Answer 1

Answer:

D.) This system has infinitely many solutions

Step-by-step explanation:

y = -4x - 6

-4x - y - 6 = 0

-y = 4x + 6

-y/-1 = 4x/-1 + 6/-1

y = -4x - 6

There are infinitely many solutions, because both of the lines are exactly the same. As show below ! Hope this helps once again ^w^

Answers

Answer:

x = 5 22/24 OR x = 5 11/12

Step-by-step explanation:

x - 3/4 = 5 1/6

To solve this we mush use inverse operations

x - 3/4 + 3/4 = 5 1/6 + 3/4

x = 5 22/24

x = 5 11/12

To add the fractions there has to be a common denominator.

1/6 x 4/4 = 4/24

3/4 x 6/6 = 18/24

Keep denominators the same and add the numerators.

If your teacher wants the answer not simplified the answer is

x = 5 22/24

If your teacher wants it simplified the answer is

x = 5 11/12

I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!

Area of triangle:

A= 1/2*b*h

= 1/2 *(29)* (19)

= 1/2 *(551)

= 275.5 in^2

Area of rectangle:

A= l * w

= (29) * (10)

= 290 in^2

Total Area:

275.5 + 290 = 565.5 in^2

Hope this helps! Have a great day :)

Answer:

565.5 in

Step-by-step explanation:

The area for a rectangle is A = lw

So A = (29)(10)

A = 290

The area for a triangle is A = 1/2bh

So A = 1/2(29)(19)

A = 1/2(551)

A = 275.5

You combine the two numbers to get a total area of 565.5 in
