Answer: y-4=-3(x+4) or y=-3x-8
Step-by-step explanation:
To find the equation of the line with a given point and slope, we can fill them into the point-slope formula. The point-slope formula is y-y₁=m(x-x₁).
y-4=-3(x-(-4)) [multiply]
y-4=-3(x+4)
Another equation could be slope-intercept form. It is y=mx+b.
y-4=-3(x+4) [distribute]
y-4=-3x-12 [add both sides by 4]
y=-3x-8
Now, we know that the equation is y=-3x-8 or y-4=-3(x+4).
Answer:
B. The original purchase total must be at most to $44 before the discounts are applied.
Step-by-step explanation:
Solve the inequality by adding $10, then dividing by 0.8.
0.8x -$10 ≤ $25.20
0.8x ≤ $35.20 . . . . . . . . add $10
x ≤ $35.20/0.8 . . . . . . . divide by 0.8
x ≤ $44 . . . . . . . . . the before-discount purchase must be at most $44
Answer:
13
Step-by-step explanation:
if y = 4, then 4 + 9 = 13
Answer:
Line
intersects line 
Step-by-step explanation:
We are given that
Subtract one equation from other then we get
Substitute the value of x in first equation then we get
Hence, the solution 
is the intersection point of two line equations .
Answer:Line intersects line
Answer:
3.6 pounds
Step-by-step explanation:
If 1 bottle weighs 3/5 pounds
the 6 bottles will weigh 6 x 3/5
= 18/5
ratio method :
1:3/5
6:x
since the ratios are direct we can cross multiply
18/5 = 1x
so the 6 bottles weigh 18/5 pounds or 3.6 pounds
