Answer:
y-1=x^2
Step-by-step explanation:
That is the equation of a parabola with vertex at (0,1). The equation is y-1=x^2.
Answer:
x=70
y=75
Step-by-step explanation:
2x+x+5-35=180
3x-30=180
3x=210
x=70
2(70)-35=105
180-105=75
y=75
Answer: $40+$10x
Step-by-step explanation:
1. We already know he has $40.
2. 10x represent the 10 dollars he is paid per month.
Gradient is synonymous to slope.
y = 6x + 5 is an example of a slope-intercept form of a straight-line equationl.
The slope-intercept equation is like this:
y = mx + b
where : m = slope ; b = "y-intercept"
y = 6x + 5
6 is the slope
5 is the y-intercept.
Since slope and gradient are synonymous, 6 is the gradient of the above equation.
The first sentence is irrelevant information, you can ignore that!
There are 20 players. Each player paid the <em>same amount. </em>
In total, they payed $500,000.
We need x, the amount a single player pays. x times 20 will give us 500,000. This gives us the equation 20x=500,000
Divide both sides by 20 to isolate the variable.
x=25,000
