Identify the property used in each step of solving the inequality 3x – 2 > –4.

Answer:

[tex]x=\frac{34z-r}{n}-17[/tex]

Step-by-step explanation:

Given

[tex]n(17+x)=34z-r[/tex]

We have to isolate x on one side of the equation

Dividing both sides by n

[tex]\frac{n(17+x)}{n} =\frac{34z}{n}-\frac{r}{n}[/tex]

Taking LCM on left side

[tex]17+x = \frac{34z-r}{n}[/tex]

Subtracting 17 from both sides

[tex]17+x-17 = \frac{34z-r}{n}-17[/tex]

So, the value of x will be:

[tex]x=\frac{34z-r}{n}-17[/tex] ..

The answer is:

[tex]x=\frac{34z-r}{n}-17[/tex]

To solve for "x" , we just need to isolate it from the equation.

So, we are given the equation:

[tex]n(17+x)=34z-r[/tex]

Then, isolating we have:

[tex]n(17+x)=34z-r\\\\17+x=\frac{34z-r}{n}\\\\x=\frac{34z-r}{n}-17[/tex]

Hence, the answer is:

[tex]x=\frac{34z-r}{n}-17[/tex]

The number line represents the solution to the inequality -2x + 7 > 8, and the solution is x < -0.5.

The filled circle and the arrow pointing left on the number line indicate that the solution to the inequality is to the left of -2.

The inequality that represents this solution is -2x + 7 > 8.

To solve this inequality, we can subtract 7 from both sides to isolate the x variable.

This gives us -2x > 1. Finally, we divide both sides of the inequality by -2, remembering that when we divide by a negative number, the inequality sign flips.

So, the solution to the inequality is x < -0.5.

Thus, Correct option for the given number line is F. -2x + 7 > 8.

Final answer:

The number line indicates the solution to the inequality H. 6x - 9 < -21, where x < -2, including -2 (since the circle is filled). The solution matches the given number line plot.

Explanation:

The number line given indicates the solution to an inequality that includes all numbers to the left of – the filled circle on –2, which means –2 is included in the solution set. This represents an inequality that is of the form x ≤ a where a is –2 in this case. Now let's analyze each of the provided inequalities.

F. -2x + 7 > 8: Solving this we get –x > 1 or x < –1, which does not match the plot.

G. 7x + 11 < 4: Solving this inequality we get x < –1, which also is not a match.

H. 6x - 9 < -21: Resolving this inequality leads to x < –2, which matches the number line.

J. -3x - 15 < -27: Solving this we get x > 4, which is incorrect as per the number line plot.

Therefore, the correct inequality is H. 6x - 9 < -21.

Rent+standard deviation 890+206= $1,096

John's rent: $1,395

Z-score: 1395 - 1096=$299

Answer: 2.4515

Step-by-step explanation:

Given : The mean monthly rent of students at Oxnard University is [tex]\mu=\$890[/tex] with a standard deviation of [tex]\sigma=\$206[/tex]

Using the formula , [tex]z=\dfrac{x-\mu}{\sigma}[/tex], we have the  standardized z-value for x= 1395 as

[tex]z=\dfrac{1395-890}{206}=2.45145631068\approx2.4515\ \text{ [To the nearest four decimal places.]}[/tex]

Hence, the standardized z-score = 2.4515

Step-by-step explanation:

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

[tex]y-y_1=m(x-x_1)[/tex]

m - slope

We have

[tex]m=-\dfrac{1}{3},\ (-6,\ 3)\to x_1=-6,\ y_1=3[/tex]

Substitute:

[tex]y-3=-\dfrac{1}{3}(x-(-6))\\\\y-3=-\dfrac{1}{3}(x+6)[/tex]

Convert to the slope-intercept form

[tex]y=mx+b[/tex]

[tex]y-3=-\dfrac{1}{3}(x+6)[/tex]           use the distributive property

[tex]y-3=-\dfrac{1}{3}x-2[/tex]           add 3 to both sides

[tex]y=-\dfrac{1}{3}x+1[/tex]

Convert to the standard form

[tex]Ax+By=C[/tex]

[tex]y=-\dfrac{1}{3}x+1[/tex]           multiply both sides by 3

[tex]3y=-x+3[/tex]             add x to both sides

[tex]x+3y=3[/tex]

Answer:

Step-by-step explanation:

We have quadratic functions f(x) = ax² + bx + c.

c - y-intercept

If a > 0, then a parabola opens up and has a minimum in a vertex.

If a < 0, then a parabola opens down and has a maximum in a vertex.

The function has maximum and y-intercept of 4:

a < 0 and c = 4

The graph of the function which will have a maximum and a y-intercept of 4 is C. f(x) = x² + 2x + 4.

y intercept is the y coordinate of the point on the line where it touches the Y axis. The x coordinate will be 0 there.

Given are four functions.

We have to find the function which has a y intercept of 4.

This means that substitute x = 0 and then find the value of f(x).

A. f(x) = 4x² + 6x - 1

When x = 0, f(x) = -1 ≠ 4

B. f(x) = -4x² + 8x - 5

When x = 0, f(x) = -5 ≠ 4

C. f(x) = x² + 2x + 4

When x = 0, f(x) = 4

D. f(x) = x² + 4x - 4

When x = 0, f(x) = -4

Hence the function which has a y intercept of 4 is C. f(x) = x² + 2x + 4.

