Answer:
Yes.
Step-by-step explanation:
The x and y values are the same. The equation states that x and y have the same value.
The point (3, 3) satisfies the equation y = x.

The y-intercept of the first question is 1 and it represents the number of minutes they stretch when they don't jog.
#4) y=1/2x + 1
#5) 10 cakes, because y=9/10x+1
Explanation
For the first question: The y-intercept is easily picked from the two points that define the line. (0, 1) would have to be on the y-axis, because when we plot it, the x-coordinate is 0. This means it is the y-intercept of the line.
#4) Finding the slope of the line, we use the formula
m=(y₂-y₁)/(x₂-x₁) = (3-1)/(4-0) = 2/4 = 1/2
The y-intercept is at (0, 1), using the same justification as the first question.
This gives us the equation y = 1/2x + 1.
#5) First we find the equation of the line. To do this, find the slope:
m=(y₂-y₁)/(x₂-x₁) = (10-1)/(10-0) = 9/10
The y-intercept is at (0, 1). This makes our equation y=9/10x + 1.
Using 10 as x (x represents the number of weeks) we have
y=9/10(10) + 1
y=9/10(10/1) + 1
y=90/10 + 1
y=9+1 = 10
Answer:
The perimeter is 70
Step-by-step explanation:
Isosceles means all sides same length. So to start out, you need to firgure out x so you can do let's say 3x-5=19x, or you can do 2x=19-x, or an combination pretty much. Once completing this, you find that x=14. Now all you have to do is plug 14 into all the x spots, and add everything together
Hope it helped :-)
