Yes because whether you flip two negative integers around, the answer would still remain the same since its addition.

For example:
-9+-3 = -12 = -3+-9

Please help i don’t understand

Answer:

Step-by-step explanation:

First of, let's make a table for y = cos(x)

(x , y): (0 , 1) (π/2 , 0) (π , -1) (3π/2 , 0) (2π , 1)

Now, making a table for y = 2cos(x) is simple. We just have to multiply all the y-values from the previous table by 2.

(x , y): (0 , 2) (π/2 , 0) (π , -2) (3π/2 , 0) (2π , 2)

Graphing these coordinates, we find that the answer is D.

M-N is $M-N=2x^2+11x-9$

Option B is correct.

Step-by-step explanation:

If $M=5x^2+7x-4$ and $N=3x^2-4x+5$ then find M-N

We need to subtract N from M

We will combine like terms (terms having same variable and exponent) and then solve them:

$M=5x^2+7x-4$

$N=3x^2-4x+5$

$M-N=5x^2+7x-4-(3x^2-4x+5)\\M-N=5x^2+7x-4-3x^2+4x-5\\Combining\,\,like\,\,terms:\\M-N=5x^2-3x^2+7x+4x-4-5\\M-N=2x^2+11x-9$

So, M-N is $M-N=2x^2+11x-9$

Option B is correct.

22-3 (x-70) = x+20 <br><br>please help

Elena L [17]

Answer:

x = 53

Step-by-step explanation:

22 - 3 ( x - 70 ) = x + 20 Multiply out

22 - 3x + 210 = x + 20

22 + 210 - 3x = x + 20

232 - 3x = x + 20

232 - 3x + 3x = x + 3x + 20

232 = 4x + 20

232 - 20 = 4x + 20 - 20

212 = 4x

212/4 = 4x/4

212/4 = x

x = 53