Answer:

The values are a = 5 , b = 3 , h = 0 , k = 3

The equation is x²/9 + (y - 3)²/25 = 1

Step-by-step explanation:

* Lets revise the standard equation of the ellipse

- The standard form of the equation of an ellipse with  center (h , k)

 and major axis parallel to y-axis is (x - h)²/b² + (y - k)²/a² = 1 , where  

-The length of the major axis is 2a  

- The coordinates of the vertices are (h , k ± a)  

- The length of the minor axis is 2b  

- The coordinates of the co-vertices are (h ± b , k)  

- The coordinates of the foci are (h , k ± c), where c² = a² - b²  

* Now lets solve the problem

∵ The vertices of the ellipse along the major axis are (0 , 8) , (0 , -2)

∴ The major axis is the y-axis

∴ The vertices are (h , k + a) and (h , k - a)

∴ h = 0

∴ k + a = 8 ⇒ (1)

∴ k - a = -2 ⇒ (2)

∵ The foci of it located at (0 , 7) , (0 , -1)

∵ The coordinates of the foci are (h , k + c) and (h , k - c)

∴ h = 0

∴ k + c = 7 ⇒ (3)

∴ k - c = -1 ⇒ (4)

- To find k and a add equations (1) and (2)

∴ (k + k) + (a + - a) = (8 + -2)

∴ 2k = 6 ⇒ divide both sides by 2

∴ k = 3

- Substitute the value of k in equation (1) or (2) to find a

∴ 3 + a = 8 ⇒ subtract 3 from both sides

∴ a = 5

- To find the value of c substitute the value of k in equation (3) or (4)

∴ 3 + c = 7 ⇒ subtract 3 from both sides

∴ c = 4

- To find b use the equation c² = a² - b²

∵ a = 5 and c = 4

∴ (4)² = (5)² - a²

∴ 16 = 25 - b² ⇒ subtract 25 from both sides

∴ -9 = -b² ⇒ multiply both sides by -1

∴ b² = 9 ⇒ take √ for both sides

∴ b = 3

* The values are a = 5 , b = 3 , h = 0 , k = 3

* The equation is x²/9 + (y - 3)²/25 = 1

Answer:

a=5, b=3, h=0, k=3

Step-by-step explanation:

The center of the circle is (0,3) therefore h is 0 and k is 3. If you use a graphing calculator and plot the points given you should find that a=5. Then try to c and use the equation c^2=a^2-b^2 to find b.

Answer: By the parallelogram angle theorem, opposite angles of a parallelogram are congruent. Therefore, angle T must be congruent to angle G, and angle G must be congruent to angle L. By the transitive property of congruence, angle T is congruent to angle L.

Step-by-step explanation: This is the sample response on Edge.

Both parallelograms are <L ≅ < T

Because, by the parallelogram angle theorem, opposite angles of a parallelogram are congruent.

Given parallelograms, GHLJ and GSTU such the parallelogram GSTU is inscribed inside parallelogram GHLJ with angle G coinciding on the two parallelograms.

Therefore, angle T must be congruent to angle G, and angle G must be congruent to angle L. By the transitive property of congruence, angle T is congruent to angle L.

Therefore, ∠L ≅ ∠T

A parallelogram is a two-dimensional geometrical shape, whose sides are parallel to each other. It is a type of polygon having four sides (also called quadrilateral), where the pair of parallel sides are equal in length. The Sum of adjacent angles of a parallelogram is equal to 180 degrees.

Parallelograms are shapes that have four sides with two pairs of sides that are parallel. The four shapes that meet the requirements of a parallelogram are square, rectangle, rhombus, and rhomboid.

Rectangles, rhombus, and squares are parallelograms. A trapezoid has at least one pair of parallel sides. The parallel sides are called the bases and the non-parallel sides are called the legs. There are three types of trapezoid - isosceles, right-angled, and scalene trapezoids.

First find the probability on the first roll

The possible results are 1,2,3,4,5,6

evens: 2,4,6

not 2 = 1,3,4,5,6

P(even)=  number of evens/total = 3/6 = 1/2

P (not 2) = number of results not 2/ total = 5/6

Answer:

58 meters

Step-by-step explanation:

We are looking for the length of the base of a triangle, given the height and area. The formula for the area of a triangle  

A=1/2 bh

relates A= the area, b= length of the base, and h= the height of a triangle, so this is the formula we should use.

We are given that the area of the triangle is A=493 and the height h=17. Substitute this information into the formula and solve for b to find

A=493

493=1/2⋅b⋅17

493=17/2b

58=b

The length of the base is 58 meters.

The length of the base of the triangle is 58 meters.

Given,

A triangular flag has an area of 493 square meters and a height of 17 meters.

We need to find what is the length of the base.

The area is given by:

= 1/2 x base x height

Find the area of the triangle.

Area = 493 square meters

Height = 17 meters

Area = 1/2 x base x height

493 square meters = 1/2 x base x 17 meters

Multiply 2 on both sides.

2 x 493 = 2 x 1/2 x base x 17

986  = base x 17

Dividing both sides by 17.

986 / 17 = base

Base = 58 meters.

Thus the length of the base of the triangle is 58 meters.

Answer:

(17+√553)/2

and

(17-√553)/2

Step-by-step explanation:

Subtract 8 from both sides. This leaves you with

sqrt(x-2) = x-8. Square both sides to get rid of the sqrt,

leaving x-2=(x-8)^2

expanding gives x-2=x^2-16x+64

subtract x from both sides leaves

-2=x^2-17x+64

add 2 to both sides

x^2-17x+66=0

this cannot be factored, however, there are other techniques.

Completing the square is a bit annoying, so I will use the quadratic formula, to give the answer.

90=k(3)²

90=k(9)

90=9k

Divide both the sides by 9

k=10

h=kt²

Put the value time (t)=2 in the equation

h=10(2)²

h=10(4)

h=40 meters
