hope this helps <3
Answer:
x>2
Step-by-step explanation:
Answer:
y = 7 and x =3
Step-by-step explanation:
use elimination method
so we gonna eliminate y first
9x = 1 - 4y
-7x = -7 + 4y
7| 9x = 1 - 4y
9| -7x = -7 + 4y
63x = 7 - 28y
-63x = -63 + 36y
add eqtn 1 to eqtn2
you will get
0 = -56 + 8y
56 = -56 + 56 + 8y
56 = 8y
56÷8 = 8y÷ 8
7 = y
also eliminate x as we have done wth y
4| 9x = 1 - 4y
4| -7x = -7 + 4y
36x = 4 - 16y
-28x = -28 + 16y
add the two equations
u will get
8x = -24 + 0
8x = -24
8x÷8 = 24÷ 8
x = 3
Assuming these lines are perpendicular
Opposite angles are congruent therefore
77 = 6x + 23
6x = 54
X = 9
And supplementary angles sum up to be 180 degrees where in this case we can take angle 77 degrees and z which makes
77 + z = 180
Z = 103 degrees
Therefore,
x = 9 degrees
z = 103 degrees
Answer:
7 fishes
Step-by-step explanation:
Given the growth of the population of fish which is modeled by the exponential function:

Where:
t=time in weeks after release
b=growth rate of the fish
At t=0

The initial number,
of fish which was released into the lake is 7.
