the augmented matrix.

The system of linear equations represented by the augmented matrix is:

1x1 + 2x2 + 0x3 + x4 = 3

0x1 + 1x2 + 2x3 + x4 = 3

0x1 + 0x2 + 1x3 + 2x4 = 1

0x1 + 0x2 + 0x3 + 1x4 = 4

By applying row operations to the matrix we can find the solution set

The y-intercept of the expression y=x^2-6x+8 is y(0,8).

What are intercepts?

The term "intercept" refers to the location where a line or curve crosses a graph's axis. The x-intercept is the point at which the x-axis is crossed. The y-intercept is the point at which the y-axis is crossed.

The given expression is -

y = x²-6x+8

To find the y-intercept, substitute the value of x with 0.

y = x²-6x+8

y = (0)²-6(0)+8

y = 8

The system of linear equations y = x - 6.7 and y = - x + 1.7 have solution at point (x, y) = (4.2, - 2.5).

In this problem we need to construct a system of two linear equations whose solution is point (x, y) = (4.2, - 2.5). Linear equations are algebraic equations of the form:

y = m · x + b

Where:

The procedure is shown below. First, obtain the intercept of the first equation:

b = y - m · x

(x = 4.2, y = - 2.5, m = 1)

b = - 2.5 - 4.2

b = - 6.7

Second, write the first linear equation:

y = x - 6.7

Third, find the intercept of the second equation:

b = y - m · x

(x = 4.2, y = - 2.5, m = - 1)

b = - 2.5 - (- 1) · (4.2)

b = - 2.5 + 4.2

b = 1.7

Fourth, write the second linear equation:

y = - x + 1.7

Step 1: Calculate the slant height of the pyramid.

Slant Height = √(6.9^2 + 8^2) = 10.1 cm

Step 2: Calculate the lateral surface area of the pyramid.

Lateral Surface Area = 4 * (1/2 * 6.9 * 10.1) = 176.5 cm^2

Step 3: Calculate the total surface area of the pyramid.

Total Surface Area = Lateral Surface Area + Base Area

Total Surface Area = 176.5 cm^2 + (1/2 * 6.9 * 8) = 227.7 cm^2

The graph of the equation x^2-x-2=3 is a parabola which opens downward.

An equation is a mathematical statement that expresses the equality of two expressions. It consists of two expressions separated by an equals sign (=). Equations are used to express relationships between unknowns, knowns, and constants. Equations are used to solve problems and describe the behavior of systems.

The graph intersects the x-axis at two points, x=1 and x=3.

Therefore, the solutions to the equation are x=1 and x=3.

To find an estimate of the solution, we can draw a straight line from the x-axis to the point of intersection on the parabola.

The line intersects the x-axis at a point slightly higher than x=1, so the estimated solution is x=1.5.

This is an approximate solution and is only an estimate. To find the exact solution, the quadratic formula must be used.

The interest rate on 7,000 for 10 years with a simple interest of 3500 is 5.

Simple interest is the amount paid on a principal amount of money that is borrowed or loaned to someone. It is calculated using the formula: SI = (P × R × T) / 100. Interest Rate (R) is a percent of the principal earned or paid.

From the question;

P = 7,000

T = 10

SI = 3500

we shall evaluate for the rate R as follows:

3500 = (7,000 × R × 10)/ 100

3500 = 70R

divide through by 70

3500/70 = 70R/70

R = 35/7

An Isosceles triangle is a triangle that has two equal sides. Also, the two angles opposite the two equal sides are equal. In other words, we can say that “An isosceles triangle is a triangle which has two congruent sides“.

We have,

∠Q = 8x-17, ∠R = 19x+4, ∠S = 5x+1

So,

∠Q + ∠R + ∠S = 180

= 8x-17 + 19x+4 + 5x+1

= 32x - 12 = 180

= 32x = 192

x = 6

Angles are;

∠Q = 8x-17 = 8(6)-17 = 31

∠R = 19x+4 = 19(6)+4 = 118

a) The sum will be around 100, give or take 10 or so. - True

b) There is about a 68% chance that the sum will be in the range of 90 to 110. - True

a) True. The expected value of a single draw is (0.990)+(0.011)=0.01, and the expected value of 10,000 draws is 0.0110,000=100. The standard deviation of a single draw is the square root of (0.990^2)+(0.011^2)=0.01. So, the standard deviation of 10,000 draws is sqrt(10,0000.01)=10. This means that the sum of 10,000 draws will be around 100, give or take 10 or so.

b) True. The sum of 10,000 draws follows a normal distribution with a mean of 100 and a standard deviation of 10. Using the 68-95-99.7 rule, 68% of the data falls within one standard deviation of the mean. So, the chance that the sum will be in the range of 90 to 110 is 68%.

Part A -   Option B   $382.50

Part B -   11 years

Step-by-step explanation:

The formula for simple interest is

[tex]A=P(1+rt)[/tex]

[tex]A[/tex] is the final amount

[tex]P[/tex] is the initial amount

[tex]r[/tex] is the interest rate as a decimal

[tex]t[/tex] is the time

We are given

[tex]P=3000\\r=0.0425[/tex]

Part A

To evaluate the amount of interest we need to use this equation

[tex]I=Prt[/tex]

[tex]I=3000*0.0425*3[/tex]

[tex]I=382.5[/tex]

Part B

We can start with this equation, but we need to solve for [tex]t[/tex].

[tex]A=P(1+rt)[/tex]

Lets solve for [tex]t[/tex].

Divide both sides of the equation by [tex]P[/tex].

[tex]\frac{A}{P} =1+rt[/tex]

Subtract 1 from both sides of the equation.

[tex]\frac{A}{P}-1 =rt[/tex]

Divide both sides of the equation by [tex]r[/tex].

[tex]\frac{\frac{A}{P}}{r}-\frac{1}{r}=t[/tex]

Simplify the first term by multiplying the numerator by the reciprocal of the denominator.

[tex]\frac{A}{Pr} -\frac{1}{r}=t[/tex]

[tex]t=\frac{A}{Pr} -\frac{1}{r}[/tex]

Now we have an equation for time.

Substituting our values into the equation gives us
