Put the values as coordinates (x,y)
(1, 5) and (2, 7)
Find the slope:
(7-5)/(2-1)
m=2
Find the y intercept:
y=mx+b
y=2x+b
5=2(1)+b
b=3
<span>b.) y = 2x + 3
</span>
Hope this helps :)
His/her birthday is in the leap year which only happends every 3yrs he was born February 29
We have
First, we can combine like terms 3y and -7y to get -4y.
Then, we have
We could then subtract 8 on both sides to get
Finally, we isolate y completely by dividing both sides by -4, to get
Answer:
x= 2.5
Step-by-step explanation:
We can use ratios to solve
AB AD
------- = ----------
AC AE
X 5
------- = ----------
x+1 7
Using cross products
7x = 5(x+1)
Distribute
7x = 5x+5
subtract 5x
7x-5x = 5x-5x+5
2x= 5
Divide by 2
2x/2 = 5/2
x = 2.5
