The model says a=.25t+29
a) since 1995 is 25 years after 1970 we have
a=.25*25+29=6.25+29=35.25 yrs old
b) since 2015 is 45 yrs since 1960 we have
a=.25*45+29=11.25+29=40.25, or 40.3 rounded to the nearest tenth
Answer:
Spencer and Abigail are correct
Lauren is incorrect
Step-by-step explanation:
Spencer and Abigail are correct
Slope = change in y ÷ change in x
Or 
Let
= (3, -1)
Let
= (5, 4)

This is Spencer's method
Let
= (5, 4)
Let
= (3, -1)

This is Abigail's method
It doesn't matter which point you label as point 1 and point 2, as long as you carry out the slope calculation correctly.
Lauren's calculation is wrong as she calculated her slope as:
where it should have been 
Answer:
1/16
Step-by-step explanation:
Given the expression;

To find a constant that will make it a perfect square, we will use the square if the half of coefficient of x
Coefficient of x = 1/2
half of Coefficient of x = 1/2*(1/2)
Half of Coefficient of x = 1/4
square of the half of coefficient of x = (1/4)^2
square if the half of coefficient of x = 1/16
hence the constant that will make it a perfect square is 1/16
X+y=23 (x and y added equal the number of baskets made)
2x+3y=53 (since each basket is worth a certain amount of points, x and y must be multiplied by their amount of baskets and added together to get the total number of points)
Hope this helps!
Answer:
54
Step-by-step explanation:
Each vertex of the pentagon has an angle of 108 degrees. So, x = 108/2 = 54
