<span>the line through points (-1,-2) and (5,3)
slope=(3-(-2))/(5-(-1))=5/6
for a perpendicular line slope =-6/5=-1.2
y=(-6/5)x+b
7=(-6/5)*3+b
7=-18/5+b
7=-36/10+b
7=-3.6+b
b=10.6
y=-1.2x+10.6</span>

Answer:

The equation of the line would by y = -6/5x + 53/5

Step-by-step explanation:

In order to find this, we must first find the slope of the original line. We can do this with the slope formula.

m (slope) = (y2 - y1)/(x2 - x1)

m = (3 - -2)/(5 - -1)

m = (3 + 2)/(5 + 1)

m = 5/6

Now that we have the slope of this line, we can find the slope to the other line by using the reciprocal and opposite of it. So we flip 5/6 to get 6/5 and then we make it negative to get -6/5. Now that we have this, we can use the slope and a point in point-slope form to find the line.

y - y1 = m(x - x1)

y - 7 = -6/5(x - 3)

y - 7 = -6/5x + 18/5

y = -6/5x + 53/5

in a salad with vegetables containing 50 calories dressing is added at 100 calories per ounce. The total number of calories can
Vika [28.1K]

Answer:

Step-by-step explanation:

To get the reasonable range of the situation, we will find the minimum value and maximum value of the calories that can be dressed.

The minimum occur at when x = 0

f(0) = 100(0) +50.

f(0) = 50

Hence the minimum value of the calorie is 50.

The maximum value occur at f'(x)

f'(x)  = 100

Hence the maximum value of the calorie is 100

Hence, the reasonable range for the situation is 50 ≤ x ≤ 100

Determine the sum: (14abc2 + 12a2b + 16b2c) + (−3abc2 + 2b2c).
Alenkinab [10]
The answer is 11abc^2 + 12a^2b + 18b^2c because:
14abc^2-3abc^2 is 11abc^2
12a^2b + 0 = 12a^2b
16b^2c +2b^2c = 18b^c
