Answer:
D. y = -5/7x + 5
Step-by-step explanation:
5x + 7y = 35
-5x -5x
7y = 35 - 5x
/7 /7 /7
y = 35/7 - 5/7 x
y = 5 - 5/7x
Equation of the given line is:
y = 3x + 2
Slope of the line = m = 3
Since we are to find equation of line parallel to this line, the slope of new line will be the same as slope of parallel lines is the same.
So we are to find a line with slope 3 and passing through the point (10,1). Using the point-slope form of equation we can write:
y - 1 = 3(x - 10)
y = 3x - 30 + 1
y = 3x - 29
⇒
- 3x + y = 29
So option C gives the correct equation of the line.

Step-by-step explanation:
Work:
-2(3x+2)≥-6x-4
-6x-4≥-6x-4
-4≥-4
0≥0
Answer:
All real numbers are solutions.
Explanation:
The first step was to multiply 3x+2 by (-2). That gives you -6x-4, which is the same as the other side. You would then add 6x to both sides, giving you -4≥-4. The last step would be to add four to both sides. When you get 0≥0, you know that all real numbers are solutions.
Answer:
d=12
Step-by-step explanation:
15-d/4+2=1/2
15-d/6=1/2
2(15-d)=6
30-2d=6
30-6=2d
24=2d
d=12
