The first term is, x2 its coefficient is 1 .
The middle term is, -3x its coefficient is -3 .
The last term, "the constant", is -40
Step-1 : Multiply the coefficient of the first term by the constant 1 • -40 = -40
Step-2 : Find two factors of -40 whose sum equals the coefficient of the middle term, which is -3 .
-40 + 1 = -39
-20 + 2 = -18
-10 + 4 = -6
-8 + 5 = -3 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -8 and 5
x2 - 8x + 5x - 40
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-8)
Add up the last 2 terms, pulling out common factors :
5 • (x-8)
Step-5 : Add up the four terms of step 4 :
(x+5) • (x-8)
Which is the desired factorization
Answer: 6 • ( x + 5 ) • ( x - 8 )
Answer:
the answer is from the given replacement is 4
Answer:
the coordinates of equations
1.4x+y=-7
for x =0
f(0,y)=4(0)+y=-7
y=-7
for y=0
f(x,0)=4x+0=-7
4x=-7
x=-7/4
2.x-y=2
for x=0
f(0,y)=0-y=2
-y=2
y=-2
for y=0
f(x,0)=x-0=2
x=2
graph all of the equations coordinates or you can look the image
so the answers are : {-3,-1}

Answer:
Step-by-step explanation:
first your going to do the least common multiple which is 12 for both then your going to subtract because were trying to find out how many students did there work correctly. so, whatever you do to the denominator you do to the numerator so, its going to be 10/12 - 9/12= 1/12 is your answer.
