Answer:
a. =11+ 1
b. =4x+ (-7y) + (-5z) +6
c. (-3x) + (-8y) +(-4)+(-8/7z)
Step-by-step explanation:
a. 20 - 9 + 8 -7
=11+ 1 ( this is obtained by solving)
b. 4x - 7y - 5z + 6
=4x+ (-7y) + (-5z) +6
We multiply the negative sign with the positive sign to get a minus so the answer remains the same and the expression is written as an addition sum.
c. -3x - 8y - 4 - 8/7z
-[ 3x+8y+4+8/7z]
or
(-3x) + (-8y) +(-4) +(-8/7z)
The minus sign is taken as common leaving the expression with the plus only.
It can be written in the same manner as above, adding the negative terms so that the expression is written as a sum.
Answer:(12,-5)
Step-by-step explanation: if you have (x-12)^2+(y+5)^2=100 you switch the signs of 12 and 5 opposite
Answer:
4
Step-by-step explanation:
g(x) = 12(2)x - 1
h(x) = 3x
We are looking for this :
g(6) * h(6) ....so we have....
12(2)6-1 * 36 =
12(2)5 * 729 =
12*32 * 729 = 279,936 points
The answer would be 34/100 or 17/50 if reduced .
