Answer:
y=7/4x+15/4
Step-by-step explanation:
y-2=7/4(x+1)
1) Distribute 7/4 to x and 1:
y-2=7/4x+7/4
2) Add 2 to both sides:
y=7/4x+15/4
Let's say Ralph can do the chores in h hours, and Jo in 2h. Then:
1/h+1/2h=1/6
6+3=h
h=9
Ralph takes 9 hours working alone; Jo takes 18 hours

Answer:
The amount is $8358.7 and the interest is $3858.7.
Step-by-step explination
STEP 1: To find amount we use formula:
A = P
1 +
r
n
n·t
A = total amount P = principal or amount of money deposited, r = annual interest rate n
= number of times compounded per year t = time in years In this example we have
P = $4500 , r = 7% , n = 2 and t = 9 years
After plugging the given information we have
A = 4500
1 +
0.07
2
2·9
A = 4500 · 1.03518
A = 4500 · 1.857489
A = 8358.7
STEP 2: To find interest we use formula A = P + I, since A = $8358.7 and P = $4500 we
have:
A = P + I
8358.7 = 4500 + I
I = 8358.7 − 4500
I = 3858.7

A circle with two chords is given with length X, 8, x-12, 12. Thus, The value of x is 24.
<h3>What is the relation between line perpendicular to chord from the center of circle?</h3>
If the considered circle has center O and chord AB, then if there is perpendicular from O to AB at point C, then that point C is bisecting(dividing in two equal parts) the line segment AB.
Or
|AC| = |CB|
Using the theorem of intersecting chords
The value of x is 24.
