Answer:

Variable: x

Coefficient: 5

Exponent: 2

Constant: 7

Step-by-step explanation:

We have been given an expression 5x^2+7. We are asked to match each term with correct option.

Variable: We know that variable is a value that is not consistent. It can change. The variables are mostly defined as letters like a,b ,c, x or y.

We can see that in our given expression the variable is x.

Coefficient: We know that a coefficient is a quantity multiplied by the variable. We can see that 5 is multiplied by x, therefore, 5 is coefficient.

Exponent: Exponent means a quantity or variable raised to a power. We can see that x is raised to second power, therefore, exponent is 2.

Constant: A quantity which remains same or which never changes.

We can see that 7 is constant for our given expression a sit remains same.

Answer:

It's y = (5)(0.2)^x

_____________

Step-by-step explanation:

Exponential functions have a standard form of ab^x

Where a is the starting value, and b is the exponential growth or decay.

Because the numbers are getting smaller and smaller, it is a decay so b must be less than one.

We can eliminate the first choice because when x is 1, y is 1. If this where the equation we would get (5) (1/2) ^ 1 = 5 × 1/2 = 2.5 ≠ 1.

So the answer must be the second choice.

<h2>120 Pennies</h2>

Step-by-step explanation:

First, we need to find 80% of 400

400 x 0.8 = 320

Now 50% of 400 is 200

320 - 200 = 120
