Solution: f(18.5)=31.47
Step by step solution:
I started by making an equation in slope intercept form- I found the slope, 28/17, with the points (4, 17) and (12.5, 31). Then I found the y intercept, 1, with the point (4, 17). So the equation is y=28/17x+1. Then I just plugged 18.5 where the x is and solved for y
28/17(18.5)+1=y
28/17(37/2)+1=y
1036/34+1= y
30.47+1=y
y=31.47
Keep in mind that 1036/34 is not exactly 30.47 but that 30.47 was rounded to the nearest hundredth
Hope this helps :)
Answer:
3a²b
Step-by-step explanation:
The product of two algebraic
terms is 6a3b2. If one of the terms is
2ab, find the other term.
Let us represent
First term = a
Other term = b
a × b = 6a³b²
a = 2ab
b = ?
b = 6a³b²/a
b = 6a³b²/2ab
b = 6a³b²/2a¹b¹
b = (6 ÷ 2) × a^3 - 1 × b ^2 - 1
b = 3a²b
Therefore, the other term = 3a²b
Answer:
Step-by-step explanation:
p = power washer and g = generator
6p + 6g = 90 .....multiply by 4
4p + 8g = 100 ....multiply by -6
---------------------
24p + 24g = 360 (result of multiplying by 4)
-24p - 48g = -600 (result of multiplying by -6)
---------------------add
-24g = - 240
g = -240 / -24
g = 10 <=== the generator cost $ 10 per hr
6p + 6g = 90
6p + 6(10) = 90
6p + 60 = 90
6p = 90 - 60
6p = 30
p = 30/6
p = 5 <==== the power washer costs $ 5 per hr
check...
4p + 8g = 100
4(5) + 8(10) = 100
20 + 80 = 100
100 = 100 (correct)
I dont know exactly what your asking but x=-y-2
You divide everything by 2.
Your answer is
Y=1/2 + 3/2
