Answer:
+ 1
Step-by-step explanation:
Given
x² + 2x = 9
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(1)x + 1² = 9 + 1²
(x + 1)² = 10
Answer:
(2*5) 3*7-1*6÷3*2+1*4÷2*5=216
Answer:
it is 84
Step-by-step explanation:
Answer:
Yes
Step-by-step explanation:
Multiply one eqution so that they are same.
For example:
2x+17y+48=0
x+8y-6=0 --> multiply 2 times, so 2x+16y-12=0
and now you can use it as if they are coefficients for both variables
Answer: y = 1/2x - 6
Step-by-step explanation:
#4 We are going to use slope intercept form, (y = mx+b)
1. The line crossing the y-intercept at (0,-6)
2. The slope is 1/2 (increasing by 1 then over 2 --> RISE OVER RUN)
3. Make the equation: y= 1/2x - 6
