Assume that we have 4x² - 8.
There are many way to describe it.
• 4x² - 8 is a binomial because that expression has two terms.
• It's also a polynomial because it consists of many finite number of terms!
On the other hand if you really meant 4*2-8 then the answer is 0
It's best if you include some details for the question you have asked. Thank you!
-4x=7y-28 -4x+28=7y -4x/7+4=y A line with a y-int of 4 and a slope of -4/7
8x-5=23+4x 8x-5-4x=23+4x-4x 4x-5=23 4x-5+5=23+5 4x=28 4x/4=28/4 x=7
28
3x + 7 = -4x + 28 implies 7x + 7 = 28
4x-6=22, 4x=28, 4/4(x)=28/4, x=7. That is how you get the answer to be 7
4x-28 = -24
-4x=7y-28 -4x+28=7y -4x/7+4=y A line with a y-int of 4 and a slope of -4/7
8x-5=23+4x 8x-5-4x=23+4x-4x 4x-5=23 4x-5+5=23+5 4x=28 4x/4=28/4 x=7
Well take your pick either 4x-7 = -28 .... -28 -2 = -30 .... -30x5 = -150 or 4x-7 = -28 .... (-2x5=-10) .... -28-10 = -38
4x - 6 = 22 Therefore, 4x = 28 x = 28/4 x = 7
If you mean: 3x -7 +4x = 28 then the value of x works out as 5
To answer this, first convert it into an equation: (4)(x+7) = -36 Now, solve for x: (4)(x+7) = -36 4x+28 = -36 4x = )-36)-28 4x = (-36) + (-28) 4x = -64 x = (-64)/4 x = -16
Divide 28 by 4. X = 7
3x - 7 + 4x = 28 7x - 7 = 28 I added 4x and 3x to get 7x 7x = 35 I subtracted 7 from both sides x = 5 I divided by 7 on both sides
4(x - 7)
28
x = -7
