Answer:
x=2.2
y=-3.4
Step-by-step explanation:
subtract the second from the first
-5x=-11
x=2=2
substituting by x in the first equation
so y=-3.4
Answer:
$3.30
Step-by-step explanation:
2.60*6= $15.60 beads per necklace
35.40-15.60= $19.80 total pendant
19.80/6= $3.30 per pendant
Hi there, just multiply all 4 numbers. 5.3*8*8*4=1356.8
The answer to this question is 5.2
f(x) = (3x+5)/7
Step 1:
we write f(x) as y
y=(3x+5)/7
Step 2:
switch y by x and x by y
x=(3y+5)/7
Step 3:
solve for y,
x=(3y+5)/7
multiply both sides by 7
7x=3y+5
subtract 5 from left side
3y=7x-5
divide both sides by 3
y= (7x-5)/3
f⁻¹ (x) =(7x-5)/3
