7x + 2y=-12 Y=-3x-4

Answer:

x=-4

Step-by-step explanation:

X would be -4 because if you distribute 2 to (-3x-4) it would give you (-6x-8) and then collecting like terms you would get (x-8=-12)  then you would add 8 to -12 whih would equal -4.

Is -6.175 is an irrational number?
kipiarov [429]
No.

Any number you can write completely is a rational number.
Any number with a repeating decimal fraction is also a rational number.
___
Any number that goes on forever without repeating is an irrational number. These are usually represented symbolically (because they cannot be written "exactly" any other way). These include such numbers as √2, π, e, ∛(-4), and an infinite number of others.

Which ordered pairs lie on the graph of the exponential function f(x)=-3^2x+5
Shtirlitz [24]
You don't really know where the x is. The way you have written it, technically its like this. (-3^2)*x and none of the answers agree with that.

It must be -3^(2x) + 5 In that case 0,4 works. That gives (-3)^0 = -1
-1 + 5 = 4
Unfortunately so does 1,-4 because -3^2 = - 9 
- 9 + 5 = - 4

If (-2,76) is the answer, then the question should be written (-3)^(2x) - 5 

Until the ambiguity is gone, we're not sure.

A store has a 40%off sale on headphones. With this discount, the price of one pair of headphones is $36. What is the original pr
Murrr4er [49]
The discount is 40% that means the discount is 40% off from the original price. Or we could write the discount as below.
discount = 40% × original price

Find the original price
original price = sale price + discount
original price = 36 + 40% original price
100% original price = 36 + 40% original price
100% original price - 40% original price = 36
60% original price = 36
0.6 original price = 36
original price = 36/0.6
original price = 60

The original price of the headphone is $60

Add. 5 1/8 + 5/6 + 5/12. <br><br>A) 6 3/4<br><br>B) 6 3/8<br><br>C) 6 3/12<br><br>D) 6 3/24
djverab [1.8K]
Let’s change all of the denominators to be 48. He now have 6/48+40/48+20/48, or 66/48. This becomes 33/24, and in total 5+33/24, or 6 and 9/24. 9/24 becomes 3/8, so your answer is B.
