HELP ASAP
denis-greek [22]
A) I included a graph, look below.

B)

Input the y in x = y + 3.

x = (-4x - 3) + 3
x = -4x + 0
Add 4x to both sides.
5x = 0
Divide both sides by 5.
x = 0

Input that x value in y = -4x - 3

y = -4(0) - 3
y = 0 - 3
y = -3

(0, -3)

C)

Convert both equations to Standard Form.

x = y + 3
Subtract y from both sides.
x - y = 3

y = -4x - 3
Add 4x to both sides.
4x + y = -3

Add the equations together.

4x + y = -3
x - y = 3
equals
5x = 0
Divide both sides by 5.
x = 0

Input that into one of the original equations.

0 = y + 3
Subtract 3 from both sides.
-3 = y

(0, -3)

Find the area of the shape shown below.
sveticcg [70]

Answer:

A = 15u²

Step-by-step explanation:

Area of a Trapezoid Formula:

\frac{h}{2}*(b_1+b_2)

Plug in our values (h = 3, b1 =  7, b2 = 3)

\frac{3}{2}*(7+3)

Now we evaluate

\frac{3}{2}*(10)

\frac{30}{2} = 15

malfutka [58]
Well, bearing in mind that, a year has 12 months, so 18 months is really just 18/12 of a year, or 3/2 a year, then

\bf \qquad \textit{Simple Interest Earned Amount}\\\\&#10;A=P(1+rt)\qquad &#10;\begin{cases}&#10;A=\textit{accumulated amount}\\&#10;P=\textit{original amount deposited}\to& \$900\\&#10;r=rate\to 4\%\to \frac{4}{100}\to &0.04\\&#10;t=years\to \frac{18}{12}\to &\frac{3}{2}&#10;\end{cases}&#10;\\\\\\&#10;A=900\left( 1+0.04\cdot \frac{3}{2} \right)
