9 × 9 = 81
9 plus itself 9 times equals 81
the nines table goes 9,18,27,36,45,54,63,72,81,90
To check the two numbers add up to 9 for 1-10 multiples
Algebra would be m × m =m^2
^means to the power and the 2 means we are doing it to the power of two [Also known as squaring]
This works because they are both the same number
Answer:
The lateral area is 
Step-by-step explanation:
we know that
The lateral area of a right prism is equal to
where
P is the perimeter of the base of the prism
H is the height of the prism
in this problem we have
substitute
Here is how to find the intercepts, if the graph is hovering above the x axis (k<0) there will be no real solutions for the x intercept
Answer:
2. y = 7/2 x -2
3. y = 3/4x-1
Step-by-step explanation:
points (0,-2) (4,12)
slope = (y2-y1)/(x2-x1)
slope = (12--2)/(4-0)
= (12+2)/4
= 14/4 = 7/2
the slope is 7/2 and the y intercept is -2
y = mx+b
y = 7/2 x -2
points (0,-1) (4,2)
slope = (y2-y1)/(x2-x1)
slope = (2--1)/(4-0)
= (2+1)/4
= 3/4
the slope is 3/4 and the y intercept is -1
y = mx+b
y = 3/4x-1
