Answer:

The numbers are 17 and 12.

Step-by-step explanation:

Given : The sum of two numbers is 29 and their difference is 5.

To find : What are the two numbers?

Solution :

Let the number be x and y.

The sum of two numbers is 29.

i.e. $x+y=29$ .....(1)

The difference of two numbers is 5.

i.e. $x-y=5$ ....(2)

Solving equation (1) and (2) by adding them,

$x+y+x-y=29+5$

$2x=34$

$x=17$

Substitute in equation (1),

$x+y=29$

$17+y=29$

$y=29-17$

$y=12$

Therefore, The numbers are 17 and 12.

Well first subtract 29 - 5 = 24
Therefore, 24 + 5 = 29
And 29 - 24 = 5

16. x + 8

Studentka2010 [4]

Step-by-step explanation:

Taking value of x= 4

16. 4 + 8 = 12

17. 24 ÷ 4 = 6

18. 3(4+4) = 3 × 8 = 24

19. 5 × 4 = 20

20. 30 - (5 × 4) = 30 - 20 = 10

21.( 2 × 4 )+ 5 = 8 + 5 = 13

22. 4 + 1 = 5

23. 25 × 4 = 100

24. 60 × 4 = 240

25. (25×4) + 10 = 100 + 10 = 110

I really need help >_< please and thank you

So for each of the graphs, you basically just have to fill out slope form, which is y=my+b. And to make this equation, you need to find each variable.

First, find the slope. To calculate slope, count the rise (how many units up or down) the line goes from any point to the next immediate point, then the run (how many units left or right.) This should leave you with a fraction, rise/run. For example, on number 3, from labeled points (-5, -4) to (5,2) (double check cause it’s hard to see on my phone, but i think those are the points on 1??) it rises 6 units (-4 to 2) and runs 10 units (-5 to 5). This gives you your rise/run fraction, which is 6/10, simplified to 3/5.

So the slope fills out the m part of the equation. For 3, we found that slope is 3/5, and that fits into the m variable of the slope equation.

This makes it y=3/5x+b.

The last (and considerably less confusing) step is to find b. b is the y-intercept, which is just the point in the graph where the line crosses the y-axis and x=0. On 3, this would be (0,-1) or just -1.

So fill -1 into the b slot of the equation, and you get y=3/5x-1. And thats it!!

Let me know if you still need help on any of the other problems, but I hoped this helped to clear it up!! :)

5. Part A: Show another way to find the slope of the line that passes through the points listed in the table. Your way must be d

Digiron [165]

Answer:

The slope-intercept form

y = mx + b

Here m is the slope and b is y-intercept

When b= 0

y = mx

and

m = y/x

In this case Avery's method works

When b≠0

m = (y -b)/x

In this case Avery's method brings wrong outcome

Answer:

-80x + 24 (A)

Step-by-step explanation:

To solve this, we need to break the brackets. This is done by multiplying -8 to 10x and -3 to give us our final answer of -80x + 24.

So, the answer is A.
