Its simple, graph them.
For the first equation, go on the Y-Axis (the vertical one) and go to 4. Then from there go up 1, right 6.
For the second equation go on the Y-Axis (the vertical one) and plot a point at 1 (aka 0,1) Now you go up 1, right 3.
When you see an equation like y=2x+3, the 3 represents the point (0,3) as when the x is 0, y=3. Just plug the numbers in. And as for the "2x" 2 is the slope. Slope is always rise/run or up, then right. So if its 2 your slope is 2/1, rise 2, over 1. If it "-2x" is your slope then all you have to do is go down 2, right 1.
I hope this cleared up your confusion, brainliest/heart would help.
Answer:
1 = 52°
2=79°
3= 38°
Step-by-step explanation:
each triangle equals 180°
and 1 and 3 also make a right angle which should always be 90°
Answer:
<h3>3/20*200</h3>
=5*3
=15%
the percentage of the number is 15%
Answer:
Step-by-step explanation:
Given that a referral code is 2 letters (A-Z, no lowercases) followed by 4 digits (0-9), or it is 2 digits (0-9) followed by four letters (A-Z, no lowercases).
Digits are not allowed to repeat but letters can repeat.
Thus we find that 2 letters can be selected in
Since for numbers repitition is not allowed, 4 digits can be arranged in 9P4 ways
= 9*8*7*6
Total no of ways for I type=
For II type numbers are 2 and letters are 4.
So no of ways =
total referral codes possible =
Answer:
70
Step-by-step explanation:
Complementary angles equal 90 degrees
90 - 20 = 70
