What is the difference between 10 x 4 + 5 and 10 x (4 + 5).

Answers

Answer 1

Answer:

The difference is that in the first equations you multiply the 10 by 4 first because of PEMDAS rule. But in the second equation you add the 4 and 5 before multiplying. Thats the only difference :D

Step-by-step explanation:

I hope this helps!!!!

Answer 2

Answer:

[tex]10*4+5\\By\ applying\ BODMAS, as\ there\ are\ no\ brackets\ we\ directly\ multiply(M)\ 10\\ with\ 4\ and\ add(A)\ the\ product\ with\ 5.\\[/tex]

[tex]Hence,\\10*4+5\\=40+5\\=45[/tex]

[tex]10*(4+5)\\By\ applying\ BODMAS,\ due\ to\ the\ presence\ of\ the\ brackets\ we\ carry\\the\ operations\ inside\ the\ bracket.\\ Hence,\\10*(4+5)\\=10*9\\=90[/tex]

[tex]See\ the\ difference!![/tex]

(-10,-7) and (-5,-9)

Answers

Answer:

for the first one, go left 10, then down 7, and you have your point. for the second one, go left 5, then down 9, and you have your point.

for the y-axis, negative means down

Is the point (10,-2) a solution to the equation y = -2x + 16? Explain,
??? pls answer

Answers

Answer:

no

Step-by-step explanation:

y = -2x + 16

-2 = -2(10) + 16

-2 = -20 + 16

-2 = -4

which is wrong

Plug the point (10,-2) into y = -2x + 16 and solve. If the equation is a true, then yes, it is a point on the equation.

y = -2x + 16 > -2 = -2(10) + 16

Now, solve.

-2 = -2(10) + 16 > -2 = -20 + 16  - Start by multiplying out parenthesis.

-2 = -20 + 16 > -2 = -4 - Add.

-2 = -4

The equation cannot be simplified any further. Since -2 is not equal to -4, we can conclude that no, (10,-2) is not a solution to the equation y = -2x + 16.

Answer:

f(-7) = -6

f(10) = 9

Step-by-step explanation:

Because -7 is less than 0 you can use the top equation -7 + 1 to get 6

Because 10 is greater than 0 you can use the bottom equation 10 - 1 to get 9
