For the rectangle given, considering its diagonal properties, the value of x=4, while the angle VUR=36°

To answer this question, let us recall the following:

Hence;

the lengths RV and SV are

so, 3x+8=6x-4

6x-3x=8+4 [collecting like terms]

3x=12

when we divide both sides of the equation by 3, we have the value of x=4.

the angles VRS and VRU are complementary

so, 54°+VRU = 90°

VRU = 90°-54°

VRU = 36°

The triangle RUV is an Isosceles

so, angles VRU and VUR are equal, therefore angle VUR = 36°.

We can reduce from our workings that the value of x = 4 and the angle VUR is 36°.

Given,

Ali buys 2 comic books a week.

After 5 weeks he has 17 comic books this year.

Solution:

Let w be weeks and c be comic books.

Since Ali buys 2 comic books a week.

1w = 2c

For 5 weeks, he would have,

5w = 10c, if he bought 2books per week.

But he had 17 books,

i.e, he would have collected some books last year.

Let x be the no of unknown weeks last year.

(x + 5)w = 17c

(x+5)w-17c= 0

xw + 5w - 17 = 0 is the required equation.

A) The slope represents the probability of winning for each rank.

B) The y-intercept means the probability of winning for an unranked school.

C) The probability of winning for a school ranked number 4 is; 78%

The formula representing the general form of an equation in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

A) From the given graph, we see that the y-axis represents the probability of winning for each rank while the x-axis represents the ranks of the schools. Thus;

Slope unit = Probability of winning/Rank

B) The y-intercept is the point at which the graph crosses the y-axis. In this case, it means no ranked school and that is the probability of winning for an unranked school.

C) The linear equation is given by the formula;

y = -6.4x + 103.8

Thus, for a rank of 4, we have;

y = -6.4(4) + 103.8

y = 78.2 ≈ 78%

The system of equations has two solutions, these are:

(-0.89, 2.33) and (1.4, 9.2)

Here we have the following system of equations:

y = 3x + 5

y = 4x² + x

We can see that y is already isolated in both equations, so we can write the equation:

3x + 5 = y = 4x² + x

3x + 5 = 4x² + x

now we can solve this for x, this is just a quadratic equation:

3x + 5 - 4x² - x = 0

-4x² + 2x + 5 = 0

Using the quadratic formula, we can see that the two solutions are:

[tex]x = \frac{-2 \pm \sqrt{2^2 - 4*(-4)*5} }{2*-4} \\\\x = \frac{-2 \pm 9.17}{-8}[/tex]

So the solutions are:

x = (-2 +9.17)/-8 = -0.89

x = (-2 - 9.17)/-8 = 1.4

Evaluating the linear equation in these values, we get:

y = 3*(-0.89) +5 = 2.33

y = 3*(1.4) + 5 = 9.2

So the solutions of the system are:

(-0.89, 2.33) and (1.4, 9.2)

There were twice as many sapodillas as paw paws--take the sapodillas as 2 units and paw paws as 1 unit.

Form an equation.

2u + 1u + 82 = 250

Simplify and solve for 1 unit.

3u = 168

1u = 56

Number of paw paws is 56.

Formula for finding percentage of an object is given as (number of object/total number of items) x 100.

Percentage of paw paws

The single inequality y > |x + 2| is equivalent to:

4. y > x + 2

y < –x – 2

It should be noted that an inequality is simply used to show the relationship between the expressions that aren't equal.

The non-negative value of a real number x, regardless of its sign, is its absolute value or modulus | x |. For instance, 5 has an absolute value of 5, and 5 has a value of 5. One way to think about a number's absolute value is as its distance from zero on the real number line.

It should be noted that based on the information, the inequality is:

y > |x + 2|. This is the positive part of the modulus.

This is the same as y < –x – 2 when the signs are changed. This is the negative part of the modulus.

In conclusion, the correct option is 4.

Using the sales tax, the amount of money she still needs is $5.72

A sales tax is a consumption tax imposed by the government on the sale of goods and services.

Jane wants to buy a CD for $12. She has saved $7.

The amount she needs if 6% sales tax is added to the cost can be calculated as follows;

Let's find the sales tax,

sales tax = 6% of 12

sales tax = 6 / 100 × 12

sales tax = 72 / 100

sales tax = $0.72

Therefore,

amount she needs to save = 12 + 0.72 - 7

amount she needs to save = 12.72 - 7
