3(x+2)<2(x-1) solve this inequality

1 answer:

8 0

For example, if x is 3. then 3(3+2=5),3*5 is 15. 2(3-1=2),2*2 is 4. so, if it says that 2(x-1) is greater than 3(x+2), then this inequality is most likely false.

Use the table below to find f ( 4) - f (0) + f(-8), Choose your correct response from the options below.

Answer:

-4f

Step-by-step explanation:

Hi! Let's work on simplifying this.

f(4) = 4f

f(0) = 0, because anything x 0 is 0

f(-8) = -8f

Our equation is 4f + -8f

We can get rid of the plus negative...

4f - 8f

So we get:

-4f

13x + 15=17x-13 solve for the solution

Archy [21]

Answer: x=7

Step-by-step explanation:

Step 1: Subtract 17x from both sides.

13x+15−17x=17x−13−17x

−4x+15=−13

Step 2: Subtract 15 from both sides.

−4x+15−15=−13−15

−4x=−28

Step 3: Divide both sides by -4.

−4x/−4 =−28/−4

x=7

If the sum of the roots of the equation 3x² + kx + 1 = 0 is 7. then what the value of k

koban [17]

Answer:

The value of k is -21

Step-by-step explanation:

ax² + bx + c = 0

Sum of the roots = -b/a

3x² + kx + 1 = 0

= sum of the roots = -k/3

-k/3 = 7

Now, Multiply both side by (-3) we get,

(-3)-k/3 = 7(-3)

k = -21

Thus, The value of k is -21
