Choose the graph which represents the solution to the inequality:
3x + 8 ≥ 11

Answer:

Step-by-step explanation:

The angular coefficient is a slope.

The slope-intercept form of an equation of a line:

y = mx + b

m - slope

b - y-intercept

We have the equation y = 4 - 2x → y = -2x + 4

The slope is m = -2

Answer:

(x + 7)(x - 3)

Step-by-step explanation:

To factor the quadratic

Consider the factors of the constant term (- 21) which sum to give the coefficient of the x- term (+ 4 )

The factors are + 7 and - 3 since

+ 7 × - 3 = - 21 and + 7 - 3 = + 4, hence

x² + 4x - 21 = (x + 7)(x - 3)

The quadratic equation x^2 + 4x - 21 is factored into (x - 3)(x + 7) where these two factors multiply to -21 and add up to 4.

To completely factor the equation x^2 + 4x - 21, we look for two numbers that multiply to -21 (the c term) and add up to 4 (the b term). The numbers that satisfy these conditions are 7 and -3.

Therefore, the factored form of the equation x^2 + 4x - 21 is: (x - 3)(x + 7) as (x - 3) * (x + 7) gives x^2 + 4x - 21.

Answer:

0.964

Step-by-step explanation:

It's easier to approach this problem if you find the prob. that z is less than -1.8 and then subtract your result from 1.00.

The prob. that z is less than -1.8 can be found using any calculator with probability and statistic functions.

The prob. that z is less than -1.8 = normcdf(-100,-8) = 0.036.  Here "cdf" stands for "cumulative probability density function)," -100 is far to the left of z = -1.8, and the result (0.036) is the area under the standard normal probability density curve to the left of z = -1.8.

Finally, subtract this 0.036 from 1.000, obtaining 0.964.  This is the probability that z is greater than -1.8.

Answer:

1/16

Step-by-step explanation:

1/2 divided by 8= 0.0625

There is not much that can be done to figure out how to write 0.0625 as a fraction, except to literally use what the decimal portion of your number, the .0625, means.

Since there are 4 digits in 0625, the very last digit is the "10000th" decimal place.

So we can just say that .0625 is the same as 0625/10000.

The fraction is not reduced to lowest terms. We can reduce this fraction to lowest

terms by dividing both the numerator and denominator by 625.

Why divide by 625? 625 is the Greatest Common Divisor (GCD)

or Greatest Common Factor (GCF) of the numbers 625 and 10000.

So, this fraction reduced to lowest terms is

Answer:

174 75/142

B

Step-by-step explanation:

Formula

1 coin = Total Mass / number of coins

Givens

Total mass 24783 Ounces (That's awfully heavy. You sure you don't mean grams?)

142 coins

Solution

1 coin = 24783 / 142

1 coin = 174.528169

This is multiple choice so you only have to try one thing. What is 75/142? It turns out that the result is 75/142

75/142 = 0.528169

Another way to do it is to figure out what 174 in whole numbers would weigh:

174 * 142 = 24708

What number is left over? 24783 - 24708 = 75

So the fractional part is 75/142

The area of the circular stained-glass window is 50.24 square yards.

To find the area of the circular stained-glass window, we need to use the formula for the area of a circle: A = πr². Since we know the circumference of the window is 25.12 yards, we can use the formula C = 2πr to solve for the radius. Dividing both sides of the equation by 2π, we get r = C/(2π) = 25.12/(2 × 3.14) = 3.9996 yards. Now we can substitute this value of r into the formula for the area to find the window's area: A = 3.14 × (3.9996)² = 50.24 square yards.

Answer:

64

Step-by-step explanation:

To find the area of the figure, split it into two shapes - a trapezoid and a rectangle.

The area of the trapezoid is found using A = 1/2 (a+b)h. Substitute a = 6, b = 4 and h = 8.

A = 1/2(6+4)(8) = 1/2(10)(8) = 40

The area of a rectangle is found using A = b*h. Substitute b = 6 and h = 4.

A = 6*4 = 24

Together the area adds to 40 + 24 = 64

The type of line of symmetry that the figure has is none.

It is a line, when drawn through a figure, the figure can be folded along the line of symmetry and both sides would coincide.

The given figure is a parallelogram.

