Answer:
perpendicular
Step-by-step explanation:
First we need to dtemine the slopes of the line
For line 1
L1: (-4, 6) (-3,-1)
m1 = y2-y1/x2-x1
m1= -1-6/-3+4
m1 = -7/1
m1 = -7
For line 2:
L2: (8,9) (15, 10)
m2 = 10-9/15-8
m2 = 1/8
Take their product
m1 * m2 = -7 * 1/7
m1m2 = -1
Since the product of their slopes is -1, hence they are perpendicular
You can use proportions to solve this.
Cross multiply
Divide by 4
Now solve
There are 280 dolls
Answer:
i think its 70 but i might be wrong pls let me know in the comments if i am right or wrong
Step-by-step explanation:
For this equation, all are subtraction symbols which means you don't need to care about the parenthesis as they do nothing.
Basically, it's the associative property because the parenthesis do nothing to the equation and both sides stay the same
