Hey there!
f(x) = 3(2)^x
f(x) = 3(2)^-1
y = 3(2)^-1
y = 3 * 2^-1
y = 3 * 1/2
y = 3/1 * 1/2
y = 3(1) / 1(2)
y = 3/2
y ≈ 1 1/2
Thus, your answer is: y = 3/2 or y = 1 1/2
[EITHER OF THOSE SHOULD WORK BECAUSE THEY ARE BOTH EQUIVALENT TO EACH OTHER]
Good luck on your assignment & enjoy your day!

Write an equation in Point-Slope Form for the given information.
m=4/5;(2,0)
Answer:
y-0 = 4/5(x-2)
Explanation:
0 is the y point so it goes in the y-y1 spot. The m or the slope goes into the m spot by the parenthesis. The 2 goes into the spot of the m-m1. One thing that is important is that when plugging in the point into the equation is to always put in the inverse. So if 3 was the y point, the equation would be y-3, if it was a negative point it would be, y + 3.

What expression is equivalent to (4x–5) (2x-3)?
Answer:
8x^2-22x+15
Step-by-step explanation:
Multiply them together
Answer:
There are many, many, different expressions equivalent, but if you distribute them together you come up with:
8x² - 22x + 15
Step-by-step explanation:
When distributing (4x–5) (2x-3) we should end up with four values, and then add them together.
[] The outside numbers of 4x and -3
-> 4x * -3 = -12x
[] The inside numbers of -5 and 2x
-> -5 * 2x = -10x
[] The left numbers of 4x and 2x
-> 4x * 2x = 8x²
[] The right numbers of -5 and -3
-> -5 * -3 = 15
Now we can add them together;
-12x + -10x + 8x² + 15
8x² - 22x + 15
Have a nice day!

At a certain restaurant, 5 sandwiches and 7 burritos will cost $57.40. In addition, 4 sandwiches and
2 burritos cost $32.60. Assuming that we are talking about the same sandwiches and burritos, what
is the cost of 1 sandwich? What is the cost of 1 burrito? Let x represent the cost of a sandwich
and y represent the cost of a burrito. Show ALL work!
Equation #1:
Equation #2:
Cost of 1 sandwich:
Cost of 1 burrito:
Answer:
sandwich: $6.30burrito: $3.70Step-by-step explanation:
The two relations can be written in general form using the given variable definitions as ...
5x +7y -57.40 = 0
4x +2y -32.60 = 0
The solution using the cross-multiplication method is ...
d1 = (5)(2) -(4)(7) = 10 -28 = -18
d2 = (7)(-32.60) -(2)(-57.40) = -228.20 +114.80 = -113.40
d3 = (-57.40)(4) -(-32.60)(5) = -229.60 +163 = -66.60
x = d2/d1 = -113.40/-18 = 6.30
y = d3/d1 = -66.60/-18 = 3.70
The cost of 1 sandwich is $6.30.
The cost of 1 burrito is $3.70.

What is Simple Interest?Simple interest is a method for figuring out how much interest was paid on a sum of money during a specific time period at a specific rate. Simple interest has a constant principle amount. Simple interest is a clear-cut and simple method for computing financial interest.
We have,
P = $84,410.
R= 15%
T = 4 years
Using Simple Interest
SI = (P x R x T) / 100
SI = (84410 x 15 x 4)/100
SI = 5,064,000
So, the amount is
= 84,410 + 5,064,000
= 5,149,010

A triangle has sides with lengths of 8 feet, 15 feet, and 17 feet. Is it a right triangle?
Answer:
Step-by-step explanation:
To test if this is a right triangle, let's test these side lengths with the Pythagorean Theorem.
a^2 + b^2 = c^2
c is the hypotenuse, the longest side of a right triangle.
a and b are the legs of the right triangle.
a = 7
b = 15
c = 17
7^2 + 15^2 = 17^2 ?
49 + 225 = 289 ?
274 ≠ 289
Thus, this triangle is not a right triangle since it does not satisfy the Pythagorean Theorem.

An angle measures 52° less than the measure of its complementary angle. What is the measure of each angle?
Answer:
Measure of each angle is 71 and 19 degrees.
Step-by-step explanation:
Let's the angle be "n"
Complementary angle = 90 °
n- (90-x) = 52
n - 90+ n = 52
Combine like terms
n - 90+ n = 52
2n-90=52
Add 90 to both sides of the equation
2n-90+90=52+90
simplify
2n = 142
Divide both sides of the equation by the same term
2n/2 = 142/2
Simplify
n = 71
2n = 142
Measure of each angle
1st = 71
2nd = 90-71 = 19
