Answer:
x=32
Step-by-step explanation: x/2-7=9 find what number minus 7 equals 9 multipy that by 2 and there you go that is the answer
Answer:
Yes
Step-by-step explanation:
When the greatest common factor of two numbers is 1 or -1, the numbers are known as relatively prime. This means there are no numbers that can be factored out of both of the numbers, meaning if the numerator and denominator are relatively prime, they can not be simplified any further.
Answer:
The decimal point moves 2 places to the right.
Step-by-step explanation:
EX:
decimal: .95
percent: 95%
the decimal point moves 2 places to the right
The constant of proportionality k is given by y = kx.
In your equation, it would be r = km.
Can you now spot it?
To find the equation of a line using two given set of points, you must first find slope. To do so, we must use the slope formula:
y2 - y1 / x2 - x1
In this case:
1 - 9 / -1 - 3 = -8 / -4
- 8 / -4 = 2 (simplified)
Now we can use the point-slope formula:
y - y1 = m(x - x1)
y - 1 = 2(x + 1 )
y - 1 = 2x + 2
y = 2x + 3
In order to make 3x - y = 6 in slope intercept form, we must isolate y.
- y = -3x + 6
Note: y cannot be negative, so we'll multiply both sides by -1
( -1 ) - y = - 3x + 6 ( -1 ) = y = 3x -6
