Break the expression into two groups, then if you factor out what you need to do, then factor out the common term, you'll end up with ( 3x - 11 ) ( x - 10 )
let those numbers be x and y
According to your question
x + y = -7
x - y =14
adding both equations
2x = 7
or x = 7/2
substitute value of x in either equation
y = -21/2
So,
x= 7/2
y=-21/2
Hope this helps!
Thanks
x = -2
y = 1
let's multiply second equation by 4 to get a common coefficient of y variable.
16x-8y=-40
add the equations
3×+8y=2
16x-8y=-40
----------------
3x+16x = -38
19x = -38
x = -2
substitute x
3×-2 + 8y = 2
-6 + 8y = 2
8y = 2+6
y = 1
check the answer
-6+8 = 2
-8-2= -20
D = {5; 7; 9; 11}
y = 45 - 3x
substitute the values of x from the domain to the equation:
for x = 5: y = 45 - 3 · 5 = 45 - 15 = 30for x = 7: y = 45 - 3 · 7 = 45 - 21 = 24for x = 9: y = 45 - 3 · 9 = 45 - 27 = 18for x = 11: y = 45 - 3 · 11 = 45 - 33 = 12
Answer: The range is { 12; 18; 24; 30}.
Answer: Well, there is two ways for addition and two ways for division. either Add 67 5 times (67 + 67 + 67 + 67+ 67) to get 335 or add 5 67 times (5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 etc.) to get 335, And for division (my favorite part) Either get 335 and see if 67 can be multiplied to get 3, 33, or 335. and if either 3, 33, or 335 is to big subtract what you get when you multiply (Enter Number) with 67 to get anything remotely close to 3, 33, or 335. (NOT MORE THAN 3, 33, OR 335 ONLY EXACT OR LESS THAN) or do the exact same with 5.
