Answer:

x = 8

Step-by-step explanation:

4x = 32

Divide each side by 4

4x/4 = 32/4

x = 8

The solution to the equation 4x = 32 is x = 8.

In order to evaluate and solve this equation, we would have to apply the PEMDAS rule, where mathematical operations within the parenthesis (grouping symbols) are first of all evaluated, followed by exponent, and then multiplication or division from the left side of the equation to the right.

Lastly, the mathematical operations of addition or subtraction would be performed from left to right.

Based on the information provided, we have the following mathematical equation:

4x = 32

By dividing both sides of the equation by 4, we have:

x = 32/4

x = 8

Answer:

28 ways

Step-by-step explanation:

After placing 1 ball in each of the seven bins, there are two balls left.

If we place both balls in a single bin, there are 7 different ways to place the balls (place both on bins 1 through 7).

If we place each of the remaining balls in a different bin, the number of ways to place the balls is:

[tex]n_2=\frac{7!}{(7-2)!2!}=7*3=21[/tex]

The total number of ways to distribute those balls is 21 + 7 = 28 ways.

Answer:

0.008.

Step-by-step explanation:

10^-3 basically tells you to move the decimal point to the left by three digits.

Right now, you have 8. If the decimal point were to move left by three digits, you can visualize 8 as 0008. Move left by three digits, and you get 0.008.

Hope this kind of helps!

Answer:

0.008.

Answer:

Vertex:   ( 1 ,  9 )

Y-intercept:   ( 0 ,  8 )

Step-by-step explanation:

y = - (x+2) (x-4)

y = -x² + 2x + 8

Find the vertex.

x = -b/2a

x = -2/2(-1)

x = -2/-2

x = 1

y = -(1)² + 2(1) + 8

y = -1 + 2 + 8

y = 9

Find the y-intercept.

Put x as 0.

y = -(0)² + 2(0) + 8

y = 8

Step-by-step explanation:Answer:a

Step-by-step explanation:horizonal line test can tell if it is a function or not.if we get more than one value of y for a value of x then it is not a function. In the option (a) we get +2and -2 for x=0

Answer: 72 cm²

Step-by-step explanation: lets take the width as x and length as 2x as length is twice the width= perimeter of rectangle is 2*(l+b)=36cm

So, 2×(2x+x)=36cm

2×3x=36cm

6x=36cm

X=36/6:6cm( width, since width was taken as x)

Length= 2x: 2×6=12cm

So area of the rectangle is( l*b):

12×6= 72cm²

Answer:

7∠82°

Step-by-step explanation:

Well angle 6 and 7 are complementary angles, meaning they both add up to 180°.

So we do 180 - 98 which is 82°.

Answer: The measure of angle 7 is 82 degrees.

Step-by-step explanation:

Angle  6 and 7  lies on a straight line so they will add up to 180 degrees.

So if Angle 6 is 98 degrees then an a number plus 98 has to equal 180.

so we could generate an equation as x + 98 = 180  

x + 98 = 180 solve for x

 -98      -98

x= 82  

Answer:

a. two (distinct) real solutions.

c = 3, x=¨{-1,-3}

b. two complex solutions

c = 17, x={-2+sqrt(13)i, -2-sqrt(13)i}

c. two coincident roots (i.e. one real solution)

c=4, x = {-2}, or x = {-2, -2}

Step-by-step explanation:

Given:

x^2+4x+c =0

a. two (distinct) real solutions.

c = 3

(x+1)(x+3) = 0

x=¨{-1,-3}

b. two complex solutions

c = 17

x^2+4x+17=0

does not have real factors.

x={-2+sqrt(13)i, -2-sqrt(13)i}

c. two coincident roots (i.e. one real solution)

c=4

x^2+4x+4=0 => (x+2)^2 = 0 => perfect square

x = {-2}, or x = {-2, -2}

Answer:

DB=BK

Step-by-step explanation:

Answer:

192 - 4√291341371

Step-by-step explanation:

If your question is: 192 - √83(√643)(√106)(√824) - √0

Then you multiply all the √s together and then subtract it from 192. √0 is 0, so you don't have to worry about that.

