Alright,
-9/10x + y = 1 1/10
C) -2 and 4 because it crosses over the x - axis
Answer:
The value of
is -16.
Step-by-step explanation:
We need to evaluate
for x = -1, y = 5 and let us assume that z = 1
It can be simply done by putting the values of x,y and z in the given expression.

We know that the value of 4² = 16
So,

So, the value of
is -16.
Answer:
535
Step-by-step explanation:
8 x 7 = 56
15 x 17 = 255 . 255 / 2 = 127.5
15 x 17 = 255 . 255 / 2 = 127.5
15 x 7 = 105
17 x 7 = 119
119 + 105 + 127.5 + 127.5 + 56 = 535
Answer:
T = 125 +116.40N
Step-by-step explanation:
The total savings is the sum of the two plan values:
T = A + B
T = (125 +40.75N) +(75.65N) . . . . substitute the given formulas
T = 125 + (40.75+75.65)N . . . . . . .combine like terms
T = 125 +116.40N
