Answer:

[tex]1 + \frac{3}{x} [/tex]

Step-by-step explanation:

1) Rewrite x² - 9 in the form a² - b² where, a = x and b = 3.

[tex] \frac{ {x}^{2} - {3}^{2} }{ {x}^{2} - 3x} [/tex]

2) use difference of squares: a² - b² = ( a + b ) (a - b).

[tex] \frac{(x + 3)(x - 3)}{ {x}^{2} - 3x} [/tex]

3) Factor out the common term x.

[tex] \frac{(x + 3)(x - 3)}{ x(x - 3)} [/tex]

4) Cancle out x - 3 .

[tex] \frac{x + 3}{x} [/tex]

The angle measurements in the diagram are represented by the following expressions.
A = 8x+ 78°
B = 2x + 114
B=

Answers

Since angle A and B are interior angles, we can set them equal to each other. So then we can solve for x and plug x in for B.
1) 8x + 78 = 2x + 114
2) 8x - 2x = 114 - 78
3) 6x = 36
4) 6x / 6 = 36 / 6
5) x = 6
Now we can plug in x to equation b
1) 2(6) +114
2) angle b = 126

A line that includes the point (1, 10) has a slope of 6. What is its equation in slope-intercept
form?

Answers

Answer:

y = 6x + 4

Step-by-step explanation:

The point-slope form of the equation that describes the line with a slope of m and including the point (x₀, y₀) is: y - y₀ = m(x - x₀)

m = 6

(1, 10) ⇒ x₀ = 1, y₀ = 10

Therefore:

y - 10 = 6(x - 1) ← the point-slope form

y - 10 = 6x - 6 {add 10 to both sides}

y = 6x + 4 ← the slope-intercept form

Answer:

C = 39

Step-by-step explanation:

From the question given above, the following data were obtained:

A = 2x + 108

B = x + 33

C =?

Next, we shall obtain an expression for C. This can be obtained as follow:

A + B + C = 180 (sum of angles in a triangle)

2x + 108 + x + 33 + C = 180

2x + x + 108 + 33 + C = 180

3x + 141 + C = 180

Make C the subject by rearranging

C = 180 – 141 – 3x

C = 39 – 3x

Next, we shall determine the value of x. This can be obtained as follow:

A = 2x + 108

B = x + 33

C = 39 – 3x

A + B + C = 180

2x + 108 + x + 33 + 39 – 3x = 180

2x + x – 3x + 108 + 33 + 39 = 180

3x – 3x + 180 = 180

3x – 3x = 180 – 180

3x – 3x = 0

x(3 – 3) = 0

x(0) = 0

x = 0

Finally, we shall determine C. This can be obtained as follow:

C = 39 – 3x

x = 0

C = 39 – 3(0)

C = 39 – 0

C = 39

The measures of the exterior angles of a heptagon are xº, 2x°, 4x°, 6x°, 8x°, 9x°
and 10x°. Solve for x.

Answers

Answer:

the sum of exterior angle of a polygon is always 360 degree.

therefore,

xº+ 2x°+ 4x°+ 6x°+ 8x°+ 9x° +10x° = 360°

40x = 360°

x = 360/40 = 9

x = 9

The sum of the exterior angles of a polygon is 360 degrees, so the value of x is 9

The exterior angles of the polygon are given as:

xº, 2x°, 4x°, 6x°, 8x°, 9x° and 10x°

The exterior angles of a polygon add up to 360 degrees.

So, we have:

[tex]x\º+ 2x\°+ 4x\°+ 6x\°+ 8x\°+ 9x\° +10x\° = 360\°[/tex]

Evaluate like terms

[tex]40x\° = 360\°[/tex]

Divide both sides of the equation by 40

[tex]x\° = \frac{360\°}{40}[/tex]

Divide 360 by 40

[tex]x\° = 9[/tex]

Rewrite as:

[tex]x = 9\°[/tex]

Hence, the value of x is 9

A scientist mixes water (containing no salt) with a solution that contains 35% salt. She wants to obtain 105 ounces of a mixture that is 15% salt. How many ounces of water and how many ounces of the 35% salt solution should she use?

Answers

Answer:

60 oz of water to add

45 oz of 35% salt solution should be used

Step-by-step explanation:

Let x = amt no. ounces in the first solution

and 105 - x = amt no. of ounces in the second solution

Ist solution contains 0% salt

2nd solution contains .35(105 - x) salt

.15(105= amt of salt in mix

So.

amt of salt in 1st solution + amt of salt in 2nd solution = amt of salt in the mix

0 + .35(105 - x) = .15(105)

Let's get rid of the fractions by multipying thru the equation by 100

35(105 - x) = 15(105)

3675 - 35x = 1575

-35x = -2100

x = 60 oz of water to add

105 - 60 = 45 oz of 35% salt solution should be used
