Answer:
It's 7
Step-by-step explanation:
w(2) = 4 * 2 - 1 = 8 -1 = 7
Alright, so the hard part here is probably setting up the proportion. Well, the first proportion is 6 cups of water to 4 cups of flour, which will look like this:
.
Now you'll have to set up the second proportion, since you're gonna use 6 cups of flour. So the second proportion will look like this:
. x is the number you'll be solving for.
Set the two proportions equal to each other and solve for x. Good luck!
Answer:
Step-by-step explanation:
Hi there!
<u>What we need to know:</u>
- Slope-intercept form: where <em>m</em> is the slope and <em>b</em> is the y-intercept
- Perpendicular lines always have slopes that are negative reciprocals (examples: 1/2 and -2, 3/4 and -4/3)
<u>1) Determine the slope (</u><u><em>m</em></u><u>)</u>
Reorganize the given equation into slope-intercept form; subtract 2x from both sides to isolate <em>y</em>:
Now, we can easily identify the slope of the line to be -2. Because perpendicular lines always have slopes that are negative reciprocals, the slope of a perpendicular line would be . Plug this into :
<u>2) Determine the y-intercept (</u><u><em>b</em></u><u>)</u>
Plug in the given point (2,5) and solve for <em>b</em>:
Subtract 1 from both sides to isolate <em>b</em>:
Therefore, the y-intercept of the line is 4. Plug this back into :
I hope this helps!
Answer:
Option B
Step-by-step explanation:
To solve this, the Pythagorean Theorem is needed. For option A, to make the statement true, 4 squared plus 7 squared MUST equal 9 squared. So, if you take 16 and add 49 to it you do NOT get 81.
For option B, 5 squared plus 12 squared is the same as 25 plus 144. That equals 169, which IS 13 squared.
It is not option C because 20 squared plus 22 squared doesn't equal 24 squared
