Range = (-27, -7, -2, 8, 48)
Answer:
2x-y=2
Step-by-step explanation:
first, the easiest thing to do is multiply the whole thing by 3, since the fractions's denominators are the same.
you should get:
2x -y = 2
standard form formula = Ax + By = C
so luckily, the equation above we just solved is already in standard form after multiplying everything by 3
<em>remember</em><em> </em><em>that</em><em> </em><em>in</em><em> </em><em>standard</em><em> </em><em>form</em><em>, </em><em>A</em><em> </em><em>cannot</em><em> </em><em>be</em><em> </em><em>negative</em><em>, </em><em>and</em><em> </em><em>we</em><em> </em><em>can't</em><em> </em><em>have </em><em>any</em><em> </em><em>fractions</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>equation</em>
Answer:
b = 7, c = -44
Step-by-step explanation:
If the quadratic equation has the solutions -11 and 4, the two factors are:
Since when we use the zero factor property we get
x+11=0 ⇒ x= -11
x-4=0 ⇒ x=4
Thus, we have used the zero factor property in reverse to find the factorization of the quadratic equation.
Now we develop the multiplications between parenthesis:
So b is the number that accompanies the x: b = 7
and c is the independent number: c = -44
8x - (5x + 4) ≥ -31
8x -5x - 4 ≥ -31
3x ≥ -31 + 4
3x ≥ -27
x ≥ - 9
Answer: a numbe line with a circle on - 9 and shading to the left.
Because that drawing represents the number that are less or equel than -9 and the answer is the numbers greater or equal than -9.
