It is given that
a+b=20 -------------------- (1)
b+c=30 -----------------------(2)
We have to calculate
3 a + 4 b +7 c
Now multiplying equation(1 )by 3,we get
3 a+ 3 b=60 ----------------------------------(3)
and Multiplying equation( 2) by 4,we get
4 b + 4 c=120 -----------------------------------(4)
Adding expression (3) and (4),we get i.e left hand side of 3 to left hand side of 4 and right hand side of 3 to right hand side of 4.
3 a+ 3 b+ 4 b+ 4 c=60+120
Adding like terms, we get
3 a+ 7 b+ 4 c =180, Which is the required solution.
Answer:
i think its c
Step-by-step explanation:
Answer:
0
Step-by-step explanation:
Slope is Rise over Run (y / x).
For 2 points, you would take the difference of y-coordinates and divide by the difference of x-coordinates.
(Y1 - Y2) / (X1 - X2)
Since both y-coordinates are the same (ten minus ten), your slope is zero (zero divided by anything is zero).
Answer: No mistakes was made
Step-by-step explanation:
Because It all equals the same as the answer
Answer:
a) The graph shifted to the left by 3 units and up 1 unit.
b) Domain = x ∈ R Range = y ∈ R
(Domain (x) = All real numbers Range (y) = All real numbers)
c) (-4, 0)
d) (0, 2.442)
