x=3.5
This is how I did it I took the bottom 2, 3 and 2.4 and I divided 3 by 2.4 (3/2.4) and got 1.25. I then multiplied 2.8 by 1.25 and found that x was 3.5
Answer is C. 3.5
<h3>Answer:</h3>
c) there are infinitely many solutions
<h3>Explanation:</h3>
Add x to the <em>first equation</em> to put it in standard form:
... x + y = 3
Divide the <em>second equation</em> by the common factor of all terms, 2, to put it in standard form:
... x + y = 3
These two equations describe the same line. Every point on the line is a solution to both equations, so there are infinitely many solutions. (We say these equations are "dependent.")
Answer:
y=-7x-9
Step-by-step explanation:
y=mx+b(where m is slope and b is y intercept)
y=-7x+b
plugging the number in we get
12=-7(-3)+b
12=21+b
b=-9
so y= -7x-9

To turn a decimal into a fraction move the decimal point two spots over (Ex: 0.34=34%). To turn a fraction into a decimal get the denominator to 100 by multiplying both the top and bottom by whatever number needed (must both be multiplied by the same number) or divide to top number into the bottom number of you can’t multiply.
