I'm not sure about d.
This was what I could come up with.
Answer:
15
Step-by-step explanation:
First, solve for Line 1
3x + 4y = -14
<em>move the x to the right of the equation</em>
4y = -3x - 14
<em>divide the whole equation by 4 </em>
y = -3/4x - 14/4
<u>Line 1 is y = -3/4x - 7/2 </u>
Then, solve for Line 2
Since Line 2 is perpendicular, change the sign of the slope of Line 1 and then get the reciprocal of that.
-3/4 to 3/4 to 4/3
4/3 is the slope of Line 2.
Now, we want to find what the b of the equation is, so we can plug in our x (-5) and our y (7) into the y=mx+b equation to find b. The 4/3 is the m or the slope.
y = mx + b
<em>plug in the y, m, and x into the equation</em>
7 = (4/3)(-5) + b
<em>multiply the m and x together </em>
7 = -20/3 + b
<em>add 20/3 to both sides so it will cancel out on the right of the equation and be added to the 7 on the left of the equation</em>
<u>41/3 = b </u>
So, m = 4/3 and b = 41/3
Add them together and you get 45/3 or 15.
I hope this helped!
Answer:
(2 , 4)
Step-by-step explanation:
set 3x-2 = -x + 6
4x = 8
x = 2
3(2) - 2 = 4
1 is an odd number so let’s put 1 into n, (1)2+4 which equals 2+4 which is 6, 6 is not a prime number as it can has factors such as 2&3 not just 1&6.
Answer:
- <u>Quantitative.</u>
- <u>Discrete.</u>
- <u>Interval Scale.</u>
Step-by-step explanation:
- The IQ scores are measured numerically. This makes it quantitative data. Quantitative data provide numerical measures which can be used to perform arithmetric operations such as addition, subtraction, multiplication and division. Results from these kind of data can be used to provide meaningful and explanatory results to certain phenomena.
- IQ scores are discrete because they are always expressed as integers. that is in whole numbers and not in fractions e.g 100, 120, 60.
- The level of measurement is on an interval scale because the difference between values have meanings. Larger values mean higher IQ. for example, the difference in IQ numbers between two people for represents something real.
