Answer:
<u>2(3x + 4)</u>
Step-by-step explanation:
2 x 3x = 6x and 2 x 4 = 8
Answer:
g(x)=2x-3÷5
g=-11 as give by question
x=9 as give by question
-11×9=2×9-3÷5
-99=18-3÷5
-99=15÷5
-99=3
=3+99
=102#
Answer:
y= 36
Step-by-step explanation:
if y varies directly as x, and y=9 when x=4, find y when x=16
.
When you see "direct variation" think:
y = kx
.
To find k, use "y=9 when x=4":
y = kx
9 = k(4)
9/4 = k
.
so, our equation is:
y = (9/4)x
.
now, we can answer:
find y when x=16
y = (9/4)x
y = (9/4)(16)
y = (9)(4)
y = 36
Answer:
x>-2
Step-by-step explanation:
to get the -3x alone, we have to subract 1 from 6
7-1 = 6
-3x<6
6/-3 = -2
flip the symbol since we divided by a negative number
x> -2
