Answer:
Step-by-step explanation:
The sign of a product or quotient cannot be determined by the positive number (t), so we can ignore it. The sign of the expression will be negative if and only if there are an odd number of negative factors.
Here, there are 67 (an odd number) negative factors, so the expression will be negative.
Answer:
4. A
5. B
Step-by-step explanation:
4. I'll solve question four first:
The two marked points on the line are (-2, -3)&(2, 5). Using the formula to find slope(y2-y1/x2-x1), substitute in the points.
5--3/2--2 or 8/4;simplified to 2/1 or 2.
Now use point-slope form: y-y1 = m(x-x1)
y--3 = 2(x--2): Substitute in the values of y1, m, and x1.
y+3 = 2x + 4: Distribute.
y = 2x + 1: Subtract three from both sides.
5. Do the same for question 5.
The first point is (-4, 2), the second point is (4, -1).
-1-2/4--4; -3/8.
Now use point-slope form:
y-2 = -3/8x -12/8: Substitute in the values of x1, y1, m, and distribute the slope to the parentheses.
y = -3/8x + 1/2
Brandon had four servings of meat and milk to complete his diet. After adding up all of the fruit/veggie and bread/cereal, we are left with 720 calories. Divide this by 180, the number of calories in one serving of milk and meat, and you get four.
Answer:
n = 1
Step-by-step explanation:
4/5 - 3/5 = 1/5n
collect like terms
-3/5 = 1/5n - 3/5n
-3/5 = 1 - 4/ 5n
-3/5 = -3/ 5n
cross multiply
-15n = -15
Divide both sides by -15
n = 1
