Which graph below shows a line that contains ordered pairs that are solutions of the equation shown?
Vinvika [58]

Given:

The equation is:

y=-x+4

To find:

The graph of the line that contains ordered pairs that are solutions of the given equation.

Solution:

We need to find the graph of the given equation.

We have,

y=-x+4

At x=0, we get

y=-0+4

y=4

So, the x-intercept of the given equation is at point (0,4).

At y=0, we get

0=-x+4

x=4

So, the y-intercept of the given equation is at point (4,0).

From the given graphs it is clear that the line in option C has x-intercept at point (0,4) and y-intercept at point (4,0).

Therefore, the correct option is C.

Suppose you invest $2250 in a D that earns 3% APR and is compounded monthly. The Cd matures in 2 years. How much will this CD be
olasank [31]

Answer:

$2388.95

Step-by-step explanation:

  • Principal, P= $2250
  • Annual Interest Rate, r= 3% =0.03
  • Time, n= 2 years
  • Since it is compounded monthly, Period, k= 12 Months

The worth of a compound deposit after a period of n years is calculated using the formula:

A(n)=P(1+\frac{r}{k})^{nk}

A(2)=2250(1+\frac{0.03}{12})^{12 \times 2}\\\\=2250(1+0.0025)^{24}\\=2250(1.0025)^{24}\\=\$2388.95

At maturity, the deposit will be worth $2388.95.
