Answer:
−2x−28
Step-by-step explanation:
Distribute:
=(−4)(x)+(−4)(6)+(2)(x)+(2)(−2)
=−4x+−24+2x+−4
Combine Like Terms:
=−4x+−24+2x+−4
=(−4x+2x)+(−24+−4)
= −2x - 28
Answer:
c. 11
Step-by-step explanation:
36 divided by 3.25 is a little over 11. That little extra is a remainder and cannot be put into 3.25 again, and so 11 is the right answer.
Answer:
560 is the volume
Step-by-step explanation:
12x2 + 6x -8 is a quadratic equation so divide each term by 4x
answer 4x times (3x + 3/2 - 2/x) This means the base is (3x + 3/2 - 2/x)
x - 4 = -8 <em>add 4 to both sides</em>
x = -4
<em>Put the value of x to the first equation 3x - 12y = -6:</em>
3(-4) - 12y = -6
-12 - 12y = -6 <em>add 12 to both sides</em>
-12y = 6 <em>divide both sides by (-12)</em>
y = - 0.5
<h2>
Answer: x = -4 and y = -0.5</h2>
New question:
x - 4y = -8 <em>add 4y to both sides</em>
x = 4y - 8
Substitute it to the first equation:
3(4y - 8) - 12y = -6 <em>use distributive property</em>
(3)(4y) + (3)(-8) - 12y = -6
12y - 24 - 12y = -6
-24 = -6 FALSE

Answer: No solution.</h2>
