Answer: 0.7

Step-by-step explanation:

16.4 - 15= 1.4

1.4 ÷ 2= 0.7

Hope this helps :)

Answer:

The answer is

[tex] \huge y = 2x + 15[/tex]

Step-by-step explanation:

To find an equation of a line when given the slope and a point we use the formula

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

From the question we have

[tex]y - 3 = 2(x + 6) \\ y - 3 = 2x + 12 \\ y = 2x + 12 + 3[/tex]

We have the final answer as

[tex]y = 2x + 15[/tex]

Hope this helps you

Answer:

No

Step-by-step explanation:

a function can not repeat

The table given in the problem does not represent a function.

A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.

The ordered pair for data given in the table is as below,

{(2, 5), (3, 6), (4, 6), (5, 9), (8, 11)}

Suppose x denotes the first elements and y the second elements of the  ordered pair.

Then, from the ordered pair it is concluded that for x = 3 and x = 4, the value of y is 6.

Which implies that the values of x are not unique for a given value of y.

Thus, it does not represent a function.

Hence, the given table does not represent a function as the values in the domain set are not unique.

Answer:

There are 9 dimes and 18 nickels.

Step-by-step explanation:

Let d = be the number of dimes

     n = be the number of nickels

    d + n = 27...eq.1

   0.10d + 0.05n = 1.80...eq.2

Solve the system of equations

   d + n = 27

10d + 5n = 180  ( multiply eq.2 by 100 )

 -5d - 5n = -135

      5d = 45

        d = 9 , there are 9 dimes so,0.90

        n = 27 - 9 = 18,   there are 18 nickels so, 0.90

To check:   9 dimes + 18 nickels = 27 coins

                0.90 + 0.90 = $ 1.80 total value of the coins

Answer:

x and y intercepts are alike because they're both on the graph ,they help you graph a line, they can be both found in the slope-intercept form equation

they're different one is when it can be found where it crosses the X line and one can be found where it's the y line, when is found at the end of the equation for slope intercept form and what is found near the slope. x-intercept is an input and y-intercept is an output

Answer:

10 (2 and 10 can both divide into it)

Answer:

[tex]\frac{16}{x} = \frac{80}{100}[/tex]  

Step-by-step explanation:

To set up this proportion, we know that 16 must correspond with 80% and the x, the number we're looking for must correspond with 100%

[tex]\frac{16}{x} = \frac{80}{100}[/tex]

This would be the correct proportion, and you could simplify it to equal

[tex]\frac{16*100}{80}[/tex]

Answer:

y = 7x - 47

Step-by-step explanation:

y = mx + b (m is slope, b y-intercept)

Parallel lines have the same slope.

y - [tex]y_{1}[/tex] = m( x - [tex]x_{1}[/tex] )

~~~~~~~~~~~~~~~~

y = 7x + 1

m = 7

(6, - 5)

y + 5 = 7 (x - 6)

y = 7x - 47

Answer:

4/12

Answer:

x-8 is a factor of f(x)

Step-by-step explanation:

The polynomial remainder theorem states that the remainder of the division of a polynomial f(x) by (x-a) is equal to f(a).

We are given the function

[tex]f(x)=-2x^3+17x^2-64[/tex]

And it's required to find if x-8 is a factor of f.

Applying the mentioned theorem, we only have to find f(8):

[tex]f(8)=-2\cdot 8^3+17\cdot 8^2-64[/tex]

Operating:

[tex]f(8)=-2\cdot 512+17\cdot 64-64[/tex]

[tex]f(8)=-1024+1088-64[/tex]

[tex]f(8)=0[/tex]

Thus, x-8 is a factor of f(x)

Answer: It’s A

Step-by-step explanation: C= -14/3 which is simplified to -4 2/3

Answer:

A.

Step-by-step explanation:

So you foil 2c and -5

Which will give you 5c+4=2c-10

Subtract 2c 5c-2c+4=2c-2c-10

Then You will get3c+4=−10

Step 3: Subtract 4 from both sides.

3c+4−4=−10−4

3c=−14

Step 4: Divide both sides by 3.

3c/3=-14/3

So it will be -14/3 which is -42/3

Which is A.

Step-by-step explanation:

if x is the amount of weekend hours, let y be the amount of weekday hours. then you can solve for x by using the equations x + y = 190 and 49x + 25y = 5275. once you have values for x and y, the other answers should be easy

The sequence 2,5,8,..... The sum of the 1st 36 terms in arithmetic sequence is 1962.

Given that,

The sequence 2,5,8,.....

We have to find the sum of the 1st 36 terms of the sequence.

We have an sum of the sequence formula from arithmetic sequence.

The sum of all the digits in an arithmetic sequence is determined using the sum of the arithmetic sequence formula. Remember that the addition of the members is the definition of a finite arithmetic sequence. The typical order of the arithmetic sequence is (a, a + d, a + 2d,...), with "a" standing for the first term and "d" for the common difference.

Sum of the arithmetic sequence is S = n/2 {2a + (n − 1) d}

Where

S is the total of the mathematical sequence,

a is the first term,

d is difference of the terms,

n is number of terms in the sequence.

So, now a =2, n=36,d=5-2=3

S=36/2{ 2×2+(36-1)×3}

S=18{4+(35)×3}

S=18(4+105)
S=18×109

S=1962

Therefore, the sum of the 1st 36 terms in arithmetic sequence is 1962.

Answer:

alpha=0.01

Step-by-step explanation:

confidence level = 1 - alpha

so alpha = 1 - confidence level = 1 - 0.99 = 0.01

In statistics, alpha represents the value that checks the test statistic in order to determine if it is significant or not. In other words, alpha is the acceptable margin of type 1 error. Alpha is also called the significance level, which opposes the confidence level. Significance level + confidence level = 1.
