Cross multiply the denominator with 2 to get
3x -1 = 2(x-4)
3x - 1 = 2x - 8
x = -7
Answer:
○ 
Step-by-step explanation:
This system of inequalities has a shared portion at the origin, so we can easily jump to using the zero-interval test [test point (0, 0)] to verify the inequalities as false or true:
☑
☑
Plus, the top inequality has a <em>dashed </em><em>line</em><em> </em>["<" or ">"], and the bottom inequality has a solid line, so this must have an equivalence line underneath each inequality symbol ["≤" or "≥"].
** Hold on though! Although it looks obvious about what the second inequality is, we need to double-check and make sure anyway, just to be on the safe side ☺:

From the y-intercept of
we do
by either moving four blocks <em>north</em><em> </em>over five blocks <em>west</em><em> </em>or four blocks <em>south</em><em> </em>over five blocks <em>east</em><em> </em>[<em>west</em> and <em>south</em> are negatives]. This IS what our solid graph looks like, so we are correct!
So, from all what was explained, you have your answer.
I am joyous to assist you anytime.
First, convert 3 1/2 into an improper fraction, which is 7/2. Now, you have to make sure both sides have a common denominator. This will be 6. So now the equation is 21/6 - 4/6. Subtract the numerators, which is 17. Keep the denominator, however. Now, simplify. You new answer will be 2 5/6.
Answer:
easy peasy
Step-by-step explanation:
we have, area = 497 sq. units
that is, (pi) (radius)^2=497
=> (22/7) x r^2 = 497
=> r^2 = 158.13
=> r = √158.13
=> r = 12.57
now we also have radius, soooo
=> circumference = 2 (pi) (radius)
=> (2) (22/7) (12.57)
=> 79.01 inches

Step-by-step explanation:

When x = -1
Substitute x = -1 into y = 2x
y = 2(-1)
y = -2
( -1, -2)
When x = 3
Substitute x = 3 into y = 2x
y = 2(3)
y = 6
( 3, 6)
