slope is -1

y-int is -2

its in y=mx+b form

b is the int

m is the slope

Remember from now on ,

The coefficient of x in slope-intercept form ( y = ax + b ) of the linear equations, is the slope of the line.

Thus : y = -1 ×( x ) - 2

The coefficient of x in the above function is - 1 so the slope of the above function is - 1 .

_________________________________

To find the y-intercept of any equations we have to put 0 instead of x in the equation and solve the equation to find the value of y which is the y-intercept of our equation.

y = - x - 2

put 0 instead of x

y = - 0 - 2

y = - 2

Thus the y-intercept is - 2 .

Find the simple interest earned to the nearest cent for each principal, interest rate, and time.

mafiozo [28]

Answer:

for the first one its I=38.40 for the 2nd one its $315

Step-by-step explanation:

Simple interest , I, is calculated by multiplying the principal, P, by the rate,r, by the time, t, in years:

I = P * r * t

Here, P = $640

r = 0.03 (decimal value for 3%)

t = 2 years

The interest will be:

I = P * r * t

I = 640 * 0.03 * 2

I = $38.40

2nd one:

We know, Interest value = P * R * T /100

Here, P = 1500

R = 4.25

T = 4

Substitute their values,

I = 1500 * 5.25 * 4 / 100

I = 31500 / 100

I = 315

In short, Your Final Answer would be $315

3rd answer:

assuming you subtract 2% of 580 a month for six months. your remaining money would be $510.40

because you subtract $69.6 from 580

4th answer:

$1231

Step-by-step explanation:

Given,

Principal amount = $1200

Rate of interest = 3.9%

Time = 8 months or (8/12) 0.666667 years

Formula of simple interest =

A = 1200(1+(0.039 × 0.666667))

A = 1200 (1+0.026)

A = 1200 (1.026)

A = $1231

Graph the solution to the following linear inequality in the coordinate plane 5x-y>-3

Irina18 [472]

Answer:

Here's one way to do it

Step-by-step explanation:

1. Solve the inequality for y

5x - y > -3

-y > -5x - 3

y < 5x + 3

2. Plot a few points for the "y =" line

I chose

$\begin{array}{rr}\mathbf{x} & \mathbf{y} \\-2 & -7 \\-1 & -2 \\0 & 3 \\1 & 8 \\2 & 13 \\\end{array}$

You should get a graph like Fig 1.

3. Draw a straight line through the points

Make it a dashed line because the inequality is "<", to show that points on the line do not satisfy the inequality.

See Fig. 2.

4. Test a point to see if it satisfies the inequality

I like to use the origin,(0,0), for easy calculating.

y < 5x + 3

0 < 0 + 3

0 < 3. TRUE.

The condition is TRUE.

Shade the side of the line that contains the point (the bottom side).

And you're done (See Fig. 3).
