Solve for x. −4≤16−4x
Nitella [24]

Answer:

the answer for x<5

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

−4<−4x+16

Step 2: Flip the equation.

−4x+16>−4

Step 3: Subtract 16 from both sides.

−4x+16−16>−4−16

−4x>−20

Step 4: Divide both sides by -4.

−4x

−4

>

−20

−4

What is the solution to the linear equation? 2/3x-1/2=1/3+5/6x
creativ13 [48]
2/3x - 1/2 = 1/3 + 5/6x....multiply the entire equation by the common denominator of 6...this will get rid of the fractions.

6(2/3x - 1/2) = 6(1/3 + 5/6x) =
4x - 3 = 2 + 5x...subtract 5x from both sides
4x - 5x - 3 = 2...add 3 to both sides
4x - 5x = 2 + 3...combine terms
-x = 5...multiply by -1 to make x positive
x = -5

Suppose f(x)=x^2. what is the graph of g(x)=1/3 f(x)
saw5 [17]

Step-by-step explanation:

f(x) = x^2

g(x)= 1/3 f(x) = 1/3 x^2

First lets make a table for f(x)= x^2

Lets pick some numbers for x  and find out y

x           y=x^2

-3           (-3)^2 = 9

-1              1

0             0

1              1

3             9

Now we use the same x  values and make a table for g(x)

x         g(x)= \frac{1}{3} x^2

-3          g(x)= \frac{1}{3}(-3)^2=3

-1          g(x)= \frac{1}{3}(-1)^2=\frac{1}{3}

0             0

1           g(x)= \frac{1}{3}(1)^2=\frac{1}{3}

3          g(x)= \frac{1}{3}(3)^2=3

Graph the above table
