Let
<u>Find the sum of the mixed numbers x and y</u>
therefore
<u>the answer is</u>
Yes, the sum of two mixed numbers be equal to 
, only if you include a negative mixed number
Answer:
3x+5y+12=0
Step-by-step explanation:
This information is given in the question:
m=-3/5
x1=-4
y1=0
The formula for the equation of a line is:
y-y1=m (x-x1)
From this we can make a substitution
y-0=-3/5 (x--4)
Next simplify
y=-3/5 (x+4)
Multiply both sides of the equation by 5
5y=-3x-12
Make the right side of the equation equal to zero
3x+5y+12=0
This is the equation of the line in general form.
Answer:
15
Step-by-step explanation:
the question has a slope of 1/3x with a y intercept of 2,
Thus, once the line reaches 9 in its y value, the x value would be 15
Answer:
true for all x
Step-by-step explanation:
3x - 4 ≤ 2
Add 4 to each side
3x - 4+4 ≤ 2+4
3x<6
Divide by 3
3x/3 <6/3
x<2
or
2x + 11 ≥ -1
Subtract 11 from each side
2x + 11-11 ≥ -1-11
2x≥ -12
Divide by 2
2x/2 ≥ -12/2
x ≥ -6
x<2 or x ≥ -6
true for all x
74 + 5x + (3x + 2) = 180 ** The sum of the 3 angles in a triangle is 180**
74 +5x + 3x + 2 = 180
76 + 8x = 180
8x = 180 - 76
8x = 104
X = 13
