Answer:
The pair of lines in (c) are parallel; so are the pair in (d).
Step-by-step explanation:
Rule: Two lines are parallel if their slopes are equal. If the slopes of two different lines are equal, then the lines are parallel.
Let's look at these four possible answer choices with that in mind:
a) the slopes are not equal; they are negative reciprocals. These lines are not parallel.
b) The slopes are not equal; one is positive and one is negative. These lines are not parallel.
c) Both of these lines have the slope 4; that is, their slopes are equal. Therefore these two lines are parallel.
d) y = 9 and y = 18 are both horizontal lines, and are therefore parallel. 9 and 18 do not represent slopes; rather, they represent y-intercepts.
Answer:
6
Step-by-step explanation:
Step 1: Multiplying the power
2 x 2 x 2 = 8
Step 2: Subtracting:
15-8 = 7
Step 3: Dividing
42/7 = 6
Answer : 6

Answer:
(x, y) = (1, -9)
Step-by-step explanation:
y = -9x
-8x-6y = 46
By substituting the value of y (first equation) into the second equation, we get,
-8x - 6*(-9x) = 46
-8x + 54x = 46
46x = 46
x = 1.
So, y = -9
Yes the answer would be 22.5
Answer:
- C. Each jar has 12/7 cups of blueberries.
Step-by-step explanation:
- 12 cups of blueberries ⇒ 7 jars of jam ⇒
- 12 / 7 cups of blueberries ⇒ 7 / 7 jars of jam ⇒
- 12 / 7 cups of blueberries ⇒ 1 jar of jam
<u>The answer options (restored as original):</u>
- A. Each jar has 7/12 cup of blueberries. ⇒ <u>incorrect</u>
- B. Each jar has 1/12 of 7 cups of blueberries. ⇒ <u>incorrect</u>
- C. Each jar has 12/7 cups of blueberries. ⇒ correct
- D. Each jar has 1 5/12 cups of blueberries. ⇒ <u>incorrect
