The function F(t) = 34000(.98)^t, since b = 0.98 < 1, hence the function is decaying and the initial value of the expression is 34,000.
<h3>Exponential equation</h3>
The inverse of exponential equation is logarithmic equation. The standard exponential equation is expressed as;
y = ab^x
where
a is the initial value
b determine the growth rate or decay.
If the value if b < 1, then it is a decay otherwise it is growth.

Answer:
x = -2; y = 3
Step-by-step explanation:
5x + 4y = 2 (1)
3x + 3y = 3 (2)
Multiply (1) by 3 and (2) by 4
15x + 12y = 6 (3)
12x + 12y = 12 (4)
Subtract (4) from (3)
15x - 12x = 6 - 12
3x = -6
x = -6/3
x = -2
Substitute x = -2 into (1)
5x + 4y = 2
5(-2) + 4y = 2
-10 + 4y = 2
4y = 2 +10
4y = 12
y = 12/4
y = 3
The first error is when he multiplied equation (2) by 4
He didn't multiply the right hand side of the equation by 4
3x + 3y = 3 ×4
12x + 12y = 12
But he wrote
12x + 12y = 3
The the next error is subtracting the left hand side of the equation and adding the right hand side
15x + 12y = 6
12x + 12y = 3
He wrote
3x = 9
Instead of 3x = 3
I think it’s B.
But I’m sure

Answer:
A. (1, -2)
Step-by-step explanation:
We can substitute the variables of x and y into the inequality of
.
Let's start with A, -2 being y and 1 being x.

The absolute value of 1 is 1, and negating that gets us -1.

Indeed, -2 is less than -1! So A is a solution to the inequality.
Let's test the rest of them, just in case.
For B:

Absolute value of 1 is 1, negating it is -1.

-1 is EQUAL to -1, not less than it, so is not a solution to the inequality.
Let's try C.

Absolute value of 1 is 1, negating it is -1.

0 is GREATER than -1, so that is not a solution to the inequality.
Hope this helped!
