[tex]5x + 2y = 19[/tex]

Subtract sides 5x

[tex] - 5x + 5x + 2y = - 5x + 19[/tex]

[tex]2y = - 5x + 19[/tex]

Divide sides by 2

[tex] \frac{2y}{2} = \frac{ - 5x + 19}{2} \\ [/tex]

[tex]y = \frac{ - 5x}{2} + \frac{19}{2} \\ [/tex]

[tex]y = - \frac{5}{2} x + \frac{19}{2} \\ [/tex]

The solution of the equation 5x + 2y = 19 for the value of y is y = (-5 / 2)x + ( 19 / 2).

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given expression is 5x + 2y = 19. The value of y will be calculated as:-

5x + 2y = 19

2y = 19 - 5x

y = ( 19 / 2 ) - ( 5x / 2 )

Therefore,  the solution of the equation 5x + 2y = 19 for the value of y is y = (-5 / 2)x + ( 19 / 2).

Answer:

70% of the students are enrolled in health class.

Step-by-step explanation:

We are given that there are 70 students enrolled in health and that 30 are not. Therefore, we need to determine the total number of students in Oscar's grade.

[tex]70 + 30 = 100[/tex]

Oscar has 100 students in his grade. If 70 of those students are enrolled in health, we can divide those students by the total number of students and convert our fraction to a decimal and then a percentage.

[tex]\displaystyle\frac{70}{100} = \frac{7}{10} = 0.7\\\\0.7 \times 100 = 70\%[/tex]

Therefore, 70% of the students are enrolled in health class.

The expression for area of rectangle in standard form is: [tex]10x^2+3x-27[/tex]

Step-by-step explanation:

The area of rectangle is given by:

[tex]Area = Length * Width[/tex]

Here, in the question, we are given length and width of the rectangle

Length = 2x-3

Width = 5x+9

The area of the rectangle will be:

[tex]Area = (2x-3)(5x+9)\\= 2x(5x+9)-3(5x+9)\\= 10x^2+18x-15x-27\\= 10x^2+3x-27[/tex]

Hence,

The expression for area of rectangle in standard form is: [tex]10x^2+3x-27[/tex]

what I need more information to answer your question what is the question and show me the graph please

Answer:

Put an open circle over the 1 to the right of 0. The arrow should point all the way to -5 or the 5 to the left of 0.

Step-by-step explanation:

In order to solve this, we know that x is less than one. That means that we need to circle to be over the 1, since it is the only known number in this inequality.

Since the phrase "less than" means that x cannot be more than 1, we know that in order to find the value of "x", then we need an amount lower than one, therefore, we move to the left.

Answer: y = -3/4x - 0.75

Step-by-step explanation:

The slope needs to be negative so that it's perpendicular to

y = 3/4x - 1

The equation then looks like this

y = -3/4x

We can get an exact y intercept number by using the cordinates

Lets input cordinates (3,-3)

-3 = -3/4(3)

-3 = -2.25 - 75 ( I inferenced )

-3 = -3

now that we got the y intercept lets put it all together

y = -3/4x - 0.75

66*0.5=3.30

7.80-3.30=4.50

4.50/0.10=45

Answer:

Step-by-step explanation:

Given that:

Sales price on the sales receipt (including the sales tax) = $211.86

Sales tax = 7%

To find:

The cost of the bicycle without the sales tax = ?

Solution:

First of all, we will have to let the cost of bicycle without the sales tax.

Let the cost of bicycle without the sales tax = $[tex]x[/tex]

Cost of bicycle without the sales tax and with sales tax is given as equal to $211.86.

Writing the equation as per question statement:

[tex]x+x\times 7\%=\$211.86\\\Rightarrow \dfrac{107}{100}x=\$211.86\\\Rightarrow x=\dfrac{21186}{107}\\\Rightarrow \bold{x = \$198}[/tex]

Therefore, the cost of bicycle without the sales tax = $198

Answer:

The value of x is 50

Step-by-step explanation:

In the given figure

∵ Two secants intersected outside the circle

∵ The measures of the intercepted arcs are 30° and 130°

∵ x is the measure of the angle formed between them

→ By using the fact above

∴ x = [tex]\frac{1}{2}[/tex] (130 - 30)

∴ x = [tex]\frac{1}{2}[/tex] (100)

∴ x = 50

∴ The value of x is 50

Think homework is hard? Say to yourself, "Homework is easy." and trudge on through. After some time, your mindset *will* improve, and your attitudes will change from negative to positive.

Also, try to go out more often. Doing exercise, socializing, all of which will produce serotonin and will improve your outlook on life and attitude.

Answer:

Mean=685

Variance=36.7

Step-by-step explanation:

The mean of uniform discrete distribution can be expressed as the average of the boundaries

mean=( b+a)/2

The variance of uniform discrete distribution can be expressed as the difference of the boundaries decreased by 1 and squared, decreased by 1 and divided by 12.

σ²=[(b-a+1)^2 - 1]/12

We were given the wavelength from from 675 to 695 nm which means

a= 675, b= 695

We can now calculate the mean by using the expresion below

mean=( b+a)/2

Mean=( 675 + 695)/2

=685

The variance can be calculated by using the expression below

σ²=[(b-a+1)^2 - 1]/12

σ²=[(695-675+1)^2 -1]/12

σ²=440/12

σ²=36.7

Therefore, the the mean and variance, of the wavelength distribution for this radiation are 685 and 36.7 respectively

Step-by-step explanation:

The value of z-score will be –0.4. Then the correct option is B. The probability will be 0.34458. Then the correct option is C.

The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

The z-score is given as

z = (x – μ) / σ

Where μ is the mean, σ is the standard deviation, and x is the sample.

The annual salary of teachers in a certain state X has a mean of $54,000 and standard deviation of σ = $5,000.

The probability that the mean annual salary of a random sample of 64 teachers from this state is less than $52,000 will be

The mean of the sampling distribution of sample of means is $54,000 and the standard deviation is select an answer $5000.

Then the z-score will be

z = (52000 – 54000) / 5000

z = –2000 / 5000

z = –0.4

Then the correct option is B.

Then the probability will be

P(x < 52000) = P(z < 0.-4)

P(x < 52000) = 0.34458

Then the correct option is C.
