Answer:

The graph is attached below

Step-by-step explanation:

y < -2x-4

To graph the given inequality, replace < symbol by = sign

y = -2x-4

Now make a table

Assume some random number for x  and find out y

x                y= -2x-4

-1                -2

0                 -4

1                  -6

now we graph the points . Use dotted line to connect the points

Now we do shading

Use test point(0,0)

y < -2x-4

0

False

So we shade the part that does not contain (0,0)

Write an equation of a line in slope-intercept form that passes through the point (-2, 4) and has a slope of -3. (no spaces in y
mrs_skeptik [129]

Answer:

y = - 3x - 2

Step-by-step explanation:

Step 1:

y = mx + b     Slope Intercept Form

Step 2:

y = - 3x + b     Input Slope

Step 3:

4 = - 3 ( - 2 ) + b     Input x and y

Step 4:

4 = 6 + b     Multiply

Step 5:

- 2 = b       Subtract 6 on both sides

Answer:

y = - 3x - 2

Hope This Helps :)

Solve the following system. x2 + y 2= 25 2x + y = 10 The solution set
anzhelika [568]

Answer: {(5,0), (3,4)}

Step-by-step explanation:

You can apply the Substitution method:

- Solve for y from the second equation.

- Substitute into the first equation and solve for x.

Then:

y=10-2x

x^2+y^2=25\\x^2+(10-2x)^2=25\\

(Remember that: (a\±b)^2=a^2\±2ab+b^2)

x^2+(10^2-2(10)(2x)+(2x)^2)=25\\x^2+100-40x+4x^2=25\\5x^2-40x+75=0\\x^2-8x+15=0\\(x-5)(x-3)=0\\\\x=5\\x=3

Substitute the values obtained into one of the original equation and solve for y:

2(5)+y=10\\10+y=10\\y=0\\\\2(3)+y=10\\6+y=10\\y=4

The solution set is: {(5,0), (3,4)}
