What is the slope of a line perpendicular to the line whose equation is x−2y=12.

Mathematics
1 answer:
seraphim [82]2 years ago
6 0

Answer:

-2/x

Step-by-step explanation:

simplified is y = -x/2 - 6

Perpendicular slopes are just reciprocals of the original slope, so just flipp the original slope around to be the complete opposite.

Example if slope= -2, the reciprocal= -1/2

Just flip the numerator with the denominator for perpendicular slope

Solve the equation<br>-2x + 1 = -4x + 9<br>x=​
Vinil7 [7]

Answer:

x = 4

Step-by-step explanation:

Step 1: Write equation

-2x + 1 = -4x + 9

Step 2: Solve for <em>x</em>

  1. Add 4x to both sides: 2x + 1 = 9
  2. Subtract 1 on both sides: 2x = 8
  3. Divide both sides by 2: x = 4

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

-2(4) + 1 = -4(4) + 9

-8 + 1 = -16 + 9

-7 = -7

HELP ASAP PLZ PLZ PLZ I GIVE BRAINLIEST
Yuki888 [10]

Answer:

12

Step-by-step explanation:

We can see that the base TA is 4, and the second base RS is 2. We can see that the height is 4. The area of a trapezoid is:

A=\frac{h(b_1+b_2)}{2}

Using this, we can substitute, and get:

A=\frac{4\cdot(2+4)}{2} = \frac{24}{2} = 12

Hope it helps!!

Which one is bigger and how do you know? 1/8 or 1/9 (Give at least two strategies) i​
scoray [572]

Answer:

1/8 is the bigger fraction

Step-by-step explanation:

When comparing fractions with different denominators, and the numerator is one, like 1/8. The one with the smaller number for the denominator is greater.

You could also compare them by finding common denominators, so for 1/8 and 1/9, a common denominator would be /63. So you would take \frac{1}{8} and multiply that by \frac{9}{9}. You would then get \frac{9}{63}. When you take \frac{1}{9} times \frac{8}{8} you get \frac{8}{63}. So when comparing you can see that 1/8 is greater than 1/9.

Write the ratio<br> 3/5 to 9 as a fraction in simplest form.
larisa [96]

Answer:1/10

Step-by-step explanation:

To convert a ratio to a fraction, you divide the number on the left by the number on the right. This gets you (3/5)/6. When dividing fractions by whole numbers, you need to convert the whole number to a fraction. I converted 6 to 6/1, so that gave me (3/5)/(6/1). You then multiply the top number by the bottom number to get the numerator of the answer, and the middle 2 numbers multiplied is the denominator. The answer is (3x1)/(5x6), or 3/30, which can be simplified to 1/10.
