4x-2y=7 (1)
-3x+3y=10 (2)
3y= 3x+10
y= x+10/3 (3)
sub (3) into (1)
4x-2(x+10/3)=7
4x-2x-20/3=7
2x-20/3=7
+20/3 +20/3
2x= 41/3
x= (41/3) / 2
x= 41/6
sub x= 41/6 into (3)
y= 41/6+10/3
= 61/6
Therefore the point of intersection is (41/6, 61/6)
Hi, Sthefy! This is just a little bit of adding, not too hard! Okay, 5 tens. What is 1 ten equal to? 10!
2 tens? 20!
3 tens? 30!
You get the idea? Okay, so now we know that 5 tens are 50. Now, ones. All we need to do now is add 13 + 50! Let's break it down, make it easier.
13.. Hm, what can we do to make this easier?
Ah! Take away the 3 from 13 for now. So just 10 + 50. That's 60. Now, add the 3. 63! That wasn't hard, was it? I hope I helped you!
Answer:
11 1/5
Step-by-step explanation:
3 1/5 ÷ 2/7 =
16/5 ÷ 2/7 =
KCF (Keep, Change, Flip)
Keep 16/5
Change ÷ to ×
Flip 2/7 to 7/2
16/5 × 7/2
16 x 7 = 112
5 x 2 = 10
112/10
11 2/10
11 1/5
Hope that helps :)
Answer: 6 1/6 , 5.5, 4 3/8, 4.3, 3.75
Step-by-step explanation:
4.3 , 5.5 , 36, 3.75, 4.375
Answer:
1
Step-by-step explanation:
Y=mx+b
so find your slope
y2-y1/x2-x1 so 13-7/4-2
you get 6/2 or simplified 3
so now you have the equation y=3x+b
next you want to plug in a point to your equation so
7=3(2)+b
now solve using PEMDAS
7=6+b
then you want to isolate your variable
7 = 6 + b
-6 -6
1=b and thats your slope intercept
hope this helped :)
