Answer:
6x + y = 1
y = 1 - 6x
7x + 2(1 - 6x) = -3 substitute 1 - 6x in for y
7x + 2 - 12x = -3 combine like terms
2 - 5x = -3 subtract 2 from both sides
-5x = -5 divide by -5
x = 1
Answer:
f(6) = 53
Step-by-step explanation:
f(x) = 10x - 7
We want to find f(6)
To do so simply substitute 6 for x in the equation
Equation: 10x - 7
x = 6
f(6) = 10(6) - 7
multiply 10 and 6
f(6) = 60 - 7
subtract
f(6) = 53
The answer is 15/8
simplified: 1 7/8
Answer:
Step-by-step explanation:
(x+30) + (x-23) + (2x-7) = 180 degrees
4x = 180
x = 45
m<1 = x+30 = 75 degrees
m<2 = x-23 = 22 degrees
