When x = -3, the answer is 13
when x = 0, the answer is 4
when x = 5, the answer is -11
what i did to get this was use 4-3(x) don’t look at the g(x), it’ll just confuse you
replace the x with the x they provide you to get each answer
ex: 4-3(-3) =13
Hello,
Let's assume t the time for counting one step
V the girl velocity in t
v the escalator velocity in t
d the length to go upstairs
going up: V*60+v*60=d
walking down: V*90-v*90=d
so
V+v=d/60
V-v=d/90
2V=d*5/180
V=d*5/360
V=d/72
V*72=d The girl must count to 72 steps.(here v=0)
Answer:
<em>x = 12 and y = 16</em>
Step-by-step explanation:
Given the following lengths;
NO = x + 2y,
MO = 3x,
PQ = 6x + 4, and
OQ = 2y + 4.
The following postulates are true;
MN = PQ
Since MO + ON = MN
MN = 3x + x+2y
MN = 4x + 2y
Recall that PQ = 6x+4
Equating both expressions;
4x + 2y= 6x+4
Collect like terms;
4x-6x + 2y = 4
-2x + 2y = 4
x - y = -4 ...... 1
Also MO = OQ
3x = 2y + 4
3x-2y= 4 ....2
from 1; x = -4 + y
Substitute into 2:
3x-2y= 4
3(-4+y)-2y = 4
-12+3y-2y = 4
-12+y = 4
y = 4 + 12
y = 16
Since x = -4+y
x = -4 + 16
x = 12
<em>Hence x = 12 and y = 16</em>

Answer: I don’t know the choices, but a line parallel to that equation must have a slope of 3/8 when simplified into slope-intercept form.
Slope-intercept form: y = mx + b
Solving:
3x - 8y = 12
-8y = -3x + 12
y = 3/8x - 1 1/2
Answer:88
Step-by-step explanation: cause it say 88 students in class then it say how many students per class its 88 i think
