Answer:
I= 1,600
B= 9,600
Step-by-step explanation:
Interest is 8,000 x 0.04(4%) x 5
when you multiply all three (PRT) you end up with 1,600 as your interest.
then your balance is when you add the original borrowed amount ($8,000) with your interest ($1,600).
8,000+1,600= 9,600

Answer:
x = 25º, right scalene triangle
Step-by-step explanation:
The interior angles of a triangle add up to 180º.
The red square indicates the angle measure is 90º.
We are left with two other angles, x and (2x + 15).
Let's set up an equation to represent the angle measures
90 + x + (2x + 15) = 180
First, combine like terms.
90 + x + 2x + 15 = 180
105 + 3x = 180
Subtract 105 from both sides to isolate x.
3x = 75
Divide both sides by 3 to further isolate x.
x = 25º
Let's check our answer by plugging it back into our original equation.
90 + x + (2x + 15) = 180
90 + 25 + (2(25) + 15) = 180
Simplify.
90 + 25 + (50 + 15) = 180
90 + 25 + 65 = 180
115 + 65 = 180
180 = 180
Your answer is correct.
x = 25º
Now we need to classify the triangle.
As stated before, the red square indicates the angle measure is 90º. This means our triangle is a right triangle.
Because the other two angle measures are different from one another, we know that the side measures cannot be equal. This leaves us with a scalene triangle.
Your answer is: right scalene triangle
Hope this helps!

Which expression makes the equation true for all values of x?
16x - 16 = 4( ? )
A 4x - 4
B 4x - 16
C 2x - 2
D 12x - 12
Answer:
A since if we multiply 4 × 4x, we get 16x, and 4 × 4, we get 16, which cancels with the other 16x - 16 on the left side. That makes sure that any x we choose will cancel out in the end.
Step-by-step explanation:
1. 16x - 16 = 4(4x-4)
2. 16x - 16 = 16x - 16
3. 0 = 0

What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
The expression is,
⇒ 4x³
Hence, The value of expression at x = 1 is,
⇒ 4x³
⇒ 4 × 1³
⇒ 4
The value of expression at x = 2 is,
⇒ 4x³
⇒ 4 × 2³
⇒ 4 × 8
⇒ 32
The value of expression at x = 1/2 is,
⇒ 4x³
⇒ 4 × (1/2)³
⇒ 4 × 1/8
⇒ 1/2
Thus, The value of expression at x = 1 is, 4
At x = 2 is, 32
At x = 1/2 is, 1/2
