-9y + 8 = -91-9y = -91 -8-9y = -99y = -99-----9y = 11-99/-9 = 11 because -9X11 = -99
To answer the question you need to know what Y=.
y = 16/33
The interval is, presumably, the range = 12.
4
-8 - 5y = 12 - 9y -8 + 4y = 12 4y = 20 y = 20/4 or 5
-9y + 8 = -91-9y = -91 -8-9y = -99y = -99-----9y = 11-99/-9 = 11 because -9X11 = -99
Without an equality sign it is not a straight line equation but if you mean 9y-12x-72 = 0 then y = 4/3x+8
-8-5y = 12-9y 9y-5y - 12+8 4y = 20 y = 5
9y + 10 = - 8 subtract 10 from both sides 9y = -18 Divide by 9 on both sides y = -2
If you mean: 9y = 72 then y = 72/9 = 8
The solution to the system of equations x-9y=65 and 6y-8x=8 is (-7,-8).The easiest way to do substitution is to find the variable that can be isolated the easiest, that is, get either x or y alone. The easiest variable to get alone is the x in the first equation. All you need to do is add 9y to each side. Working through the substitution:The system of equations:x-9y=656y-8x=8Step 1: Get a variable alonex-9y=65x-9y+9y=65+9yx=9y+65Step 2: Substitute into the other equation6y-8x=86y-8(9y+65)=8 → Expand6y-72y-520=8 → Combine like terms-66y-520=8 → Add 520 to both sides-66y=8+520 → Simplify-66y=528 → Divide by -66 to find yy=-8Step 3: Substitute y=-8 into the first equationx=9y+65x=9(-8)+65x=-72+65x=-7The solution to the system of equations x-9y=65 and 6y-8x=8 is (-7,-8).
-9
The use of the word 'or' means that the smallest positive integer is 6, as 6 ÷ 4 leaves a remainder of 2. If you mean the smallest positive integer what when divided by both 4 and 9 leaves a remainder of 2 then the answer is 38. 4x + 2 = M : 4x = M - 2 9y + 2 = M : 9y = M - 2 4x = 9y : x = 9y/4: x = 2.25y This means that for x to be an integer, y must = 4 or a multiple of 4. Thus, if y = 4 then 9y + 2 = 36 + 2 = 38 And, x = 9 If higher value integers were required then put y = 8,( or higher multiples of 4) Then 9y + 2 = 72 + 2 = 74 And, x = 18
if it is 3x + 9y, then 3(x+3y) or if it is a product...then it doesn't make sense, since then 3x9y=27xy
To answer the question you need to know what Y=.
The question asks for a function of 'y', so we'll show 'x' as a function of 'y':Given: 8x - 9y = 2Add 9y to each side:8x = 2 + 9yDivide each side by 8:x = 2/8 + 9y/8orx = 1/8 (2 + 9y).==================================================If the questioner actually wants to see it in the more familiar form of [ y = a function of x ],we can massage the original equation around to show that as well.Given: 8x - 9y = 2Subtract 8x from each side:-9y = 2 - 8xMultiply each side by -1:9y = 8x - 2Divide each side by 9:y = 8x/9 - 2/9ory = 1/9 (8x - 2)
