Answer:
15
Step-by-step explanation:
Both triangles are congruent, so RS and JI have a 1:5 ratio.
3 x 5 = 15 for HI
The sector area is = pi * r^2 (circumference/360). Do the work inside the () first and then multiply by pi r^2
Slope intercept form is y=mx+b where m is slow and b is y intercept. since we dont have this info we will have to do some work to solve.
1. find slope. this is change in y du used by change in. so we take the two points given and subtract the y values and divide by difference of x values
m=(8-2)/(-3--1)=6/-2=-3
2
use point slope formula and simplify. this is y-y1=m(x-x1) where (x1,y1) is a point on the l in ne. you can pick either point it doesn't matter. we will use (-1,2)
y-2=-3(x+1)
simplify to slope intercept by solving for y
y-2=-3x-3
y=-3x-1
so we have slope -3 and y intercept -1
Answer:
x = 10
Step-by-step explanation:
61 - 21 = 40
40 / 4 = 10
x = 10
Answer:
Parallel
Step-by-step explanation:
The equation of a line in slope - intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Both given equations are in this form, that is
y = 
x + 1 → m =
y = x - 7 → m =
Parallel lines have equal slopes thus the lines are parallel
