Hi there!
To find your answer, simply sub in the point and the slope into y-y1=m(x-x1) for y1, x1 and m!
m=-8
point: (1,-8) use this point for x1 and y1
y+8=-8(x-1)
Therefore your equation is y+8=-8(x-1)
Hope this helps!
Answer:
the last one
Step-by-step explanation:
I think maybe
So 22.5 per barrel
so 22.5
x represents the number of 22.5 barrels
y represents the number of 35 barrels
so
x+y=1250
then find the total cost
1250 barrels
27.5 per so mutiply by 1250 and get 34375 total cost
22.5x+35y=34375
we have 2 senctances
x+y=1250
22.5x+35y=34375
elimination
mulitply first equation by -35 to clear y
-35x-35y=-43750
add to second equation
-35x-35y=-43750
<u>22.5x+35y=34375 +</u>
-12.5x+0y=-9375
-12.5x=-9375
multiply -1
12.5x=9375
divie both sides by 12.5
x=750
subsitute
x+y=1250
750+y=1250
subtract 750
y=500
750 barrells of the 22.5 oil should be included and
500 barrells of the 35 oil should be included
1130.9734
volume=πr2h
π x 6 x 10= 1130.9734
Answer:
The value of y = 62°
and x = 50°
Step-by-step explanation:
=> 57° + y + 61° = 180°
=> 118° + y = 180°
=> y = 180° - 118
=> y = 62°
Now ,
x° + y° + 67° = 180° { sum of angles of a triangle is 180° }
=> x° + 62° + 68° = 180°
=> x + 130° = 180°
=> x = 180° - 130°
=> x = 50°