If your question is to simplify 192 in √ form, then the answer is none of the above. To find the √ form of 192, square it: 192² = 36864. So to simplify 192 in √ form, it would be √36864.

Answer:

(-3, 5), (1, 4), (-2, 3), and (0, 2).

Step-by-step explanation:

When a function is inverted, the x-values become y-values, and the y-values become x-values.

The ordered pairs for the function are (5, -3), (4, 1), (3, -2), and (2, 0).

After inversion, the ordered pairs will be (-3, 5), (1, 4), (-2, 3), and (0, 2).

Hey there! :)

Answer:

x = -7/12.

Step-by-step explanation:

Given:

[tex]x + \frac{5}{12} = -\frac{1}{6}[/tex]

Create a common denominator for each term:

[tex]\frac{12x}{12} + \frac{5}{12} = -\frac{2}{12}[/tex]

Disregard the denominator:

12x + 5 = -2

Subtract 5 from both sides:

12x = -7

Divide both sides by 12:

x = -7/12.

Answer:

y = 4x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 4, thus

y = 4x + c ← is the partial equation

To find c substitute (1, 7) into the partial equation

7 = 4 + c ⇒ c = 7 - 4 = 3

y = 4x + 3 ← equation of line

Answer:

The equation is y = 4x+3

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b where m is the slope and b is the y intercept

y = 4x + b

Substitute the x and y value into the equation

7 = 4(1)+b

7 = 4+b

Subtract 4

7-4 =b

3=b

The equation is y = 4x+3

Answer:

-3.125  <   -2.95    <    2.6     <     103.5

Step-by-step explanation:

1) [tex]5\frac{6}{15}- 2\frac{4}{5}[/tex]

=> [tex]\frac{39}{15}[/tex]

=> 2.6

2) -4.5 * -2.3

=> 103.5

3) [tex]\frac{5}{-1.6}[/tex]

=> -3.125

4) [tex]-\frac{33}{10} + \frac{7}{20}[/tex]

=> [tex]\frac{-66+7}{20}[/tex]

Answer:

x = 5

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

Here b = x + 3 and h = 2x - 5 , thus

[tex]\frac{1}{2}[/tex] (x + 3)(2x - 5) = 20 ( multiply both sides by 2 )

(x + 3)(2x - 5) = 40 ← expand factors on left using FOIL

2x² + x - 15 = 40 ( subtract 40 from both sides )

2x² + x - 55 = 0 ← in standard form

(x - 5)(2x + 11) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 5 = 0 ⇒ x = 5

2x + 11 = 0 ⇒ 2x = - 11 ⇒ x = - 5.5

But x > 0 , hence x = 5

Answer:

1. [tex]xy = 63[/tex]

2. [tex]y = 3[/tex]

Step-by-step explanation:

Given

Variation: inverse Proportion

y = 7, x = 9

Required

- Write an equation connecting y and x

- Find y when x = 21

Given that thee variation is inversely proportional;

This implies that

[tex]y\ \alpha\ \frac{1}{x}[/tex]

Convert variation to equation

[tex]y\ = \frac{k}{x}[/tex] ----------- Equation 1

Where k is the constant of variation

Substitute 7 for y and 9 for x in equation 1

[tex]7 = \frac{k}{9}[/tex]

Multiply both sides by 9

[tex]9 * 7 = 9 * \frac{k}{9}[/tex]

[tex]63 = k[/tex]

Substitute 63 for k in equation 1

[tex]y = \frac{63}{x}[/tex]

Multiply both sides by x

[tex]x * y = \frac{63}{x} * x[/tex]

[tex]xy = 63[/tex]

Hence, the equation connecting x and y is [tex]xy = 63[/tex]

Solving for when x = 21

Substitute 21 for x in the above equation

[tex]21 * y = 63[/tex]

Divide both sides by 21

[tex]\frac{21 * y}{21} = \frac{63}{21}[/tex]

[tex]y = 3[/tex]
