Answer:

x > -4

Step-by-step explanation:

Isolate the variable, x. Treat the greater than sign like a equal sign, in that what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 7 from both sides:

3x + 7 (-7) > -5 (-7)

3x > - 5 - 7

3x > -12

Next, isolate the variable, x, by dividing 3 from both sides:

(3x)/3 > (-12)/3

x > (-12)/3

x > -4

x > -4 is your answer.

f(x) + n - shift a graph of f n units up

f(x) - n - shift a graph of f n units down

f(x + n) - shift a graph of f n units left

f(x - n) - shift a graph of f n units right.

f(x) = x³, g(x) = (x - 2)³ - 3 = f(x - 2) - 3

2 units right and 3 units down.

If a 10-pound sack of potatoes costs $6.55, how much would 1 pound cost? Round your answer to the nearest cent.

Black_prince [1.1K]

$\begin{array}{ccc}10\ lb&-&\$6.55\\\\1\ lb&-&\$ x\end{array}\ \ \ |cross\ multiply\\\\\\\\10\cdot x=1\cdot6.55\\\\10x=6.55\ \ \ \ |divide\ both\ sides\ by\ 10\\\\x=\frac{6.55}{10}\\\\x=0.65\underline{5}\approx\boxed{\$0.66}\\$

If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up (+1).

Write the slope intercept form of the equation with slope 8 and y intercept (0,7)

Elanso [62]

Answer:

y=8x+7

Step-by-step explanation:

Use the form y=mx+b

M= the slope

B= the y-intercept

y=8x+?

Since the y coordinate of (0,7) is 7

b=7

So y=8x+7
