It is 80% just writing random things so it can be 20 words
Answer:
Step-by-step explanation:
f(x) =2x - 7
f( - 3) = 2( - 3) - 7 = - 13
f(3) = 2(3) - 7 = - 1
f(a) = 2a - 7
- f(a) = - (2a - 7) = 7 - 2a
f(a + h) = 2(a + h) - 7 = 2a + 2h - 7
Answer:
Step-by-step explanation:
lets rewrite the equations so that the x and y are on one side and the constant on the other.
2y-x=3
-y+x=0
(we can cancel out the x because one is positive and one is negative)
y=3
(now plug the y value into any equation you want to)
-(3)+x=0
x=3
so our values are
x=3,y=3
175 - (8+45÷3)×7
Using BIDMAS
= 175 - (8+15)×7
= 175 - (23×7)
= 175 - 161
= 14
The positive square root of 35
= 5.9160797831 because 5.9160797831^2 is 35
Therefore you multiply 5.9160797831 to 5.9160797831
