Answer:
75 dollars a month
Step-by-step explanation:
To find The amount we need to divide 600 by 8 which gives us 75
Answer:
It decreases by 4 units
Step-by-step explanation:
Answer:
all values stand for 3x+(-5)=19
- 3x-5=19=> 3x=24=> <u>x=8</u>.
Three step requires another step, so it is difficult than two step process.
no, their is no limit to the number of steps it take to solve an equation.
Every number can be described as a sum/difference of two or three numbers.
Carry out the mult.: f(x) = -[x^2 - 21x + 9x - 189]
Combine like terms: f(x) = -[x^2 - 12x - 189]
Eliminate the brackets [ ]: f(x) = -x^2 + 12x + 189
Identify coefficients a, b and c: a= -1, b=12, c=189
The equation of the axis of symmetry is x = -b/(2a), which here equals
x = -(12)/[2(-1)], or x = 6
This is also the x-coordinate of the vertex. Plug x=6 into the original equation to calculate the y-coordinate.
