The correct answer is C. A linear equation is written in y=mx+b, which this equation can be. y=3-4x is the same as y=-4x+3, which is a linear function.

Evaluate the function at the indicated values. (If an answer is undefined, enter UNDEFINED.) f(x) = 8x + 9 f(1) = f(−2) = f 1 2

creativ13 [48]

Answer:

f(1)=17

f(-2)=-7

$f(\frac{1}{2})=13$

Step-by-step explanation:

We are given that a function $f(x)=8x+9$

We have to evaluate f(1),f(-2) and $f(\frac{1}{2})$

Substitute x=1 in the given function then we get

$f(1)=8(1)+9=17$

f(1)=17

Substitute x=-2 in the given function then we get

$f(-2)=8(-2)+9=-16+9=-7$

f(-2)=-7

Substitute $x=\frac{1}{2}$

Then we get

$f(\frac{1}{2})=8(\frac{1}{2})+9=4+9=13$

$f(\frac{1}{2})=13$

An account pays 8% per year simple interest. In year 1, the amount in the account is $850. How much is in the account in year 6?

loris [4]

In year 1 : $850

Simple interest = P * n * r

P = $850, n = 1 ( one year ), r = 8% = 0.08

850 * 1 * 0.08 = $68 ( interest for one year)

In year 6 the amount is:

850 + 5 * 68 = 850 + 340 = 1190

Answer:

A ) $1190.00

$: \implies \sf 31 = \dfrac{15 + x}{7}$

$: \implies \sf 31 \times 7 = 15 + x$

$: \implies \sf 217 = 15 + x$

$: \implies \sf x = 202$
