Answer:
20 and 60
Step-by-step explanation:
20 x 3 = 60
20 + 60 = 80
1) The standard form of the equation given is y = mx+b, now you must development the equation given in form point-slope to standard form
Y-1 = 2/3(x-2) ,⇒y = 2/3x-4/3+1 ⇒y =2/3x-1/3
Answer: 3.8
Step-by-step explanation:first, you need to figure out what side you’re looking for. Side AC is opposite of the angle you’re given. They also give you length of side AB which is 4. That is the hypotenuse (side directly across from right angle). So, you have the hypotenuse, and need the find the opposite side measure. Which option uses opposite and hypotenuse? That’s Sin. So, you would do: sin70 = ? / 4.
sin (of given angle)= opposite / hypotenuse.
Sin (70 degrees) = ? / 4
Then you solve for “?”
Type sin70 into your calculator, then multiply both sides by 4 to get “?” by itself. You should get 3.758770483, which rounds to 3.8
5 and 6/7 equals 5 and 12/14 and 11/2 is 5 and 7/14 and if you subtract, you get 5/14.
For the first one, I find it easiest to work backwards. This means you do the opposite of what it says So start with 24 and add 3. This gives you 27. Then, divide by 3. This means the answer is 9.
The second one. You do (y2-y1)/(x2-X1). Plug in the numbers and you end up with -12/-3 which is equal to four.
