Answer 1

Answer: $(18, y) \ and \ (20, -15) \ is \ (19, -5) \n \n(x _(m),y _(m)) =[ (x_(1) +x _(2))/(2) , (y _(1)+y _(2))/(2)] \n \n (19,-5)= [(20+19)/(2),(y-15)/(2)] \n \n(19,- 5)= [19,(y-15)/(2)] \n \n -5= (y-15)/(2) \ \ / *2\n \n-10 = y-15\ \ | +15\n \ny=-10 + 15 \n \n y = 5\n \n(19,- 5)= [19,(5-15)/(2)] \n \n(19,- 5)= ( 19,-5) \n \n \n Aswer : y = 5$

4 6/7 + 3 5/7=____

Answers

First add the fractions.

6/7 + 5/7 = 1 4/7

Then add the whole numbers

4 + 3 = 7

Then add the mixed number to the whole number

7 + 1 4/7 = 8 4/7

Your answer is 8 4/7

What is the equation of the line that passes through the point (5,-1)(5,−1) and has a slope of \frac{1}{5} 5 1

Answers

Answer:

This is easy how do I send my work like a photo

Step-by-step explanation:

Final answer:

The equation of the line is y = 1/5x - 2.

Explanation:

The equation of a line can be written as y = mx + b, where m is the slope of the line and b is the y-intercept.

Given that the line passes through the point (5,-1) and has a slope of 1/5, we can substitute these values into the equation to find b.

Using the point-slope formula, we have y - y1 = m(x - x1).

Plugging in the values for (x1, y1) as (5, -1) and m as 1/5, we can simplify the equation to y + 1 = 1/5(x - 5).

Rearranging the equation gives us y = 1/5x - 10/5, which can be simplified to y = 1/5x - 2.

Therefore, the equation of the line that passes through the point (5,-1) and has a slope of 1/5 is y = 1/5x - 2.

Solve 4^2x=7 by graphing

Answers

Answer:

0.702 is the solution of this function.

Step-by-step explanation:

We have

$4^(2x)=7\n\n4^(2x)-7=0$

Let us plot $y=4^(2x)-7$ when y value of this function is zero then that is the solution of $4^(2x)=7$

Refer the figure given, we have at x = 0.702 y value is zero that is 0.702 is the solution of this function.

I can't solve that by graphing but I'll try logarithms:
log(7)4 = 2x
log(7)/log(4) = 2x
1.403 = 2x
x = 0.702

Jane arranges m chairs in each of n rows to seat x people.The formula to find the number of chairs in each row is m =
_____________________
If 60 people attend the meeting and each row has 4 chairs, there are _______________________________________
rows.

Answers

The formula to find the number of chairs in each row is m = x ÷ n,
where
m - the number of chairs,
n - the number of rows,
x - the number of people.

If 60 people attend the meeting and each row has 4 chairs, there are 15 rows.
This is assumed using the above formula:
m = x ÷ n

If:
x = 60
m = 4

Then:
4 = 60 ÷ n
⇒ n = 60 ÷ 4
⇒ n = 15

Which of the sets shown includes the elements of set Z that are both odd numbers and multiples of 7?Z={-21, -14, -7.0, 7, 14, 21}
A {-21, 21)
B. {-21.-7. 7. 21)
C: {-14, 0.14)
D. {-21, -14, -7)

Answers

Answer:

B. {-21.-7. 7. 21)

Step-by-step explanation:

The set made up of odd numbers and multiples of 7 is given as;

{-21.-7. 7. 21)

Multiples of 7 are usually those numbers where 7 is factor.

Odd numbers are numbers that cannot be divide by 2.

So, the most fitting answer is B.

For every 24 minutes of television,there are 6 minutes of commercials.how many minutes of commercials are there in 1 hour and 36 minutes of television

Answers

96 minutes total divided by 24 which is 4 then 4 times 6 is 24 so 24 min of commercials are in 1 hour and 36 min

Answer:

24 minutes.

Step-by-step explanation:

I hour of television plus 36 minutes equals 96 minutes of T.V. (way too much if you ask me XD). Divide the 96 by the previous 24, resulting in 4. 4x6= 24 again, so therefore there are 24 minutes of commercials in I hour, 36 minutes of television.
