16) you are right
3x-4=2x+6
x=10
17)
1st segment = x
2nd segment = 2x
3d segment = 4x+3
equation x+2x+4x+3=38
7x = 38-3
7x=35
x=5
First segemnt = 5 inch
2nd segment 2x = 2*5 = 10 inch
3d segemnt 4x+3=4*5+3=23 inch
Answer:
3360
Step-by-step explanation:
(77x80)-(175+600+2025)
Answer:
B-250
Step-by-step explanation:
for every 6% count by 15s and once you hit 240(96%) there is a remaining (4%) so just add 10 and you get the whole 100%
y = - 
(x - 5)² + 4
the equation of a quadratic in standard form is
y = a(x - h)² + k ( where (h , k ) are the coordinates of the vertex and a is a multiplier )
given vertex = ( 5, 4 ) then
y = a(x - 5)² + 4 ( to find a substitute (7 , 1 ) into the equation )
1= 4a + 4
4a = - 3 ⇒ a = -
y = - (x - 5)² + 4 ← ( in vertex form )
Answer: not sure what the character in front of the 7 is
if the equation is 7-y= 6 then y= 1
if the equation is something else please tell me so i can help :)
