8×4= (?×7)-(?×3)

Can u sove the equation^

Answers

Answer 1
Answer: 8*4 = 32

Now, we need to solve this:-

32 = (?*7) - (?*3)
32=8*7 - 8*3
32= 56 - 24
32 = 32

So our equation is:-

8*4 = (8*7) - (8*3)
Answer 2
Answer: so solve for ?
we use commutative which is a(bc)=(ab)c or also =abc
remember that (? times 7)=1(? times7)=1 times ? times 7=? times 7=7?
and
-(? times 3)=-1(? times 3)=-1 times ? times 3=  -? times 3=-?3=-3?
so we have
8 times 4=7?-3?
7? means 7 times ? so therefor 7?-3?=7 times of ?  -3  times of ?=7-3=4 times of ? so 4?
8 times 4=4?
multiply divide both sides by 4
8=?

y = 1 over 3. x − 1
y = 3x − 1
y = −x + 1 over 3.
y = 3x + 1

Answers

it's y-intercept (0,-1) and (1,2)
so
slope = (2+1)/(1-0) = 3

equation should be y = 3x − 1

answer: y = 3x − 1

Answer:

y = 3x − 1

Simplify the expression x^2+x-2/8x^2+4x/3x^2+10x+8

Answers

Answer:

Step-by-step explanation:

x² + x  - 2 = x² - x +2x -2 = x(x - 1) + 2*(x-1)  = (x-1)(x+2)

8x² + 4x = 4x ( 2x + 1)

3x² + 10x + 8 = 3x² + 6x + 4x + 4*2  =3x  * (x + 2) + 4 * ( x + 2) = (x + 2)(3x + 4)