It does not have a vertical line of symmetry, because when we fold the figure, both sides of the figure won't coincide.

It does not have a horizontal line of symmetry, because when we fold the figure, both sides of the figure won't coincide.

It does not have a diagonal line of symmetry, because when we fold the figure, both sides of the figure won't coincide.

Therefore, the given figure has no lines of symmetry. The correct answer is option D.

9 + 3c = 36

3c = 27

c = 9

x = 3 + 9

x = 12

Answer:

The answer is x=12

Step-by-step explanation:

In order to determine the "x" value, we have to know about the tangent to a circle.

The line that joins two infinitely close points from a point on the circle is a Tangent. It means, the lines that intersect the circles exactly in one single point are tangents.

I have attached an image that shows a tangent to a circle. Also there is a formula that relates the segments of the circle.

According to the same notation of the image:

[tex]PS^2=PQ*PR[/tex]

In this case:

[tex]PS=6\\PQ=3\\PR=x\\6^2=3*x\\x=\frac{36}{3}=12[/tex]

53 add the 2 and you get 8

Step-by-step explanation:flip them 35 + 18 =53

Answer:

53

Step-by-step explanation:

 Let x = the first digit

and y = the second digit. Then,

    xy = the number

We have two conditions:

(1) x + y = 8

(2) 10y + x = 10x + y - 18

Simplify (2)                     10y + x - 10x - y = -18

                                              (3) 9y - 9x  = -18

Multiply Equation (1) by 9     (4) 9x + 9y =  72

Add Equations (3) and (4)                18y =  54

Divide each side by 18         (5)           y =    3

Substitute (5) into (1)                       x + 3 =   8

Subtract 3 from each side                   x =   5

x = 5 and y = 3

The number is 53.

Check:

(1) 5 + 3 = 8     (2) 10×3 + 5 = 10×5 + 3 - 18

         8 = 8             30  + 5 =   50  + 3 - 18

                                      35 =       53    - 18

                                      35 =            35

Step-by-step explanation:

The formula of an area of a circle:

r - radius

We have A = 615.44 in². Substitute:

[tex]615.44=\pi r^2[/tex]

[tex]\pi\approx3.14[/tex]

[tex]3.14r^2=615.44[/tex]          divide both sides by 3.14

[tex]r^2=196\to r=\sqrt{196}\\\\r=14\ in[/tex]

The formula of a circumference of the circle:

Answer: Option a.

Step-by-step explanation:

1. Multiply the numerator and the denominator of the expression shown in the image, by the conjugate of the denominator ( [tex]\sqrt{x}-\sqrt{7}[/tex]), as you can see below:

[tex]\frac{(\sqrt{x})(\sqrt{x}-\sqrt{7})}{(\sqrt{x}+\sqrt{7})(\sqrt{x}-\sqrt{7})}[/tex]

2. By definition, you know that:

[tex](a+b)(a-b)=a^2-b^2[/tex]

3. Therefore, you obtain the following result:

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

Then, the answer is option a.

The answer is:

a. [tex]\frac{x-\sqrt{7x}}{x-7}[/tex]

Rationalizing involves eliminating or the roots of both numerator and denominators, there are severals ways to do it but one of the most common methods is using the conjugate term.

We must remember that:

[tex](a-b)(a+b)=a^{2}-b^{2}[/tex]

So, for the given expression:

[tex]\frac{\sqrt{x}}{\sqrt{x}+\sqrt{7}}[/tex]

The conjugate is:

[tex]\sqrt{x}-\sqrt{7}[/tex]

The, we need to multiply both numerator and denominator (in order to not affect the expression) by the conjugate expression in order to eliminate the radicals in the denominator:

[tex]\frac{\sqrt{x}}{\sqrt{x}+\sqrt{7}}*\frac{\sqrt{x}-\sqrt{7}}{\sqrt{x}-\sqrt{7}}=\frac{(\sqrt{x})*(\sqrt{x}-\sqrt{7})}{(\sqrt{x}+\sqrt{7})*(\sqrt{x}-\sqrt{7})}[/tex]

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

[tex]\frac{(\sqrt{x})^{2}-(\sqrt{x})*(\sqrt{7})}{(\sqrt{x})^{2}-(\sqrt{7})^{2}}=\frac{x-\sqrt{7x}}{x-7}[/tex]
