Note: I am assuming your second equation is:

x = 2y - 1

Answer:

The solution to the system of equations is:

Step-by-step explanation:

Given the system of equations

2x+y=3

x = 2y - 1

solving the system of equations using the elimination method

[tex]\begin{bmatrix}2x+y=3\\ x=2y-1\end{bmatrix}[/tex]

Arrange equation variables for elimination

[tex]\begin{bmatrix}2x+y=3\\ x-2y=-1\end{bmatrix}[/tex]

Multiply x-2y=-1 by2:     2x-4y=-2

[tex]\begin{bmatrix}2x+y=3\\ 2x-4y=-2\end{bmatrix}[/tex]

subtracting the equations

[tex]2x-4y=-2[/tex]

[tex]-[/tex]

[tex]\underline{2x+y=3}[/tex]

[tex]-5y=-5[/tex]

now solve -5y = -5 for y

[tex]-5y=-5[/tex]

Divide both sides by -5

[tex]\frac{-5y}{-5}=\frac{-5}{-5}[/tex]

Simplify

[tex]y=1[/tex]

For 2x+y=3 plug in y=1

[tex]2x+1=3[/tex]

subtract 1 from both sides

[tex]2x+1-1=3-1[/tex]

Simplify

[tex]2x=2[/tex]

Divide both sides by 2

[tex]\frac{2x}{2}=\frac{2}{2}[/tex]

Simplify

[tex]x=1[/tex]

Therefore, the solution to the system of equations is:

Answer: 0.6472

Step-by-step explanation:

Given: The proportion of unvaccinated school-age children = 13.5%

Then, the  proportion of vaccinated school-age children :p=100%-13.5%

= 86.5% = 0.865

Total children selected :n=3

Binomial probability formula:

[tex]P(X=x)=\ ^nC_xp^x(1-p)^{n-x}[/tex]

The probability that all three children have been vaccinated :

[tex]P(X=3)=\ ^3C_3(0.865)^3(0.135)^0\\=(1)(0.647214625)\approx0.6472[/tex]

Hence, the required probability = 0.6472

Actually Welcome to the Concept of the Linear equations.

Let the number of bicycles = x

and number of tricycles = y

the relationship given is,

x = 5y-1

number of wheels of bicycle = 2x and of tricycles=3y

and other relation is, 2x+3y = 154

so now substituting we get as,

==> 2(5y-1) +3y= 154

10y-2+3y = 154

13y = 154+2

=> y = 12

=> 12*3 = 36 wheels of tricycles

so, 154-36 => 118 wheels of the bicycle.

so the number of bicycles = 118/2 = 59

hence,

==> number of bicycles = 59 and tricycles = 12

Step-by-step explanation:

give them brain, they're correct.

The Unit Rate for Amy will be 22 pages per hour.

The Unit Rate is defined as means a rate for one of something.

We have,

Amy can read 88 pages in 4 hours.

So,

Now,

Number of pages Amy can read in 1 hour [tex]=\frac{88}{4}[/tex]

So,

Number of pages Amy can read in 1 hour = 22,

That means,

The  Unit Rate for Amy is 22 pages per hour.

Hence, we can say that the Unit Rate for Amy will be 22 pages per hour.

Step-by-step explanation:

1.)20x + 100 = 1440

-Let the number of couples be x. So, the total amount paid by all the couple’s are $20x. School paid $100 as security, so the total amount paid is

Answer:

10 ft by 12 ft

Step-by-step explanation:

This problem requires you to first write an equation to represent the situation. Here we will represent the shorter side of the doghouse with the variable x, the longer side will be represented with x+2 because it is 2 feet longer.

48 = x * (x+2)

This represents the area of the doghouse as the product of the width and length of the doghouse.

48 = x^2 + 2x

Now, we need to move all the items onto one side of the equals sign, it is best to have the x^2 be positive.

0 = x^2 + 2x - 48

Now, we factor to find what x equals.

0 = (x-6) * (x+8)

From here, we can use each of the terms in parentheses to solve for x.

0 = x-6

x = 6

0 = x+8

0 = -8

Here we know that the shorter side has to be 6 ft because length is a positive number, and we can determine that the longer side is 8 ft because it is 2 ft longer. The dimensions of the slab are therefore 10 ft by 12 ft because the slab is 2 ft on each side, therefore adding an extra 4ft to the dimensions because the 2ft is added on each side.

Answer:

D

Step-by-step explanation:

No the function is not an exponential function as the domain values are not at regular intervals although the range values have a common factor.

The exponential function is a function which is formed by the unit e which is equal to 2.718.

The differences between x-values are  -1, -1, -1, -2 . . . . not a constant difference

The ratios of y-values are 2/8 = 0.5/2 = 0.125/0.5 = 0.25 . . . . a constant difference

The domain values do not have a common difference shows the common factor of the range values which are of no use. So, the function is not exponential.

Hence the table does not show exponential function in any way because the domain values are at regular intervals and the range values have a common factor 0.25.

Now all we have left are c, f and *i,

*(because if converted to y intercept the sign will flip because the y is negative in this equation.)

Now convert to y intercept form (y=mx+b).

Flip the sign because some are negative.

C. y>(-5/2)x+0

I. y>(4/3)x-(5/3)

Now use rise over run, or you could just look at the b. B is equal to the y-intercept. It can't be 0 or 9, and (-5/3) is equal to -1.67. So isn't that the closest to what the y intercept looks like in the graph?

a)               Parallel forms reliability

b)               Interrater reliability

c)               Internal consistency reliability

Step-by-step explanation:

Types of Reliability Tests:  

Test-retest reliability = measures the results consistency with the application of the same test at different times.

Interrater reliability = shows consistent ratings by different examiners.

Parallel forms reliability = uses alternative versions of an equivalent test to probe for similar results.

Internal consistency reliability = this test checks the consistency of individual items of a test.
