I don't think you are an idiot....yo aer a hman.....
I mean " You are a human" Haha we all make mistakes !!
The mother is obviously taller.....so the ratio of mother to baby should be more like 4 to 1
if mother is 4 baby heights then ration of mother to baby is 4 baby heights to 1 baby height or 4 to 1
I get x = 8 also
Multiply the left side by 15 /( z^4 sqrt (14z)) and then reduce everything to find 'x' = 8
I don't think they are points....they are lines between the points....
Y = mx + b form to start....then conver to ax + by form requested
y = 5/3 x + b sub in the given point to calculate 'b'
-3 = 5/3 (4) + b
b = - 29/3
y = 5/3 x - 29 /3 now multiply the entire equation by '3' and re-arrange to the requested form ....
RIGHT click on the blocked image then ' Copy image location' then paste into browser tab.....
From third equation y = 1/4 z + 2.075
From second equation x = 2 - 9/7 z Use these values of 'x' and 'y' in the FIRST equation to solve for 'z'
then the 2nd and 3rd equations will let you calc x and y
There are 3 rectangular sides 10 x 7 6 x 7 and 8 x 7
and TWO triangles TWO x 1/2 6 x 8
add them all together to get ........ m2
rate x time = distance
Yo have the right idea BUT from t= 1 to t = 4 is THREE minutes .....not four.
.5 m/m * 3 min = 1.5 miles
x^2 + 4x + y^2 + 6y = 51 complete the square for x and y
(x+2)^2 + (y+3)^2 = 51 + 4 + 9 this is a circle with center -2 -3 and radius 8
x^2 + 4 + y^2 + 6y = 3
(x+2)^2 + (y+3)^2 = 3 + 4 + 9 this is a circle with center -2 -3 and radius 4 (diameter 8)
