Answer:
-2 and 2/3
Step-by-step explanation:
(2/3) / (-1/4) is equivalent to (2/3) x (-4/1)
This equals -8/3, of which simplifies down to -2 and 2/3
14x + 7y = 217 > lets solve for y first > so 14(0) + 7y = 217 > 7y = 217 > y = 7/217 > y = 31 > 14x + 7(0) = 217 > 14x = 217 > x = 14/217 > x = 15.5
Now but the 31 in the y place and the 15.5 in the x place and see if it matches up with 217
Answer:
-6
Step-by-step explanation:
Let x =1
F(x)=-x^3-2x^2+7x-10
F(1) = - (1)^3 -2(1)^2 +7(1) -10
= -1 -2 +7-10
= -3+7-10
=-6
Hello from MrBillDoesMath!
Answer: -3/2
Discussion: Assuming neither line is vertical or horizontal the product of the slopes of two perpendicular lines is always -1. We are told the slope of a line is 2/3. The slope of the perpendicular line, "m", is
m * (2/3) = -1
or
m= -3/2
Thank you,
MrB
