Answer:
hello : coordinate pair is: (5 ; 1)
Step-by-step explanation:
you have this system :
5x - 3y=22 ......(1)
-4x + y= -19.....(2)
by (2) : y = 4x -19
put y in (1) : 5x - 3 (4x -19) =22
5x -12x +57 = 22
- 7x = -35
x = 5
but : y = 4x -19 so : y = 4(5) -19 = 1
coordinate pair is: (5 ; 1)
Answer:
92
Step-by-step explanation:
The two angles add to make a straight line, so their sum is 180
88+x = 180
Subtract 88 from each side
88+x-88 = 180-88
x =92
Answer:
(y + 1) • (y - 4)
Step-by-step explanation:
Trying to factor by splitting the middle term
1.1 Factoring y2-3y-4
The first term is, y2 its coefficient is 1 .
The middle term is, -3y its coefficient is -3 .
The last term, "the constant", is -4
Step-1 : Multiply the coefficient of the first term by the constant 1 • -4 = -4
Step-2 : Find two factors of -4 whose sum equals the coefficient of the middle term, which is -3 .
-4 + 1 = -3 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -4 and 1
y2 - 4y + 1y - 4
Step-4 : Add up the first 2 terms, pulling out like factors :
y • (y-4)
Add up the last 2 terms, pulling out common factors :
1 • (y-4)
Step-5 : Add up the four terms of step 4 :
(y+1) • (y-4)
Which is the desired factorization
Final result :
(y + 1) • (y - 4)
9.1 would be a rational number or 9.7 or 9.04 or any number between 9 and 10 that can also be written as a fraction.
√82 or √96 would be an irrational number that is between 9 and 10 or any square root larger than 81 since the √81 is 9 and below √100 since the √100= 10.
