Slope-intercept form of a line:
y=mx+b
m=slope
other perpendicular line to this line (y=mx+b) will have the next slope:
m´=-1/m
We have this line in slope-intercet form:
y=1/3x-7
m=1/3
A perpendicular line will have the next slope:
m´=-1/m=-1(1/3)=-3
Now, we have a point (5,-2) and the slope (-3).
point-slope form: given a point (x₀,y₀) and the slope m, the point-slope form will be:
y-y₀=m(x-x₀)
In this case:
y-(-2)=-3(x-5)
y+2=-3x+15
y=-3x+15-2
y=-3x+13
Answer: The equation of a line (slope intercept form) that is perpendicular to the line y=1/3x-7 and passes throught the point (5,-2) is:
y=-3x+13
Step-by-step explanation:
W=-6, x=1.2, and z=-6/7
(W²x-3)÷10-z
we substitute
((-6²)(1.2)-3)÷10-(-6/7)
((-36)(1.2)-3) ÷10-(-6/7)
(-43.2-3) ÷10(6/7)
(-46.2)÷60/7
-46.2÷60/7
-46.2*7/60
-46.2/1*7/60
-323.4/60
-5.39
Answer:
3 dress pants and 3 jeans
Step-by-step explanation:
dress pants cost $80
jeans cost $40
80+40+80+40+80+40= 360
18/100
6/50
3/25
here is a couple different options. the last one being the most simplified. hope this helps
