Answer:
20th day
Step-by-step explanation:
you: 4,8,12,16,20,24
sister:5,10,15,20,25
20 is the day where they meet
So slope intercept form is y=mx+b
m=slope b=y intercept
convert current equation to slpe intercept
y-4=x-8
add 4 to both sides
y=x-4
tada
Answer:
x = 32
Step-by-step explanation:
Using the Secant and Tangent Intersection Theorem we can say;
(x + 18) (18) = 30²
18x + 324 = 900
18x = 576
x = 32
Hope this helps!
Answer:
y = m x + b equation of a straight line
m m' = -1 condition for perpendicular lines
If y = 4 x - 7 then m = 4 so m' = -.25
Y = -.25 X + A we need to find A
A = Y + .25 * 8 = 2 + 2 = 4
Y = -.25 X + 4
Check:
2 = -.25 * 8 + 4 = -2 + 4 = 2
Choice b would be correct since the slope of the line is negative !
